My buddy is looking for a cross frame. He has a 52 cm Trek 2100ZR frame set that he would like to swap for your equivalent level cross frame. His frame has an aluminum front triangle with carbon seat and chain stays. The fork is carbon bontrager. Also included are cane creek headset and brake calipers, bontrager seat post collar and braze on fd clamp. Contact me to see photo. My friend is at most 5'6" and has proportionate torso/leg ratio. So if you have 50 cm cross frame you'd like to swap contact me. (or 48 cm Ridley).
