Trek Checkpoint SL 6
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 drive train and extra mounts for gear and accessories make this bike a true gravel powerhouse and a great choice for serious all-road adventurers.
The IsoSpeed decoupler cuts down on fatiguing bumps in gravel so you can wander more, reach new places and stay stronger for longer.
This bike is exceedingly versatile and suited to a wide variety of riding styles, including gravel rides, bikepacking and daily commutes.
Extra mounts on the top tube, seat tube and both sides of the down tube make it easy to carry extra gear and water.
Massive tyre clearance means you can use tyres up to 45 c for extra traction and stability in any conditions.
The horizontal sliding dropout makes it easy to fine-tune your geometry or run singlespeed.
