Ok to start it off here is my bike and it's component list http://www.specialized.com/bc/SBCBkModel.jsp?spid=9634&bikeTab=techspec I'm wanting to change my 3 ring crankset to a lighter and higer end 2 ring set. I have looked at the Durace and Campagnolo Record CT or Carbon. I'm wondering several things.
1) Will my front and rear derailleurs work with the change?
2) Which would you go with Durace or Camp. record or carbon?
3) I'm 5'10 - 178 lbs what length of crank will I need 170, 172.5, 175?
4) Should I get a better cassettes to go with the front?
5) What chainring size would you go with 39x53 or 34x50
6) Anything else I'm forgeting
Thanks
