Rear Wheel Products





Rear Quick Change Wheel Assembly  :   available in 17”, 18” or 19”.
The rear quick change wheel will arrive completely assembled, laced and trued-up. Available for 32, 36 or 40 hole styles. Includes the rim, quick change hub, 25mm sealed bearings (2), sprocket/disk ccarriers (2), spokes and knock off nuts.

Available in either a 4" wide hub or a 5" wide hub. The benefits of a 5" wide hub produces a stronger rear rim.  The way this works is the wider hub spreads apart the flanges, thus increasing the angle of the spoke to the rim.  This combination provides moer stability and less flex when riding at an angle. The 5" wide hub uses either 5/8" or 3/4" carriers.
Tire, spacers, axle and knock off nut wrench not included.

Quick Change Adapter Kits  only  :
Please click here to go to the Quick Change Adapter Kit and Products Page

Quick Change Adapter Kit is designed to hold primary components in place along the swing arm while the racer removes the rear tire.  Once the tire is removed you may replace it with another tire already setup with quick change adapter components or flip the wheel around (along with the brake disk and sprocket) and replace it in a short amount of time.  By changing the tire around, the rider is given the opportunity to utilize both sides of his tire.

Available for Honda, Yamaha, Kawasaki, Suzuki and KTM

Rear Quick Change Center Hub Assembly  only  :

You can save money by using your own rim. The rear quick change hub is available in either 4" or 5" wide hub (32, 36, & 40spoke hole styles), 25mm sealed bearings (2), sprocket/disk carriers (2) knock-off nuts (2), carrier bolt set and spokes.  

A 5" wide hub produces a stronger rear rim.  The way it works is the wider hub spreads apart the flanges, thus increasing the angle of the spoke to the rim.   This combination provides more stability and less flex when riding at an angle.  The 5" wide hub uses either 5/8" or 3/4" carriers.

We offer quick change hubs with the bearings either in the center hub or in the sprocket/disk carriers   Bearings located inside the carriers versus inside the hub spreads the torque closer to the swing arms, which takes pressure off the axle and bearings. Results in more Straight pressure versus flex pressure due to bearing placement being more inline with the Chain and brake disk.   This creates less swing arm flex. see Sprocket/Disk Carriers below for pictures of the various styles.. .

You also get to choose what style of knock off nuts you prefer. Styles available are standard (2-wing), round with 4-holes (no wings), bath-tub style, Barnes-style (2-wing) and Kennedy-style (3-wings).     see Knock-off Nuts below for pictures of the various styles


Picture #1:   Components that make up the Rear Quick Change Hub Assembly. Shown with standard knock-off nuts (2-wing) and bearings located in the hub.

Picture #2:   Rear Quick Change Hub Assembly with Bath-tub knock-off nuts (no wings) and notice this set-up is pictured with the bearings located in the sprocket/disk carriers. Bearings located inside the carriers versus inside the hub spreads the torque closer to the swing arms, which takes pressure off the axle and bearings. Results in more Straight pressure versus flex pressure due to bearing placement being more inline with the Chain and brake disk.  This creates less swing arm flex.
