Trek Checkpoint SL 6 AXS Gen 3 Gravel Bike 2025 in Matte Hex Blue/Marianas Blue

The Checkpoint SL 6 AXS Gen 3 is a carbon gravel bike ready for far-out adventures. Its lightweight carbon frame is designed with comfort-focused Gravel Endurance geometry, clearance for beefy 50 mm tyres (as measured), and plenty of frame and fork mounts. Plus, IsoSpeed frame technology helps to soak up jarring road vibrations, helping you float over chatter and potholes. It’s ready to cut loose with a SRAM Rival AXS wireless 12-speed group set.

You’re itching for adventure and want a bike that’s up for taking the road less travelled. You want IsoSpeed comfort tech to help you stay comfortable on the hardest miles, an upgraded drivetrain that can hang tough when the gravel gets deep and plenty of mounts to carry your gear and hydration packs.

A 500 Series OCLV Carbon frame with a carbon fork, internal downtube storage, frame and fork mounts, and clearance for 50 mm tyres (as measured). A 12-speed 1x SRAM Rival AXS fully wireless drivetrain, hydraulic disc brakes, carbon seat post and Tubeless Ready Bontrager Paradigm Comp wheels with 42 mm tyres.

The Checkpoint SL 6 AXS Gen 3 is made to explore, with the chatter-smoothing benefit of IsoSpeed, a lightweight carbon frame, and upgraded components where they matter most, like the SRAM Rival AXS wireless shifting.
