Replacement Ceramic Ball Set for Shimano BB-7700 Bottom Brackets

These balls slot into the factory retainer Y1TF98020.
Supplied with 36 balls, enough for each 18 ball retainer.

These can be used inline with the factory Stainless Steel roller bearings. Ceramic upgrade options may be available in the future.

Manufactured as Grade 5 Bearings, these are best suited to a brand new build and minimal lubricant for race day environments. Alternatively, spruce up your current well used set up to optimise the feel of your trusted configuration.
