Product Details

All bottom brackets are not created equal. That's why Shimano bottom brackets outlast almost all others. Superior sealing, ultra-tight manufacturing tolerances and quality bearings combine to make a bottom bracket that rolls freely and never develops play.

This replacement bottom bracket is designed specifically for Shimano hollow-tech cranks. For convenience it comes assembled and greased, all ready for installation.

Bottom bracket cups for Shimano Tiagra FC-4700 FC-4703 Hollowtech II cranksets.
