Regina Chain RX3 Gold 420x134 Professional (Kids bikes and P65's)

RX3 chain features the special Shaped Bushing which eliminates the “barrel” effect that occurs when a standard bushing is assembled. The result is full contact between bushings and pins along the entire length, with a subsequent reduction in specific contact pressure and, hence, reduction wear.
RX3 chain features also Chromed Pins: exceptional pins surface hardness to maximise wear resistance and enhanced pin core strength to guarantee outstanding shock resistance.

Pitch: 420
