Designed for adventure, it features a 500 Series OCLV Carbon frame with IsoSpeed comfort technology to ensure you stay comfortable over long, challenging miles. The bike boasts a 12-speed 1x SRAM Rival AXS wireless drivetrain for reliable performance on tough gravel, while its hydraulic disc brakes provide dependable stopping power. With a carbon seat post and Tubeless Ready Bontrager Paradigm Comp wheels equipped with 42 mm tyres, it’s ready for rugged terrain. The bike also offers clearance for up to 50 mm tyres, ensuring ample traction and cushioning.
The Checkpoint SL 6 AXS Gen 3 is built to explore, with thoughtful design elements like internal downtube storage, multiple frame and fork mounts, and compatibility with dropper posts and suspension forks (except size XS). Its Gravel Endurance geometry provides a higher riding position and shorter reach, enhancing comfort during all-day rides, bike-packing trips, and light singletrack. The upgraded SRAM Rival AXS drivetrain delivers precise shifts, while generous tyre clearance and extensive mounting options let you carry all your gear and hydration packs with ease. Whether you're navigating rough roads or embarking on an adventure, this bike is ready for anything.
