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 engagement.in 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.

When weight is paramount, it shouldn’t come at the cost of compliance and durability. Fortunately, with the AllTerra GGA SL, it doesn’t. The 1215g hookless wheelset is astonishingly lightweight yet still ready to handle whatever your ride encounters. With the 25mm internal rim width, you can pick wider tires for your epic adventures where aerodynamics is less critical. When you add the compliance that comes with Gulo’s G-Spoke, you can focus on the next KOM instead of feeling beaten down from the road.

"These wheels are truly fascinating and amazing. The carbon spoke technology is unreal and the looks of them are dreamy. They’re snappy in and out of corners, soak up a ton of vibration at speed and feel great on pavement. Did I mention the gold ferrels?"
