Description

– EK 520 SRX2 with QX-ring seal – up to ~40% less friction than comparable O-rings
– Sized for 600-750cc sport, naked and sport-touring road bikes
– Long service life with minimal maintenance
– Steel finish

EK’s 520 SRX2 is the QX-ring step above the basic X-rings – the four-lobe seal geometry cuts running friction sharply and stretches service life. Ideal for 600-750cc road bikes where the rider wants a sealed chain that doesn’t sap performance.
