4 in. Stealth Wheel, 1/2 in. Hex Bore, 80A Durometer

The inside black portion of this wheel is made from molded polycarbonate plastic. The outer tread is TPU (thermoplastic polyurethane). This robust but lightweight wheel provides good traction on carpet and soft tiles. The Stealth wheels are the perfect wheel for intakes and other auxiliary robot mechanisms. The bore of this wheel is available in many bores and durometers. 4" Stealth Wheels feature a bolt pattern on a 1.875" bolt circle for mounting sprockets, hubs, and gears. 8mm bore Stealth Wheels feature a bolt pattern found in most common FIRST Tech Challenge building systems. The grippiest of our wheels, the 35A green wheels should not be used as drive wheels and only for mechanisms and intakes.
