I have a 2008 Trek Pilot with a triple chain ring and hate it no big hills here and the shifting is not the greatest. I would like to convert mit to a compact. What I have on it now is Shimano 105 and would put the same quality on. Is there anything I need to know about doing this besides the need for a new front derailleur and crank.
'''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!
First, if you don't need the granny, you could just treat your triple like a double and ignore the little ring, or remove it and reset the fd's inner stop screw. I don't know why your shifting is poor but it isn't because you have a triple.
You will need the compact crank and, maybe a new double fd. If yours is the external bearing 105 (5600) you won't need a new bb.
