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 full Shimano Ultegra drivetrain, and extra mounts for gear and accessories make Checkpoint SL 6 a true gravel powerhouse and the best choice for serious all-road adventurers.

It's right for you if...
You have big dreams for the likes of Dirty Kanza, Land Run 100, and Trans Iowa, and know you'll need the most dialed gravel bike for these epic adventures. You also love the idea of one bike with such incredible versatility that it excels at gravel racing, adventure road riding, bikepacking, and whatever kind of ride you feel like tackling next.

The tech you get
A 500 Series OCLV Carbon frame with Rear IsoSpeed, a full Shimano Ultegra drivetrain, 700x40 Bontrager GR1 Tubeless Ready gravel tires, powerful flat mount hydraulic disc brakes, and Bontrager Paradigm Comp Disc wheels with Shimano RT800 Ice-Tech FREEZA rotors and finned brake pads for reliability and extra stopping power. Plus, Control Freak internal cable routing, a carbon seatmast cap, Carbon Armor to protect the frame against debris, 12mm thru axles, and Stranglehold dropouts that make it easy to fine-tune your geometry or run singlespeed.

The final word
Trek's best carbon gravel bike for the longest days, roughest roads, and biggest adventures. It's light, fast, comfortable, and spec'd with parts that stand up to the most rugged terrain, like the upgraded Bontrager Paradigm wheelset and a full Shimano Ultegra drivetrain.

Why you'll love it
- The IsoSpeed decoupler cuts down on fatiguing bumps in gravel so you can wander more, reach new places, and stay stronger longer
- Extra mounts on the top tube, seat tube, and both sides of the down tube make it easy to carry extra gear and water
