Hi, I am a newbie to road bikes. I am considering buying a bike with following components:
Crankset FSA Carbon Pro Compact
Front Derailleur Shimano 105
Rear Derailleur Shimano Ultegra
Rear Cogs Shimano 105, 10-speed: 12-25
Shifters Shimano Ultegra STI
My question is, I really need a triple for the type of riding I will be doing. Lots of hills. Bike shop has told me all I need to do is change the crankset and one of the shifters. Is this true? How much will this cost?
