Tamiya 94721 Dual Aluminium Roller Set for Mini 4WD  [94721]

Track Ready Tamiya 94721 Dual Aluminium Rollers

The Tamiya 94721 Dual Aluminium Rollers are a compact upgrade aimed at Mini 4WD enthusiasts who want crisper handling on race layouts. The lower 9mm roller and upper 8mm roller work together to maintain speed on straights while improving corner control. Aluminium construction helps reduce drag when the car contacts track barriers, smoothing lap times. These rollers suit both Mini 4WD and Mini 4WD PRO chassis so you can test them across different setups.

Each roller weighs about 0.6g, keeping added weight negligible. The blue finish gives a clean look that complements many builds.
