The Trek Checkpoint SL 7 AXS Gen 3 is a carbon gravel bike built to explore the beyond. Its lightweight carbon frame is designed with a Gravel Endurance geometry, tons of mounts and clearance for up to 50 mm tyres (as measured). Plus, IsoSpeed comfort tech helps soak up jarring vibrations to help you float over chatter and potholes. It's decked out with upgrades where you want them most, like carbon wheels and seat post, and a wireless SRAM Force AXS D2 drivetrain.

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 upgrades that matter – like the carbon Bontrager Aeolus Elite 35V wheels and SRAM Force AXS D2 wireless electronic 12-speed drivetrain
Clearance for 50 mm tyres (as measured) means that you can add extra traction and cushion for rowdy roads and stretches of singletrack
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)
