BSA Speed Wheels | Lightly Lathed by Pinewood Pro | Set of 4 | For use on pine derby cars | Faster starts and higher speeds | Derby rule compliant | Track tested

Precision-Tuned: Each of these derby wheels has been lathed in five different areas for a lighter weight, smoother ride, higher speeds, and excellent performance. Faster than the Competition: Lathed treads—both inside and out—means the wheel construction will turn smoothly with less friction, leading to higher speeds down the derby track. Rule-Compliant: We start with the wheels from the official BSA Pinewood Derby car kit, so they comply with most BSA race rules. All BSA markings are visible on the interior and exterior. Reduced Friction: At each of the derby wheel centers, you’ll see coned and squared hubs, which lessens friction against the derby car body. Reduced friction equals greater speed Lightweight Engineering: Overall, Pinewood Pro’s special lathing process makes the wheels 0.2 grams lighter while eliminating imperfections, giving you yet another derby track speed advantage.
