Radium Performance

Radium's new F55 Darkstar Motor.

Same 6485 form factor. Runs 10°C cooler. 10% more torque.

Mach One S exclusive — for now.

Two days. Mach One S launches Saturday.

Meet the new Kegel Core SR125.

We've had a lot of requests for Kegel compatibility on the SR125. V3 delivers it.

The reason it took time: standard 22mm bearings weren't designed for the lateral forces a 125mm rubber compound wheel produces.

We solved it with a hybrid bearing seat — 28mm mountainboard-spec on the outside, standard 22mm skate size on the inside.

Full Kegel compatibility, engineered properly.

Fair warning on stock: eskate brands have been placing bulk orders, and we're already running low.

If you've been waiting to run SR125s, now's your moment.
