Ventum GS1 Gravel Bike
Performance gravel is here. Meet the GS1.
Performance and Comfort
Born and tested in Utah’s Uinta Mountains, the versatile GS1 speeds you over uneven terrain in ultimate comfort. The ultimate gravel bike: enjoy athlete-led design and performance engineering, delivered in a sleek, speedy package.
Ready for Anything
Built for on-road responsiveness and off-road speed, the GS1 takes you from predictable road surfaces to unstable dirt tracks with confidence. The geometry-first approach of the GS1 is uniquely suited for the demands of gravel riding.
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.
Dial In Your Ride
Ventum Dual Off-Set Fork
Different riders have different priorities, so whether you are looking for a more stable ride or a quicker steering response, you can alter the the fork to two distinct riding positions (45mm or 50mm) without compromising comfort, whatever your wheel size.
The GS1 has clearance for a 700c x 42c or 650b x 48c tyres. So with 700b and 650c wheel choices and a range of tyre sizes you can create the perfect combo for any surface conditions. Note that the rim and tyre variables can affect clearance, so we are happy to support you to find the right options.
1x or 2x Drivetrain
The GS1 is compatible with 1x and 2x Shimano and SRAM options, unlike most competitor brands. Choose your ideal set up and we will build it for you.
The frame features three bottle cage mount options and one 'bento-box' top-tube mount to stash all your necessary gear.
