This is the Ultimate Racing Lightweight +1mm Wheel Hexagon. It is made from T6-7075 aluminum and is anodized in dark gray color. It is intended for Mugen, Associated, Xray, Sworkz, Losi, and Tekno, among others.

Thanks to its design, its weight has been reduced by about 25% compared to the original Mugen.

All edges of the hexagon feature a slope that helps with faster and easier wheel changes.
