I have finished my bike build about two weeks now, and i am tweaking my setup here and there to tune the bike up nicely.
So about my front derailleur:
the frame-set is the Thorn Sherpa with the stock BB installed by Thorn.
the crankset is a Sugino xd600
the FD is a Shimano LX (2006/2007 model i think) suited for a 31.8mm seat tube.
the seat tube on the Thorn Sherpa is 28.6mm.
I am using a shim to mount the 31.8mm FD to the 28.6mm seat tube. but i am getting some rubbing when i am in the lowest gear combo.
So my question is:
if i were to install a FD whose size was 28.6mm in diameter (thereby not needing to use any shims) would the FD sit closer to the seat tube therefore eliminating any rubbing????
see attached picture of the bike!!!
