NOX Composites Carbon Rims

NOX Composites carbon rims are engineered for riders looking for the ideal balance of low weight, stiffness, durability, and precise handling. Designed with performance-driven carbon construction, NOX offers rim options suited for everything from lightweight XC and trail builds to aggressive all-mountain and enduro riding.

NOX rims feature an asymmetric rim profile designed to improve spoke bracing angles and create more balanced spoke tension between each side of the wheel. The result is a stronger, stiffer, and more reliable wheel build. Their UniWeave™ carbon construction combines different composite materials to optimize strength while keeping weight low.

Depending on the model, NOX rims also incorporate their reinforced RockGuard™ or RockGuard HL™ bead technology to improve resistance against impacts and rock strikes. The Anti-Burp Bump™ helps improve tubeless tire retention and reduces the likelihood of air loss during aggressive cornering and hard riding.

With multiple widths and models available, you can select the NOX rim that best matches your riding style and terrain, then pair it with your choice of hubs, spokes, and nipples to create a completely custom wheelset.

Onyx Racing Hubs

Onyx Racing hubs deliver a completely different riding experience with instantaneous engagement, exceptionally smooth rolling, and virtually silent coasting. Designed for riders who want immediate power transfer without the noise or backlash of a traditional ratchet-style hub, Onyx hubs are a premium choice for your custom wheel build.

At the heart of every Onyx rear hub is their patented sprag clutch engagement system. Instead of using conventional pawls and ratchet teeth, the sprag clutch engages immediately when torque is applied, providing infinite points of engagement with zero-degree engagement. The moment you put power into the pedals, the hub responds.

When you stop pedaling, the system freewheels almost silently. With no pawls clicking across ratchet teeth, you get an incredibly quiet ride that lets you hear your tires, suspension, and the trail beneath you.

Onyx hubs also utilize premium-grade bearings designed for low rolling resistance and smooth performance. Their rear hub designs separate drive forces from axle loads to further reduce drag and promote long-term bearing performance.

For mountain bike builds, Onyx offers options ranging from the lightweight Vesper, designed primarily for XC and trail pedal bikes, to the more robust Classic platform for demanding applications, heavier riders, bikepacking, tandems, and e-bikes.

Key Features

• Instantaneous, zero-degree engagement
• Infinite points of engagement
• Patented Onyx sprag clutch technology
• Virtually silent freewheeling
• Minimal drivetrain backlash
• Premium-grade bearings for smooth, low-drag performance
• Strong, serviceable hub construction
• Multiple axle, drivetrain, spoke-count, and brake configurations available
• Options for XC, trail, enduro, e-bike, gravel, road, BMX, and other applications

Choose your Onyx hub configuration to build an exceptionally smooth, responsive, and quiet custom wheelset.
