I plan on upgrading my Scalpel 800 with some new wheels, brake pads, and crankset. I may also do new pedals - something with a platform for doing the real technical stuff.

Here's what I'm looking at:

Chris King hubs with Mavic Crossmax SL rims
Truvativ Stylo Team crankset
Time ATAC Control Z pedals
Kool Stop brake pads

Maybe a Lefty fork? I have to talk to my C-dale rep.
