The Shimano Ultegra SM-BB72-41B Press-Fit Road Bottom Bracket suitable for Ultegra 6800 crankset.  Compatible with frames for the new oversize BB standard (86,5x41mm BB case size).
This SM-BB72-41B PressFit bottom bracket is made to press right into your frame. It will mate your Shimano HollowTech crankset to any frame equipped with a BB86 bottom bracket shell. This bottom bracket also comes with two steel cartridge bearings that are pressed into composite cups. The cups increase the outside diameter of the assembly to 41mm in order to match the frame's bottom bracket shell. There's a 1.75mm thick outer-lip that provides a positive stop for the cups when you press them into place.
