GULO SPOKE
GULO G-SPOKES

The Gulo G-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 G-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 G-Spoke remains one of the lightest spokes ever produced while achieving exceptional impact resistance.

Hub
GULO HUBS

Gulo's hubs are the foundation of our system wheels. The Easy Thread Interface (ETI) hub allows the G-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 of simple tools.

Varying axle configurations are available, with QR adapters offered for those running classic QR axles.

Road, gravel, trail and everything in between. There's something about riding a super lightweight wheel system, they just feel fast and effortless. The GGX SL is one of the lightest wheelsets on the market and has made itself a staple in our lineup. Tearing up steep road climbs or along chunky gravel, the GGX SL will always leave you with a smile. The hooked bead can handle higher pressures and as always, tubeless ready.

"Put a pair of GGX SL AllTerra wheels on my cx bike with fat road tires. Very, very light - quick acceleration, laterally stiff but weirdly compliant and responsive. CX and gravel tires next for some off-road adventure! The nicest wheels I have ever owned hands down.
