These are 5-spoke rollers made of aluminum and utilize a red plastic outer ring.
Aluminum rollers are an upgrade part for your Mini 4WD racing machine. They greatly help keep your chassis from flying off the track while maintaining speed. This specific set has a circumference of 19mm which is the largest available for Tamiya’s cars, while giving your chassis the widest stance possible under Mini 4WD regulations. The machined aluminum roller is lightweight and contains ball bearings for the smoothest operation possible. The attached plastic rings have less drag compared to rubber O-rings included in other aluminum roller sets which in turn will help maintain momentum.
• 5-Spoke Aluminum Rollers x2
