Radium Performance® SR125 Wheels

The Radium Performance® SR125 wheels were developed to deliver racey urethane-like road feedback with the comfort and grip of a pneumatic wheel.

Why Radium SR125:

• Impressive high speed stability with perfect balance - glassy smooth at 45mph.
• Engineered to carve with an offset core design that enables tight low speed turns.
• Grip level that rivals pneumatic but with more direct, racey handling.
• Compression holes and soft rubber provides plush comfort on and off road.

The SR125 had too much grip for old school skate bearings so we developed the Radium Core system to enable the use of 28mm mountain board size bearings. An added benefit is support for 8, 10 and 12mm axles by using different bearings. 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 finicky shim washers - a significantly lighter and simpler pulley system.

• 125 x 75mm.
  
• Square profile with slightly rounded edges for a smooth grip/slip transition.
• High grip NR/SBR rubber compound with extremely long lifespan.

• 28x8mm bearing seats with 22.2/15.2mm adjustable spacing (requires min 40mm axle length).
  
• Each wheel weighs 770g.
• Price includes 4 wheels + 15.2mm & 22.2mm bearing spacers for 10mm axles.
