All are around the same price range - $400 for the BAlfa with seatpost, seatpost collar front derailleur and bottom bracket, $500 for the Bullit with Thomson post, salsa seatpost collar, and RF Headset, Or $400 for the Uzzi with etype derailleur (or $500 for Uzzi, KIng HS, and 2000 X-VERT DC fork, azonic stem and Easton carbon bars).

Which would you choose and why??

I have a 2002 Z1 FR QR20, some Mavic D3.1s, and some XT cranks and SRAM X.9 stuff to complete the build, oh yeah and some Avid Mechanical disc brakes.

Which sounds like the best combination of weight, durability, and travel to you???
