carbon Crack Or Paint Crack!?

[steve23]

there is a mark on my road frame, about 5cm from the BB on the rear left chainstay.

the mark goes vertically on the outside on the frame, for about 2cm.

i cant tell whether it is a scratch, which could of happened as its benn put in the garage and other bikes next to it, or indeed a crack!?

any advice!? ive had a ride on it, and i cant hear any "creeking" or anything untoward, but i doubt i would have. it might of been there for ages, as its a few months since ive ridden that bike!

thanks

more likely a scratch. A crack would have a jagged appearance. is it very straight?

 

[steve23]

its not very straight no, but then its not really jaggered!!!

 

[Steve Austin]

jaggered? so its an old and wrinkly crack is it?

Safest to get it checked out at LBS. Even if it is a crack it is not necessarily fatal to your frame as there are some carbon specialist about who can repair. Don't risk your neck!

on the opposite side on the frame, where the chain is, and has come off, the frame has been hit a few times, on the inside on the small chainring.

surely that is worse than the crack would be?

Just keep riding it. Do a few sprints and you'll soon have a definitive answer.

any crack you may have! it's called Carbon Repair Technology ltd.
