Does anyone know if you can shorten the throw and/or lessen the pressure needed to shift on sti shifters. After long rides or bigger mileage weeks my arthritis flares up really bad in my fingers which makes life a bit more difficult. Was wondering if you can alter the spring tension and throw of the levers so that it doesn't aggravate my fingers. I have bar end shifters on my cx/commuter bike that don't cause any flair ups but not too psyched about bar end shifters on my litespeed (cable stops are too high up on down tube for down tube shifters). Anyone have a suggestion?
