PLM's flagship bearing oil
It will overturn the "common sense" you thought you knew.

Most bearing oils are judged one way: flick the roller, watch it spin, and see how long it keeps going with no load at all. It's a satisfying test. It's also measuring the wrong thing.

A roller spinning freely with no load is really just showing off its own moment of inertia — a property of its mass and size, not the oil inside it. Even bone dry, a larger roller will out-spin a smaller one. That's physics, not lubrication.

On an actual course, a roller is never free-spinning. Every corner, every wall contact puts real load on the bearing. That's the moment that actually matters — and it's the moment GALILEO was built for.

THE TEST
We measured motor current draw (a direct indicator of rolling resistance) with a load hung from the roller to simulate wall-contact force in a corner, comparing a dry bearing against GALILEO on the same roller.

Test rig: PowerDash motor, 3.0V

No load: no measurable difference between dry and GALILEO — exactly as intended. This isn't the condition we're optimizing for.

50g load: roughly 16% lower current draw than dry
100g load: roughly 12% lower
200g load: roughly 6% lower

Even as the load increases, GALILEO keeps drawing less current than a dry bearing — meaning the oil film is holding under pressure, not breaking down. Less resistance under load also means less strain on your motor and battery: power you get back for acceleration and top speed.

WHY "GALILEO"
The name is a nod to the man who looked past what the world was certain it could see, and pointed to what was actually happening underneath. GALILEO is built on the same idea: don't chase the number that looks good doing nothing. Design for the moment it actually counts.

GALILEO. And yet, it turns.
