I have one, it needs a clean and it's fitted to a crank at the mo, would you be interested in the whole ring set or just the inner?
The crank arm pedal threads are stripped as someone in the past has wound the pedal right in whilst crossed threaded and written the arm off as a result, it took me and a mate, with a bench and vice to get the damn pedal off so it must of been hard to get it right on crossed threaded in the first place!
