This high-performance wheel features a silicone rubber molded wheel on a lathe-machined aluminum hub. The hub is narrower than the standard version, as the set-screw hole has been removed from the collar (which was then removed), and moved to the main part of the hub, under the wheel itself.

This makes for a narrower wheel for tighter installations. We’ve even found we can place the gearmotor gearhead in the hub cavity itself for very tight installations. It’s ideal for mini-sumo, like our 1st place finishing Strong Bad!!
