GULO SPOKE
GULO RIMS

The GMD 27 rim is specifically engineered to compliment our G Spoke. With a 27mm internal width, 24-holes, asymmetric drilling, and a 24mm depth, it’s made for down hill, and everything in between. The finish is durable enough to handle the rocks the mountains throw without so much as a scratch.

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), high-quality steel bearings, and has 54 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.

Chad D.

“My GMD 27's are a serious upgrade. What surprised me was how much the wheels improved my ride experience on technical terrain and downhills. They unlocked another level of my ability to unweight the bike and control my lines — I’m fighting less for exact wheel placement. Essentially the wheels have made it easier for me to ride more precisely and have proven to make my overall trail experience smoother and more enjoyable!”
