Ventum Bikes Will be arriving December 2025
Lighter. Simpler. Sharper. The GS1 GRX Di2 2x12 gravel bike is built for one thing — speed. In gravel racing, speed is a constantly evolving equation. The latest generation of the GS1 meets this challenge with increased tyre clearance up to 700x56c in the front and 700x50c in the rear when paired with Shimano's super reliable 2x12-speed GRX Di2 drivetrain. A lighter, stiffer frame, and an all-new aerodynamic front end.
All anchored by on Ventum's signature Race Geometry, a geo trusted by some of the world’s top gravel racers. Fast, but stable. Snappy, but predictable. It’s road bike speed dipped in gravel bike capability. The perfect choice for those driven to go further, faster. Don’t just ride. Ride quick.
An All-New Front End
Taking cues from the new Tempus TT bike, an hourglass head tube utilizes functional airfoils to smooth airflow over rider and bike. Because in modern gravel racing, aero matters.
Ventum Race Geometry
The GS1’s geometry is something Ventum hold near and dear to there hearts at Ventum. Adored by pro riders and obsessed over by engineers, it’s quick in corners yet wonderfully predictable and stable at high speeds over variable terrain.
For Tyres, Bigger Is Better
The GS1 takes up to 700x56c tyres in the front and *700x45c tyres in the rear plenty big for today’s knobbier, fatter gravel tyres. *Tyre clearance on 2x drivetrains is limited to 700x45c.
