1. Shot-peened alloy steel side plates for high tensile strength and maximum impact load resistance
2. Chamfered inner links to reduce the chance of chain derailment
3. Extended bushings to reduce friction between outer and inner link plates, maixmising power output
4. Chromised bearing pins for excellent resistance to wear
5. Most perfectly matched chain for chain wheels allowing maximum power at the rear wheel.This also extends the life of both the chain and chain wheels
