ACTIVE-RING

The first sub-category of the STREET series chains called Active-ring aims at customers who particularly prefer long durability of the chain transmission. To meet the request the chains of this category similar to the HIGH PERFORMANCE series are provided with Active-rings and patent-protected KSJ bushes.

520 ORMX: This type is offered as a racing version of 520 ORM chain from the O-ring series. Contrary to 520 ORM chain, it differs in static strength and use of the Active-ring for making the joint sealed. The customers appreciate long lifecycle and reduced passive motion resistance. “Golden” outer plates impart highly attractive look of the chain.
