Trek Checkpoint SL 6 AXS Pro Gen 3

Checkpoint SL 6 AXS Pro Gen 3 is a carbon gravel bike ready for far-out adventures. Its lightweight 500 Series OCLV Carbon frame is built with comfort-focused Gravel Endurance geometry, clearance for beefy 50mm tires (as measured), and mounts for racks, fenders, and bags. IsoSpeed frame technology smooths out rough roads and potholes so you can ride stronger longer, while wireless SRAM Rival AXS E1 13-speed shifting, Aeolus Elite 35V carbon wheels, and a carbon handlebar keep the ride light, capable, and ready to cut loose whenever you are.
