The Pinnacle Of Chain Technology

Ultra Strong
The ZZZ chain features a revolutionary new side plate profile that more effectively distributes the load onto the side plate. This innovative design gives the 530ZZZ chain an incredible 11,100lb. tensile strength without increasing weight(4.85 lbs. per 100 links). Zero Stretch
EK’s proprietary Zero Stretch Technology (ZST) virtually eliminates initial chain stretch. No chain adjustment is needed in the first 1000km of use.
