Ultra Lites BSA Wheels (4) Overview The Pro Ultra-Lite Derby Wheels weigh in at an amazing 1 gram each, and with 100’s of hours of testing on our track – B.S.A. Racing and a League Championships under their belt, you can be assured these are not just any lightened and weakened 1 race wonders. We start with select mold number matched sets and C.N.C. machine them both inside and out to remove the maximum amount of mass from the wheel in all areas for maximum speed, but retain strength and durability. While the exterior of the wheel remains completely stock, all interior markings are removed. They work well with all lubricants (graphite or racing oils) and feature a Reamed and Burnished hub bore for easier alignment and greater speeds, plus both hub faces have been coned for greater friction reduction.
