Our simple design has fewer parts, this reduces weight and improves reliability. The fully machined 7075 aluminum body is super light and strong.

Durable Design.

Premium Enduro™ ABEC 5 cartridge bearings are spaced as wide as possible to reduce wear, reduce side-loading and increase bearing life.

Good Engagement.

We chose to develop a 44T ratchet to strike the best balance between performance and value with improved reliability.


How long is the warranty period on this product? What does it cover?

OneUp Hubs have a 2-year warranty on all components, excluding bearing wear.

How regularly should I service my Hubs?

Hub service intervals vary depending on your riding frequency and the climate. To check if your hubs need servicing, remove the wheel and spin it in your hands by holding the end caps. If it feels or sounds rough and notchy, it's likely time for a service. Alternatively, you can check how your bearings spin by removing the end caps or freehub and feeling them with your finger.

Does the OneUp Hub use a DT Swiss™ ratchet?

OneUp Hubs use a OneUp-specific ratchet and spring. You cannot use a DT Swiss™ Ratchet in a OneUp Hub.

Will OneUp's SRAM XD® freehub work with my SRAM XDr® cassette?

Yes, our XD® Driver is compatible with both SRAM XD® and XDr® cassettes. For SRAM XDr® cassettes, simply remove the pre-installed 1.85mm spacer.

Why do OneUp Hubs use a machined drive ring over a threaded option?

CNC Machining the drive ring directly into the hubshell eliminates a common failure point, where a threaded steel drive ring can strip and tear the threads out of the hubshell, while also saving weight.

Where are & how to I read the hub dimensions to measure spoke length?

The Hub dimensions are on the product pages and lasered onto the center of the hubs.

PCD stands for Pitch Circle Diameter and refers to the distance between opposing spoke holes on the hub flanges (from the center of the hole).

Flange Dist refers to the distance from the center of the flange to the center point of the hub.

L stands for Left & R stands for right.

These four measurements, along with your hub spacing (110 or 148mm) and the ERD of your rim is all you need to measure spoke length. Please use your preferred spoke calculator to complete the measurement!
