Introducing new RONDA DRAKE EDITION 2 produced by Ronda Drake, the wife of world renowned professional racer, Adam Drake. The newly designed outer head has improved performance by reducing weight and lowering the center of gravity, adopting two-color anodized aluminum with pink accents, which is her image color, based on black, and two-color printing on the graphic on outer head. Adopting a cover plate with a thrust plate to improve the durability for advantages in the races. The reducer comes standard with 6.5II (for buggy) and 7.5 (for truggy).
