Trek Checkpoint SL 6 AXS Gen 3 - 2025

It's right for you if...

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.

The tech you get

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 final word

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.

Why you'll love it

• The Checkpoint's Gravel Endurance geometry lets you sit higher up and features a shorter reach to keep you comfortable on all-day gravel adventures, light singletrack, bike-packing trips and more
• Road-smoothing IsoSpeed comfort tech soaks up vibration from rough surfaces to keep you feeling fresher for longer
• You get crisp and clean shifts from the upgraded SRAM Rival AXS wireless electronic 12-speed drivetrain
• Clearance for 50 mm tyres (as measured) means that you can add extra traction and cushion for rowdy gravel roads
• You can haul it all with large internal frame storage and mounts galore on the frame and fork for hydration, front and rear racks, mudguards and Adventure Bags that were designed to perfectly fit the Checkpoint
• Dropper post and suspension fork compatible (except size XS)
