Trek Checkpoint SL 6 AXS Gen 3

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 50mm tires (as measured), and plenty of frame and fork mounts. Plus, IsoSpeed frame technology helps 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 groupset.

Features:

• 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, bikepacking trips, and more
• Road-smoothing IsoSpeed comfort tech soaks up vibration from rough surfaces to keep you feeling fresher longer
• You get crisp and clean shifts from the upgraded SRAM Rival AXS wireless electronic 12-speed drivetrain
• Clearance for 50mm tires (as measured) means 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, fenders, and Adventure Bags that were designed to perfectly fit Checkpoint
• Compatible with a dropper post (all frame sizes) and a suspension fork (all sizes except XS)
