It works! This Force derailleur needed a 31.8 to 34.9 adaptor but then wouldn't swing out far enough, not enough to lift the chain to the big ring so some trimming of the internal spring was needed. I don't think it will affect strength or reliability in any way. I'll be using non indexed thumb shifters. Still waiting on a new chain too.
Also clearcoated the stem and barends over bare metal.
