The Onyx Vesper hub helps you tame the gnarliest trails on the mountain or blaze your own.

Onyx hubs transfer the precise amount of torque you want to the ground when you need it. Nasty climbs on boulders and rock require just the right amount of instantaneous power but only at your command. There is no substitute for absolute control of your machine.

Listen carefully. Only the sound of the wind in your face separates you from the mountain. Enjoy the music of nature unfettered by the rancorous clicking of pawls. Onyx’s patented sprag clutch design removes the ratcheting noise of traditional hubs.

Enter the Vesper! The Vesper is the next level of innovation from Onyx. Lace up your favorite rim and get ready to ride!

Vesper Hubs are not recommended for Downhill or E-MTB use. If you are looking for a DH or E-MTB hub from Onyx, consider the MTB Series.
