Our standard Olympic 8:1 Cunningham system, but better! Now spliced with 29mm Harken Zircon blocks. At the core of the Zircon performance are industrial ceramic ball bearings mounted inside caged races. The cages keep these bearings separated so they don't bunch, touch, and stop each other. The result is the most efficient small boat block Harken has ever made.
