This hubset is robust and fast. Think of it as a high-performance workhorse. The development of the ZR1 involved 58,500km of test riding, part of 3,222 hours of comprehensive testing. That means you can count on this hubset for years of high-performance riding. The ZR1 is based on a system of six pawls in groups of three in offset to increase engagement and keep the hub system light. At any time, there are always three pawls engaging. This design creates a quick engagement feel, with 66 points of engagement.
