Is my carbon frame done?

Bicycles Asked by Bubblesphere on October 4, 2021

I have a carbon trek Emonda bicycle. Today, my rear derailleur got caught in my wheel. As a result, the rear derailleur is bent, the rear derailleur hanger snapped off, the chain got twisted and the right seat stay got scratched.

Is the scratch on my right seat stay too dangerous to ride again? It goes about 1-2 mm at the deepest part of the scratch.

I would not ride that frame as-is.

Whether it is repairable or not needs a hands-on inspection by a competent carbon fibre frame repairer in person. So you need to strip everything else off the bike and send/take the bare frame to someone who can advise professionally.

The seat stays are always in compression, take very little load and have no side loading. If you ride the bike on smooth roads you might not experience any further failure, but this is not ''sensible.''

The damage is absolutely repairable and may actually not cost very much. Certainly worth doing.

However, your lifetime warranty is no longer valid.
