The wheels are sorted by mold number, and any defective wheels are discarded.
Outer hub faces are coned to minimize contact with the axle head.
Wheel bores are reamed and bored perfectly round and smooth.
The wheel tread is lathed with True Track to achieve a perfectly round wheel, a flat tread surface, and a slight radius on the edges to replicate the look of a stock BSA wheel.
The weight of the wheel is reduced by removing plastic from the underside of the wheel tread, and the backside of the wheel face.
Round and smooth wheels roll faster than standard wheels.
Matched mold numbers ensures that the bore diameter and other wheel measurements are identical, maximizing performance.
The weight reduction provides a faster start, and improves the balance of the wheel for a smoother ride.
