I totally bust my XT crank today.. Ive completely threaded the crank arm on the drive side.. its completely bust.. so bad that the pedal fell off.. well fell of in my hand lol... the threads have been a bit ropey for a while... there is no threads left..
can any one tell me the size of the threaded part M? I'm going to give a Helicoil a bash before i write them off
