Product Description
The Trek Project One Fuel EX Gen 6 is a versatile carbon trail platform built for riders who want confident descending, efficient climbing, and modern all-around trail performance. This bare frame uses OCLV Mountain Carbon construction and is designed around 140mm rear travel with progressive trail geometry that adds control on descents while keeping the rear end efficient under power.
As a Project One frame, it is a unique custom Trek offering rather than a standard off-the-shelf frameset. It features premium frame details like internal storage, adjustable geometry, guided internal routing, magnesium rocker link, UDH, and Boost148 spacing, making it an excellent foundation for a high-end custom build.
