Trek Checkpoint SL 5 AXS Gen 3 - 2025

It's right for you if...

You want a carbon gravel bike for exploring the beyond, and want to save on parts you can upgrade over time. You want the gravel-smoothing benefits of IsoSpeed tech that soaks up chatter from below so you can ride stronger for longer and plenty of mounts to carry all your gear and hydration.

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 Apex XPLR AXS fully wireless drivetrain, hydraulic disc brakes, carbon seat post, and Tubeless Ready Bontrager Paradigm SL wheels with 42 mm tyres.

The final word

When you're ready to load up and explore the road less travelled, reach for the Checkpoint SL 5 AXS Gen 3. This capable and comfortable gravel bike balances price and performance with a blend of components that deliver reliably and a frame that's packed with road-smoothing features.

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
• A SRAM Apex XPLR AXS 12-speed drivetrain offers precise, fully wireless shifting that's made for the roughest roads
• 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)
