Hey folks,
I just received a used Canyon Exceed CF SLX from a professional refurbisher (Zyclora). My first carbon bike. Upon unboxing, I noticed these traces of "repair" near the seatpost clamp area. (and the bolt is rusted)
According to their customer service, “We showed the photo to our mechanics, this is cosmetic only, no structural issue. You can ride it no problem”
I haven’t ridden the bike yet and I am a bit doubtful about the fact that they can guarantee this bike is safe to ride with only this photo…
And I don't know what these black traces are ? Are they traces of repair or just paint on the cracks ?
Thank you !

wtf? definetly return it. would not want ride that bike..
If not disclosed on the advert would definitely try and return it! putting on my other hat I would say it is strange area for a carbon failure and looks more related to a tool strike (hex/allan key noob).
Absolutely take it back. You can literally see the cracks in the photo that they have tried to paint or Texta over. If you can feel a ridge when you run your fingernail over it then I would definitely never ride it.
Hard to tell from the pic, but looks like either something slipped from the bolt and damaged the frame or someone over tightend it and cracks. This has been covered by some for of clear coat, like a nail varnish. I’d give it back as this damage is not factored into the prixe
I’m no carbon expert one will be along shortly but meanwhile as we wait….
It looks like someone has overtighten the seat bolt clamp and the lines you can see from around the bolt are stress fractures. I’d say it’s going to be more than cosmetic and I’d return it.
Minimum I’d want a detailed explanation on exact how it got the damage, how they checked it was only cosmetic, why they thought just slapping black paint on it was anyway acceptable, why they didn’t tell you about this before they sold it to you.
You can get carbon checked using ultrasound and minimum I’d want the reassurance that this was done and a note on the warranty that if if fails at this point they will replace.
If this is the level they at which they operate and the quality of repair they deem acceptable then personally I’d get my money back and go elsewhere.
That doesn’t look like a repair, that looks like a (bad) cover up. Could be fine below those scratches, but maybe not. You cannot tell and it is a red flag that they are judging it from just the photo. I wouldn’t accept it like that.
Return it
Yikes
Send it back. Do not accept any explanation.
It’s Great Wall art. Not sure I would put up a canyon, though.
But in all seriousness – I wouldn’t ride it on smooth tarmac.
Definitely send it back. On a side note, I’ve come across all kinds of strange stories about Canyon. One thing’s for sure: I’ll never buy from that brand. Way too many red flags.
Must be the least convincing attempt to cover up frame damage we’ve seen. Kinda laughable really 🙂
Ladies and gentlemen, get yourselves a torque wrench, yesterday.
Looks like the seatpost screw was overtightened and cracked carbon around it. I would return it, cracks will keep spreading under load.
Don’t buy walk away more hassle and dangerous

Obviously, what radiates from that point are cracks and not scratches. Too much force on a part does not cause scratches, it causes cracks.
How many times have you dropped a glass on the floor and instead of the glass breaking you got radiating pattern of scratches?
That’s an obvious attempt of the seller to convince you to accept a broken bike.
How can they tell from the photo how deep the scratch is. Is it a scratch or a crack through the whole thickness of the frame?
Carbon fiber is not repairable. There exists no (economical) way to return the part to its original strength. Any discontinuity in carbon fiber, touched up or not, should result in a return.
not sure if those are cracks or just scratches but I’d return that. this “cover up” is horrendous
Looks like it cracked from overtightening. I think they removed paint to check how bad the damage is. Unless they advertised the bike like this, I would return it as I would not trust it.
Never understood what is wrong with a normal seatclamp though..
It’s dead.
Is that bolt even original?
That is one of the hardest area to be repaired and for sure is not done like that: someone retouched it badly with some paint. You can start repacking the bike and send it back.
Someone adjusted the height of the seat post, but failed to tighten down this bolt securely enough. Then, while riding the bike there was minimal rocking of the post, possibly not even noticeable, which is transfered to the bolt lug, subsequently onward to the frame causing these cracks. This is structural and not OK. Will it break? No one can say for sure, but the likelihood of it failing in a catastrophic manner is increased and should be seen as unacceptable. If your seat post collapses while going down a hill, you are f’ed. I’d rewrite the company and ask them about how high their liability insurance is, and if they really want to sign off on their claim it is OK. It is not OK.
Looks like they smeared superglue or something to smooth the crack. Not looking good though. If it’s been professionally repaired I’d like to see proof it’s not a hack job. Some repairers redo top coat and paint so a worry to see this
I seem to remember Canyons having issues with saddles slipping, looks like it’s been overtorqued trying to solve that
As I was saying over and over again: don’t buy second hand carbon frame bikes, you never know what are you getting into.
