EK’s Quadra X-ring chains offer the best combination of maximum sealing for a longer life, and minimum friction for maximum performance. EK’s Quadra X-Ring seals have about 50% less friction than conventional O-Ring seals, & since they have more sealing points between the ring and the side plates, it seals better, and lasts about 50% longer than O-Ring chains!
With long life, low drag & high performance, EK’s Quadra X-Ring chains are usually the best option for almost ALL applications - whether high performance or longer life are the main focus.
Price is for a 520 size chain - $44 extra for a 525 size
Available in Standard, Red, Blue & Gold (extra for coloured chains)
