Ride quick.ABOUT THE VENTUM GS1 APEX XPLRShaped 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 SRAM Apex XPLR 1x12-speed electronic groupset and alloy wheels. Complete with a ZIPP Service Course alloy cockpit, it�s an adventure-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.
