Overview
The Tamiya Mini 4WD 17mm Aluminum Rollers with Plastic Rings combine lightweight aluminum construction with plastic ring inserts for smooth track wall contact. The 17mm diameter provides a larger contact area than smaller rollers, offering improved stability at high speeds.
The plastic ring design allows the roller to spin freely on its bearing while the outer ring contacts the track wall with low friction. This combination provides excellent speed retention through corners while the aluminum center keeps overall weight low.
