Arrowmax have introduced new molded pinion gears in 48 and 64 pitch. Using the anti-slip golden aluminum hub and high efficient anti wear plastic, the molded lightweight design has been tested on tracks to ensure that they can resist withstand abuses in both On and Off-road uses. Its design saves weight, which allows to reduce rotational mass for quicker acceleration and braking. Both 48 and 64 pitch are available in 25T to 40T sizes and in 34T to 70T sizes respectively.
