I was genuinely disappointed by Hambinis response to my original video. I not only lost my respect for him, I also felt that if he was a credible and honourable man he would not have needed to fake information and cut my video to hide evidence to refute me?
If he had simply admitted that he got 1 small thing wrong, we could have ended things there. My respect and faith in him as a credible source would have been strengthened… sadly it didn’t go that way, so get ready…

I never would have thought that two mechanics arguing would be the peak of YT entertainment, but here we are, and I salute you.
Could not have said it better!!😂😂
Thank you. 🙏🏻
But Hambini is an engineer
Hambini is as much a mechanic as much an A-10 Thunderbolt II is for air to air missions - easy to overlook for the uninitiated
@@esm7708 - true and engineers tend not to be the best of technicians. But he is pretty damn good since I have been both.
This is great. I never thought I would find drama in the bicycle bearings community.
Cool 😎
Hambini cannot throw his pride and accept that everyone has his limit. Someone cannot accept his wrong will not learn to make things right. Great work Reginald.
Thank you kindly! 🙏🏻
What in the hell do you know about it? This is a silly argument from the start. Does a special puller do better? Probably, but a hammer and punch used carefully work fine.
The preload tube maintains the correct distance between the two bearings when the ancillary axle components are tightened. They are therefore designed to tolerate the crushing forces applied to the bearing when its tightened between the forks. I doubt therefore, the puller would do any damage to the preload tube. As I said before bearings are made with a chamfer specifically for instances where internal pullers are needed. Hambini is simply wrong.
Thank you and yes that’s a very logical point I hadn’t considered. 👍🏻
I lost respect for Hambini when I realized he was a sexist troll.
He full on verbally attacked a female journalist for like no reason. Sexist is like “women can’t drive” what he did is way beyond that in my humble opinion.
That certainly clarified the situation. And I appreciated the heads up on the useful dt swiss tools. Great
Go to Tool box wars on IG, it’s tool heaven! ❤️
The official technical manual for the DT Swiss 350 thruaxle front hub does actually show using a hammer and punch to remove the first bearing. See page 8 of their current “HUBS TECHNICAL MANUAL FRONT 350, 370”. (I tried linking directly to it but I think my first post was blocked because of the link?)
I think for many other variants of their hubs (including the matching rear hub of the above mentioned one) they do recommend using the axle to drive out the first bearing as you show in your video. But for the style of hub in your original video I think Hambini is technically correct that DT Swiss does recommend a hammer and punch.
So far I have never changed the bearings in my 350 hub. But I have been considering buying a puller of some sort when the time comes. I have never liked the idea of the hammer and punch method.
It has been very interesting watching yours and the 5 year old’s videos on this!
The hub type Hambini showed in his video was the type that used the axle to remove the bearings and was the same one I demonstrated.
Yes sometimes they do show using a punch and hammer but it depends on the hub type, age of the manual, target audience and so on.
My argument was that it’s less damaging to use a puller and that nowadays they make better tools for the job, I found several special bike tools that have been designed to remove bearings from hubs with the preload tube without the use of a hammer. You will see one of them at 25:36 but there are others.
Punch and hammer is the easiest way, but my argument is it’s the worst choice if other options are available and that a puller will do that job quite a bit safer for all components concerned. 🙂👍🏻
Thank you for your comment! 🙏🏻
tbh i think hambini needs to concentrate on banging his hair dresser and leave engineering to the grown ups !
That sounds quite disturbing when you re-read it. 😳
Are we talking about engineering or mechanical fitting because theres a difference here. You can be an engineer/ academic with hardly any hands in fitting experience or you could be an engineer with lots of hands on fitting. A decades experienced mechanical fitter will have ways and means of repairing and servicing often beyond an engineering graduate that's pretty much an accepted position. In the end they are separate roles in a connected work field/industry that overlap and rely on each other. Hambini is first an foremost a designer, inventor, calculations man that's the crux of an engineer which from my limited observation seems to be done well.
As a professional mechanic who has to fix mistakes of "engineers" when they attempt something they are out of their depth in, thank you! Hambini clearly is a very fragile person. He is a microcosm of what's wrong with the world today. Someone gets popular and uses their influence to pad their ego and attack others instead of using it in a productive manner.
Yes, becoming famous and loved is very dangerous to your mental stability.
Thanks for the comment. 👍🏻🙂
@@reginaldscot165 BTW have you checked out Noble Wheels' new tool designed specifically for the problem this whole saga started on? 😅
@@reginaldscot165 I have one on preorder for my shop already. I love what he is doing for the industry!
'Twat' was the word you were looking for,.Actually one he'd probably use himself, to describe himself.
Attacking someone's ego with an ego of your own is a sign of weakness. There are ways and means to prove your point that don't involve attacking where all parties involved can benefit (including us viewers). Don't let "RUclips" fame get to your head.
Well I will try to take this psychological analysis as constructive. However I would say that my reaction is a direct result of Hambini actively lying about me, my tools and my ability in his response. So I called him out for it in a hard hitting yet humorous manner. 🙂
Thank you for your comment. 🙏🏻
Probably best to just leave it there before he attemps to pull a move like he did on cycling weekly.. A deeply unpleasant character who would make for an awful colleague if he carries on like that in the workplace.
Agreed 👍🏻
Ham has made a name for himself bashing others .. and now someone finally has the balls to return the favor .. karma is a bitch eh
Yes I must be mad! 😂
Not trying to fanboy him but more like he made a name calling out companies (or big velo as they call them), I don't know individuals though - he rails against the shrills such as GCN and cycling weekly
After all, if you spend £2000 plus on a bike, wouldn't you expect so much for your cash
Not going to lie... I'm TOTALLY here for this. Having studied mechanical and aerospace engineering, I'm always down for exposing egos who have themselves become the biggest tool in the shop. That said, ones ego and emotional age tend to develop in inverse proportion, so his response should be pretty epic. 😂
Humm, I’m not looking forward to the response to be honest. I would like to just get an apology and be done with this. 🤷🏻♂️
@@reginaldscot165 I agree completely, but I can't see it being something he's capable of, unfortunately.
@@robertshunter exactly.
You've studied both mechanical and aerospace engineering, where do you work in that field ?
@@glennoc8585 who cares and what business is it of yours? What a weird question.
I've been watching Hambini for years and I always knew to take his stuff with a grain of salt, the ego is huge. I've also noticed inconsistencies and contradictions in many of his videos.
I was far too trusting of him to be honest. Not anymore…
@@reginaldscot165 he uploaded a new video again saying the extractor will damage the preload cylinder, has he actually used it?
If Hambini had any level of maturity and professionalism he’d admit his methods weren’t the best, but he doesn’t possess those qualities. Instead he escalated it and now you’ve had to prove him wrong again.
If he’s any sense he’ll just leave it be at this stage, otherwise this will just be a constant toing and froing and he’ll have to invent more ways to try and make himself appear superior to his fan base.
I think the point is well made at this stage and probably shouldn’t be reiterated further, regardless of whether he responds or not.
I was considering that possibility. I don’t actually want to continue this and I hope we can leave it at this and be done.
The proper line of defense for him would be just to explain how smashing the bearings out is just a "good enough" method. However he can't do that because he is selling overpriced crank hubs for 10x the money similar to actually quite well made stuff that can be had from the Chinese.
To be precise here if done correctly drifting a bearing out will not cause damage to the housing. It is most definitely widely used in industrial settings. So to state that it causes damage is incorrect. It can if done in a ham fisted manner but damage is not a certainty, far from it. I am in agreement with Hope, Peaktorque and Hambini that there is nothing wrong with this method when performed by a competent person. Also you will have noticed that Hope even used a copper and hide deadblow hammer very similar to Hambini. Hope manufacture some of the finest hubs and was founded by ex Rolls Royce engineers if memory serves.
That said when I serviced my Campagnolo Bullet hubs I did indeed use a blind bearing puller however If I didn't have one at hand I would have happily drifted said bearings out , confident that zero damage would have been inflicted upon the internal bore of the hub.
Lots I disagree with here. Firstly your observation is not quite right, Hambini used a copper hammer/mallet, hope used the rubber side of a combination rubber/copper mallet.
The founder of Hope being from RR is basically irrelevant. He might (might) have been an excellent engineer. But what has that to do with their practices today? My point stands, the methods they show for bearing removal is flawed, especially when they had better tools right there on the desk!
Yes punching out a steel bearing from a aluminium hub will (even if very small) cause some damage, as the bearing has to twist! It’s basically impossible to tap it out in an asymmetric fashion without twisting it.
The biggest flaw in your comment is that if you use a puller on your own bike hubs, but think that the hammer method is totally fine… then why use the puller? It’s slower and more difficult. If hitting it with a hammer 🔨 doesn’t do anything bad then why are you wasting your time?
You see, your argument is illogical. 🙂
All the best!
@@reginaldscot165 The hammer that Hope used was a Thor , copper one end , rolled hide the other. Unless I didn’t see correctly as it was on my phone.
A press fit joint by design is a consumable interface, it is accepted that when pressing in the bearing the housing is damaged to a degree as it has to deform, the bearing also depending on the housings parent metal (obviously a minuscule amount). In industry it is common practice for the manufacturer to provide information on how many times you could safely replace a bearing before the housing is deformed out of tolerance and therefore must be replaced.
Drifting out the bearings , if done sympathetically will not unduly exceed the elastic limit of the parent metal, unlike trying to fit a bearing askew.
Yep, Hambini's true character (lack of) is exposed. Thanks for this.
Welcome 🙏🏻
The second I hear someone being condescending in a technical argument in any field of work - it instantly sets off alarm bells for me that they are being disingenuous or their technical argument isn't supported enough and just makes me distrust them more.
Noted 👍🏻
Mr Scott is the most condescending by far
@@Da5idc I don't really remember hambinis video, but was it the one where he suddenly left his usual 5yo tone? If so it's almost as if he knew he was taking a stand on an unstable platform and might seem more believable that way.
I mean he has not given up the tone but instead turned it to 11 when threatened with lawsuits 😅
@@dmrfnk not at all - scotty started it by criticising H for using a punch and hammer to remove a bearing. H replied by showing that a number of bearing manufacturers accept that as a method. H went further to point out that using a blind bearing puller can damage the preload spacer.
Scotty has spent over an hour disparaging H without actually responding.
He needs to retire into a quiet room and wrap his ego in a thick layer of cotton wool
Well done Reginald. Great video. As an old colleague of mine once said, “if he’s an Engineer, I’m an Engine over there”. 😂
😂 Thank you 🙏🏻
I'm not suprised. Hambini seems like the kind of person who is completely incapable of admitting that they could ever possibly be wrong. It must suck to be him. Alternately, you showed a viable, professional technique in the first video, then took constructive criticism, and showed an improvement in this video.
Thank you, yes I’m always happy to hear new and better ideas to implement my systems and skills. 🙏🏻🙂
I have to wonder if you can see what Hambini is doing. What are you arguing? What it appears to me is you are claiming that the Hambini method is damaging the hub. I have been using his method for 40 years and have yet to damage a hub. Granted that a special puller is probably better but I have an entire cabinet full of pullers that worked on ONE special case. The careful use of hammer and punch works in most cases. I see your argument as nothing more than seeking recognition for little to no reason. Why are you arguing over no big deal?
@@tomkunich9401 I'm not arguing anything. I'm stating the fact that Hambini is the kind of guy that thinks he's right all the time, and that everyone else is a complete idiot. In practice, these are the type of people who are wrong or only partially right way more often than they would like everyone to believe.
@@SnootchieBootchies27 - Hambini is a degreed engineer and they are trained to think that they have the best idea. How the hell ELSE do you think they can work? If you think your idea is better just make a video showing your idea of a better way. BTW, you have no idea of how tight that bearing was pressed into the hub that Hambini was knocking the bearing out of. I'm not saying that you may not have a better way but that you are going nowhere criticizing Hambini.
@@tomkunich9401 he's a douchbag, and you won't change my mind on that.
Thanks for this video; very thorough . Unfortunately, it appears that H does not fully understand the importance of integrity in engineering. I think he will come to his senses though, 🙏.
I really do hope so! Thank you 🙏🏻
In pretty much every industry, there is tension between engineers and technicians/mechanics/trades people. I know because I’m an engineer (retired after 40 years in my particular industry). In general, each group fails to respect the knowledge and skills of the other group, so respect is eroded while distrust and tension builds. The most productive and successful teams are made up of those that learn from each other.
Unfortunately, RUclips is a competitive contact sport.
You’re a good man, Reg! Keep up the good work and let Hambini dig his own holes.
Thank you. I have no objection to engineers! My farther is one and I enjoy the videos of peak torque. It’s more to do with ones character rather than profession. 😉
Safe riding!
I have serious doubts that it will change the minds of the die-hard "Hambini fans," but I can't help feeling let down and skeptical about the competence of that "space-aero" guy. His response video was a complete mess, full of emotional outbursts and logical inconsistencies. It really made me question his ability to grasp even the simplest topics he used to excel at. I mean, even his appearance on GCN was more respectable, haha! It takes real decency and courage to admit a minor mistake instead of coming up with pathetic excuses that would undoubtedly ruin his reputation if he didn't have such a devoted fan-base. Right now, I'm seriously contemplating doing my own extensive research and reevaluating topics that seemed crystal clear, like OSPW and ceramic bearings. Who knows, maybe it's also just his five-year-old ego at play, rather than any solid engineering reasoning.
You should follow your gut and do what you feel is right. 🙂
Yes I don’t understand why he did this, it’s professional suicide? All he had to say way “oh look at that! You can pull the bearings! Well that’s me proven wrong, first time for everything I guess! Ok moving on…”
And that would have been the end of it. 🤷🏻♂️
I have used both methods, drift pin and blind puller, it always depends on how much access and clearance is available. Been a mechanic for 50 years.
for example an inner timkin cam bearing on a Harley Davidson, you have to use a blind puller but on a steering head bearing race drift pin is most effective.
Bike or car? Or something else? 🙂 They make some fantastic tools now, you can safely get at any bearing… if you have the money. 😁
How you view things depends on the order you see the videos. I saw Hambini's video first without seeing your original video or his original video and i said he's right. After seeing this video, there's no way Hambini's arguments can stand a chance against yours and you are as right as your wife about him not being handsome :)). As a former Prototyping engineer i can say this: Yes, sometimes you have to improvise and compromise, but you do that only if you DON'T HAVE the proper tool to do the job. Also, IF YOU REALLY HAVE TO damage something in the process and you are aware of it, you damage the least expensive component and the easiest to replace, like the spacer would be in your case, again... IF it was damaged. Shame on Hambini for providing 30% of the information and not admitting there are other better methods to do that job.
Thank you 🙏🏻 Yes unfortunately most people just watched his video and don’t investigate further. You are one of the few that actually took the time to check.
I find this is a wider problem in society, for example many people believe everything the government tells them. Yet they never think to check the other story. I meet people all the time that are so adamant they are right and know the truth based on only 1 sides narrative.
Wouldn’t the world be a better place if more people like yourself took the time to see both sides?
Thank you again and safe riding! 🙂👍🏻
Reginald Scot: It's a shame that Hambini (who I do like) hadn't watched the film of Clear And Present Danger "Lifelong Friends" When Harrison Ford said "no sense defusing a bomb after it's already going off" I thought Hambini was better than that and would just owe it. When you're wrong you're wrong. Hambini must be following the logic of: When he's wrong he is still right!!
I wonder what “logic” he is using. Personally he would have been better off just admitting the small mistake that started all this… instead he chose to lie even more. As the Grail Knight in Indiana Jones says “He chose poorly.”
@@reginaldscot165 I liked your Indiana Jones line “He chose poorly." You wonder what “logic” he was using?? Well he must have been using the same logic my learned friend in London said Lord Denning - (Appalling Vista) used in the controversial judgment in that of the appeal of the Birmingham Six in 1979 when Lord Denning's view was this:
"If the six men win, it will mean that the police are guilty of perjury, that they are guilty of violence and threats, that the confessions were invented and improperly admitted in evidence and the convictions were erroneous... This is such an appalling vista that every sensible person in the land would say that it cannot be right that these actions should go any further. [2]
He also commented that "We shouldn't have all these campaigns to get the Birmingham Six released if they'd been hanged. They'd have been forgotten and the whole community would have been satisfied."
The men's convictions were overturned in 1991, after it was shown that the police had indeed done all the things Denning described, and he admitted that the West Midlands Police force had "let us all down”
I really appreciate that your videos on this subject have spent the bulk of their time focusing on the actual topic under debate. I totally understanding throwing in a couple barbs after the response from both Hambini and his diehard fans, but thank you for not letting your response get unnecessarily mired in them.
Maybe I went too far… but I did not appreciate him actively trying to mislead people.
Thanks for your comment. 🙏🏻🙂
Reginald, I intend to do a Cerakote service on a CeramicSpeed OSPW and I need to remove the pulley bearings... How can I do this without the risk of any damage to the ceramic bearings?
(Note: I just posted a video for you.)
Should not be difficult, once you have the wheels out the bearings are just pressed in if I remember correctly into aluminium (or titanium) wheels.
So as long as you can rest the OD of the bearing seat on something you can push the bearing out. (A vice or a large socket sat on a flat desk) If you don’t have special tools: rest the wheel on an open vice just wide enough to except the bearing, to prevent scratches put a thick cloth over the vice under the wheel, then use a socket of the same size of the bearing to push it out. You can make a simple press tool with a threaded rod, 2 nuts and some washers. Use a set of washers to hook the underside of the vice jaws with the rod coming through the middle of the bearing, then the socket, then a washer then the nut. Hold the bottom nut with a spanner and tighten the top nut wit another spanner until it pushes the bearing out of the wheel. It shouldn’t require much force, if it does something is wrong and check again.
Or if you don’t have that a soft blow hammer with the socket can work, you must hold the parts together firmly to prevent it bouncing and a socket that touches the OD (outer race) of the bearing. Use small gradual taps to drive the bearing out. If you can wait until Sunday I might have time to make a video on this for you as I have a OSPW in the shop now. 🙂👍🏻
Update, the wheel has a bearing STOP on one side, you can only push it out from one side, the wider side. 😁👍🏻
@@reginaldscot165 What excellent help you gave me! I just watched the video! I'm sure it will help many other people!!! 10/10
Absolutely. First. Class. No matter what happens next I'm so glad that this has sparked such in depth and detailed discussion.
Proper geekeery, I'll be keeping my eyes peeled for the follow up!
Are you still on each other's Christmas card lists...?
Ha ha what a wonderful comment! 🤭🙏🏻
Hi Reginald ! Fellow mechanic here. I'm not going to take a side on this "battle" because I don't see the point and I don't have the sufficient experience and knowledge (I'm not an engineer) to do so. I'm not a fanboy of anyone except maybe Calvin Jones, Sheldon Brown, John Allen and Jobst Brandt 😅. Regarding Hope, I agree with you, I don't understand why they use a punch in their video because I asked them a couple of years ago why not using the axle as a bearing extractor and they just replied "Hi Benjamin, You could use the axle, it’s up to you"
I was like "okay...so why don't you show that" :)
I agree with you on the people you named. Excellent people. And yes, sometimes some things in life just don’t make sense and people act like they haven’t noticed? 😂
@@reginaldscot165 On second thought, I'm gonna take your side 😊. I hadn't watched the rest of the video after the Hope part because I had to go to bed, but I have to admit you totally convinced me in the final part of your vidéo.
Brandt and Brown!!! HALL OF FVCKING FAME!!❤❤
G'day Reg, pulling the bearing has to be better than whacking the crap out of them.
The only thing I reckon you done a little bit wrong in part 1 was leaving the rotor on while you were pulling the bearing.
I've only gotta look at em the wrong way and bend out of line. All the best mate👍
Thankfully it didn’t bend, not much weight on it, but yes you are right, it’s good practice to remove it first. 👍🏻🙂
The amount of damage we're discussing here is not worth worrying about. Not worth buying a specific size bearing puller, or employing a bicycle technician who has the puller.
Perhaps. 🤷🏻♂️
In life you have to be willing to be your own worst critic.The funny thing, any mechanic or machinist would tell you specialty tools are out there for EVERYTHING, and a lot of times they'll even make their own when needed. Strong engineering opinions are no substitute for practical experience. Everyone has something you can learn from if you take the time to listen to them carefully. Be humble. Never stop learning.
Excellent advice. 👍🏻🙂
Hambini should be able to afford the correct tools since he claims to be in the field of engineering, right! I have friends who work used to work at bike shops and have the same tools that you use to service just about every part of the bike. Sounds like Hambini just got caught with his ego trip. Hambini always craps on just about every bike manufacturer for their flaws and trying to come out by saying he can make it better one way or another. Question is why is Hambini not working for any of the bike industry manufactures? Honestly dude just can't give take the heat for criticizing his ways. Keep up the good work Reginald!!
Hambini is weird in this way. Dude has an entire manufacturing chain to source materials and fabricate his BBs. But uses a fucking punch on a delicate component.
Thank you! 🙂
I would be very worried to have Hambini designing a paper aeroplane for me ✈️
The thing is, I’m sure he’s good at whatever it is he does, it’s just he can’t admit when he’s wrong. 🤷🏻♂️
The only thing that is flared is Hambinis nostrils after watching this video...
I would think so…
Great response. I always questioned his attack on you. I use some of Hambini's products but I also question some of his statements and posts, it is his USP....
The blatant selling attempt of an illegal road electric bike was a particular low of his a while back😢🤯
Good comment, thank you. 🙂
When I'm spending thousands of dollars on my wheels, I'm sure as hell not bashing the hubs and bearings with a hammer and will be using proper bearing removal tools.
I feel the same way. 👍🏻
I am not an engineer and I do not need to be one. I just need to use my common sence to conclude that hammering things is not good. But if we don't have the tools or don't know what tools to use, we sometimes take the risks of damaging what we are working on. What you showed in you video makes totally sense that even if I am an engineer, I won't dare challenging. Thanks for sharing the possibilities!
You are very welcome. I think people over estimate the power of Qualifications and Underestimate their own ability to use logic and reason to work things out. I’m no expert, I just used the most powerful tool know to man (the internet) and something I learned at school (reading) to do all this. Anyone can do that and I hope they do. 🙂
Amen to that! Internet has a lot of information we can learn from if the writer is to be found credible. If you don't understand the power of credibility, you better become an entertainer or a comedian.
TBH, that hammering is that loud, it's scary if that was your bike
My takeaways from this 'spat'...
- Everyday bike mechanics often know more than the 'experts'
- There's more than one way to skin a cat - what method you use depends on your budget, time pressures, approach to risk etc...
- if someone points out a different/better (!) way to do a job take it with grace and humility
- the experts don't always know best, and sometimes lack integrity
- people in greenhouses shouldn't throw stones - if you're going to make a career/habit of slagging others off be prepared to take it yourself.
- in amoungst all this stuff I've enjoyed learning about the technicalities of product design and maintenance. Would rather have it without the mudslinging though...
Good stuff Reginald - its good to keep us all on our toes. Please don't let to get too personal though - we all need good mental health 👍
Excellent comment, all very good points and yes, on the mental health side I agree… time for a bike ride! 🤭
Hambini is self-taught. He's not an expert. Or at least his knowledge is patchy.
Lol Hambibi belongs in that camp of little knowledge is worse than none. Like many other stated. Great review and you know what you’re talking about 😊 cheers from Oz 🇦🇺
Thank you kindly to the people of Oz! 👍🏻🙏🏻
Great job with the much needed follow up. Thanks!
Thank you
Came over from Hambini’s video response to watch both of yours in order to hear both sides’ arguments. I enjoy Hambini’s reamings, but I was disappointed when I saw your original video and the flush interface between the inner race of the bearing and your puller, which Hambini decided to omit. I agree, your bearing puller wins this one. 🙂 Hambini’s view might of course be justified in the case of a cheapo puller that doesn’t have as nice tolerances as your one does. (I’m a fan of Japanese tools too - I like to carry a couple of Asahi Lightool wrenches for on-the-road maintenance.)
I’m still a basest-of-the-base M475 cup & cone guy when it comes to hubs (can be opened up on the road with simple tools if you absolutely have to, much less attractive to thieves), but prefer Hope’s cartridges on my bottom bracket and headset. I also use the aluminium supports and pusher blocks that Hope provide for disassembly (intended for use with a soft mallet), but have adapted them so that the bearings can be pressed in and out straight and without hammering. 👍 Always my preferred method if I can get away with it, although I love my customized little soft mallet.
The only point I agree with Hambini here is that once you press or hammer a cartridge bearing out, you are most often moving the bearing by applying force on the inner race; it’s generally bad form / not optimal to reuse that bearing since you’ve likely pitted the races a bit, so it should be replaced with a new one. This obviously isn’t an issue, since if you’re removing cartridge bearings, you’re likely to be in the process of changing them anyway. 🙂
Didn’t expect to find this level of disingenuity from Hambini, but hey - you always learn something new.
I’m glad you have the wisdom to look at both sides before casting judgement. Very few people do that unfortunately. Thank you and well done for being open minded. 🙏🏻❤️
The next question would be “if he can be so disingenuous about this subject/video does that make it an outlier or, is this something he does more regularly without me noticing?”
That’s what I asked myself and after I did some research I was shocked by what I found. All the best and safe riding! 👍🏻
@@reginaldscot165 That is indeed the question to ask in cases like these - thought the same thing while watching the videos. Oh well, an additional thing of interest to keep an eye on in the future. And thanks. 🙂
Awesome video and again you are completely correct, starting to make Hambini very in capable I’m so glad I don’t have one his bottom brackets in my bike obviously not well engineered
Great job keep up the good videos
I don’t think his BBs are bad… just over priced whe you consider the other options. 🙂
Ps. Thank you very much!
In my humble opinion Hambini is just showing how you could do most of bike maintenance yourself and not being dependent on bike shops or official tools. The method you think was wrong is also done by one of the videos of BBinfinite. Some tools while good to have are sometimes hard to get and quite expensive if you’re just using it once per year as home mechanics. And who would want to also get charged hundreds 0f $ every time you visit a bike shop to get something done you could do yourself.
When he calls out Reg for talking shit ,that's a different story.
So what will you do when you destroy your hub ? Will Hambini buy you a new one ?
Did you even watch this video? 27:11 goes over this very idea
Hundreds of dollars? Where do you live? Your local bike shop sounds like Rip Off Jane on Rip Off Lane in Moab.

Great work keep on him. I admittedly use the hammer punch method and don't own a blind puller but accept this isn't ideal but I am an IT guy not a bike mechanic or engineer
It’s fine, at the end of the day it is what many people do and it’s your hub so you can do what you like. If Hambini had done it to his own set of wheels I probably wouldn’t have been bothered. 🤭
@@reginaldscot165 Exactly anyway you want to do it is fine but if you are charging to do it you should do it properly with the correct tools and not whinge if you get caught out
As one IT guy to another. Spot on. But I do have a bearing pulling. ;-)
To me, a regular dude who claims to be nothing more than a regular dude, the 'click' in your original video when the jaws snap into place is all the proof I need. If there was no space, then there would be no click..... but I'm just a regular dude so what do I know?
Sometimes people say “because you are only a regular dude you shouldn’t or can’t question a guy who’s got a fancy certificate.” And I think, “but I can read for myself and do my own testing so why not? 🤷🏻♂️🤭
Good reply you have clearly demonstrated that you don't damage the spacer which is the main point of the discussion, personally I think either option is acceptable as long as care is taken when using a punch/drift however a puller where applicable is the better option.
Of course if there was concern over spacer damage then an initial tap with a punch/drift would create a larger gap for a puller to fit into.
I would have preferred if you kept your video to the issue at hand and not cut away to annoying clips that make you less credible and don't get into a slating match over hammer size etc
Keep up the good work and interesting content
Interesting conclusions. Thank you for your input. 🙏🏻
A team of Scotland Yards finest detectives would struggle to recover evidence of Hambini's credibility after this fact checking.
If my experience of UK police is anything to go by then I’m sure you are right. 😂👍🏻
There's reasons why I stopped watching Hambini as an engineer myself. Your videos are showing my decision was solid. Thanks.
I’m glad to have an expert opinion. Thanks 🙏🏻
People get attached to the person rather than the facts. Misguided loyalty ensues. This is how politics is so effective.

Dude I think you're feeding the troll. Just stop. The guy is going to just get more and more toxic. Your original video was way less emotional too. The guy is going to drag you down to his level. You are right, time to move on without letting it get more personal
How dare you call a five-year old toxic! He's just a child. Oh yeah, he's repeating what many manufacturers suggest in replacing wheel bearings too.
Yes I was thinking the same.
@@reginaldscot165 I actually think this 2nd video was a good one. Unless there's something extremely compelling that Hambini puts out though, I don't think you really need a 3rd. That being said, you should expect pretty much everything you put online now to be under a microscope by both him and his cultists.
I would really like to see a Hambini bearing puller next. He should have the tools for making such thing. For those super shallow chamfers and/or radiused corners and straight edged spacers.
Yes why not! 🙂👍🏻
@reginaldscot165 two things to consider. Firstly, the inner diameter of the preload tube is often slightly (not much) but wider than that of the bearings inner race. Especially if an axle needs to slide through. This gap is essential for avoiding galvanic corrosion of the two surfaces and for easy extraction of axle in such cases. Secondly, if you apply force to the preload tube by inserting a puller, it would push up against the opposite bearing which in turn is not locked into place so it thus would move slightly outward giving more room for the bearing puller if needed. Unless the preload axle is being forced against an immoveable obect there would be no damage sustained to it when using a puller. If the bearings are seized in the hub from corrosion or past improper use/installation, chances are the hub is cactus anyway and whatever you do is compromise! Love the video and detailed explanations. I wouldn't have the patience to explain all of this to 5 year olds! You should teach kindergarten
That was an excellent comment. Thank you for your time and view!
Safe riding! 🙏🏻🙂
the only explanation of Hambini's behavior for me is to gain some hype from this topic. because it is clear for everyone else, exclude his funclub members, that your method is much safer and sensible. thank you
I was wondering the same… 🤔
A more likely explanation is that Hambini is the type of person who cannot admit he is wrong. So he doubles-down, obfuscates, and makes sophistic arguments.
I like seeing peer review videos. But you are nowhere near his “peer” lacking 6 or more years of engineering school.
Arguing over how someone holds a hammer is not a scientific review or gives tribute to one’s engineering triumphs.
I think you need to consider the rest of the video. There is more to my critique of Ham than his lack of hammer skills.
However I don’t think my qualifications are a valid argument. Are you suggesting that if you aren’t qualified in something you can’t hold a logic based analysis and opinion on that subject?
So if you aren’t a chef you can’t point out if a meal is burnt? If you aren’t a martial arts expert you can’t say if someone hit you in the face?
I think you are being similar to Andrew Tate fans, they over look his obvious criminal activity because he said a few truths. Hambini told obvious untruths and misinformation in his last video, but you ignore that because he may have provided useful information in the past. 🤷🏻♂️
He was clearly wrong, I proved that with a mountain of evidence. I don’t need to be an engineer… after all, it was a simple child that pointed out the Emperor had not clothes.
I asked him on another video about galvanic corrosion between a carbon frame and the aluminium BB adapter made by him. I'm making and repairing bicycles for more 10 years and I found that galvanic corrosion occurs even using anodized aluminium. Until now, no explanation from Hambini. Some people can't admit when they're wrong. Be wrong it is not an error, error is persist in an error.
I like that expression at the end of your comment. Very thoughtful. 🙂👍🏻
What do you propose to make a BB sleeve from then? Sufficient grease/retaining compound and proper maintenance and cleaning should mitigate galvanic corrosion. Mitigate not completely prevent.
If you have problems w an anodized sleeve that presses in, I’d hate to think what’s happening with the English threaded BB bonded into carbon frames
@@Velodictorian BB sleeve needs be made in stainless steel or titanium. I had problems with aluminium stems on carbon columns forks, aluminium stems with carbon layers, aluminium rivets on carbon frames.
Yes, English threaded BB bonded into carbon frames I had many problems too and saw many top line frames with galvanic corrosion/delamination.
I see two ways to resolve this problem, using stainless/titanium or for the frames use a non electric condutive composite.
@@gerworks Could layer in some Dyneema into the BB since it’s non-conductive. Not sure the bicycle commune would adopt steel BB but I guess if anything the mass is low so it actually may improve handling
@@Velodictorian I use 4 layers of basalt or glass fiber to insulate, but in my case all my laminations are wet lay-up, it is not possible to do it in one-shot. I first laminate the metal parts with basalt/glass, wait the resin to cure and after this I do the carbon lamination. Maybe using prepegs you can do it in one-shot, but I think the bicycle frame makers will not spend more money only for people use a metal sleeve on carbon frames. I dislike any kind of press-fit on carbon, you can not milling composites as metals, precision and wear resistance you can not get on composites as in metals. For this reason Shimano's BB press-fit are made in plastic.
Hambini is a character, he is not a perfect individual: non of us are. Enough of dis bad-mindedness! "The road of life is rocky and you may stumble too,
So while you point your fingers someone else is judging you"-Robert Nesta Marley.
It’s one thing to be wrong, take note of your mistake and admit the error. That’s what a good person does.
It’s another thing entirely to make a mistake, then not admit it, then make a video trying to discredit the person who pointed out your mistake and lie to your audience and falsely information to back up your lie. Then when the person who pointed out the mistake proves conclusively that you are lying again not admitting it and not apologising.
That’s the important distinction. 🙂
All the best and safe riding. ❤️

I would like to put my tuppenny thought in if I may.... background first, I am a retired highly skilled engineer with over 30 years experience, I worked within the Aerospace industry, mining machinery industry and also a lot with Rolls Royce so I believe I am somewhat qualified to have an opinion.... while what Hambini says is quite true and bearing can be released with the punch and hammer method why would you risk damaging the housing and not use a puller🤔......a skilled engineer would never choose the first option as the correct way is the right way and any skilled engineer/fitter would always without exception go with the right way...... can't understand why Hambini cannot accept that doing it his way is fine to a point if you haven't got a puller but it is the wrong way essentially just in case.....why risk giving yourself another problem if it goes wrong 😔 I certainly know who not to ask to have a bearing replaced... sorry for the waffling Reginald but it's so obvious which way is the right way
🎊🌟🥳🤩
Thank you Kind Sir. 🙏🏻 My father is/was also an engineer and he is not only a bigger stickler for the rules than myself but he also worked for Rolls-Royce aircraft engines way back in the 80s. He ended up in Robotics (as did I for a few years) and he wouldn’t have approved of me using a hammer. 🔨 “Hammers are not engineering, if you have to hit something with a hammer you are probably doing something wrong…” he would say.
I have only 2 theories as to why he won’t admit his small mistake and argues the point. A) he is not actually a real engineer. B) he is an incredibly petty individual. It is quite disappointing.
All the best and it was good to hear from another experienced person in the realm of engineering. 🙏🏻
So about an hour before you posted this Hambini posted a video where extracted bearings from a freehub using his punch method. So I did a little search on RUclips and found another 4 videos where other people used his method and one where someone used your method but with a slide hammer. The whole issue is quite confusing to me. If the fit is so tight between the inner sleeve and the bearings that you would damage with a puller then how can you just push it out of the way with your finger to use with a punch. And if it's so soft that a puller would damage it then wouldn't one miss hit with a punch do the same. Also if inner sleeve is used for preload then how can it be so soft. I think the bottom-line is that either method will work if you take care but personally I would just try to replace the inner sleeve at the same time as I replaced the bearings.
Some good thinking going on here. 👍🏻
Thank you for the comment 🙏🏻
@@reginaldscot165 you're welcome but my brain is still thinking that inner sleeve is not for preload as much as it's for keeping dirt and debris from getting in behind those bearings as the thru-axle slides in and out thru that sleeve. But I would like to see something from a manufacturer that explicitly stated that before I made that claim.
@@michaelglidewell1524 if you´re still thinking about this (probably not) here´s your answer: The condition of the unmounted wheel might be a little misleading. The tube serves it´s intended purpose in mounted condition. The inner races of the bearings are being pushed together by the torque applied to your wheel axle. As ball bearings are notoriously bad at transmitting axial load from one race to the other, the inner races need the shown spacer to transmit that clamping force from one side of the hub to the other. All elements in this connection (mounting points in frame, spacers, inner races) form a solid conection opposing the force applied by the axle.
If the wheelhub is machined properly, the inner races will now be perfectly in line with the outer races and therefore, there is no sheering force exerted onto the balls and they are left with the radial forces, their intended purpose.
Regarding this series of videos, I think they´re both more right than wrong considering each exclusively shown scenario and both turn a blind eye on the valid arguments of the other. As so often, the truth lies somewhere in the middle. (e.g. using the puller shown in Hambinis video would damage the spacer most likely, using the one here would likely not, simply because of the much finer lip present)
What a petty video… The premise of the argument was how do you remove a bearing that’s internally constrained by a preload tube. Therefore the bearing inner surface is tightly toleranced to the tube (we’re talking micrometer level). If you use a puller, you’ll have to gain clearance to get BEHIND the inner part of the bearing. If you use a puller that expands and you don’t have clearance, you’ll run the risk of flaring the preload tube. This is simple logic, engineering, and common sense. I mean you say that at 28:52 that the tool is “ALMOST completely flush with the inside of the inner bearing surface.” This is an admission that in order to make room for the tool to gain purchase the preload tube would have to yield in some manner.
THE BEST way to remove bearings from this type of system is to use a combination of the methods of punch and press:
1. Gently tap the inner bearing with a punch to gain space between the preload tube and bearing (1 mm should suffice but will depend on the thickness of the lip on the expander)
2. Use bearing press to fully extract bearing
Bob’s your uncle. You’re welcome.
FYI The min radius on the inner surface is 0.3 mm of an SKF bearing. Proper engagement of the expander will put you 0.1-0.2 mm proud of the inner surface of the bearing just due to interaction of the machined surfaces of the tool and bearing.
The proof would be to see your bearing puller expander fully tightened and a straight edge going over the tool and bearing.
I thought the first part of your comment was very petty. 🙂
You basically ignored the original argument. (I included the first 25% of my video for people like yourself just to emphasise the point again.) Yes I use the words almost flush, but if you look at it it’s completely flush. I used almost because nothing is perfect but it’s so close to perfect it makes no difference. Call it a verbal idiosyncrasy.
Second part was almost useful, but I still disagree. Their are better systems available but what you suggest is not it. There is enough space behind the bearing for the puller. It’s just a fact. 🤷🏻♂️
@@reginaldscot165 Put the argument to bed w a straight edge and properly engaged expander in the bearing. If it’s not sitting proud, then there’s the proof.
@@reginaldscot165 And you may want to think twice to get into these petty arguments that drag another through the mud. Under British law, your published statements saying that Hambini “lied” may be construed as libel. English law allows actions for libel to be brought in the High Court for any published statements which are alleged to defame a named or identifiable individual (or individuals; under English law companies are legal persons, and allowed to bring suit for defamation)[19][20][21] in a manner which causes them loss in their trade or profession, or causes a reasonable person to think worse of him, her or them.

@@Velodictorian I have plenty of evidence he lied repeatedly and I’m not under British law.
Are there any bearings that don't have the chamfer for the blind puller to slot into?
I'd like to see you and Hambini discussing this on camera.
Not in the bike industry. Maybe something that was custom made for a very unusual application? But walk in a bearing shop and they are all the same. 👍🏻
@@reginaldscot165 good to know. So the blind puller is always an option should tapping out with the axle (or DT Swiss device) not be possible.
Bearing dimensions incl. inner and outer radius are standardised.
Three weeks ago I commented on the Hambini video "I think we would have to know the exact end configuration of the bearing puller, as expanded, to know who is full of 💩." Now we know who is full of 💩.
I’m at least 50% less full of 💩 😂
Just another point to discredit Hambini's video. It was the other end of the sleeve that appeared damaged, not the end that you allegedly damaged with the tool.
That’s true, that one slipped by me! Thank you. 🙂👍🏻
When Hambini was sexually harrassing Michelle Arthur-Brennans he used the same tactics... he encouraged his viewers to pile on and also send her disgusting messages. He should be careful lest he be caught in a dark alley by someone willing to repay all his favors.
There is a lesson for us all there.
I have a set of HOPE PRO 2 hubs that are fantastic for their ability to be "future-proof" and made me so happy when I upgraded from 100mm x 15mm hollow front / 135mm rear QR axle on my old mountain bike to 142mm x 12mm hollow axles front and rear on my new gravel bike. Unfortunately, their rear axle bearing placement design "seems wrong" or "stupid" when compared to my MAVIC 550, DT Swiss 240s, and Chris King rear hubs. I have never struggled so hard to get new bearngs installed without the Hope specific tools unlike the others hubs that did not need special hub tools. My next hubs are Onyx Vespers to replace the HOPE PRO 2 hubs, not because they are damaged but because they are 12 years old and the HOPE cassette rachet is noisey as f**k!
Reginald could you please produce a video instruction on how to best replace HOPE PRO 2 hubs bearing (if possible) using the bearing puller / pusher shown in these videos or similar without HOPE's special tools? Or have you already made a video like this. I want to keep my HOPE PRO 2 hubs running another 12 years and I have been luckly not to damage them!
Thanks!
Please, I would prefer you not continue this fight with Hambini, simply he is wrong a punch ***COULD*** and, in the hands of an ameteur home mechanic, most likely ***WILL*** damage the hubs. Simply just be the better man. I thoroughly enjoyed the first video but this type (his type) of, lets call it "entertainment", doesn't fly with everyone. BTW he's not lying, he is aged 5 and that's the issue here, never argue with a child, it's pointless.

Why are you making a personal attack when Hambini developed a niche of questioning overpriced engineering failures on expensive bikes? That's a great service to the industry.
@@IronHorsey3 questioning overpriced engineering?? 🤣🤣🤣 Have u seen what he charges for a pipe with cartridge bearings in it?? 😂😂😂

@@IronHorsey3 solution?? 🤔🤔🤔 You do know it's really actually rare to have bb issues?? Seriously who are you
My unqualified thoughts.
There is a gap between the bearing outer surface and the hub inner surface. When you hit the bearing with a hammer you tilt the bearing down the point of force and up the opposite side. If the tilt measurement is greater than the gap between the bearing and hub surfaces then damage may occur. A hard surface (bearing outer surface) is then hitting a soft surface (hub inner surface), this damage may not be visible to the eye(micro surface starches).
Both methods work, the question is which does less damage to o the surfaces. The bearing end needs to be the correct one for the bearings used. I use one that jaws fit inside the bearing and it from the other side. This is not perfect as you could hit the bearing jaws not exactly in the middle, a drift such as the DT would help with alignment.
Good thoughts 👍🏻
The DTSwiss method is a thing of beauty.... And then later DTSwiss let themselves down a little. Kind of sums up this whole debate. We can all improve if we listen to others.
Yes its a shame what they did with the most recent hub design.
I actually believed Hambinis discrediting video until I watched this. I'm now back in your court. Does Mr Hambini have a response video to this one?
No and when he suggested making one his fans said don’t bother you are wrong to him. 😂
Dear Reginald, as a rabid Hambini fan but having been overwhelmed by your loveliness and impeccable rationality I would like to suggest a detente. How about we agree to tap the bearing twice on opposite sides with a very light soft-faced hammer and brass tipped drift sufficient to allow your precious bearing puller to engage with the bearing inner race without flaring the spacer. Then pull the bearing with the precious puller. One other brief word of advice, methinks you protest too much.
How about no, how about you understand that you don’t need to do that because the “puller doesn’t damage the preload tube!” Like I just spent 30 minutes explaining in great detail. 🤦🏻♂️
I agree however you do seem to be rabid… 😁
Unfortunately,Hambini engineering ego got in the way instead of just saying, I f **d up and made a mistake he carried on with a whole bunch of dribble, good job I can’t see him letting this one go doesn’t seem to be in his nature.
It’s sad isn’t it… I hope I don’t allow that to happen to myself. I do say I don’t consider myself as having fans, only viewers and I also say I will get things wrong and I’m happy to improve where needed. 🙂
Thank you 🙏🏻
Reginald, things started with your post on Hambini’s channel:
Reginaldscot: “…it was a little painful watching…” “…not sure why people are sending random wheels to you…”
Hambini: “This is a learning channel, so if I've done something wrong then please chime in!”
You each then have posts explaining your methods/logic, then a post from Hambini:
Hambini: “@reginaldscot165 Can you post a vid? or a link I will look to get one.”
Seven months later you post a video, the content of which I found interesting/informative, and a viewer could take away/evaluate the information to use or not use as their preferred method.
However, the video was titled and filled with your commentary “Hambini Was Wrong”.
In your video you misrepresented what Hambini posted. You said he said “you were wrong” and “refused to believe there was any other way” and that he “challenged” you to make a video to prove.
You had many self-amused chuffing laughs at “proving” Hambini wrong.
You could have presented your method, but instead you trolled his channel and now aren’t happy with his response. You’re “disappointed”, “lost respect”, ad-nauseum. You self-created this “man drama”. I won’t be watching this video or subscribing.
You can remain ignorant if you wish. It is your right to act in any way you see fit and I believe strongly in everyone’s freedom to choose. 🙂👍🏻

I’m no engineer but watching HB hammer that bearing out made my eyes bleed. No finesse. In Ireland we would call that a bog man job I.E. bodge job. I think Reggies methodical approach shows he is a man who considers technique and the nuances of doing things in different ways. Same goes for car mechanics. You can smash stuff out with a hammer but there are also tools to do the job in a much more controlled fashion. I prefer Reggies method. Sometimes ‘specialists’ cut corners because their knowledge and reputation shields them from criticism. Doesn’t make them right though. I see loads of so called pros building bikes and not using a torque-wrench to check the fixings. Yes you can ‘get away’ with not using them but there is a reason why they are recommended by manufacturers.
PS: I did enjoy the editing of the sound check to hammering cuts, did make me chortle 😂
Thank you so much, yes I agree!
Also I miss Ireland, wonderful country with some truly fantastic people. ❤️
That video of Hambini walloping the bearing out made me wince.
Me too
In fairness he didn't wallop anything and the bearing is knackered when it's time to remove them
As my dad would say..."use the right tool for the right job....AND PUT IT BACK WHERE YOU GOT IT!!!"

Same here James 😂
Yes, your bearing puller is correct. Hambini must have a lot of pride, to refute you, although your patronising/condescending approach probably baited him. I do find him to be very rushed and even wreckless with his equipment. I assume that he is self-taught in the workshop.
The only thing that I would change from your method is that after the puller clips into place, screw in the locking bolt, but then don't tighten it, not even finger tight. The puller is in the correct position and does not need to be pushed outwards any more. It only needs to be prevented from slipping out of position, with the 'locking' bolt. By torquing the locking bolt, you 'RISK' doing what Hambini suggests (i.e. damaging the spacer), however if you don't torque the bolt, then this damage can't happen. Torquing the bolt is not needed, barely finger tight is adequate.
Also, this may be semantics but, a Chamfer is a flat corner edge and Radius is a rounded corner edge.
And, I have a reasonable amount of practical experience, and am a chartered mechanical Engineer (Hambini won't be), and found your video informative. I wouldn't have known how to do this task.
Good point there relating to not needing to torque up the puller.
It sounds good, however I have tried that and it doesn’t work, the puller pulls out the hole without the bearing unless you tighten it slightly. But it was a good suggestion. 🙂👍🏻
Simply brilliantly done. I'm sorry but how does a bearing expert and aerospace engineer (any engineer) be so clueless re something so commonly used with bearings as pullers and presses. And then to try to falsely prove that a common tool doesn't work?! This whole situation is unreal. He goes to bike shows, hasnt he ever wondered what many lovely bearing tools are all about? Has he never seen a mechanic work? What in the actual lord farquar is going on here. It's like an ortho surgeon arguing over what bone is the femur and what is the tibia. Fook me.
Thank you. What is more astonishing to me is the number of people who A) haven’t watched this.
B) Don’t want to know.
C) even after watching it defend his actions?
🤷🏻♂️
This is quite funny and yes, I do like Hambini. Using a punch and hammer to remove a bearing is probably acceptable as you demonstrated but it is not the ideal method. Bearing pullers/presses have been around for eons (or years).
Indeed. 👍🏻
I have a compromise for both of you guys: put the bearing puller in. Then turn the thing around and smash the bearing out using a rod smashing the engaged puller claws.
OK, I've watched this whole saga from start to finish. It's hilarious. I have no idea why this has only just popped up in my feed, but here goes nothing.
So, some commentary.
5:22 The washer is a very good idea. I don't know why you weren't doing something similar beforehand given that you're all over other people for "best practices".
6:29 - "I don't know why it was taking so many hits" - because Hambini was hitting very gently, despite using a comedy-sized hammer, rather than just twatting at it blindly. Despite what you seem to think, one can hit gently with a big hammer. In any case, hitting gently is what people with a modicum of mechanical aptitude and sympathy do. I'd actually say he was going a bit fast, but there you go.
8:21 - You're hitting too hard, using a goddamn bolt instead of a 2 euro punch and a hard faced hammer rather than a dead blow. This is how we "do it properly" is it? I don't care about the punch, in the same way that I don't care about the size of hambini's hammer, but I do care about how hard you're hitting. Also, you should always do the easy one first, because it gives you a significantly better angle for attacking the difficult one. So that's another way of doing it wrong. And if you managed to push out the easy bearing in 3 hits, either the bearing fit was sloppy to start with (is this why you state the hub isn't going into anyone's bike?), or you're hitting too hard and you've now quite likely done the thing you were saying Hambini was going to do; i.e bolloxed the bore.
For the rest of it, meh. Hambini behaves like a twat from time to time, he makes a career of it, and isn't good about being criticised - yeah, there was a lot wrong with his video. Bearing pullers are great, and not even overly expensive if they don't come from park tools, but not everyone has a set.
Did we ever get any measurements from your comedy bearing inspection video?
Hi,
Your comment feels a little disingenuous but I appreciate your attempt to be unbiased. Although I disagree with the accuracy of some of your observations.
Let’s try to answer All your points.
I never damaged a hub with my puller so there was no need to get a washer before. (Necessity being the mother of all invention.) But yes, it reduces any potential risks further so I followed the advice of my viewers. I like this example because it shows a difference between Hambini and I. Someone makes constructive criticism of me and I follow the good advice and improve my system. Hambini when criticised argues the point even when he is clearly wrong and doesn’t improve anything. 🙂
On how hard he is hitting, we will have to disagree here. Honestly I don’t know how you could possibly believe he isn’t hitting hard with the sound and vibration coming from each of his hits? Yes you can hit softly with a big hammer, but he is clearly not. I explained that in great detail. Perhaps you were watching with the sound off and didn’t hear the evidence?
I don’t need to buy a €2 punch. I don’t need any large punches for the jobs I do and I don’t use them to dismount bearings. I have better tools. So I will keep the €2. 😁
I already explained why I did the harder bearing first. Please listen more carefully. 😘
As for 3 hits, no that’s normal when you have experience and skill. I checked other videos of bike mechanics (including the hope video I showed) and 3 hits is the norm.
“Meh” does that refer to Hambini lying to his audience and making up information? 😉
All the best and safe riding. 🙂👍🏻
@@reginaldscot165 Nice passive-aggressive start. Appreciated.
For 3 hits being normal, sorry, but that's bollocks. In my day job as a mechanic on big machines (ski lifts, as it happens) I was removing 10 to 20 bearings a day, over a 10 year period. Anything from 608s up to 6313s on a daily basis, and sometimes really big stuff (we're talking bearings over a metre in diameter). Apart from the really big boys, or anything mounted press fit on the shaft rather than mounted press fit in the bore, no pullers used, ever. Didn't even have a set in the workshop. Time, as they say, is money, and by the time you've set up the puller, I've already done both bearings on this jockey wheel and I'm onto cutting the tyre off. At this point, I have to admit to having been a bit cheeky with you, most of the bigger bearings were knocked out with a bit of threaded rod rather than a punch :) But like I said, don't care about the punch.
Here's the thing, though. If you could knock out any bearing, literally from 608 skate bearing size and up, with less than about 15-20 hits, either you were going too hard, or the bore was wallered out. 7-10 hits, and it's loctite-time, 5-8, and depending on what you're working on, you might centre punch the bore to get another few cycles out of the part (a chairlift guide wheel is somewhere around a thousand euros a pop, sleeving the bore is about 300 euros and a week's wait to get the part back). 3 hits, though? That's a bearing you can pull out by hand. The part's junk (or maybe the bearing was supposed to be a press fit on the shaft, and the shaft is junk, that happens too). In the case of a bicycle (or other) wheel where the shaft is stationary, it is imperative that the outer bearing ring is an interference fit with the hub, and 3 taps with a punch is not how an interference fit comes out.
I fought dozens of battles with high performers in IT projects over the last 30 years. They are really important and without them many projects wouldn't exist at all. But they don't have a direct link to reality😁. They can't admit that their genius might be wrong when it comes to daily business. And this habitus I do see in Hambinis reactions. How dare this bicycle mechanic?
If I am honest with myself I have the same bad qualities… however, in this instance I happen to be correct. 😁
Thanks for your comment. 🙏🏻
Hi Reg,
your explanation is even more convincing than in your first video. I fear you will get an even harsher and bolder response from Hambini (it's a real pity that it seems to be against his pride to admit an error on his side), but I would leave it at that and in no case I would fuel the emotional warfare. You will never convince him or his unconditional followers.
But his strategy could backfire. His manipulations and shortcuts were very easy to detect and such a thing harms his credibility in general. A honest technician would never do this. So I ask myself, how often does he use such methods in his other videos? And some of his videos are just based on websites and pictures, and this is not a sound base for a valid judgement, they are simple marketing for Hambini himself.
Just go on with your fact based work and leave the warfare to others.
Great comment. I do start to notice more issues with his other videos now…
Experience with Hambini, trying to raise engineering issues in his comment session he does tend to go passive aggressive. He doesn't seem that fluent on the engineering side. On the other hand, tapping a bearing out, even from a light aluminum part like the hub, seems reasonable if you're going to throw the bearings away. Even if there is slight distortion of the hub, the outer race is far stiffer than the aly. It's hard to see that concentricity or preload would be significantly affected (with new bearings) . measurement of an abused hub and an fea of bearing/ hub assembly would be enlightening. ps. still after some of hambini's very careless attacks on individuals and others it's somewhat satisfying to see him on the defensive.
It’s more the damage that could be caused if you use poor technique or worse miss with the hammer 🔨 🫣
Of course a 5 year old French kid is going to need to hit it loads of times 😂
That he did. 🙂
The sound check was especially funny. He must have (finally) learned because in his latest video he's pressing the bearings out instead of using a hammer.
Fantastic 👍🏻
WELL YOU DID PROVE HIM WRONG WITH EVIDENCE ,and provided humorous entertaining exserts to boot WELL DONE :)
I’m very glad you liked it! Yes I tried to prove what I was saying. Thank you for your supportive comments. All the best! 🙏🏻
I think removing a recently fitted bearing like the one in your demo will be easier than a used bearing.
I think you would be correct on that. 👍🏻
All the more reason not to use a hammer and instead use a puller. 😉
Seems like splitting hairs by both parties. Both methods seem to work well enough with care. Both seem to carry risks and the skill of the operator makes it successful.
I don't understand the point of this video. Leave it and find your own path please.
If you don’t understand how can you give orders of how I should act? Seems illogical. 🤔
There you go again...
