    FTC Note: This product is NOT legal for FTC, we recommend our Stealth Wheel.

    Product Overview: 
    This is a 6" diameter wheel with a polycarbonate body and a TPU rubber "HiGrip" tread profile. This wheel features a 77A durometer tread material that is durable with long-life wear characteristics. Use this wheel for great tread life and good drivetrain response. 

    We feel that these wheels are a more durable option for teams' drivetrains. While they provide good traction, they make for a maintenance-free wheel for the average team. Under normal circumstances we feel that these wheels will last most FIRST Robotics Competition teams the entire season. 
    No bearings or hubs are included in this wheel.

    • Diameter: 6 inches
    • Body Material: Polycarbonate, black
    • Tread Material: TPU rubber, 77a durometer

    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 (not included) to this wheel. If this is your choice, then no bearing is needed. Use #10-24x3/4 thread forming screws to fasten a hub to this wheel.

    • If you wish to drive this wheel with a sprocket, then the sprocket needs to be attached to the side of the wheel, and two ball bearingsneed to be pressed into the wheel (one on each side). The ball bearing must have a 1.125" od. For a 1/2" id, use am-0181 or am-0029. For a 3/8" id, use am-0209. Use #10-24x3/4 thread forming screws to fasten the sprocket to the wheel.

    With Bearings:

    • To press bearings into this wheel (for a free spinning wheel or for use with a sprocket), two ball bearings need to be pressed into the wheel (one on each side). The ball bearing must have a 1.125" od. For a 1/2" id, use am-0181 or am-0029. For a 3/8" id, use am-0209.
