PERFORMANCE GRAVEL HAS ARRIVED
Born and tested in Utah’s Uinta Mountains, the GS1 offers off-road comfort and versatility without sacrificing speed. It’s the ultimate gravel machine: revolutionary design and cutting-edge engineering, all wrapped up in a sleek, speedy package.
Ready For Anything
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.
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.
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.
Dial In Your Ride:
Ventum Dual-Offset Fork
We know different riders have different priorities. We took handling preferences one step further with the Ventum Dual-Offset fork. The fork offers the same comfort and ride feel regardless of wheel size, and with two distinct positions (45mm or 50mm), you can prioritize a more stable ride or a quicker steering response.
The GS1 is designed to handle up to 700c x 42c and 650b x 48c tires. With the option to choose between 650b or 700c wheels and a range of tire sizes, you can adjust your setup to attack a variety of surfaces. Note that rim and tire variables can affect optimal clearance; we’re happy to help you choose the right combo.
1x or 2xDrivetrain
The GS1 offers an industry-unique compatibility with 1x or 2x drivetrain options from SRAM and Shimano, leaving open the ability to upgrade in the future.
The frame features three bottle cage mounts and one top-tube “bento”-style mount to stash your necessities.
