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.

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 dialled 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 Shimano GRX drive train with a wide-range cassette, powerful hydraulic disc brakes, Bontrager Paradigm Comp Disc wheels with 25 mm inner width rims and wide 700x40c gravel tyres that provide extra traction and stability, and a vibration-absorbing handlebar.

The final word

A carbon gravel bike built 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.
