Tamiya 94721 Double Aluminium Rollers - Race Spec  [94721]

Race Tuning with Tamiya 94721 Double Aluminium Rollers

The Tamiya 94721 Double Aluminium Rollers are a handy upgrade for Mini 4WD builders aiming to sharpen handling on technical tracks. The dual roller design uses a 9mm roller below and an 8mm roller above to combine stability with nimble turn-in. Aluminium bodies cut down friction when the car brushes course barriers, helping maintain speed through transitions. They are built to fit both Mini 4WD and Mini 4WD PRO cars so you can experiment across chassis types.

At roughly 0.6g apiece, these rollers are very light and keep added mass to a minimum. The blue colouring also offers a tidy visual upgrade for display or race machines.
