U can check with with Calfee. http://calfeedesign.com/repair/

I know you are in HK dailo... But no special repairs in Taiwan either. At this point u might as well check with Calfee in US and see if they can repair for you.

I would not bother sending it to the US in order to fix it. Does not worth it IMO. I would get Canyon's crash replacement or look for something else. There are many slightly used top frames you can find for cheap.

You could try selling it as a cracked frame. Someone may be interested in doing the repair himself.

Thanks addictR1 - I'll take a look and figure out how's the deal with the logistics/ shipping. And dailo (bro) you from HK as well? I thought they use "dai ger" in Taiwan! Haha

Thanks kgt, I might go for another frame rather than crash replacement, all shipping and LBS costs do add up. LBS would most likely waive the labor fee thou if I purchase a frame from them.

Just a bit sad that the frame only last for <3,000 km...I didn't ride it much but atmost once per week

Thanks guys for the input. I live in Hong Kong, a relatively small community, which could be difficult to find a carbon repair specialist here, but I'll also try searching China or Taiwan as well on Google.

Cheers :beerchug:


first attempt on google

I would not get it repaired. Go with the Canyon crash replacement program. You can always sell you damaged frame.

They make you send it back.. Or in the case of the other guy in this thread show proof that he destroyed it before getting a replacement

Honestly I think that a manufacturer telling you the TT is unable to withstand leaning on it, is absolutely ridiculous. I understand the way you described leaning on it at a stoplight and.... sounds pretty reasonable to me! Of course an extremely light or boutique frame maybe is a bit more delicate and I would NEVER Clamp the top tube in a stand/rack whatever, it should be able to withstand some forces. If canyon has decided to make this frame so light that you cannot ride the way you want, or even grab the tube too hard... little sad if you ask me!

All tubes on a frame should be made to withstand reasonable impacts, I'm sure we'd all be really outraged if a bike tipped over after being leaned up against something in the shop, or at a rest stop and found evidence of carbon damage. Little rocks get kicked up off the road all the time and can cause alot more force than we may realize.

I think canyon should have agreed the warranty on this one, I've had to warranty several frames (mainly MTB) for customers, who bashed the carbon on a rock/ dropped and had an impact, and they were covered every time. Of course in one case case the manufacturer ended up tweaking the carbon layup to prevent the damage from happening in the first place.

It seems to me Canyon has major quality control issue.

Couple of days ago, one guy in S.Korea got hurt seriously because his Canyon Ultimate's fork cracked while he was riding 35-40km/h.

As far as I'm concerned, Canyon should beef up their QC process and double down on OEM management.

I've never had a Canyon but as far as I know they CT scan every fork to prevent this kind of thing.

rojya,
if ever your going the repair route, i had a cervelo R3 dropout/hanger repaired by this guy from NZ.

its the closest and most economical carbon repair i could find out of HK in terms of shipping and cost. shipped it by HK Post to NZ and ask him to ship it by NZ post on the way back to keep costs down.

Some people seem to be curious about the accident I was referring to. So, here it goes.

1. Broken fork can be identified in the photo I attached.

2. He got badly injured. His arm bone was even damaged because his arm was so badly scratched.

3. No outside force was applied to the fork.
No road block was there.

4. Canyon Korea is investgating the issue and it will decide how to handle the warranty claim soon.

I'm also in manufacturing industry.

What I realized from 4 years of exprience is there will always be faulty mass manufacturing process, so we should have wider engineering margin than what is needed in labotory situation to prevent faulty products that are even hard to find in QC process.

In terms of Canyon Ultimate, it seems to have very thin engineering margin because it is so light.
The only way to make CFRP bike frames lighter is to apply less carbon layup. There is no way around this.

I think the issue here is not product engineering.
Instead, Canyon engineered extreremly lightweight frames which have thin engineering margin.

That thin margin could result in disasterous accidents if it combines with manufacuring mishaps and spotty QC process.

Someone was referring to CT scan results. However, always keep in mind that CFRP frames are entirely manufactured by hands which mean they are susceptible to human errors, and Canyon outsources its manufacturing which means its QC process might have higher rate of failure.

I'm a big fan of Canyon Bicycles.
Although, I hope it should focus more on reliability, less on lightweight.

I crashed my aeroad and visited Canyon Finland to get estimate for insurance company.

They actually asked me if I sat on tt and told me that the tt upper part is really really thin, because it is there for only aesthetic reasons.
You can on their Speedmax (there's small cover for bits and pieces) that it is something like 1mm or even less. Didn't actually measure it, but really thin none the less.

Though I've been leaning on tt from time to time and haven't had issues. But the tt is designed to be as it is. Those cracks wont affect riding in any way.
