KM H-K1 EvoII two speed steel shaft
KM Racing introduce this two speed steel shaft for the H-K1 EvoII 1/10th on-road chassis. Being of a super lightweight design with a 4mm centre hole the shaft is hardened for increased durability while the low weight of only 12.5g makes for less rotating mass of the drive train.
