ZIPP SUPER-9 61803 Ceramic Bearing #00.1918.183.002

The ZIPP CeramicSpeed ceramic bearing kit for Super-9 hub combines two premium bearing references, one in 61803 size and the other in 61903 size, to cover all contact points of the Super-9 and Sub-9 hub. Developed with CeramicSpeed, these hybrid ceramic ball bearings significantly reduce internal friction compared to standard steel bearings.

The measured gain is between 1.5 and 9 watts per bearing set, depending on the condition and level of the original bearings replaced. This kit comes with a specific grease syringe for optimal installation, ensuring long-term durability and rolling smoothness.
