I had all this BS with the bike shop and wheels Manufacturing when I bought one of their PF30a centre threaded BBs. It was loose in the frame and clearly undersized coming in at 45.92mm. Wheels fobbed me off with the BS that frames are all over the place as if that was an excuse for them turning out BBs that were out of spec. Their next one was to tell me that the cups needed to be greased and that the thread centre tube was to be tightened up to clamp the bb in place across the shell. This is of course BS because a pressfit should be carrying the load by radial interference fit and should be fitted with compound between the alu BB and carbon frame (I know this because I have several contacts at Henkel through my job and have dealt with them in various design queries, and they know what they’re on about). Wheels continued their nonsense but wouldn’t accept my push back even though I’ve spent nearly 20yrs in engine design and know a thing or two about fine tolerances, such as crank bearings. Anyhow Hambini sent me a gauge to check the BB bore on the frame and was just in spec, so wheels got their scrap aluminium BB sent back to them and I bought a Hambini BB instead in Sept.2021 - fit and forget. The simple fact is consumers shouldn’t be having these arguments with component suppliers; and we shouldn’t have to wheel out the technical explanations to prove the issue. It’s fine if you can do that but many people can’t and they’re getting rinsed by customer service bull shitters and companies that know full well their products are crap.

If he published negative results, he’d risk losing income-naturally, that would make anyone favor certain brands. *Cough cough Silca* Yet, people always refer to him as the only independent tester out there.

And then it’s passed on to the designers and engineers along with a budget that they have to live with to make it a viable product for retail sale. In most cases the result is shit and the customer service who are in the trenches are left to fend for themselves with just their dicks in their hands, because the other individuals in the chain of responsibility either don’t care (because they’ve done their job) or they’ve been thrown onto other tasks.

These are my favourite Hambini features: "the manufacturing is crap and is done by clowns AND this is how I fixed it". Question for the preload - would it be possible to add the washer on the other side? I think I did something like that with a CX bike that I originally had as 2x in front. There was not enough clearance with my preferred front derailleur (FSA energy, wide range) on the inside. So on the crankset I put the wave washer on the non-drive side. Not sure if this was best and probably could have used spacers instead (have a very good set of many different thicknesses!), but it's currently ok. And better than the usual mess with my other SRAM cranks where adjusting spacing/preload is much more complicated because of their "we only adjust on one side" system. EDIT - ah, saw that the preload question has been answered already. Thanks again! And from all these videos what I've learned is stay away from 30 mm cranks like the plague.
Thnaks for the video. One question remains from my side: What exactely is the (engineering) benefit of the preload washer - compared to the screwed preload of shimano? Shimano doesn't use any preload washers on their HT-cranks. It also looks for me as if these stepped axles are ay more complicated to manufacture, than a straight hollow tube with a threaded end …
Hey, the jumpsuit is back!!!! Bravo! "Bicycle product engineer"? What is that? Someone who flunked out of engineering school so they figured they could BS it in the bike biz? Or an ex-cop who couldn't be bothered to read the book?
I haven’t had this issue with my M30 Infocrank and have had a few (replaced due to electrical/power meter issues). Have swapped them between two bikes and no creaks or any issues. Nothing to complain about. I’ll pull the crank out and check for the wear and let you know.
I have one with the 24mm axle and use it with your racing bb. I have ordered two of their new IC2 as well, which have been delayed because the company they hired didn't meet their specification (multiple times). Still waiting on those IC2's. The powermeter is really really nice, except it doesn't got Bluetooth.. which the new will have.
Meanwhile I am sitting on a bike with cheap Dura Ace BSA68 BB. Got no time for this shit, creaking, worn crank axle, worn bb shell, misalign during installation, not easy to install, need a very good tolerance of bb shell, etc.
@rollinrat4850 You said, _"If you need to use a hammer to tap the crank spindle through the cups, you have an issue. The two threads are not concentric and or the faces are not square and parallel"_ I don't mean to argue with you but it's the threads that establish the orientation of the bearings, and not the frame's BB face, right? Those threads fit very tightly and there's no way a mis-aligned face will ever alter the bearing's orientation. So the two threads have to be machined concentrically in order for those hollow tech bearings to be aligned such that there's no need to hammer the shaft into the other bearing. That's why those cartridge-type BBs were better IMHO because you have one thread that's metal (on the cartridge itself) and the other one is a non-metallic material of some kind--it will allow for a certain amount of inaccurate machining of those those BB threads. I'm dealing with this very situation on my new Surly frame right now.
@rollinrat4850, well, well, look at what RUclips just included in my recommended videos today: *_"It's on the Inside That Counts | Tech Tuesday _**_#158_**_"_* This is 4-years old now and is somewhat applicable to our discussion. You can't post links in YT comments but the title is okay I believe. My new Surly frameset that I bought has those BB threads off kilter. I ran the proper threading taps to chase the threads and then tried assembling the bearing cups and shaft--the bearing cups were not aligned. I wasn't going to pound the shaft in with a hammer so I gave up for the time being (this was last summer at a community bike shop). Surly sells this frame in a complete bike assembly (the Preamble) and uses square-taper cartridge-type BBs. They work fine. I've seen this assembled bike in my LBS. I'm going to try chasing the threads again to see if that helps but if the hollow shaft will not slip in easily on the other side, I'll have to go to a cartridge BB. The threads are what align the bearing cups, and no amount of face machining will change that. Machining those faces only eliminates any gaps that might appear and possibly allow for moisture to seep in (I know it'll get in anyways but you do what you can to minimize it). And thanks to the Great Hambini, I would've never known that these manufacturers will produce the kind of "shite" quality that they do.
@rollinrat4850, yeah, that frameset is not returnable because it was on sale last year. And as I said earlier, it'll probably work fine with a square-taper cartridge BB so they (Surly) will probably not accept responsibility. The only thing I can think of is to heavily "chase" both BB threads to see if that allows for a better alignment in the bearing cups. If that doesn't work, then it's goodbye hollow tech BB and hello cartridge BB. I'll let you know how that works out when I get around to it again.
Wow, talk about perfect timing. I bought a Scott Addict Gravel 30. 191.5 miles later, on light gravel, with a mixture of tarmac to get to the gravel sections, all dry conditions I might add. Horrendous creaking and grating from the crank. Slid the Praxis crank out and found that while the driveside bearing is butterly smooth, the non drive side bearing is as coarse as hell. Ennduro bearings. Is this a bearing or design fault?Bought the bike new i June 2023. Ride mainly road, but having come from MTB, I do like a bit of non tarmac fun. Who should I chase for the problem? Scott, bearing supplier or shop where I bought the bike.
What's really strange about this design is that the wave washer looks to be loading the whole face of the bearing rather than just the inner race that spins with the crank and spacer, unless the spacer is shaped to transfer the load only to the inner race. It looks like a rectangular cross section ring, but this could be subtle. Tightening the tolerances a little and adding a Belville washer instead of the wave washer might be a fix that gets more of the bearing on the bearing seat on the axle and will accommodate wear without play instantly appearing, but I don't know whether these washers are available off the shelf to do this - getting custom parts made would be very expensive per crankset unless you were doing thousands of them though.
The spacer has a lip, so the outer race is cleared, which you can see in the video. Praxis wouldn't mess something simple like that up. I don't know if they make bellvilles with low force ratings for this application. Maybe higher would be OK though..
@@jaro6985 A very thin belville washer will have low spring force as well as taking up minimal space along the axle, so it could meet the requirements for this perfectly.
waiting for the zero friction reaming , im a waxer and will always be because dry chain lubes are all dogshit and wet lubes attract too much dust so the wax is turning out to be the perfect middleground (i make my own with parrafin candles and shell tellus s2m 32 hydraulic oil that we use as lathe gear head oil and way oil )
How is there wear on the NDS bearing seat if the bearing is pinned against the axle lip by the L/H crank arm? How does a short bearing seat on the other end effect this contact? Isn't it more likely that the crank wasn't done up tight enough or the original ID tolerance of the NDS axle and bearing was less than ideal?
@@HambiniI'm asking you because it's your explanation. How can there be wear marks for the pinned bearing and no marks for the partially seated floating bearing?
*RIP Verve Cycling Infocrank™* For them to totally recognize the problem would mean the kind of recall that would probably bankrupt them. They were too cheap to take care of the problem on a per customer basis. They were betting that no one would make the situation known by the public. This morning, they woke up and realized that they've lost their bet in the worst possible way.
The market is done, anyways. We have cheap spindle based power meter, the pedal based (can't wait for a video) and the random number generator by Shimano. Stages died for a reason and SRM seems to downscale/hyperfocus on track and its niche.
@@RolandRides The Chinese brand Magene and others like it will take the low-mid end of the market and once its done, they'll go for the upper end. Just like it will be the case the case with oem groupsets. The current market leaders better buckle up because the ride will be rough in the next decades. Shimano, SRAM, Garmin, might go the same path as Campagnolo at some point.
Great stuff as usual. No idea oni the technical details really, but surely when praxis supply this to Infocrank (i assume), they should start making the bearing seat a bit longer. Is it just as simple as them removing less material when they CNC the material? And i think you said the problem is only on the power meter version not the version without sold direct by Praxis. Its not even engineering, it looks like just dodgy math!
@@Hambini I’m basically also a 5-year old at heart and humour. Example, remember the little miss muffet limerick! On serious note truly terrible customer service!
@@Hambini Karen says: Either they f**ked up in design, production or QC. My guess: The manufacturer had the lathe run a little bit to long, so the shoulder on the DS got too short. Small errors cause massive problems …
Even a luddite non-engineer, product designer, like myself, can see at first glance that it's too small. What were they thinking? Clearly they weren't. Why not simply make it bigger than the minimum requirement, allowing for all variances in preload and temperature? Having one bearing seated and the other floating seems like a pretty shit arrangement - but hey what do I know. Surely both bearings properly seated would be stiffer and more desirable?
One 6806 is rated for 340kg static load, are you really heavier than that? BB bearings fail due to contamination/corrosion most of the time, assuming proper alignment/design.
Love your knowledge and input into cycling knowledge. I have come to notice that you obviously suffer from OCD. You ask why I would say that. Look at the background of your workshop. The shovels are arranged precisely spaced against the back wall. They are so evenly spaced I reckoned you measured the space between each shovel o they didn't look uneven on your video.
Hambini!…an unrelated post to your video…I’m having a dispute with a riding mate ..he is bent on having every bit of aero equipment and kit and I say the it’s largely a waste of money, that aero advantages in equipment are really only meaningful for the very elite or Pro Tour riders where the differences in talent and ability in relatively small Have you ever produced a video on this subject?..if not could you?
Do the maths, you´re correct. To us mortals, doing around 30km/h, the difference between an aero bike and your old rig is about 10W. Corresponds to about 1 cog in the cassette. Totally different if you average 45km/h... Rgr
"Jimmy, I need to let you know about something." "Yes, what is it?" "The crank that your responsible was recently reviewed by Hambini on RUclips." "Oh. Dear God." "Am I f'ed?" "100% you are."
@Hambini if you have option now to build a bike for around 2000Pounds to 2500Pounds for more agressive cyclist / sprinter. what would you recommend wheels,brakes,frame etc ???
Can you recommend me a 170mm crankset for my new Hambini SRI bottom bracket on a 73mm wide mtb frame with boost hubs? I am ditching a creaking Hope Stainless BB with Hope Evo crankset. The spindle is most likely worn out against the steel bearings. I changed the BB bearings and it still creaks. Raceface Aeffect? Shimano XT? XTR?
sad that these companies take it against hambini to try to fix their crappy product ..... ! not clever at all for business if you ask me... but what do i know ?
On my praxis works BBs the NDS bearing has a little sleeve insert reducing the ID and accommodating the step down of the shaft. Does the infocrank implementation have this?
If praxis makes the crank arms, Who did the spindles? So the powermeter is crankbased or spindle based? Seeing where the error was the bearing seat? Or I’m wrong here? 😅
The parent company of Praxis made the cranks, the spindles, the chainrings and the bottom brackets. Verve designed and made the power module. And it was done nearly 10 years ago.
Easy fix for that infocrap, Bin the wave washer and seal....And sod the dust ingress. 🙂 He can change the shagged bearings more often, or otherwise BUY A SHIMANO POWERMETER!!! Lol
Power is truth. It is the best way to monitor your physical condition on a bike. If you don’t care about that, then there is no value for you to measure your power.
I know significantly less than a 5yo but could the preload be on the inside. The full width of the bearing onto the landing and maybe a sleeve from side to side so that both bearings are loaded.
@@sylvainmichaud2262 Statement by support: "We see very few of these (a few more on Classics, very few on M30’s) but it seems that pedalling style (with some twist) weakens the metal over time, so then it eventually breaks ‘suddenly'. The metal testing is done straight down the edges and the cranks will last a lifetime in that direction, however, with a twisting style introduced, their life is more limited. The couple of riders who have broken M30’s and had them replaced, have broken the next cranks too, while at the same time we have had Olympic Team riders ride the same cranks for many years without them breaking - so it seems there is something in the style that makes the difference. We have taken that into account in the design of IC2 and this is made in a ‘hollow' box shape design, in order to be stronger in the twisting directions, as well as the normal pedalling direction. We believe this will give the IC2 a longer life for all cyclists, no matter their style."
What i dont get....why would some1 pay that much for a powermeter crank that is so fcn heavy....and then pay even more $$$ to get that shite fixed? Just get some assiomas and be happy
The part where this can't have every worked is a bit confusing. This should have been an RTM NFG. Does their recommended bottom bracket solve the issue? Double checked their web site and they claim perfect fitment with a Shimano bottom bracket.
Thats the infocrank IC2, not this one. Their newer crank uses 24mm steel spindle, probably because their old one was crap, and shimano's patent might have ran out?
Yes, though you need to add more shims over time to take up play introduced by bearing wear, or regularly replace the bearings. That's why they use a wave washer (essentially a form or spring) so it automatically adjusts.
What I don't understand is why people continue to buy expensive shit like this? I have a Shimano BB M815 on all my mtbs and it works perfectly fine, with a second hand Shimano crankset. Did you still didn't realise that the cycling industry is lying to you? Buying second hand is much better, usually you have time to process what is good or not. Anyway bad stuff never have time to finish on the second hand market, because they are all broken before. I mostly ride stuff that have 10 to 50 years, on my mtb and road bike, I rarely have mechanical issue.
I'm not an engineer. Could you not build a shim to extend the shoulder? Something split in two, that extrudes from a bearing-sized block of metal, held together with a couple of bolts, that clamp it inside the bearing, inside the bb shell? Again I'm no engineer.
If you don't start with the usual " hello hambini fans " - I am missing the first sentence (turning the volume down at the intro) and that is bothering me. So. Please keep the customary thing CONSISTENT. Engineering is top notch but ... I am not here only for the engineering.
I wonder why people send it for Hambini to fix instead of just buying another crankset. I mean: isn't he busy with other stuff? Like going to Kindergarten?
@@ScrubsIsee, exactly right! If it wasn't for the Great Hambini, when I started following him about four years ago, I would've never know about the shoddy manufacturing practises of some of these high-priced bikes. I hope he never stops exposing them.

Shimano doesn't use any preload washers on their HT-cranks. It also looks for me as if these stepped axles are ay more complicated to manufacture, than a straight hollow tube with a threaded end …
It's a lot cheaper to stick a wave washer on the end than a thread and spline

epic! 20:09 shades of times past from a certain bicycling publication
Hey, the jumpsuit is back!!!! Bravo! "Bicycle product engineer"? What is that? Someone who flunked out of engineering school so they figured they could BS it in the bike biz? Or an ex-cop who couldn't be bothered to read the book?
I haven’t had this issue with my M30 Infocrank and have had a few (replaced due to electrical/power meter issues). Have swapped them between two bikes and no creaks or any issues. Nothing to complain about. I’ll pull the crank out and check for the wear and let you know.
Am running two BSA frames, so Praxis M30 BSA BB. So maybe BSA is less prone? Shouldn’t be from what you’re describing! 😊
I have one with the 24mm axle and use it with your racing bb.
I have ordered two of their new IC2 as well, which have been delayed because the company they hired didn't meet their specification (multiple times). Still waiting on those IC2's.
The powermeter is really really nice, except it doesn't got Bluetooth.. which the new will have.
Excellent video, thank you.
Meanwhile I am sitting on a bike with cheap Dura Ace BSA68 BB. Got no time for this shit, creaking, worn crank axle, worn bb shell, misalign during installation, not easy to install, need a very good tolerance of bb shell, etc.
Nothing like the Cartridge Bottom Brackets for longevity and ease of replacement.
@rollinrat4850 You said, _"If you need to use a hammer to tap the crank spindle through the cups, you have an issue. The two threads are not concentric and or the faces are not square and parallel"_ I don't mean to argue with you but it's the threads that establish the orientation of the bearings, and not the frame's BB face, right? Those threads fit very tightly and there's no way a mis-aligned face will ever alter the bearing's orientation. So the two threads have to be machined concentrically in order for those hollow tech bearings to be aligned such that there's no need to hammer the shaft into the other bearing.
That's why those cartridge-type BBs were better IMHO because you have one thread that's metal (on the cartridge itself) and the other one is a non-metallic material of some kind--it will allow for a certain amount of inaccurate machining of those those BB threads. I'm dealing with this very situation on my new Surly frame right now.
@rollinrat4850, Holy shite! How long did it take you write all this?
@rollinrat4850, well, well, look at what RUclips just included in my recommended videos today: *_"It's on the Inside That Counts | Tech Tuesday _**_#158_**_"_* This is 4-years old now and is somewhat applicable to our discussion. You can't post links in YT comments but the title is okay I believe.
My new Surly frameset that I bought has those BB threads off kilter. I ran the proper threading taps to chase the threads and then tried assembling the bearing cups and shaft--the bearing cups were not aligned. I wasn't going to pound the shaft in with a hammer so I gave up for the time being (this was last summer at a community bike shop).
Surly sells this frame in a complete bike assembly (the Preamble) and uses square-taper cartridge-type BBs. They work fine. I've seen this assembled bike in my LBS.
I'm going to try chasing the threads again to see if that helps but if the hollow shaft will not slip in easily on the other side, I'll have to go to a cartridge BB. The threads are what align the bearing cups, and no amount of face machining will change that. Machining those faces only eliminates any gaps that might appear and possibly allow for moisture to seep in (I know it'll get in anyways but you do what you can to minimize it).
And thanks to the Great Hambini, I would've never known that these manufacturers will produce the kind of "shite" quality that they do.
@rollinrat4850, yeah, that frameset is not returnable because it was on sale last year. And as I said earlier, it'll probably work fine with a square-taper cartridge BB so they (Surly) will probably not accept responsibility.
The only thing I can think of is to heavily "chase" both BB threads to see if that allows for a better alignment in the bearing cups. If that doesn't work, then it's goodbye hollow tech BB and hello cartridge BB. I'll let you know how that works out when I get around to it again.
Wow, talk about perfect timing. I bought a Scott Addict Gravel 30. 191.5 miles later, on light gravel, with a mixture of tarmac to get to the gravel sections, all dry conditions I might add.
Horrendous creaking and grating from the crank. Slid the Praxis crank out and found that while the driveside bearing is butterly smooth, the non drive side bearing is as coarse as hell. Ennduro bearings. Is this a bearing or design fault?Bought the bike new i June 2023. Ride mainly road, but having come from MTB, I do like a bit of non tarmac fun. Who should I chase for the problem? Scott, bearing supplier or shop where I bought the bike.
I remember these cranks from Francis Cade's RUclips channel from a few years back.
What's really strange about this design is that the wave washer looks to be loading the whole face of the bearing rather than just the inner race that spins with the crank and spacer, unless the spacer is shaped to transfer the load only to the inner race. It looks like a rectangular cross section ring, but this could be subtle. Tightening the tolerances a little and adding a Belville washer instead of the wave washer might be a fix that gets more of the bearing on the bearing seat on the axle and will accommodate wear without play instantly appearing, but I don't know whether these washers are available off the shelf to do this - getting custom parts made would be very expensive per crankset unless you were doing thousands of them though.
The spacer has a lip, so the outer race is cleared, which you can see in the video. Praxis wouldn't mess something simple like that up.
I don't know if they make bellvilles with low force ratings for this application. Maybe higher would be OK though..
@@jaro6985 A very thin belville washer will have low spring force as well as taking up minimal space along the axle, so it could meet the requirements for this perfectly.
waiting for the zero friction reaming , im a waxer and will always be because dry chain lubes are all dogshit and wet lubes attract too much dust so the wax is turning out to be the perfect middleground (i make my own with parrafin candles and shell tellus s2m 32 hydraulic oil that we use as lathe gear head oil and way oil )
How is there wear on the NDS bearing seat if the bearing is pinned against the axle lip by the L/H crank arm?
How does a short bearing seat on the other end effect this contact?
Isn't it more likely that the crank wasn't done up tight enough or the original ID tolerance of the NDS axle and bearing was less than ideal?
Because the drive side bearing can rock and seesaw on the edge of the seat.
@@Jonbspok, if it's rocking and "seesawing" (whatever that is supposed to mean) then why are there no wear marks..?
That makes no sense.. 🤷♂️
Ask karen in customer service and see what she comes back with!
@@HambiniI'm asking you because it's your explanation.
How can there be wear marks for the pinned bearing and no marks for the partially seated floating bearing?
@@drayzen9678 I have no idea. I thought the feedback from infocrap would lead me in a general direction of fault finding but it didn't.
*RIP Verve Cycling Infocrank™*
For them to totally recognize the problem would mean the kind of recall that would probably bankrupt them.
They were too cheap to take care of the problem on a per customer basis.
They were betting that no one would make the situation known by the public.
This morning, they woke up and realized that they've lost their bet in the worst possible way.
The market is done, anyways. We have cheap spindle based power meter, the pedal based (can't wait for a video) and the random number generator by Shimano. Stages died for a reason and SRM seems to downscale/hyperfocus on track and its niche.
@@RolandRides
The Chinese brand Magene and others like it will take the low-mid end of the market and once its done, they'll go for the upper end. Just like it will be the case the case with oem groupsets. The current market leaders better buckle up because the ride will be rough in the next decades. Shimano, SRAM, Garmin, might go the same path as Campagnolo at some point.
its fascinating how every single bad product has a name that rhymes with crap or shite :)
Just curious, did you consider putting the wave washer on the other side and place of the spacer that you added?
Oh boy! Verve has the Nerve?
Shimano crank assembly is still the ducks guts
Great stuff as usual. No idea oni the technical details really, but surely when praxis supply this to Infocrank (i assume), they should start making the bearing seat a bit longer. Is it just as simple as them removing less material when they CNC the material? And i think you said the problem is only on the power meter version not the version without sold direct by Praxis. Its not even engineering, it looks like just dodgy math!
I've had their m30 system and their 24mm Shimano. I wouldn't touch their M30 with a barge pole. Especially in BSA threaded set up. Horrible.
That was their advice?! Dire.
What d'ya expect from a receptionist?
So, this particular ’slack fit’ is a ‘ball ache’ that results in a ‘loss of stiffness’ - perfect phrasing 😂

@@Hambini I’m basically also a 5-year old at heart and humour. Example, remember the little miss muffet limerick! On serious note truly terrible customer service!
Always interesting!!!
The bearing landing is too small. How is this not plainly obvious during design and manufacturing ?
ask karen
@@Hambini Karen says: Either they f**ked up in design, production or QC. My guess: The manufacturer had the lathe run a little bit to long, so the shoulder on the DS got too short. Small errors cause massive problems …
sounds like a typical karen
Even a luddite non-engineer, product designer, like myself, can see at first glance that it's too small. What were they thinking? Clearly they weren't. Why not simply make it bigger than the minimum requirement, allowing for all variances in preload and temperature? Having one bearing seated and the other floating seems like a pretty shit arrangement - but hey what do I know. Surely both bearings properly seated would be stiffer and more desirable?
Could you have made a shim to extend the landing and bond to the crank, or is that just impractical?
Two Hambini videos in a week!?
Some kind of inflation?? Rgr
Your pen is working
JFC. My old FSA threaded 2 cup triple crank has no such issues.
I'm as pumped for that ZeroFrictionCycling video as I was for deadpool 3.
BB,s were never a problem using 1/4" balls, using bearings more suited to an electric fan, will always fail early.
One 6806 is rated for 340kg static load, are you really heavier than that?
BB bearings fail due to contamination/corrosion most of the time, assuming proper alignment/design.
How is it over 250g heavier than 105 😂
Love your knowledge and input into cycling knowledge. I have come to notice that you obviously suffer from OCD. You ask why I would say that. Look at the background of your workshop. The shovels are arranged precisely spaced against the back wall. They are so evenly spaced I reckoned you measured the space between each shovel o they didn't look uneven on your video.
Your shovels need to be in working order when you shovel as much excrement as Hambini sees. Cycling industry... Shakes head.
Not convinced!! The princess blanket can be seen as a bit dirty now and again.. Wait.. Princess Blanket??? Rgr
Hambini!…an unrelated post to your video…I’m having a dispute with a riding mate ..he is bent on having every bit of aero equipment and kit and I say the it’s largely a waste of money, that aero advantages in equipment are really only meaningful for the very elite or Pro Tour riders where the differences in talent and ability in relatively small
Have you ever produced a video on this subject?..if not could you?
Do the maths, you´re correct. To us mortals, doing around 30km/h, the difference between an aero bike and your old rig is about 10W. Corresponds to about 1 cog in the cassette. Totally different if you average 45km/h... Rgr

@@Hambini what buy whole bike from them ?
Is it possible to install the w-washer on the NDS, like in FSA systems?
But why would they machine the axle part to be too short for the bearing + wave washer? Are they unable to add up simple numbers?
Why isn’t there visible wear on the drive side bearing seat? If the bearing is half off and the whole thing is rocking?
It doesn´t rock enough in that end. Rgr
Someone thought GXP is a good construction 🤷♂. They'll better try building ventilators
Can you recommend me a 170mm crankset for my new Hambini SRI bottom bracket on a 73mm wide mtb frame with boost hubs? I am ditching a creaking Hope Stainless BB with Hope Evo crankset. The spindle is most likely worn out against the steel bearings. I changed the BB bearings and it still creaks. Raceface Aeffect? Shimano XT? XTR?
sad that these companies take it against hambini to try to fix their crappy product ..... ! not clever at all for business if you ask me... but what do i know ?
On my praxis works BBs the NDS bearing has a little sleeve insert reducing the ID and accommodating the step down of the shaft. Does the infocrank implementation have this?
Yes, no problem on the non drive side, it's only the drive side
Hambiniiiii
Great video.
If praxis makes the crank arms, Who did the spindles? So the powermeter is crankbased or spindle based? Seeing where the error was the bearing seat? Or I’m wrong here? 😅
The parent company of Praxis made the cranks, the spindles, the chainrings and the bottom brackets. Verve designed and made the power module. And it was done nearly 10 years ago.
What about absolute black on your scale?
Needs a different scale?? Rgr
That's in... Ahh yeh!
Easy fix for that infocrap, Bin the wave washer and seal....And sod the dust ingress. 🙂 He can change the shagged bearings more often, or otherwise BUY A SHIMANO POWERMETER!!! Lol

What's this obsession with power meters for us mere mortals?
@@MrJx4000 Same as fitness apps, step counters and cars that will do 160mph in a pot hole/legal ridden infrastructure.
Power is truth. It is the best way to monitor your physical condition on a bike. If you don’t care about that, then there is no value for you to measure your power.
"Gas-Lighting" Customers is the 'New' Fashion, they learned it from "Human Resources", because it is Cheaper for the Company.
I know significantly less than a 5yo but could the preload be on the inside. The full width of the bearing onto the landing and maybe a sleeve from side to side so that both bearings are loaded.
that's how I've done it but the praxis manual which is on their website shows otherwise.

@@sylvainmichaud2262 Statement by support: "We see very few of these (a few more on Classics, very few on M30’s) but it seems that pedalling style (with some twist) weakens the metal over time, so then it eventually breaks ‘suddenly'. The metal testing is done straight down the edges and the cranks will last a lifetime in that direction, however, with a twisting style introduced, their life is more limited. The couple of riders who have broken M30’s and had them replaced, have broken the next cranks too, while at the same time we have had Olympic Team riders ride the same cranks for many years without them breaking - so it seems there is something in the style that makes the difference.
We have taken that into account in the design of IC2 and this is made in a ‘hollow' box shape design, in order to be stronger in the twisting directions, as well as the normal pedalling direction. We believe this will give the IC2 a longer life for all cyclists, no matter their style."
What i dont get....why would some1 pay that much for a powermeter crank that is so fcn heavy....and then pay even more $$$ to get that shite fixed?
Just get some assiomas and be happy
Info crank's electronics are good, they made the mistake of teaming up with Praxis.
I'm sure infocrank customer service she meant to say chef/engineer. Makes a decent nuked lasagne as each layer is measured the same way.
What is this....... No hello! Ooo.. good.....
The part where this can't have every worked is a bit confusing. This should have been an RTM NFG. Does their recommended bottom bracket solve the issue? Double checked their web site and they claim perfect fitment with a Shimano bottom bracket.
Thats the infocrank IC2, not this one. Their newer crank uses 24mm steel spindle, probably because their old one was crap, and shimano's patent might have ran out?
what does "fobbed off" mean?
Can the average punter just buy a stack of bearing shim washers and use those to space it to the correct tolerance?
Yes, though you need to add more shims over time to take up play introduced by bearing wear, or regularly replace the bearings.
That's why they use a wave washer (essentially a form or spring) so it automatically adjusts.

What I don't understand is why people continue to buy expensive shit like this?
I have a Shimano BB M815 on all my mtbs and it works perfectly fine, with a second hand Shimano crankset.
Did you still didn't realise that the cycling industry is lying to you?
Buying second hand is much better, usually you have time to process what is good or not. Anyway bad stuff never have time to finish on the second hand market, because they are all broken before.
I mostly ride stuff that have 10 to 50 years, on my mtb and road bike, I rarely have mechanical issue.
I have found from experience a bike brand that manages to be Olympic level of shit quality and shit customer service is Calibre Bikes.
I'm not an engineer. Could you not build a shim to extend the shoulder? Something split in two, that extrudes from a bearing-sized block of metal, held together with a couple of bolts, that clamp it inside the bearing, inside the bb shell? Again I'm no engineer.
it would be ~0.05mm thick, you'll have more luck with single ply toilet paper
You're right--you're definitely not an engineer!
If you don't start with the usual " hello hambini fans " - I am missing the first sentence (turning the volume down at the intro) and that is bothering me. So. Please keep the customary thing CONSISTENT. Engineering is top notch but ... I am not here only for the engineering.
I wonder why people send it for Hambini to fix instead of just buying another crankset.
