Onyx Racing Vesper Hub

Unlike traditional hubs that use spring-loaded pawls to click into place, the Onyx Vesper uses a sprag clutch system. This allows for instant engagement the moment you pedal and completely silent operation when coasting, eliminating the mechanical clicking sound found in most other hubs.

The Vesper is highly versatile and supports a wide range of axle standards, including 135/12, 142/12, 135 QR, 148/12 Boost, 150/12, and 157/12. You should verify your frame's specific spacing before purchasing to ensure a proper fit.

Yes, the Vesper is designed to be compatible with major cassette body standards, including Shimano HG, MicroSpline, SRAM XD, and Campagnolo. Ensure you select the correct driver option that matches your specific cassette type.

The adjustable preload and side load allow you to fine-tune the hub's bearing performance. This ensures the hub spins smoothly while eliminating any unwanted play, which helps extend the lifespan of the bearings and maintains consistent handling.

Absolutely. The Vesper is built with a durable 7075 aluminum shell and titanium hardware, making it robust enough to handle the rigorous demands of both mountain biking and downhill disciplines.
