OneUp Components wanted a lightweight hub, an affordable hub, and a quality, reliable hub. Usually, you can pick two, but they’re delivering all three, and they come in seven colors.

The CNC’d alloy hub shells pack simple but proven tech inside, are rated for any type of bike, from XC to long-travel eMTBs. Here’s how they come together…

The hub shell is machined from 7075 alloy, and it’s easily user-serviceable with a mostly tool-free disassembly, save for bearings…you’ll need a press to replace those and pull the axle out (properly, anyway).

The inner drive ring nested into CNC’d grooves rather than being threaded in. They say this saves weight, allows wider bearing spacing, and makes it simpler to assemble and maintain.

Claimed weight is just 362g for the pair – 142g front and 220g rear (w/ XD freehub). This is lighter than most competing mainstream hubs on the market, at about half the price.

- 8.2º engagement
- Enduro ABEC 5 Bearings
- Double-seal endcaps
- 7 colors
- J-Bend spokes

The endcap’s seals have waterproof grease applied between them and the bearing’s seals, and each hubset comes with a packet of DumondeTech waterproof grease for topping it off.

Repairs should be easy, too. They use common J-Bend spokes, and the build specs are laser etched onto the hub shell for easy reference.
