GPSR Barnes Style Hub
GPSR now offers two different width Barnes style hubs.
The Standard width 4.00” , and the Narrow width 3.10” for front wheels.
Both 4.00 and 3.10 hubs can be used as a front hub, and the 4.00 width hub can also be used as a rear.
The 4.00” hub has provisions for press-in bearings into the hub. This will allow the hub to be used without bolt on style adapters when used in a front wheel configuration.
For rear wheel configuration, the 4.00” hub will require Bolt-On style 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.
Front and Rear
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.
Rear wheels use bolt-on adapters with knock-off nuts to quickly change the sprocket and brake. They attach to the hub using eight(8) machined 5/16 SHCS.
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

We can custom cut the adapters to any width you need
