    This is the 8 in. SmoothGrip wheel. In 2010, the Gray 80A Durometer version was provided in the FRC Kit of Parts under the name "FIRST Wheel". No bearings are included.


    New for 2021, you can now select a Blue 50A Durometer for maximum traction, or a Black 60A Durometer option.

    Usage With Axle and Hub:


    • If you wish to drive this wheel with an axle and hub, you can pick your hub by fitting any of the AndyMark hubs to this wheel. Hubs are not included with this wheel. If this is your choice, then no bearing is needed. To install a hub onto this wheel, use #10-24x3/4 thread forming screws.
