I built my Coast rando last year with a RH 46/30 crankset. I'm above you by four teeth on each but the diameter is close and the distance from the seat tube is too.
I provided my mechanic some my FDs to compare with their shop stock to find the one with best fit and function. The winner of all of these was my old SunTour Superbe Pro. Nice flat side plates, fairly short cage and its radius follows the big ring radius well enough. I have had nice results with SunTour MTB FDs on lots of my bikes with double triple and compact double cranks. A $5 favorite is the X-1. The one on my commuter for ten years of year round glop exposure. Andy Cheatham Pittsburgh On Sunday, May 2, 2021 at 3:53:47 PM UTC-4 Doug Williams wrote: > I have a 58cm 650b A.
