SR125 Wheels

New Radium Core with 28mm bearing seats! Supports 8, 10 and 12mm axles.

Featuring enormous high speed stability and smoothness, impressive low speed turning and pneumatic-like levels of grip while soaking up bumps and delivering a ride feel closer to urethane than pneumatic. Enjoy feeling the road through your feet without feeling the bumps through your bones.

The new Radium Core was developed to allow for the use of 28mm bearings which is a necessity for these wheels to ensure long bearing life. An added benefit is support for 8, 10 and 12mm axles now. The 12 hole Radium Core system features 4 threaded holes and a locating groove, allowing for pulleys that bolt directly to the wheel without the need for support bearings and annoying shim washers - a significantly lighter and simpler pulley system.

We're working with other brands to make Radium Core a new standard wheel system for electric skateboards.
