Nitro 80 Skate roller skis are purpose-built for junior skiers. The roller ski frame is designed around 24x80mm junior sized wheels that feature a lower weight and flatter profile compared to standard 24x100mm wheels.

Pro-track classic wheels roll much straighter than standard classic wheels. A soft blue rubber is sandwiched between two sections of harder skate wheel rubber.

Rundle skate roller ski wheels are made by the same manufacturer that makes Swenor, Fischer, and IDT roller ski wheels.
