Race-ready geometry
innovationFaster with more control
Gravel racing continues to progress – so does our tire clearance. Bigger tires mean more speed and more traction. This gives you the confidence to hit the turns and rough terrain flat-out.
RSM01 for Integrated Cockpit System
The fully integrated RSM01 stem is designed around easy stack adjustability, giving you precise control over your fit. With its low weight, high stiffness, and seamless stealth routing, it brings pro-level performance to every setup.
Compliance
Wider tires? Check. Slacker head angle? Check. Optimized carbon layup? Check. Whatever the terrain, you’re getting just the right amount of stiffness and compliance to crush the competition across scorched Spanish deserts or horizonless American gravel.
