Product Description
The Trek Project One Supercaliber SLR 9.9 Gen 2 is an ultra-light carbon cross-country race platform built for riders who want maximum speed, efficiency, and control on modern XC courses. This bare frame uses Trek’s SLR OCLV Mountain Carbon construction and is built around 80mm of IsoStrut rear suspension to smooth rough terrain without sacrificing pedaling efficiency.
Designed around a 110mm fork, the Supercaliber Gen 2 brings more rear travel than the previous generation along with updated geometry for a more capable and confident ride. As a Project One frame, it is a unique custom Trek offering rather than a standard off-the-shelf frameset.
