READY FOR ANYTHING

On-Road Responsiveness, Off-Road Speed

To go from predictable road to unstable dirt, you need a bike prepared to handle new terrain with confidence. Developed with a geometry-first approach, the GS1 meets the unique demands of gravel riding.

SLEEK SPEED

Just like its all-road counterpart, the NS1, the GS1 is a refined aero bike that handles well, accelerates like a rocket ship, and looks great while doing it.

SLEEK SPEED

Just like its all-road counterpart, the NS1, the GS1 is a refined aero bike that handles well, accelerates like a rocket ship, and looks great while doing it. When paired with the proprietary Ventum stem, the fully integrated cables are completely invisible on the front end.

STABLE HANDLING

Our POP (Predictable Optimized Performance) Gravel Geometry puts the rider into the best position to handle whatever the trail may demand. With a longer top tube, slacker steering, and a compact cockpit, the GS1 is built to be secure and predictable—whether you’re climbing a rocky trail or ripping down a loose descent.
