I'm actually amazed at the 15:50 mark when they talk about price. This seems so labor intensive it's hard to imagine the repairs are that reasonably priced. That's awesome.
I wonder whether this is a business founded on passion for the sport or the desire to make a living. It would take a lot of repairs to pay the rent and wages not to mention the investment return on the equipment.
Seems like you could move things through pretty quickly as long as you have a decent process. Their website says most repairs are done in a day, with a few more days added on for QC, curing, and profiling. By the looks of it, it's more of a volume business than anything. That being said, for a volume business it's really impressive that they maintain such a high quality and provide a lifetime warranty on their work.
A huge congratulations to you and your team for the hard work you have put in to get your company up and running. By encouraging people to repair their frames, as opposed to buying a new one, you're also doing a huge help to the environment. I wish you all the best for the future.
this place looks like the exact place i'd wanna get my bike serviced! experts in every level and it appears to be a descent price! the work from the looks of it looks amazing!!!!
perfect timing on this! cracked my chain stay at a race a few month ago and was debating on if I should or not! for sure will now get it sent in over the winter !!
Great interview. Very thorough, and asked intelligent questions that required thoughtful responses. That’s an amazing shop. Entirely impressed with the quality of work. Nice job.
That’s the most thing that I love about CF, if damaged it’s always repairable to become brand new again :-) Also hats off to those gentleman and their tremendous amount of skills and mastery with such a cost, massive respect.
I had my carbon Specialized frame repaired a couple of years ago and it didn't look as good as these did. I am very impressed with their work. My Specialize frame lasted another year of riding didn't look as cool as it originally did when I first bought it but I was able to put a ton of more miles on it after the repair was made
Having made fiber-reinforced composite helicopter parts for the most advanced helicopters in the world, I recognize the challenges Carbon Bike Repair faces in repairing CF bike frames. It looks like they are doing a great job at it, and going the extra mile...and the price estimation Mr Granville stated to fix a chain stay, a very respectable price! Great video GCN!
I know a helicopter mechanic in Connecticut that uses cyanoacrylate (generic crazy glue) + bicarbonate of soda (baking soda) for repair of carbon reinforced parts, regularly. It cures to a harder & even more durable finish.
I'm unfortuantly in this position currently; my Thule carrier broke on route to a race and my TT bike dropped onto the roof bars cracking the rear triangle. Safe to say every single day I look at the bike now and see the crack it breaks my heart all over again. So its nice to know I can save my pride and joy :)
yes very much so, next year I'll most likely be selling my 3yr old CX bike and build me a new gravel bike, I've seen a carbon fiber frame I could build up below €2K I think running shimano 105
I had my carbon S-Works repaired a few years back and it rides and looks absolutely perfect. They even repainted the cracked area. It was a massive relief. It is practically invisible, I'm sure I could even sell it without declaring it had happened... :-)
Crashed in the sprint of BxlTour18 in June. My beloved Specialized Roubaix had a long gaping crack in the seat tube. Terminal said the bike shop. Found a specialist carbon technician here in Brussels who said it could be repaired. €200 only, and guaranteed for 5 years. I've just come back from a ride on it and watched this whilst recovering. Couldn't be happier!
I'm sure you had my Canyon frame in your hand. Chain stay damage totally blown away by the repair and Matt paint match. Highly recommend CBR. Very good to deal with, as mentioned communicate by phone and or email for quote. Compare the price of a new frame against a CBR. Even under a crash /accident replacement scene Canyon wanted £1500 for a new frame. CBR goes without saying. Great video.
They can absolutely be repaired, punched a hole in mine, had to be sent interstate to the only repairer in Australia that specialized recommend. Perfect repair, yet to meet a person who can tell it’s been repaired. Pretty $$$$ to repair, probably should’ve bought a new frame! But can’t put a price on sentimentality.
Yes you can, most of the time. A friend of mine repairs carbon bike breaks in the area I live in for alot of cyclists. He is a Carbon Fiber Materials engineer at a company and does this on the side. Mine is personally fixed by him and has been running awesome for 4 years strong.
I have my bike in for a break right as we speak. I hope my carbon guy does as good a job as these people do! It's so good and reassuring to see utter professionals talk and work like this.
At the tender age of 60 and a ¼ I've just purchased my first carbon fibre gravel bike and live in fear of it cracking under the strain of my relatively inept cycling technique. Having seen this video, I need worry no longer as this looks an amazing repair shop and located not that far from me. So thank you for the heads-up GCN.
Besides the total dedication to a seamless repair, what also stands out is their dedication to protect their workers. Compared to Look where you see employees sanding, grinding, drilling and painting carbon frames without masks, out in the open, CBR has sealed rooms and workers wearing protective respirators. Tip o the hat to Rob for protecting his most valuable assets.
@@yourhandlehere1 A GOOD carbon bike is stiffer than the best aluminum bikes. But also has a much smoother ride, more aero and better fatigue properties. Price is important. But price is the only place where aluminum wins. Personally, if I wasn't racing, I'd take an $1800 carbon bike over an aluminum bike with $2500 components and $3000 wheels. Or even a used carbon bike for under $1000
Still doesn't answer how you break a bike by riding it. You're talking about thousands of dollars...and bicycles that won't hold up to regular use as a bicycle.
Excellent video, informative, interesting, and entertaining. Hopefully will never need their services but good to know they exist and do such high quality work with tremendous dedication.
Just cracked or broke the top tube close to the saddle post. This is a great video to understand if I should get a new bike via homeowners ins. or have mine fixed!
Really interesting. I carefully shield my Serotta Ottrott from potential harm and pray it never needs repair. But if it ever does it seems like three are more options than I’d known. Thanks.
Fantastic insight into what can be repaired, always thought it would be prohibitively expensive to get a frame repaired. Great video Ollie, interesting and well worth making. Keep em coning.
I bought a fork and seatpost online and got a damaged frame with it for free. The guy wanted to throw it in the bin and I just couldn’t let that happen. I had it repaired and it’s now one of my all time favourite (and fastest) bikes. I ride it multiple times a week and so far always with a smile from ear to ear.
Been looking for a video on this. Not that much out there. Just found a crack in my Bianchi frame. Sent it back to them for what I assume will be a similar diagnostic process.
Oliver has made a strong impact on GCN in a positive way. More of this please! #askgcnanything have any of the GCN presenters ever broken a carbon frame?
Repairing damage (cracks, not cosmetic scratches) from an accident or travel mishandling makes no sense. Manufacturers should do as they do in the case of helmets. Take any damaged frame back and replace it for a reasonable or nominal fee of just $500. Carbon fiber frame manufacturing is so scaled up nowadays and quality so good that it makes it easy to produce a frame at low marginal cost (a few hundred dollars). Manufacturers can gain much more by removing the damaged frame from use, analyzing it where necessary, and just keeping the customer happy on a new frame. It also creates an incentive for end users to register their frame so as to prevent piracy and counterfeiting. As long as manufacturers chase the goal of reducing frame weight, frames will become more prone to damage and harder to repair -- hence the need for a better warranty and accident replacement policy.
I am liking the fact my bike has an aluminum frame more and more. I'll take the extra weight over the possibility of major heartache associated with a damaged frame. My fork is carbon, but a broken fork isn't the same as a broken frame.
Crashed a few weeks ago. Broke my pelvis and separated my shoulder, but after the doctor told me I'd eventually get back to 100%, my first thought was, "was my bike ok?"
At CBR: you should try out ultrasound scanning for structural analysis. It can even detect production flaws, which can’t be seen on the surface or through thermal analysis (here misleadingly called “x-ray”), and it’s cheap, unlike actual x-ray scanning. By the way, CANYON in Germany do actual x-ray scans of carbon parts and frames for about 100 to 500 €.
As well you should be paranoid. I was. I would monitor each "scratch" . If I saw it grow in length then I know I had a problem. Tap the scratch with a quarter. If scratch appears dead in ringtone compared the area next to it you might have a problem. Not totally scientific but its worked for me in certain situations.
Proves the worries. Here i saw another 50 reasons to never buy a carbon farme, fork, wheel, seatpost, handlebar, seat or pedal. Also made my experience that 1kg at the frame doesnt matter as much as 200gr at the wheels, or how much effect the profile of the tire has. It's insane.
I am riding on a repaired 2016 Trek Domane (and have been for nearly a year), with no issues. The repair was to the downtube, where you would think would be critically important. I bought the repaired frame on eBay for a good price after I crashed my 2015 Trek Madone and was told that it was NOT repairable. The Madone was cracked at both the top and bottom of the head tube (after I crashed into the back of an illegally parked pick-up truck that shouldn't have been there). I actually rode the bike home after the crash, as I didn't notice any damage at first. It was only the next morning when I really looked closely that I could see the buckles in the paint at the top and bottom of the head tube. Inspect a crashed frame carefully before you ride it! I wonder if CBR could have repaired my Madone frame??????
That's a strange way of assessing damage. I believe ultrasound testing and proper x-ray is what the aerospace industry uses to check carbon fiber voids and cracks.
@@magpiegroup I do not agree on that subject. My personal experience ist that a coupled one sided ultrasonic testing is by far superior to thermography and visual methods. For instance high energy impacts can often be not detected by thermography. The obvious downside is the high cost for the equipment and the high amount of labour needed.
Fabi Volle Hi Yes I do not disagree with what you’re saying at all. We use ultrasound and many other ways how to detect a fracture for whatever reason the video only shows the thermo image as a solution. The most effective is the stress test for us I have to say. The cost for certain equipment is the issue. If some detect the issue by tapping a coin on helicopter blades and judge the result that way fine by me as I am not an expert in heli blades. The facts are in numbers so I guess we must do something right. I went from one industrial show to another and researched many new technologies but I have only realised that there is so much rubbish out there that might deal with one issue but not the other. Lot of it is absolute waste of money and only brings me back to my own senses and find the best way on how to deal with problems and cherry pick the latest technology that might suits the best for what we do. In terms of finishing and paint the same issue. You ask 100 people for opinion , you’ll get 100 answers. So I take your opinion but I still have my own one. Thanks
How can there be any dislikes on this vid....??? 😲 😲 😲 Absolutely Awsome. 👍 👍 👍 I knew carbon could be fixed, but this is a different level. So, almost exactly 2 years ago I was knocked off by a car. Proper front end T bone, over the bonnet, right shoulder/back through the windscreen, ragdoll mid air manoeuvres and then tarmac... 🤕. His insurance paid up.... In the end.., but didn't want the bike back. Now, it was a Trek P1 Madone (2011) and was my 40th bd present. Still got it, and now wondering whether to have it repaired,bearing in mind the top tube is smashed through and there is a split in the down tube and a bent mech hanger..... It's worth asking right???
"Cracking or breaking your carbon bike frame is every cyclists worst nightmare." Olie, that's not true. I speak in the name of those who are riding aluminium and steel. Have some respect for us poor one, kids, students and rest of non-western world. My experience with carbon was in 2006 when Need for speed Carbon came out. But yes, we all dream about it. It's good to know that it can be repaired. Nice video, just, that first line.... :) Can't wait more stuff about graphene.
I am intrigued to how the new carbon fibre is laid up in an existing frame. As I understand it most frames are made by laying material into a mould with an airtight bladder in the centre. The bladder is filled with air and the pressure causes it to push the material and resin together against the inside of the mould and squeeze out voids. But when you repair the frame it is no longer in a mould and I'm guessing you cannot put a bladder inside it. How do you apply pressure to the new carbon fibre to remove voids?
The aviation industry actually has less strict requirements than the high end, bike market. Their parts are so big, and they aren't gram pinching the way the bike industry has to gram pinch. Also, the carbon parts on bikes are very complex relative to the body of a plane. Planes use huge curves that carbon can easily follow in larger pieces. An F1 carbon expert would have much more sensible use here. Obviously, personal interest is a factor. But apples to apples, F1 is much more useful to biking than aeronautical engineering.
@@fissionchips8840 I've seen his channel. I'm making an industry statement from one to the other. Planes are built with an excess of carbon. They need to be for safety reasons. Bikes barely need any excess. Planes are also built to have parts replaced modularly as things fatigue. Everything is inspected, all the fucking time. Tons of people unknowingly ride carbon bikes with unseen cracks, most get away with it. Planes? Take the part off, put a new part on. Very different world
@@fissionchips8840 By the way, I spent years repairing carbon bikes. I had a NASA engineer's ear(HS friend and teammate) and he said that his applications for carbon aren't really anything close to the same as the bike industry's. Of course, ANYONE can take it upon themselves to become an expert, even if it's not their specific field. Degree or not. I'm a fabricator of all sorts. I ask for assistance when I have questions. That said, I grew up next to a guy that built a world record speed boat. One of the first carbon hulls(he's just a cop, started with fiberglass and moved on with the times. He's still consulted by top teams in the Mid-Atlantic. Dude would never be able to get a degree in any field of science. He's buddies with the Parlee folks from the sailing industry. Also more relatable than aeronautic engineering in many ways.
@@veganpotterthevegan regardless of myself and veganpotter disagreeing please do check out Raouls videos he really is the industries go to guy on carbon bikes. I removed my last comments even though I stand by them as I don't wish to fall out with anyone.. I just find it very frustrating working in the industry and studying for 5 years of my life and working on the aviation side of things for 17 years to be told something which is clearly not the case but I think myself and veganpotter will just have to disagree. I work for bae systems, folk in the UK will know that we have contracts with the military and that I can't divulge much more but I can assure you aviation industry has a stricter code of practice especially on parts such as aircraft frames, which need to be tested destructively stress, fatigue and non-destructively fiber orientation, delamination, bonding.. Carbon prefers organic shapes than squares etc agreed but in the comments above one is assuming that carbon is just used for the wing structure.. But hey I'm not going to fall out with anyone.. The fact of the matter is carbon is great and here to stay but be very careful who you trust your repair with as you would with any industry. . And do check out Raouls site.. If just to see inside a 2017 cannondale.. Oh and next time your on a plane ✈ rest assured we have a very strict code of practice 😁👍
Would have liked to see more indepth how they actually remove the cracked spot und how they fill it with new carbon patches etc. so it does look like original when painted.
How much interaction do these guys do with the OEM? I would be curious if they have ever uncovered any design and/or manufacturing defects on the part of the OEM. How many counterfeit frames have they uncovered?
Excellent video Ollie. Not too advertorial which can be a challenge. Looked very professional and indicative costs seemed well worth it, particularly if there is a good warranty.
Great video GCN... but you need to speak to the guys at Calfee about carbon repair... They did my Cervelo S2 repair four years ago and gave the work a ten year warranty
Very professional and nice work guys doing.... still repaired bike wont ever behave same and have characteristics as original as tensions and load will find finally repaired section. Repair will just extend a bit life of the frame till you can buy new one. Not sure I`ll be confident to ride fast on repaired frame :D
Have you ever try to broke a wood stick and glue it back ? Is it as strong as before ? No Carbon fiber is the same, your "tubes" a made from long fibers shsets if you patch up with small pieces you loos some of the initial properties. But it's cool that this guy's are offering this service, it's better than trashing
I found out from PPG that it is impossible to keep any spray paint booth "COMPLETELY DUST FREE" due to air pressure changes when you bring in this case ,"A BICYCLE FRAME" in for painting / spraying , even if the booth fans/filters , have been on a few minutes before bringing in the task . Robert from carbon repairs didn't tell us this limitation . I found this out using a new booth 10 years ago with a body refinisher . If there is air movement as you enter , there will me a very small amount of dust inevitably entering no matter what you do .
Ollie I have a question. CBR says the bike after repaired ends up being the same as it was originally in strength, flexibility, modulus etc. But how is that possible? The bike manufacturers say they use various moduls carbon pre-cut sheets layered in different orientation. Can they really replicate? Or are the manufactures just selling us spin? And are the bike manufacturers all using the same carbon fibre but just call it different names?
Yes, mine broke, got it fixed and runs like a charm. Seat tube (frame) crack under (1 cm) the end seat tube imself. Add an internal tube of carbon (from an basique over seat tube), and repair outside the crack with 6 (yes 6) layer of carbon, posed one by one, one every day; with patience, compressing, heat and sanding. Bike ready than before, maybe better than before. For all : take really seat grease spécial carbon INTO your seat !! really really ! My damage comes from the former/before owner who has his seat lower than me, this creates a point of friction, of internal fragility (I'm french, I hope it's understandable) See ya alll :D
So I have been told that carbon forks are non repairable due to their flex characteristics. What's the word GCN? Thanks again for the great content! #askanything
I bet there's a lot of manufactures cringing right now when they've seen their frames in the background. I'm not saying those frames have failed due to manufacture error, but it never looks good. Interesting video, cheers GCN
That was deeply interesting! For anyone that have or will got a carbon bike, this is a certain concern. I know of one carbon repair shop here in Brazil. I would lovo to know how they are compared to those amazing folks at Carbon Bike Repair.

It is not so much about not being able to visualy detect the repairs, which of course is great, it is about structural reliability of the repair.
This repair and restoration process is extremely impressive. Even more than making the CF bikes.

Crashed a few weeks ago. Broke my pelvis and separated my shoulder, but after the doctor told me I'd eventually get back to 100%, my first thought was, "was my bike ok?"
At CBR: you should try out ultrasound scanning for structural analysis. It can even detect production flaws, which can’t be seen on the surface or through thermal analysis (here misleadingly called “x-ray”), and it’s cheap, unlike actual x-ray scanning. By the way, CANYON in Germany do actual x-ray scans of carbon parts and frames for about 100 to 500 €.
:-) we do have it and use it as well.
Marek Homola Ah ok, that’s nice. I was just wondering why it wasn’t in the video, because personally I would consider it as the main analysis tool.
A cracking video.
Fantastic video! However I’m now paranoid about every single scratch on my bike 😱😩
As well you should be paranoid. I was. I would monitor each "scratch" . If I saw it grow in length then I know I had a problem. Tap the scratch with a quarter. If scratch appears dead in ringtone compared the area next to it you might have a problem. Not totally scientific but its worked for me in certain situations.
Proves the worries. Here i saw another 50 reasons to never buy a carbon farme, fork, wheel, seatpost, handlebar, seat or pedal. Also made my experience that 1kg at the frame doesnt matter as much as 200gr at the wheels, or how much effect the profile of the tire has. It's insane.
At 15:00 I could see the repair there is a bit of dry over spray, matte is almost impossible to blend, they did a great job
god, what a pain.
With titanium being $8 per lb (bulk pricing), it's time to change the bike frame industry.

I am riding on a repaired 2016 Trek Domane (and have been for nearly a year), with no issues. The repair was to the downtube, where you would think would be critically important. I bought the repaired frame on eBay for a good price after I crashed my 2015 Trek Madone and was told that it was NOT repairable. The Madone was cracked at both the top and bottom of the head tube (after I crashed into the back of an illegally parked pick-up truck that shouldn't have been there). I actually rode the bike home after the crash, as I didn't notice any damage at first. It was only the next morning when I really looked closely that I could see the buckles in the paint at the top and bottom of the head tube. Inspect a crashed frame carefully before you ride it! I wonder if CBR could have repaired my Madone frame??????
That's a strange way of assessing damage.
I believe ultrasound testing and proper x-ray is what the aerospace industry uses to check carbon fiber voids and cracks.
Well a many million£ airplane versus a 1000£ bike frame does warrant a higher cost
Exactly, it would cost 2k to repair your 2k frame
We do use ultrasound as well but believe me there is better way to check your bike. Therefore the lifetime warranty.
@@magpiegroup I do not agree on that subject. My personal experience ist that a coupled one sided ultrasonic testing is by far superior to thermography and visual methods. For instance high energy impacts can often be not detected by thermography. The obvious downside is the high cost for the equipment and the high amount of labour needed.

Hi
Yes I do not disagree with what you’re saying at all. We use ultrasound and many other ways how to detect a fracture for whatever reason the video only shows the thermo image as a solution. The most effective is the stress test for us I have to say. The cost for certain equipment is the issue. If some detect the issue by tapping a coin on helicopter blades and judge the result that way fine by me as I am not an expert in heli blades.
The facts are in numbers so I guess we must do something right.
I went from one industrial show to another and researched many new technologies but I have only realised that there is so much rubbish out there that might deal with one issue but not the other. Lot of it is absolute waste of money and only brings me back to my own senses and find the best way on how to deal with problems and cherry pick the latest technology that might suits the best for what we do. In terms of finishing and paint the same issue. You ask 100 people for opinion , you’ll get 100 answers.
So I take your opinion but I still have my own one.
Thanks
Pretty good value.
I'll admit, that's actually a lot cheaper than I expected too! Very cool.
How can there be any dislikes on this vid....??? 😲 😲 😲
Absolutely Awsome. 👍 👍 👍
I knew carbon could be fixed, but this is a different level. So, almost exactly 2 years ago I was knocked off by a car. Proper front end T bone, over the bonnet, right shoulder/back through the windscreen, ragdoll mid air manoeuvres and then tarmac... 🤕.
His insurance paid up.... In the end.., but didn't want the bike back. Now, it was a Trek P1 Madone (2011) and was my 40th bd present. Still got it, and now wondering whether to have it repaired,bearing in mind the top tube is smashed through and there is a split in the down tube and a bent mech hanger.....
It's worth asking right???
"Cracking or breaking your carbon bike frame is every cyclists worst nightmare." Olie, that's not true. I speak in the name of those who are riding aluminium and steel. Have some respect for us poor one, kids, students and rest of non-western world. My experience with carbon was in 2006 when Need for speed Carbon came out. But yes, we all dream about it. It's good to know that it can be repaired. Nice video, just, that first line.... :)
Can't wait more stuff about graphene.
Nikola Pocrnja Nothing wrong with steel or aluminum! There are some awfully expensive steel frames out there too...
Maybe should I said old steel bikes. Ofc that custom made ones are expensive. I've had reynolds and cro-mo and would do it again. Cheers!
17:31 “we’ve only scratched the surface”... phew!
I am intrigued to how the new carbon fibre is laid up in an existing frame. As I understand it most frames are made by laying material into a mould with an airtight bladder in the centre. The bladder is filled with air and the pressure causes it to push the material and resin together against the inside of the mould and squeeze out voids. But when you repair the frame it is no longer in a mould and I'm guessing you cannot put a bladder inside it. How do you apply pressure to the new carbon fibre to remove voids?
Please, GCN, go and interview Raoul Luescher. That's the real guru about carbon repair. PLEASE. Do us and you that favor.
The aviation industry actually has less strict requirements than the high end, bike market. Their parts are so big, and they aren't gram pinching the way the bike industry has to gram pinch. Also, the carbon parts on bikes are very complex relative to the body of a plane. Planes use huge curves that carbon can easily follow in larger pieces. An F1 carbon expert would have much more sensible use here. Obviously, personal interest is a factor. But apples to apples, F1 is much more useful to biking than aeronautical engineering.
Agree , he has TH-cam page with name Luescher Teknik.
He's got the best content on Crabonfiber on TH-cam
@@fissionchips8840 I've seen his channel. I'm making an industry statement from one to the other. Planes are built with an excess of carbon. They need to be for safety reasons. Bikes barely need any excess. Planes are also built to have parts replaced modularly as things fatigue. Everything is inspected, all the fucking time. Tons of people unknowingly ride carbon bikes with unseen cracks, most get away with it. Planes? Take the part off, put a new part on. Very different world
@@fissionchips8840 By the way, I spent years repairing carbon bikes. I had a NASA engineer's ear(HS friend and teammate) and he said that his applications for carbon aren't really anything close to the same as the bike industry's. Of course, ANYONE can take it upon themselves to become an expert, even if it's not their specific field. Degree or not. I'm a fabricator of all sorts. I ask for assistance when I have questions.
That said, I grew up next to a guy that built a world record speed boat. One of the first carbon hulls(he's just a cop, started with fiberglass and moved on with the times. He's still consulted by top teams in the Mid-Atlantic. Dude would never be able to get a degree in any field of science. He's buddies with the Parlee folks from the sailing industry. Also more relatable than aeronautic engineering in many ways.
@@veganpotterthevegan regardless of myself and veganpotter disagreeing please do check out Raouls videos he really is the industries go to guy on carbon bikes. I removed my last comments even though I stand by them as I don't wish to fall out with anyone.. I just find it very frustrating working in the industry and studying for 5 years of my life and working on the aviation side of things for 17 years to be told something which is clearly not the case but I think myself and veganpotter will just have to disagree. I work for bae systems, folk in the UK will know that we have contracts with the military and that I can't divulge much more but I can assure you aviation industry has a stricter code of practice especially on parts such as aircraft frames, which need to be tested destructively stress, fatigue and non-destructively fiber orientation, delamination, bonding.. Carbon prefers organic shapes than squares etc agreed but in the comments above one is assuming that carbon is just used for the wing structure.. But hey I'm not going to fall out with anyone.. The fact of the matter is carbon is great and here to stay but be very careful who you trust your repair with as you would with any industry. . And do check out Raouls site.. If just to see inside a 2017 cannondale.. Oh and next time your on a plane ✈ rest assured we have a very strict code of practice 😁👍
Would have liked to see more indepth how they actually remove the cracked spot und how they fill it with new carbon patches etc. so it does look like original when painted.
amazing, will be in touch with them now for a quote on my mountain bike
I'm getting deja vu from a cycling weekly video
Glad it's not just me!
12:06-12:17 the mark of a true repair artist.
Now I almost want to break my bike just to go here! Amazing video!
Well glad you enjoyed the video!
Oli upping his game for GCN - he got the company name right this time :p
How much interaction do these guys do with the OEM? I would be curious if they have ever uncovered any design and/or manufacturing defects on the part of the OEM. How many counterfeit frames have they uncovered?
Excellent video Ollie. Not too advertorial which can be a challenge. Looked very professional and indicative costs seemed well worth it, particularly if there is a good warranty.
Great video GCN... but you need to speak to the guys at Calfee about carbon repair... They did my Cervelo S2 repair four years ago and gave the work a ten year warranty
Fantastic service. Very impressed by the repair price.
Very professional and nice work guys doing.... still repaired bike wont ever behave same and have characteristics as original as tensions and load will find finally repaired section. Repair will just extend a bit life of the frame till you can buy new one. Not sure I`ll be confident to ride fast on repaired frame :D
Have you ever try to broke a wood stick and glue it back ? Is it as strong as before ? No
Carbon fiber is the same, your "tubes" a made from long fibers shsets if you patch up with small pieces you loos some of the initial properties.
But it's cool that this guy's are offering this service, it's better than trashing
I found out from PPG that it is impossible to keep any spray paint booth "COMPLETELY DUST FREE" due to air pressure changes when you bring in this case ,"A BICYCLE FRAME" in for painting / spraying , even if the booth fans/filters , have been on a few minutes before bringing in the task . Robert from carbon repairs didn't tell us this limitation . I found this out using a new booth 10 years ago with a body refinisher . If there is air movement as you enter , there will me a very small amount of dust inevitably entering no matter what you do .
Great video. Makes a person more apt to get a bike repaired. I know I have really thought twice about cf frame repair.
Glad you enjoyed the video Timothy!
Ollie I have a question. CBR says the bike after repaired ends up being the same as it was originally in strength, flexibility, modulus etc. But how is that possible? The bike manufacturers say they use various moduls carbon pre-cut sheets layered in different orientation. Can they really replicate? Or are the manufactures just selling us spin? And are the bike manufacturers all using the same carbon fibre but just call it different names?
Easily.
It is very possible with use of fancy lies and some journalism magic on top of that.
Fantastic video, really demystified a lot of this process. Often seems like black magic to me.
i like how the boss touch the tech manager and said he is the genius
Yes, mine broke, got it fixed and runs like a charm.
Seat tube (frame) crack under (1 cm) the end seat tube imself. Add an internal tube of carbon (from an basique over seat tube), and repair outside the crack with 6 (yes 6) layer of carbon, posed one by one, one every day; with patience, compressing, heat and sanding. Bike ready than before, maybe better than before.
For all : take really seat grease spécial carbon INTO your seat !! really really !
My damage comes from the former/before owner who has his seat lower than me,
this creates a point of friction, of internal fragility
(I'm french, I hope it's understandable)
See ya alll :D
So I have been told that carbon forks are non repairable due to their flex characteristics. What's the word GCN?
Thanks again for the great content!
#askanything
Very intresting!!! Question: what about carbon wheels? Are they repairable?
According to their site they can.
As long as you use a resin that won't melt when the rim brakes get hot
I bet there's a lot of manufactures cringing right now when they've seen their frames in the background. I'm not saying those frames have failed due to manufacture error, but it never looks good.
Interesting video, cheers GCN
A video about carbon rim repair would be much appreciated. Thanks
Guy is clearly very professional.
Ah man I love my alu and steel frames more after watching this =)
pepperonization Why? Aluminum frames cannot be repaired like this. Once they are bent, good luck with trying to get them back to original state
Took the words right out of my mouth... go and see Raul Luescher!
Excellent video, such dedication and attention to detail at CBR
That was deeply interesting! For anyone that have or will got a carbon bike, this is a certain concern. I know of one carbon repair shop here in Brazil. I would lovo to know how they are compared to those amazing folks at Carbon Bike Repair.
thank you very much.Quick shipper.Good Product.
So didn't expect it to be that cheap. Nice one!
why would 183 viewers dislike this video???... anyway, i'm amazed how much effort, knowledge and passion they put on this!!! love them!!
because some of the claims are just too optimistic.
Super interesting! Thank you for sharing.
