HiGrip wheels provide superior traction for robot movement. HiGrip wheels feature an aggressive tread pattern providing maximum transfer of gearbox power to the ground. A robust polycarbonate core means these wheels are up to the challenge for high impact and speed applications. Varying durometers mean you can choose just how grippy these wheels can be. White or 77A durometer HiGrip wheels have a long life and provide good traction. Black or 60A durometer HiGrip wheels have an intermediate life and higher grip than white. Blue or 60A durometer HiGrip wheels provide the most traction and will wear quickly as a result. The bolt pattern and bore of these wheels allow for convenient bearing placement and easy attachment to other motion parts such as sprockets and pulleys.
