I have a carbon cage XTR rear mech with a slight bend in it,enough to make it skip ever so slightly on the smallest rear sprocket.Can it be straightened?

I'd guess not, but I've never tried. You can get aftermarket replacements for around £20 if you do try and it doesn't go as planned. Are you sure it's the mech and not the mech hanger? A thought crossed my mind.....
.... you could add a sleeve over the little aluminium bit that sits in one of the cages to push the cage out, if that's the direction it needs to be bent?

Re:
I took off the offending mech and compared it with my M970 mech and there is definitely a little bend in the 972 mech.I put a square onto the mech hanger and its straight as a die.I stuck on the 970 mech and all is well.The cage pivot is where the bend is,Im going to see if it can be straightened.

Re:
Youre saying the cage is bent? Is one or both playes carbon, i thought one eax alliy but not 100% sure.
Carbon wknt bend like metal but maybe it can be reashaped when heated to soften the resign, e.g. by putting it in hot water, or if that fails hot oil.

Re:
No the cage is carbon,thats flexible,its the steel/alloy pivot that the cage is attached to that is slightly bent.

Good idea Matt,I must try that but visually the mech appears to have a slight bend at the cage pivot point.The replacement mech is indexing perfectly.
