First, before showing the precision lathing, let's cut to the chase...graphite-coating
Your PRO Speed Wheel (left one) is compared to a stock wheel.
Both are Official BSA wheels.
Notice the shiny coated surface on the left wheel. It is perma-coated with a graphite-moly blend using a secret multi-step process.
The coating will stay on your wheels right through the district race! Graphite-coating reduces friction significantly where the wheel contacts the track.
And there's more...
Speed Increase #2
Graphite-coated Wheel Hub
In addition to reducing track friction, your PRO Speed Wheels decrease friction where the wheel hub rubs against the car.
The hub is finely lathed, then graphite-coated just like the tread. This is the single most important thing you can do to decrease your wheel friction.
Lathing Operations that are done before graphite-coating...
Speed Increase #3
Wheel Tread is "Trued"
What is a "trued" wheel?
Precision lathing "trues" the wheel tread to the axle center line,
meaning the tread is now perfectly concentric with the axle,
giving you perfect precision rotation.
Speed Increase #4
Hubs are coned and squared
Why cone and square the hubs?
Once again, imperfections in the plastic cause friction where the wheel rubs against
the pinewood derby car body, slowing your car down.
The hub is precision lathed to remove wheel mold imperfections while squaring the hub so it rests perfectly against the car body when it hits. If the hub is not squared, the wheel will wobble when it touches the car body making
your car unstable and slower. Reducing friction while making your car run straight increases your derby car speed.
Speed Increase #5
Wheels are Lighter
Why do you want lighter wheels?
Lighter wheels are easier to turn, giving you a
faster start and increased speed
as your derby car goes down the track.
Speed Increase #6
ream the wheel bore
Why ream the wheel bore?
Like the other areas of the wheel, the bore has imperfections and
may not be trued to the rest of the wheel. When the bore is reamed,
your pinewood derby car wheel rotates perfectly about the axle.
Speed Increase #7
Outside wheel rim is trimmed
Why trim the rim?
The rim has imperfections that slow your pinewood derby car whenever the wheel rubs against the center rail.
Trim the rim, reduce friction and increase your speed!
Speed Increase #8
Wheels are Matched as a set
All wheels are not created equal. There are many slight differences between each mold.
To achieve optimal performance, your wheels are matched as a set, giving you perfect balance.
You get all of the above precision lathing,
our secret multi-step graphite-coating
treads and hubs for a friction-free surface
giving you the ultimate speed advantage.

I received my Speed Wheels on Thursday just in time for the derby on Friday. We won 8 out of 9 total races and took first place overall in the speed competition! There were a lot of experienced racers there who couldn't believe how fast our car was in our first derby. My son and I built this car in one night and didn't have the time to get everything perfectly aligned but it still didn't matter. The dual block, axles and Speed Wheels made everything very easy for us. Next year we will start earlier and we will be even faster!!
Alex and I thank you. I don't think he has stopped smiling since Friday...
