Zero Stretch Technology
EK’s exclusive Zero Stretch Technology reduces chain stretch to near zero in the first 600 miles (1000km) of use. Not only does this eliminate the nuisance of a 600-mile chain adjustment, but also helps minimize excessive sag throughout the chain’s entire service life. EK Zero Stretch Technology is standard on the 530ZZZ, and optional on the 520RXO and all MVXZ series chains.
