What started with repurposed road bike wheels has now become a performance-driven focus on aerodynamics and efficiency.
Our G45 Aero Gravel wheels feature wider rims that accommodate larger tires using lower tire pressure which smooths out rough roads and reduces rider fatigue. High-profile rims, combined with improved tire transitions, have also enhanced aerodynamics, giving athletes every edge to ride faster and reach their destination quicker. This shift reflects the growing demand for speed, comfort, and control in the gravel world.
Over 200g lighter than comparable 45mm gravel wheelsets, the G45 delivers faster acceleration and superior control—without compromise.
Produced fro a single piece of aluminium using cutting-edge tehcnology and precision CNC machinery, the Xero Gravity hubs v.2 are optimized for carbon spokes with t-head spoke ends to give instant power transfer while CeramicSpeed bearings ensure reliable performance.

Wider rim that instantly improves you tire profile by over 5%. Giving you better control and comfort with lower pressure, smoothing out rough roads and reducing rider fatigue.
Structurally stronger, straight-pull design reduces stress at the spoke head and hub flange, extending overall lifespan of both the spokes and hub.
Newly developed t-headed spoke end prevents wide carbon spoke from twisting in motion, increasing greater stiffness for direct power transfer.
Carbon aero spokes 5.0mm diameter
The 5mm wide aero carbon spokes are designed for greater aero efficiency and performance.
