2021 trek Checkpoint SL 6
Manufacturer Description
Checkpoint SL 6 is a carbon gravel bike without limits. It's designed to take you places you'd never reach on a standard road bike—like the mud-caked finish line of the world's greatest gravel races. A lightweight OCLV Carbon frame with gravel-smoothing IsoSpeed, a Shimano GRX drivetrain, and extra mounts for gear and accessories make this bike a true gravel powerhouse and a great choice for serious all-road adventurers.
