Trek Checkpoint SL 6 AXS - Red - 54

The Checkpoint SL 6 AXS is a carbon gravel bike designed to take you to places you'd never reach on a standard road bike. Built on a lightweight 500 Series OCLV Carbon frame with gravel-smoothing IsoSpeed technology, it dampens chatter on rough surfaces to keep you fresh for the long haul. With its nimble-yet-stable progressive gravel geometry, internal frame storage, and an abundance of gear mounts, this bike is a true gravel powerhouse—making it an exceptional choice for serious all-road adventurers. It comes completely dialed with a smart, crisp wireless SRAM Rival AXS 12-speed electronic drivetrain.
