Zipp CeramicSpeed Bearing Kit

Looking to upgrade your Zipp 77 front hub or 177 freehub(only) bearings? Partnering with CeramicSpeed, Zipp offers this pair of modified 61803 hybrid sealed cartridge bearings to give you the reduced friction and faster, easier rolling speed of high quality ceramic bearings. With measurable savings of 1.5-9 watts (loads of variables), they’re the ultimate complement to the race proven speed of 77/177 hub-equipped rear Zipp Firecrest wheels.

When every watt saved is a watt that matters to you, investing in the lowest resistance hybrid ceramic (ceramic balls and steel races) available will pay off in performance results. The variance in watt savings is dependent on several variables, such as the condition and type of your existing bearings, but without a doubt 1.5w can be the difference between a podium placement or an age group personal best. Zipp and CeramicSpeed also includes a grease syringe for refreshing the grease in your bearings. This is a necessary process for ceramic-equipped sealed cartridge bearings. The grease is a special formulation for these CeramicSpeed balls and the syringe comes preloaded with almost 6ml of grease, which will last through numerous services.
