‘Tough’ Hub


GPSR ‘Tough’ Hub
Bigger, Stronger, Lighter.

The Tough Hub’s oversized design strengthens the flange area and weighs less than our traditional Barnes Style hub.

It’s 3 in 1 function allows use as a front hub, rear hub with Bolt-On Quick Change Adapters, or rear hub with Pull-Thru Reversible Quick Change Adapters.

Tough Hubs are sold complete. Includes: hub, 2 adapters, 2 bearings (installed), 2 knock-off nuts (rear only), spacers, and hardware.

So Many Choices. . . Pick The Setup That Is Right For You.
The Tough Hub can do it all: standard front, TT front, quick change rear or reversible quick change rear.

Front and Rear


Hub without adapters is 4” wide. Spoke flange is 5” diameter.

Hub Adapters

All Tough Hubs include adapters with pre-installed bearings. Adapters vary in width from  .25” – 2.0” wide each, per side.

Ceramic Bearings

For reduced friction, optional ceramic bearings are available.


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


Our front adapters attach to the hub using eight(8) SHCS (Socket Head Cap Screws) bolts and come with center spacer and bearings already installed.

Standard Front
4” wide hub. Total width including 2 standard adapters is 4.5”

  • Universal Front


Rear with Quick Change Bolt-On Adapters
Our Tough Hub’s quick change bolt-on adapters are attached with eight(8) 5/16-18 machined SHCS(Socket Head Cap Screws) PLUS 4 pressed in steel pins to handle the increased loads from today’s higher output race bikes. This is much stronger than traditional 6 or 8 bolt designs.

Features knock-off nuts for quick changing of the sprocket and brake. Our adapters are precisely machined to save weight while maintaining strength. Custom widths are available.

  • 6.25” Wide with Symmetrical Adapters
  • 6.50” Wide with Symmetrical Adapters
  • 7.25” Wide with Symmetrical Adapters
  • 8.0” Wide with Symmetrical Adapters
  • Honda CRF450
  • Yamaha YZF450

Rear with Quick Change Pull-Thru Reversible Adapters
The reversible design allows turning over the rear tire without removing it from the rim. Instead of bolting to the hub, pull-thru adapters attach to the hub using one of the knock-off nuts. Unscrew one knock-off nut and in less than 30 seconds you can reverse the direction of the tire. This type of adapter setup is commonly used on DTX Bikes.

Reversible adapters are only recommended for asymmetrical rear wheel setups where the right and left side are different widths. If the adapters are the same width, we recommend using bolt-on adapters.

Combine right and left widths to achieve the proper setup. Adapters include knock-off nuts to quickly change sprockets and disc brakes.
