The Onyx Vesper rear hub is totally silent and allows you to 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 or for riders over 180lbs/81kg. If you are looking for a DH or E-MTB hub from Onyx, consider the MTB Series.

*IMPORTANT COMPATIBILITY NOTE: Vesper hubs are NOT compatible with e*thirteen cassettes.*

Anodizing: All hub brands we sell offer at least one anodized color, and although they use purpose-built anodizing labs, there can be variations in color due to the nature of the electrochemical process. As such, we cannot guarantee that your hubs will match in color exactly as pictured on our website. If we notice a significant difference in a pair of hubs you order, we will contact you to discuss a resolution. If you have any questions, feel free to .
