Wheel bores are reamed perfectly round and smooth.
Outer hub faces are coned to minimize contact with the axle head.
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 all excess plastic from the underside of the wheel tread and the inside wheel face.
Round and smooth wheels roll faster than standard wheels.
The weight reduction provides a faster start, and improves the balance of the wheel for a smoother ride.
