How Repairable Is A Carbon Mountain Bike?
HTML-код
- Опубликовано: 24 июл 2024
- We often hear people say that they buy aluminium frames instead of carbon because they are scared of breaking them, but with the repairability of carbon compared to aluminium frames, there's an argument that carbon could be the better option long term! Anna is at the Bristol Bike Repairs shop to run through repairing her damaged MTB frame and get an in-depth look at the carbon fibre repair process needed to get her bike back out on the trails!

Very interesting but would have liked to have seen the finished result.
Sorry guys, it had to cure for 24hrs and then get sanded the next day! It’s totally smooth and seemless now though. You can catch a glimpse of it in my next video where I re-spray it myself at home… sorry for the cliffhanger 😂
I work in a bike shop and have sent lots of carbon frames to get fixed and after piant they look band new
@@AnnaOnTheBike Thanks Anna!
Typical gmbn
That Gritzl frame must be less then year old. Why did you go for carbon repair instead of using the Canyon's crash replacement programme, Anna? As stated in the video, you are loosing warranty when doing unauthorized carbon repairs.
Definitely would like to see the results and maybe the story of how you caused the damage.
This bike will feature in a future video, so keep your eyes peeled! 👀
My cracked frame been repaired once a couple years ago , repaired part still stiff and durable, I'm using my bike as usual with no limits. Good job
Thanks for sharing! It's great to hear that so many people have had really positive experiences with carbon repairs. 👍
Personally, I avoid carbon frames 10% because every time a sharp rock bang hard into my frame I imagine it cracking oopen a carbon one, and 90% because I don't think they're worth the premium. Sure, if you're racing (and serious about it), then by all means take every advantage you can. But for hobbyist riders just looking for fun and a healthy sport, I feel like it's money thrown out of the window that could've went into better components. If money is not a problem, whatever suits you, but I think the hobby is already overly expensive to worry about grams on non-competitive riding.
I'm with you mate. I'd rather invest in top of the line suspension and brake components and feel comfortable on my aluminium frame.
Yea this is my logic to get another aluminum bike. On my first road bike I got hit about 2-3 times, my bike fell a few times as I flew off, sometimes it just fell because I didn't fully learn how to release my shoes. I also ran right into a massive ebike dude because he stopped in the middle to make a turn. There is no way a carbon would have survived all of this new york city madness.
That is great. Although you should have mentioned the cost of the repair and the accessibility because for example, I could not find any shop like this in my country.
Aluminum frame with carbon components is the way am going with my new build. I don't want "what if it cracks" at the back of my mind every time I ride. Great insight Anna. Thanks
That's an interesting approach. I'd rather take a carbon frame with alloy components any day. I've rarely seen carbon frames snap due to hard riding (without a crash) but it's not terribly uncommon with handlebars and cranks . And don't even get me started on rims. They are great until you hit a square edge. Not the level of reliability I'm looking for. Probably great for the average cross country rider but not always the best for gravity riding.
Aluminum snaps just as violently. I'm missing teeth because my norco charger snapped. I also folded my specialized p3 at the top tube and split the downtube weld. Gave myself a dirty scorpion and whiplash that time.
@@burningatthetrailhead ouch! Sounds painful. Thanks for your insight 👍🏾
Nah i would go 100% alu, or carbon frame alu components, after speaking with a lot of bike shops carbon components make no sense, just wheels...the other components usually snap...
Umm aluminium cracks *much* easier than carbon tho, and is much less repairable, so no clue what you are talking about?
This isn’t selling me on a carbon frame at all.
will there be a follow up vid showing the finished repair?
Really cool seeing how carbon is repaired to keep them going and seeing BBR at work. I want to get respray on my Stanton from them soon!
Could you do similar content for other frame materials too?
What did it cost? And what did the final fixed frame look like?
You can delaminate it without it being visible. On a mine hunting ship i was on in the navy made from glass fiber there was a regular service after x amount of years in use where there was a guy with a tiny hammer that checked every few centimeter of the ship by lightly tapping the hull with the hammer and if there was a hollow sound it was delaminated. Typically at the bottom of stairs and ladders and other areas that regularly got impacts was delaminated and needed to be repaired.
Lots of great points, does it not require a post cure bake to get the best out of the resin? Also was it electric tape used for consolidation? Wouldn't the stretch in that reduce strength and increase weight?
Could you make a video about how we could decide between similar carbon fiber bikes from different brands? My guess is they all use the carbon fibers differently (eg the direction of the carbon fiber sheets); so how can we tell which are better quality or better in some aspects than others?
I've used a variety of carbon fibre products to make a gravel bamboo bike in my garage - carbon fibre is much easier than people think, to work with. I'd certainly be happy doing carbon repair work to my own frame, however, other than the bamboo/carbon frame I ride a steel road bike, titanium fatbike and alloy full sus.... It isn't the strength that worries me - it's the cost 😜
Hello, bro! Hope u doing well.
Just got my first carbon road frame, and still insecure about the resistance of the material. So, just to gather someone else’s opinion… would go all carbon considering the material resistance?
Just had a lil crash couple days ago, but nothing too serious- a lil 8yo girl just crossed the street w her bike and caught me by surprise-, and visually, nothing seemed to happened.
I would appreciate to hear ur thoughts.
Ty for yr time!
All the best
The problem is not repairability itself, but the reliability on a crash. Even on XC level which is not hash riding, over the years I've seen several cracked carbon frames and no aluminum frame so far. The only aluminum frame I saw die was my old full suspension AL frame, which was ht by a motorcycle who skipped a stop sign and hit me by the side, destroying the rear triangle, but then again, yeah I don't see a carbon frame surviving that either, lol
It's great carbon can be repaired, but at least in my country it's not a cheap repair and due to demand can take weeks without riding, or even while you save for the repair 😅and considering cracking can happen a few times in the component's lifetime, not an easy pill to swallow for many people just to save some grams when your belly has some extra kilograms 😀
Exactly
Great reply! Outside of serious competition, it is hard to justify sacrificing any reliability for the weight and/or stiffness gains.For perspective I should add that I am an old person who just doesn’t want the bike to leave me stranded.
Aluminum frames can and do fail. Usually the failure mode is a cracked weld which cannot be reliably/safely repaired as the whole frame would need to be stripped of paint and then heat treated in an autoclave.
@@Gabesafish probably the only material that won't experience a failure point for bikes is titanium, but that is probably out of the question. Putting that aside, that does not deny the original point, aluminum is more durable than carbon, needs more stress to reach a failure point, and once reached that point is cheaper to replace and such replacement will last longer.
Maybe a really good TIG weld might last awhile if braced with an excessive amount of material or gussets.. such as sliding a tube with the I.D. that is the same as the O.D. of the parent material , over the crack or damage after it’s been welded, and then welding around both ends of the “brace”.. but even then it will likely break.
In rowing it's quite common to repair broken carbon oars and sometimes even hulls. Specially racing oars have to withstand an impressive amount of force, and if well repaired, difference (if any) is unnoticeable.
Honest guy, this repair man. He is very honest with you, Anna.
Really interesting process and techniques, always great to learn about the products and the bike industry as a whole, please also pop to Argos bikes in Bristol and see what can be done with Steel, Alloy and Ti bikes in terms of repairs and refurbishments
The point is, what makes the damage in the first place. A dropped chain, a flying pebble, or just the bike falling over most likely won't damage an aluminum frame. Yes, you can repair carbon, but aluminum or steel doesn't need repairing from small things.
Still not convinced, i'd rather have a bit heavier and long lasting frame, than being afraid that an unnoticed damage can cause my bike break in half.
All sounds decent , however the cost pay for the carbon repair, and then a re spray would total a lot? Plus time assembling your bike back together.
It depends on the crack and the paint depends on what you need, but it’s likely to be less than a new frame!
@@AnnaOnTheBike that’s possible true. Look after your bike, and your bike will look after you . Hopefully.
A mate of mine for a quote for repairing a crack in his Cannondale frame.
£800 without any paint work repairs.
Wasn’t even crash damaged either, just a crack in the yoke between the two chainstays.
No thanks!
@@stefromfortworth firstly, I’d say shop around on price, but if that’s the cost of a difficult repair, it’s still cheaper than a new frame! 🤷♀️
@@AnnaOnTheBike You could, but you’d be lucky to find more than one carbon repairer within a hundred miles of your home, so you’re kind of stuck with whatever price they ask for. And it’s still bound to be a laborious process so will be eye-wateringly expensive regardless. What was the cost of your repair, out of interest? If you did pay?
Might be cheaper than a new frame but who in the real world has £800 lying around just in case a frame breaks? Welding is a fraction of the cost and far more tried and tested than even this repairer’s methods!
Sorry but Carbon is just destined for landfill. I can understand it for racers and maybe you GMBN guys who change their bikes more often than socks…. But I want a bike that doesn’t 💩 the bed after a few rock strikes 😂
Steel or Ally all day!!
As far as wrapping with tape
I would use heat srink tape this will compress the repair much better and hopefully force the resin futher into the crack aswell
You might have come up with a great idea. I have used the heat shrink products and they work well
To water proof hotrod wiring. And it pulls down real tight conforming perfectly with the surface. However getting it in place without cutting and basically ruining its drow down capabilities and rendering it useless. May be a challenge.
@@David-qx8jm heat shrink tape is a plastic wrapping tape that you wrap on like he did with the electrical tape (electrical tape is something a home repairer does rather than a professional) and heat with a heat gun to shrink and squeeze out as much epoxy as possible to make the repair stronger. I think you are thinking of electric heat shrink tubing which is more rubbery and would be hard to put on like you said.
Yes heat shrink tape is the proper way to do it, not just electrical tape. No, not the same product as heat shrink tubing
I like this channel more than the rest of gmbn's 🙃 love ya doddy
Thanks, Patryk! Tech is always the best! 😉
I'm guessig this repair is doable for dh or enduro bikes as well, where the stress on the frame is high.
Could you do a follow-up on this video so we can see the and result please?
Hey David! This bike will feature in a coming video. Stay tuned! 👀
why would I get a frame that needs to be repaired every time it gets a little scratch
Carbon comes with a 'saw it on gcn/gmbn therefore i must keep up' price tag attached to it sadly.
Or ride both and then make blanket statements. I could blind folded (well sensibly) ride any bike and tell you if it’s carbon or aluminium every single time.
Aluminum is cheaper and recyclable . That’s my main reason for switch
Carbon is also becoming more recyclable.. slowly, but its getting there
Carbon: "chain falls off, needs repair" , Aluminium: "chain falls off, get the crowbar, we need to get the chain out" :))
It's not the snapping part that's scarry. It's the spitting your teeth out and the dentist bill after. I've snapped and folded aluminum frames, forks and cranks. I smashed out three teeth and had road rash from mouth too knees. I was wearing a helmet every time
Exactly.
Sorry not convinced, but in as much as some bike frames only come in carbon, then what choice do I have? This video does give me some confidence that for my high level of careful riding, with infrequent falls, and not bad ones, Carbon might be OK. Thanks. It is just a shame that I can’t get my frame of choice in steel, but the extra 2 lbs it would cost might still result in a weaker (albeit more compliant) frame. Least I do not need to worry about rust.
Interesting being Gmbn are there bike shops in South Africa 🇿🇦 that repairs carbon
Just wondering how much will the repairing be and is it worth it?
Finished product???
I are off my road bike and scuffed the handlebar at the plug and discovered the crack at the head tube of the frame, repaired by Magnafibre in Alva near Alloa £100
Aluminum and steel frames with carbon kit that's me.If its cracked bin it, not trusting my life on someone else's repair. Thank you-:)
Otherway around for me, Broken off headtubes of alloys and smashed downtubes. no thanks. carbon only
What! Where's the other half of the video?
I guess one question is what happens if you come to sell a frame on which has had a crack or a repair? Presume that even with a repair done, the frame would be worth significantly less, you'd have to declare it to the buyer and there is never any guarantee that the repair might last for years given that he only offers a 12 month warranty. At least with Aluminium, the frames are usually quite a bit cheaper to replace in their entirity and more easily recycled when damaged.
I have broken two aluminium frames... all my bikes are titanium now. Carbon just looks so worn after a few months....
How much would a repair like this cost?
I'm not convinced by that repair, seems like a high tech plaster/ band aid with some resin seeping into the crack, what about cracks that are deeper or almost totally cracked, why didn't we see the finished article or get a rough estimate of cost. This video leaves more questions than answers.
I'll stick with alloy frames, I've ridden frames with small dents in the downtube and toptube, couldn't do that with carbon.
I fix my 'Lumi frame w/a bottle of nail polish 😂
You can also repair alloy frames with carbon with a glass under layer
Yes like this video,
Thanks for the support! 👍
Well, why didn't they show what happened? ((
Hi! The frame had to cure for 24hrs and be sanded down the next day. Stay tuned for when this bike features in Anna's next video.
@@gmbntech tnks)
Would get the crash repair frame
On a mostly road-going MTB, carbon may be okay, but if I plan on going XC, I'll go aluminium. Also, I'm on a budget.
If you can, rent a carbon XC for XC’ing. I own one, it’s wonderful!
It will all depend if you live somewhere with carbon repair experts close to you, because on some countries once you crack it, it's goodbye.
love this chick
If in buying carbon I'm owning the cons.
And because im not in a place where i can own the cone I'm buying steel bikes. I'll take the weight penalty for repairability
Follow up with the result please
Carbons really pricey in ph though 😔
This won't work, because the tape is not blue 😂 Jast a joke! Thanks for cool video🤘🏻
Russian joke?
Carbon bike sit at home for display. Aluminum alloy for riding. 😊
For what that repair cost (labor intensive) i could buy a replacement aluminum frame and do it all myself and not miss a minute of riding time. But i guess if you got the big bucks and loads of time go for it. Great job. Your like a new bike. Does a great job all while being easy on the eyes. Dont stop now keepemcoming.
for real man
@@alf3071 "for real dude"
You can do this type of repair at home for $20.. the type of people that pay to get this done are the same people that take a bike to a bike shop and pay to have brakes bled. People who don’t learn basic skills to maintain or fix a bike spend way more on bikes than a savvy willing mechanic will over a life time
@@theonemanopinion2764 Because safe and effective carbon repair is a common skill that many people learn to do at home right? 😂 Not saying you can't, but its not quite the same as basic bike maintenance, especially if you want it to look as good as new once done.
to be fair...there's a significant difference in skill and risk in bleeding brakes and carbon repair. I get your point....but I'm someone that does everything I can myself, including truing wheels...and I'm currently hestiant about fucking up a repair to my rear stay that has I think only paint cracked but could be carbon with a carbon repair. It's simply the risk involed if you do it wrong. Stuff up bleeding your brakes...just do it again. And you'll know if they are working or not once done. Stuff up the carbon repair...you might not know till you are falling off a shattered frame.@@theonemanopinion2764
Meanwhile there's me, I own 2 carbon wheel sets 💪🏻🤣🔝
I love the sound of carbon frames exploding in the morning..
The video was edited too short - we didn't see the end result!!!
Why didn’t you show what it looked like afterwards?!🤔
Sorry Steve, it takes 24hrs to cure and then it needed sanding and finishing. You can see it when I do my home re-spray job - coming soon!
@@AnnaOnTheBike cool, I was just expecting ‘24 hours later’ reveal! Great video though found it interesting to see how they do actually repair carbon!👍🏻
Probably because it looks like a dog’s dinner. See how long she’s actually riding it before the next “new bike day” post! Wouldn’t trust it personally.
Of course it was a canyon for this video more like crackyon lol
Is there any reason why you cannot tig weld a aluminium bike frame? Which would mean it is repairable. Because I guarantee I could weld a bike frame together 👍
Still For everyday rider.
Alloy is better, cheaper and most of all practical than Carbon.
It would be more interesting, if they would have used cute carbon repairer nanobots.
This video was produced by the guy who did the original Italian Job, what a ending 🤨
No carbon for me.
My deal is just that I need my bikes to work for me, not vice-versa. Upfront cost of carbon is more than I can afford, plus I don't need the hassle of wondering if there is a crack in the frame that I can't see. And no knock on those who embrace carbon, especially the racers on their bikes which can be disposed after being trashed in a spill in a corner or whatever.
You can buy a full carbon bike from on one for $1200. That’s on the road, not the frame.
@@theonemanopinion2764 That's a deal, no question, and who knows, maybe one of these days I'll make the leap, perhaps on a bike for supported rides in case I need a ride back to the parking lot. And I suppose it is just that as a year-around commuter at age 63--and thankfully so, no boasting--I still ride with the spirit of a privateer funding my way on the circuit, gotta make some money, gotta make the next race. And I feel that literally when I am racing the clock to beat the time clock at work. And nobody knows my elation when I calmly clock in and avoid a tardy with mere moments to spare. So that's all and it is all still a big adventure and big fun and perhaps when I retire I'll get a speedy carbon gravel bike and get ready to take the checkers! Watch out, people, I'm ready to rock this carbon boat. 😀
Nice 😁
I don't understand why people say aluminum is not repairable yes it requires that the frame be stress relieved after welding but that's a specialized process that can be done way more places than carbon can be repaired.
With 7005 you can even harden the weld by storing the bike for a couple of months
It is good to know it is repairable but I can’t trust any carbon frame repaired for downhill or enduro sessions. I’ve been riding aluminium frames for decades but I think I’ll go back to steal frames. There are boutique frame companies here in uk or anywhere in Europe but they are expensive at the moment for my budget. Best looking one is starling bikes sturn v2. For me it is top notch.
What I don´t like about the aluminum to carbon comparison is the fact that often high end carbon frames are compared to low - mid range aluminum frames making it an apple to pears comparison.
If you buy a high end aluminum frame like a Nicolai for example I bet you, this thing will be sturdy as hell and never be in need of a repair for the total product lifespan. On the other hand, an entry level carbon frame might be repairable and all, yet it would be financially insane to do so. And when we are completely honest, 90% (not a real number, based only on personal experience) of riders will go for an entry level to mid range carbon bike anyways. So yeah, while you have to live with dents in your aluminum frame, a cracked entry level carbon frame will never ever see a repair once it is damaged anyways and will certainly be thrown away and end up in a landfill as nobody really knows how to recycle this material properly and never be ridden again.
So I stay with the analysis, that for the majority of non-professionals, aluminum is the better choice. Weight savings for most riders are always stupid as long as their riding is not competitive.
His voice tone changes at the end of sentences.
When are we seeing the finishing and final results???? Would have thought they would have vac bagged it to reduce any air pockets or voids.
Sure carbon is repairable but at at the same time you can damage your frame by installing the mud guard the wrong way or overtightening a screw. I don't mean to hate but for me mtb and having to look out for every tiny detail to not damage your frame don't belong together.
~Tyre rubs on seat tube and seat stay~
Carbon frame: ermagherd RIP
Alum frame: lol
😁
😂😂😂
Aluminium would also rub just the same🙄
@@rupedog yeh but the frame would still be rideable and would take WAY longer to wear all the way through 🤣
@@stefromfortworth depends, alloy is quite thin in these areas, especially on MTB. then it would sheer... could kill you. carbon wont do that
@@MrSupermugen No you’re right, carbon would have killed you long before that point. Probably snapping after a minor rock strike.
This guy really goes the extra mile for his customers, and you want to see his painting
Aluminium can be repaired, though specialist welding.
and then heat treated and still wont be as strong and youve now spent waaaay more aswell.
modern alloy frames cant be repaired sorry.
@@MrSupermugen if it's 6061 you need a heat treatment.
With 7005 you need none after welding, you just have to store the frame for a couple of months. This alloy was developed to be welded without heat treatments afterwards
How can he not say that the repair is stronger than before, but say that is as stronger than…?
Hi Juan! Josh said a carbon repair can make a frame just as strong as the bike frame was before the repair. Hope this helps! 👍
£4500 for a mtb with a carbon frame and it can crack on one come off,I will keep my aluminium bike at least it can be welded
Aluminium really isn’t something you want to weld…
what? lol i would go through 3-4 alloys before a carbon frame, modern alloy frames are not strong at all.
Did you know the force in a strike has to be higher to damage a carbon frame than the force needed is lower for alloy?
dont ride a structurally changed alloy... EVER
dont ride a Welded Alloy frame EVER
Aluminum frames are designed to be as light as possible, so they are not strong enough to ride on when they're not heat treated. If you weld an aluminum frame, you have to heat treat it again before you can ride on it.
you can break an Alloy frame after one Come off, and carbon can be repaired much more reliably than Alloy... whats your point?
Can you elaborate on why you're suggesting aluminium isn't repairable?
You can weld it easily, but you need to heat treat it afterwards. The manufacturer knows the exact heat ramping rates to destress the welds, a business would be guessing.
You will most likely warp the frame too, all the paint will melt.
Good response from Jane there! I guess I should have said something more like “aluminium is extremely difficult to repair and not advisable ” 👍
Ideally aluminium frames are heat treated for optimal strength to increase their lifespan, in the same way that carbon fibre frames are cured in an oven during production.
The patch repair of the carbon fibre frame in the video isn't exactly "ideal" either. It's essentially on par with not heat treating an aluminium frame, meaning that it works, but for how long.
If it's 6061 you need a heat treatment after welding. With 7005 you can just store the frame for a couple of months (age hardening). 7005 Was developed to avoid expensive heat treatments after welding.
Can anyone site an instance where a well done repair failed? The "crash it trash it" mentality has some validity, but maybe it's a little too conservative especially for the crowd who cannot just drop another wad of cash on another frame. It would be cool if a youtuber did long term crack test.
How did the frame get broken in the first place? Its a myth that (quality/branded) carbon frames are fragile... see the Santa Cruz video!.. and aluminium can equally be holed or crack from an impact in a direction it was not designed for
I agree, frames are very strong when taking hits from forces and the direction of forces they were designed for- carbon or not.
agreed. I've had three incidents with cars...one serious...and the frame faired infinitely better than me. To the point I still ride it. Like anything, how you impact the frame is key. And as you say....aluminium or titanium or steel can fail
yeah, that's all good if you live in a country where you have shops or places where you can fix the carbon frame, where they have that kind of technology and tools to do a good job. But if you live in smaller town where their is LITERALLY no repair shops that work with carbon what is the reason to buy carbon their?
I would rather just stick to a metal frame and not be scared if my frame cracked after any crash. Specially when 'fixing' a carbon frame is just placing a bandaid over the crack.
Ive had huge crashes on carbons and theyve been fine...
However ive owned a heap of alloy frames that ive Dented, cracked and even some broke the headtube off.
Carbon is considerably safer to ride hands down.
No its literally fully repairing it. The original crack might still be there underneath (assuming all the carbon wasnt removed) but the carbon that replaces it makes that original carbon redundant.
Carbon repairs absolutely need to be heated during the cure cycle.
The resin for impregnation doesn't pot off under 350 degrees. Without heat, you will not pull the matrix that introduces the resin into the cloth during a cure.
This was a bandaid that will fail.
Not true on the heat treatment. With a carbon airplane fuselage, or the hull of a sailboat, how can you put the massive structure into a heat room. Therefore there are resins made for these applications. Check out aerospace resins and other types.
@@markjones7130 I've been working in aerospace for 25 years and have plenty of advanced composites training to include several courses at Abaris in Reno.
Carbon repairs absolutely need to be heat cured. Anything less is a bandaid.
We use a combination of heat sources that are all precisely controlled with thermocouples and specialized equipment.
Aerospace is typically using prepregs that do need curing at elevated temperatures. But he was using a resin that fully cures at room temperatures. That resin is designed that way.
if an alloy frame is at a level where it needs repair it is much more damaged. aluminium bends first and then cracks. carbon just cracks. no thank you. the little weight saving isnt worth my life. i ride emtb so i dont care as much about weight anyways.
I find it somewhat comical that she is holding a Canyon frame while talking about this. Currently I am waiting on a full refund from Canyon for a Spectral Mullet Frame that cracked at the shock mount around it's 8th ride. Maybe it's just luck but that never happened to me with Aluminum.
I think it's like fishing rods, there could have been a hidden/internal hairline crack that could have got bigger when you started riding. Was the bike brand new or ex demo? Only getting started trying to learn MTB skills and only ever had hardtails, though I imagine that the shock mount is a vibration and impact heavy place lol. Did you bottom it out?
Mabey it was just a bad frame lol
@@vinceking7878 Probably, it could easily just be bad luck. Yet somehow I can't see myself buying another Canyon. The worst part was their customer service was awful.
it's way easier to find somebody with a MIG welder that can weld an aluminium frame than it is to find somebody that can fix carbon fiber. Plus I'd rather have a frame that won't break than a frame that breaks but is "easier" to repair
Tell me what is your unbreakable frame? So many alu frames snap, especially on the welds.
@@Pienimusta
I've got a 90's steel frame I've done my best to break.. I think only rust will weaken it.
Welding aluminium removes the temper applied to the frame, so welding a crack is likely to make the overall frame weaker
Would definitely be better to TIG weld aluminium, much more controllable. You would then need to heat treat it.
Tig not mig
Honestly you should probably just replace a frame if it's broken, unless it's steel which can easily be welded. I wouldn't trust a repaired alu or carbon frame.
Alloy can be welded just as easily as steel. Alloy frames are welded together, if you cant trust an alloy repair, how do you trust the original alloy welded frame?
@@ibewillow Welding shops that specialize in alum bikes recommend you replace/buy the cracked park of the bike. An alum weld repair is not as atomically strong as the weld from a factory. The factory heat treats the entire frame to balance the alum structure between a weld and alum frame.
@@markjones7130 correct, and a carbon frame cant be stress tested at all. Are we comparing the strength to an original weld or the strength of a carbon join, if youre comparing it to the latter, its going to be stronger.
tell you what, broken bones arent easily repairable as well as wallets
I buy aluminum because I can't afford carbon 🤣
Ok so even if I did end up going with a carbon frame since it's repairable, where the f do i find a carbon repair specialist?🤣🤣 there ain't none near me
Exactly! 100 miles away from you and the cost of a repair is probably half the value of your bike!
Carbon is overrated garbage, destined for landfill.
My mate got a quote to fix a crack in his carbon frame which was £800 🤡
Re-welding would be about £100 from somewhere decent.
Fuck carbon. And fuck the bike industry for marketing it as the be all, end all for bikes.
Steel or Ally for life 👊🏼
Carbon is repairable and Aluminum wasn't but you can get a new frame for 4000php
I wonder if carbon haters refuse to fly on modern commercial jets made from it!
I know right? The composite material structures in aerospace and mountain bikes are built to exactly the same standards. Surely everyone knows this by now.
The difference is an A 350 typically don't get hits lateral to the fiber direction, while this can happen to a bicycle frame.
Also aerospace grade fibers and resins are made with higher standards compared to commercial grade carbon fiber materials.
Not long ago an A 380 had a tire burst at cruising altitude, it just blew away the carbon fiber panel of the wheel well beside the tire.
This video just confirms WHY I don't want carbon. I don't want a super brittle bike that can crack without me noticing or break the frame because a chain came off. Carbon = overpriced trash 🗑️
I've done diy repair on my cheapass chinese carbon frames. Easy if one have the patience. However, I will never buy a high end carbon frame simply knowing All carbon frames are held on by glue and flimsy cloths. I consider it as a disposable item and disposables should be economical
Could do that myself for £20. I’d never trust that.
How did she destroy that frame?
And carbon can be damaged without even crashing🤣🤣🤣. Just from having parts equipped to a carbon bike is already breaking it😂😂🤣😂🤣😂. Half the bike companies aren't even making aluminum bikes now and carbon fukin sucks.
your loss mr poor guy.
carbon is considerably better in every way.
@@MrSupermugen It really isn’t 😂
One small rock strike and your frame is toast. Also, poor guy? What a bellend thing to say to someone. Many steel and alloy frames cost just as much as carbon. It’s a choice. Carbon is only going to end up in landfill 👎🏼
The same damage on an alloy bike wouldn't require such a repair. By the time an alloy bike needs a repair like this, a carbon frame would be beyond safe repair.
so on which frame? is that on my 4th or 5th alloy before the first carbon?
last few years ive ruined so many alloy frames
That depends on a lot of things. Carbon is more easily damaged from an acute impact, like a rock hitting the frame. Carbon can also take more force overall than an aluminum frame can, like coming off a really tall jump and landing correctly.
The bigger feature is overall rideability, which is why it's more of a road bike thing. Carbon frames can be ridden over much rougher roads and on much much longer rides. without fatiguing the rider, where even a brand new aluminum frame would not be tolerable after a time.
Carbon , when will you people learn !
