Pro Inertia Lite BSA Wheels

These Derby Worx Pro Inertia-Lite Pinewood Derby Wheels are the official NEW Style BSA wheels that weigh in at only 1.8 grams and retain all of the lettering and numbering inside so they will meet most Pack, District and Council Rules. These wheels are much faster than stock BSA wheels. These wheels can be raced without any additional preparation.

These are the NEW style wheels.  The new wheels are much faster than the older style wheels still in circulation. Set of four wheels.

What does this do for your car?

• Round and smooth wheels roll much faster than standard wheels
• Weight reduction provides a faster start because of low start up inertia
• Weight reduction improves the balance of the wheel for a stable and faster ride
• Beveled hub reduces the rubbing and braking when the wheel hub contacts the car body
• These wheels will make your car much faster

Note: Lighter wheels are only one of many factors that make a fast car.  Light wheels alone may not improve your speeds.  In addition to light wheels you must also have adequate lubrication, alignment and weight placement.

Not all BSA pack rules permit these Inertia-Lite wheels.  Please check your local rules to see what wheels are permitted.
