I am looking at buying a second hand Trek pilot 2.1.
It comes with Drivetrain
SHIFTERS Shimano 105 STI, 10 speed
FRONT DERAILLEUR Shimano 105
REAR DERAILLEUR Shimano Ultegra
CRANKSET Shimano 105 50/39/30
CASSETTE Shimano 105 12-25, 10 speed
PEDALS Shimano 505, clipless
Some advice please - I want to put a flat bar on it for a bit. Am wondering are there rapid fire type shifters that I can put on the bars that will work well? Any warnings or things to steer clear of?
