Looking to upgrade my Dawes Galaxy tourer from bar end shifters to STIs.
Using Tiagra shifters and a Tiagra FD 4503 front mech, will this set up work:
48-38-26 chainset with 9 spd 11-32 cassette (my preferred choice).
Or will I be better of with this set up:
48-38-28 chainset with 11-34 cassette.
My main concern rests with the compatability of the front mech with the 26 or 28 tooth inner chain wheel. Shimano says the Tiagra front mech has a maximum capacity of 20 teeth. However, I've been told that it will accommodate a 48-38-26 chainset, which has 22 teeth max. capacity.
