Pro Inertia Lites BSA Wheels (4)
The Pro Inertia-Lite wheels weigh in at 1.8 g and retain all of the lettering and numbering inside so they will meet many Pack, District and Council Rules.
In order to create the Pro Inertia-Lite wheels Derby Worx starts with Official, Made in the U.S.A. kit wheels and then perform a 5 step process on the wheels hub to straighten and make them perfectly round also correcting and reducing friction on the outer hub faces. Then the wheels are precision machined on a CNC lathe to true the tread and remove excess weight (45%) from the inside of the wheels for quicker starts and faster runs but leave all of the original markings and numbers to meet most pack rule sets. A lot goes into these wheels so you can build a considerably faster derby car.
