Why We Like The Ultegra SM-BB72-41B PressFit Bottom Bracket

The bottom bracket is a component that usually does its job without making a fuss, and Shimano knows how indispensable it is to our drivetrain, which is why they ensure smooth bearings, advanced sealing, and high manufacturing tolerances. With the Ultegra SM-BB72-41B PressFit Bottom Bracket, we're able to press this component right into our frame, working with our 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're pressed into place.

  • Shimano puts quality first with the SM-BB72-41B Bottom Bracket
  • 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
  • Weighs in at 69 grams for optimal lightness

What do you think about this product?



I am about to receive the Shimano FC-R7000 crankset and my bike is listed as BB30. Is this the correct bb for me?


Would this be considered an Ultegra-Level bottom bracket?
