FingerTech Foam Wheels (pair)

Replacement Foam Wheels in varies sizes. Sold in Pairs. Work great for the the Viper Combat Robot Kit. Foam wheels effectively protect delicate gearmotors from damage caused by impact. Unlike hard wheels, which can break and immobilize your robot, foam wheels tend to only tear or lose a chunk when hit. After mounting them on your hub, it is important to spin and sand the wheel to ensure it is perfectly balanced. Hubs NOT included.  Pairing the foam tires with these Twist Hubs give you a shock-absorbing, high-traction solution for transferring power to the ground. 10mm bore for a snug stretch-fit.
