Specially-modified high-performance Kevlar®-reinforced 183mm-long and 3mm-wide rear drive belt comes standard in XRAY T2 008 EU Rubber -spec Edition.
This belt is very thin and elastic as possible for an extremely effective transmission that saves batteries and eliminates friction. The belt is specially modified - hand ground on a special machine so the belt is as thin as possible, but in such a way that it will still have long life.
To fully enjoy the benefits from these high-performance belts, be sure all the transmission's ball-bearings are absolutely clean and there is no undue drag or friction.
