Carbon fiber frame crack... completly not ridable?-Dave-
Jul 26, 2002 6:54 AM
Well I have this new carbon fiber bike, Got a crack between where on frame shifters would be. I am going to send it in but i was invited on this ride tomarow... Is it safe to ride? It shouldn't be the most strenuous ride but I am just wondering if I ride it, will it break in half or osmething insane like that?

I mean I have not done anything traumatic enough to crack it. Just normal riding. So I don't know... never dealt with a crack before.

Carbon fiber is pretty notch sensitive. I'd either borrow another ride or skip it altogether. Down tube takes a lot of shear forces (from torsion), and even though it wouldn't be the "most strenuous ride," you'll still be pacing torsion load on that tube. Not worth it to me.
Don't ride it, might still be under warranty. . .js5280

My guess is that if it's fairly new, it may be under warranty. Small cracks I think would be a very good indication of a manufacturing defect. If you ride it and it does crack more; you may 1) Crash and hurt yourself 2) do major damage to the bike which could make it look like a collision cause the damage and may jeopardize a warranty replacement. Not worth the risk in my opinion. Beside this is the exact reason we all should have more than 2 bikes ;-) Good luck!
