This is the ultimate BSA racing wheel where internal mods are not frowned on.  Every area of this official BSA wheel has been treated and machined so all dimensions are perfect and ready to race. In addition to all of the modifications of our lathed wheels, the hub is reamed straight and the inside of this wheel is totally re-worked with special tooling for the most possible weight removal but still retaining durability. This wheel is machined within a .0005” tolerance and only weighs 1 gram.

This wheel should be legal in races
that specify any of the following:

• Wheels must not be peaked, ‘H’ed, humped, tapered, or narrowed.
• Wheels may not be tapered or rounded.
• Wheels may not be tapered or re-formed so as to reduce the footprint of the wheel against the track surface.
• The wheel diameter cannot be reduced past the ridge (rippled) edge and the ridge (rippled) edge must remain intact on the entire wheel.

This wheel would be illegal in races that
prohibit modifying the inside of the wheel..
