My Scalpel project has been started! If everything going ok, she will be done 2 weeks time. I try to explain here, what I change on the factory set up.... how I "customized" my new racing machine.
The base: it is a Cannondale Scalpel Team Replica 2009 in size L.
First step- drivetrain:
The original setup was XTR front mech, X.O. rear mech, Sram PC991 chain, Sram PG990 cassette and Cannondale SI crankset with 44-29 chainrings.
The new system :
I changed over the front mech for a Campagnolo Record, the chain for a Sram PC 991 Hollow Pins and a cassette for a XTR M970 11-32. I kept the rear mech. I saved with this around 115 gramms and I more prefer the Shimano cassettes then Sram ones.
I did some tuning on the crank set. I changed the old chainrings and star for a two piece FRM unit. It is different ratio, 42-27 which one is better for endurance racing. This part made by FRM, but you can order only from LeoRacing (LeoRacing is a italian cannondale shop, who makes and distributes lots of bling-bling cannondale specific aftermarket parts). Basically the top chainring is one piece with the starts and the small chainring fits with 4 integrated bolts with it. The weight different isn't huge (the FRM one is only 12 grams lighter) , but you can drop down your front gearing with this special bit.
