Used 56cm Trek Boone 5. I completely rebuilt this from the original Boone 5 model spec. Great handling and riding bike. I had several good races and gravel rides on this baby over the last few years. It treated me well. Overall condition is very good to excellent. It has been raced and ridden, and there are a few scars, but nothing major. Worst would be some cosmetic marks on the carbon cranks and rear der. Full specs below. Weight is 16.95 lbs as shown (no pedals.)

SRAM Force CX1 group: GXP 172.5mm carbon cranks, 38T ring, PC-1170 11-32T cassette, 1x shifters/hydro brakes, center lock 2-piece rotors 160/140.
Wheels are carbon Roval Rapide CL & CLX 40 tubulars. The rims are mixed as I cracked the original CL rear in a race and Specialized only had the higher end CLX 40 rims available for replacement purchase. Glued to those rims are Clement 700x33 PDX/MDX front/rear. Rear hub uses DTSwiss internals with 36T ratchet.
Cockpit duties are handled by a Salsa Cowbell 2 44cm bar and Salsa Pro Moto 90mm stem. Just put some fresh black bar tape on.
Saddle is an older Serfas Dual Density Pro (because nobody can have my dwindling collection of older Fizik Aliante saddles!)
Matching blue Bontrager RLX bottle cage.

Asking $1,600 shipping.
