Hi All
Here's my setup
Shifters - Shimano SL-R440 (3x9)
Front Derailleur - SL-R443
Crankset - Sora Triple (50-x-y)
BB - Octalink
Looking on the shimano website, its states that the SL-R440 Shifter does double front shifting as well

My question is, can I upgrade the crankset to a 105 double and keep the front shifter and derailleur?
