Not sure if I can remove the claw and just bolt it on, or if it will screw up the pivot spring. Sure wish these had b-screws. I'm afraid the pivot spring in this one has given up. There is some tension, but the derailleur is pointing so far forward that the chain wrap at the cage is wierd looking. It also has difficulty shifting up the freewheel, getting hung between the big and 2nd gear down. The lowest gear I run is a 40t front, 28t rear.

Yeah, I know, it needs a new cable too.

My bike on the left. I also want to raise the brake levers a smidge, which means re-wrapping the bars.
See if my thread helps you. I had a similar issue a few years ago and the tutorial from another member worked like a charm!
