Ventum GS1 - GRX Di2

ABOUT THE VENTUM GS1 GRX Di2

Shaped by our obsession with speed, the third generation GS1 is our clearest expression of what a gravel bike should be: simple, fast, and focused. 

To make it faster, we increased tire clearance, cut weight, and improved aerodynamics — all without compromising the thing that matters most: handling. 

What didn’t change? The geometry. We kept our proven Ventum Race Geometry — aggressive, with a tucked rear end and stable steering. Fitting big tires — especially in the rear — presents real design challenges. Many brands have compromised handling in the name of clearance. We didn’t. 

This version of the GS1 gravel bike comes with the all-new Shimano GRX Di2 1x12  electronic groupset and ZIPP 303 XPLR SW wheels. Wireless, and with a super-wide range 10-51T cassete the new GRX 1x12-speed setup is the versatile gravel group we've all been waiting for from Shimano. Complete with the Ventum CR5 one-piece gravel cockpit, it’s a race-ready machine. 

Fast, but stable. Snappy, yet predictable. It’s road bike speed, dipped in gravel bike capability. A bike for those driven to go further, faster.
