Now, the ultimate wheel for your BSA race!

Our Pro Ultra Lite Pinewood Derby Speed Wheels are official BSA wheels which are precision machined by DerbyWorx with a CNC (computerized) lathe to within 0.0005 inches for the ultimate in accuracy and thus, maximum performance. To provide you with an awesome set of wheels, DerbyWorx performs the following operations:

The Pro Ultra Lite Speed Wheels are used without any additional preparation. Optionally polish the bore with Bore Polish, then lubricate and race!

Important Note

The lathing operation removes a small amount of tread surface. The serrated edge is intact. The tread reduction is barely visible to the eye, but is measurable with a caliper. If your race restricts the use of lathed wheels, consider using our specialty tools and supplies to prepare a set of raw wheels.
