I used some of my road bike components to build this up. It weighs in at 18 lbs w/ cross tires and heavy spd pedals. I've changed the seat to lighter more comfortable version after I took these pics.

Salsa Chili frame, campy components, Mavic Ksyrium wheels w/ Vitorria Cross EVO's, TRP carbon canti's, etc.

So far it's a great ride. I'm using it as a commuter and riding the trails w/ it.
