Sleek Speed & Stable Handling

Building on the great design of it's NS1 all-road cousin, the GS1 is a refined aero bike with good handling, rocket-ship acceleration and great style. 

Ventum's POP (Predictable Optimized Performance) Gravel Geometry ensures the rider is optimally placed to handle all the demands of the trail.  Featuring a longer top tube, slacker steering and a compact cockpit, the GS1 is built to be solid and predictable — whether you’re storming a rocky climb or dashing down a loose descent.

“The bike is perfect for what it is intended. Light, fast, and beautiful.” – Christian Vande Velde, 7x Tour de France finisher 

“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 Shirley, Godfather 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 Easter, Professional Cyclist, Road
