Silent, stealthy and quick engaging. Onyx’s revolutionary sprag clutch is the fastest rolling hub on the market. Their freehub is completely silent when coasting, and engages instantly when you drop the hammer. Onyx offers two versions of their hub. The lightweight Vesper which utilizes a smaller clutch and is best suited for XC and general trail riding , and the classic Onyx hub which is burlier and suited for heavier riders, or DH/E-bike applications. The 27.5″ TR37 laced to a Vesper builds up a 1815g wheelset with Sapim D-Lights, while the 29″ version comes in at 1865g. Wheelsets built with the Onyx Classic will weigh in around 1915g for the 27.5″ build, and 1965g for the 29″. Available in any colour imaginable, you can customize your wheelset to your liking. All NOBL wheelsets come taped with valves and ready to go! Simply throw your tires on with sealant and you’re set!
