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.

“This is the most stable gravel bike I've ridden. I immediately felt comfortable without having to get used to any nuances. Providing handling options is fantastic and it's a smart approach to allow the customer to tune their ride characteristics.”
Neil ShirleyGodfather of Gravel
“This bike is a missile. Responsive, smooth, stiff, nimble, and it just wanted to roll fast. It's the kind of bike that lets you relax no matter the terrain. I would recommend it to anyone looking for the perfect gravel race adventure bike.”
Griffin EasterProfessional Cyclist, Road
“It is super solid. Very fast and responsive, and it looks good and fast. I think that you all knocked it out of the park on this one.”
Maxx ChanceSinglespeed Cyclocross World Champion
“The GS1 is the first (and only) gravel bike I've ever ridden, and I loved the way it opens up new routes that I used to do on my NS1, while adding a ton of comfort on the gravel roads.”
Ryan StandishProfessional Cyclist, MTB
“The bike is perfect for what it is intended. Light, fast, and beautiful.”
Christian Vande Velde7x Tour de France Finisher
