Specially-modified high-performance 351mm-long and 3mm-wide drive belt. This belt is very thin and elastic as possible for an extremely effective transmission that dramatically reduces friction and helps to reduce battery draw. The belt is specially hand ground on a special machine for minimal thickness and flexibility, without affecting lifespan.
To fully enjoy the benefits from these high-performance belts, be sure all transmission ball-bearings are absolutely clean to reduce drag and friction.
