The Trek Checkpoint SLR Project One Frameset in Radioactive Coral is a purpose-built gravel foundation designed for riders who want top-tier performance with a personal touch. Made from Treks lightest 700 Series OCLV Carbon, it balances stiffness and compliance with IsoSpeed tech that smooths out rough miles without dulling the ride. The progressive geometry delivers confident handling over technical terrain, while tire clearance up to 45mm make it adventure-ready. Finished in a bold, high-vis Radioactive Coral, its a frameset that stands out visually and backs it up with race-proven pedigree ready for 1x or 2x builds, dropper posts, and the kind of gear choices that turn a bike into your bike.
