This is a limited-edition version of the popular 19mm roller and its outer plastic rings come in orange color. The 5-spoke rollers are made from lightweight, tough aluminum, and with built-in ball bearings, they provide a smooth ride.
Rollers are used in Mini 4WD machines to enable faster cornering speeds with minimal speed loss. 19mm is the largest roller available, making most Mini 4WD machines as wide as legally permitted using official Tamiya rules.
