Barnes Style Hub


GPSR Barnes Style Hub
Can be used as a front or rear hub.

Use without hub adapters when used in a front wheel.
For rear wheels, use Bolt-On Quick Change Adaptors.

Mix and match adapter widths to build a custom hub assembly. Adapters will have the bearings pre-installed so all you have to do is bolt it together. Choose from raw aluminum or black anodized finish.

Front and Rear

Ceramic Bearings
For reduced friction, optional ceramic bearings are available.

All hubs feature wheel spacers that capture the hub’s floating center spacer, holding it in place when the axle is removed and installed.

Choose from raw aluminum or black anodized finish.


The front hub does not require adapters. Comes complete with spacers and bearings installed.

  • 4″ Wide


Rear wheels use bolt-on adapters with knock-off nuts to quickly change the sprocket and brake. They attach to the hub using 8 machined bolts. Bearings can be installed outboard in the adapter, or old school in the hub.

Rear with Quick Change Bolt-On Adapters
Mix and match widths to achieve the setup you need. Our adapters are precisely machined to save weight while maintaining strength.

Hub width is 4”. Add a right and left adapter to get the proper overall width for your bike. Standard adapter widths are:

  • 1.125” Wide
  • 1.250” Wide
  • 1.625” Wide
  • 2.0” Wide

We can custom cut the adapters to any width you need
