Hey everyone! I've fell on a sidewalk on a very low speed while stopping and hit the frame of my Canyon Endurace CF7 LTD (and my head…) back in November. I didn't do a detailed enough inspection and thought everything is ok, and cycled around 250km more after that. Today I've was cleaning the bike and noticed this. I think that the crankset hit the frame on impact. Does it look like a trouble or not? Looks like a paint crack, but I might be wrong. Appreciate your insights!

cooked. I mean it can be repaired, but your options are try and get a warranty replacement. They will probably come at you wish a crash replacement where you pay a good deal for the frame but at a discount from MSRP, but you could argue that the derailleur was never setup properly and that’s what caused the damage
If that’s carbon it can be repaired but will cost you several hundred dollars. That is more than a paint chip.
It’s in such a non visible area, I’d just patch it myself. Doesn’t need to look pretty.
That is from chain suck not from a crash.
RIP 🪦
That is going to be one of the most reinforced areas of the bike in terms of how much carbon should be there. But at the same time that’s also your problem. If that gives way, it would take a good shunt to do it. Likely at speed, which is why you have to get that looked at or replaced.
The ping test can certainly help.
However, I personally would not feel comfortable riding that frame.
For your next bike, I recommend: 1) a chain catcher which will prevent the chain from over shooting the small ring; 2) some type of protective tape where the chain and the frame meet in these scenarios.
Because my frame has a circular seat tube, I use a dog fang. But there are models which resemble a stick.
People will argue if you use #1, you won’t need #2 and they may have a valid argument. Personally, I feel better with the redundancy on my frame. They’re inexpensive, very little maintenance (just check the bolt on the chain catcher from time to time), and trivial in weight.
