HC3z is the ZR02 version of the Wildly popular original HC3 R188 bearing. Sporting the same crown style retainer, this bearing offers incredibly smooth and fast spins with the same tight tolerance as the Si3n4 counterpart. Spin times are above average. Signature is low and feedback is minimal with a "glassy" Zr02 feel. If you liked the HC3, the HC3z will not disappoint!
Cleaning: This bearing can be cleaned in high ISO. An immediate and thorough drying with a hair dryer on cool is highly recommended.
