Cue a new rear mech and a spoke BUT a LBS insisted that the carbon
frame is also bent and they won't put it in a jig to straighten it.
How can a Carbon stay bend?


Stress any material beyond its elastic limit (yield strength) and it
will deform and stay deformed. You can't bend it straight again..


Really.

What do you think the yield stress of, say, a china plate is?
Do you think you can bend that so it stays bent?


Doesn't every material have an "elastic limit"?
After that it snaps, not deforms.
