Hey guys,I've been riding for about a year and love the sport, however I need some advice. I've been shopping around recently after getting hit on my last bike and having the frame, shifters, and pedal ruined from the impact and slide, and I've come across an awesome deal on a Giant TCR C3. Now, the bike is 105 equipped and a double. My Scattante was full Ultegra, but a triple; with the exception of the shifters, the components are unscathed. My question is, if I replace the Ultegra shifters, can I have the 105 bike swapped out for my Ultegra stuff? I'm unsure about the swap regarding the double and triple chainrings; and I don't mind the keeping a triple set-up since I may be seeing more hills now. I've got this Ultegra stuff in my garage, and I'd hate to see it go to waste, and I'd prefer the nice parts on the bike. Thanks in advance for your help.
