Shimano Ultegra SM-BB72-41B PressFit Bottom Bracket

Season:CORE

Brand:Shimano

Code:ISMBB72

The Shimano Ultegra SM-BB72-41B PressFit Bottom Bracket ensures smooth bearings, advanced sealing, and high manufacturing tolerances.

The bottom bracket is a component that usually does its job without making a fuss. Shimano knows how indispensable it is to the drivetrain, which is why they ensure smooth bearings, advanced sealing, and high manufacturing tolerances. With the Ultegra SM-BB72-41B PressFit Bottom Bracket, you are able to press this component right into your frame, working with a Shimano HollowTech crankset and any frame equipped with a BB86 bottom bracket shell. Two steel cartridge bearings are featured with this bottom bracket, and they are pressed into composite cups which increase the outside diameter to 41mm to match the frame's bottom bracket shell. A 1.75mm thick outer-lip provides a positive stop for the cups when they are pressed into place.

  • Superior power transfer and lightweight for efficiency
  • Dura-Ace proven four-arm design with similar stiffness
  • 14g lighter than the SM-BB6700 but maintains the same durability
