I may be able to get a Felt F-35 at a real good price. The only problem is that it has a double crank and there are some hills where I really think I would have a problem without a triple. My normal rides shouldn't be a problem though.

So, can anyone give me an idea of what it might cost if I decided to convert to a triple with the same brand components? This is what it has (not sure what parts would need changing):

Shifters: Shimano dura-Ace 18 speed
F/Derailler: Shimano Dura-Ace
R/Derailler: Shimano Dura-Ace GS
Crankset: FSA Carbon Pro 53/39
Chain: Shimano Ultegra
Freewheel: Shimano 12-23 9s
