Durable QX-Ring Chains

The DEX Series offers the benefits of a sealed Quadra X-Ring (QX-Ring) chain while keeping budget in mind. Achieved by matching EK’s proven heavy duty chain links with the premium QX-Ring sealing technology.

Quadra X-ring (QX-Ring) is a slim profile chain with 40% less friction than a normal O-Ring chain and 150% better endurance. Used for a variety of SRX2, 420SRX and 428ZVX series chains.
