38m deep rims give you that aerodynamic advantage when it counts. The 25mm wide rims give you the ability to run up to a 50mm tire of taking on everything the terrain throws at you. And the G1 spoke provides the Gulo standard in ride quality you will feel with the first pedal stroke.
The Gulo G1 spoke is a triaxially braided composite featuring Ride Smooth Technology(RST). We engineered RST utilizing custom braid angles that consist of a blend of materials, all uniquely chosen for comfort, strength, and stiffness. In developing this spoke, two main goals were at the forefront: lightweight and impact resistance. The G1 spoke was formulated to absorb massive impacts without failing. At the same time, it will retain tension for much longer than traditional steel spokes at 40% of their mass. The G1 spoke remains one of the lightest spokes ever produced while achieving exceptional impact resistance.
Gulo's hubs are the foundation of our system wheels. The Easy Thread Interface (ETI) hub allows the G1 spoke to pull in a straight line, joining the rim as it naturally should, creating less stress and more durability, with a longer lifespan than many more traditional wheels. Our hubs feature our patented "anti-bite" freehub body. With six pawl drivers (alternating in sets) and high-quality steel bearings, the system hub for the Gravel AllTerra Series has 48 points of engagementin a machined 7075 aluminum alloy shell. Easily swap drivers with a couple simple tools.
Varying axle configurations are available, with QR adapters offered for those running classic QR axles.
