Spin without the drag.
Shimano's new Ultegra SM-BBR60 Bottom Bracket was made with the same high level of precision that you've come to expect from the engineers at Shimano. The silky-smooth steel bearings, advanced sealing, and high manufacturing tolerances make the SM-BBR60 the perfect bottom bracket choice for either your English- or Italian-threaded frame.
The bottom bracket weighs in just around 76 grams, making it close to 15 grams lighter than its predecessor. In addition to the making the bottom bracket smaller and lighter, Shimano says that the design of the BBR60 reduces rotational friction by 50%. This is said to be due to advancements in Shimano's sealing technologies.
The Shimano Ultegra SM-BBR60 Bottom Bracket is available in one size and for either English (68mm) or Italian (70mm) threading.

Refurb Success

I bought this bottom bracket to refurbish a bike as a gift to my little sister. Great price. Solid performance. I've been riding on a Shimano BB for a solid minute and trust it so much to put my lil sis on it. The new rig has allowed her to enjoy cycling so much more. The bracket does the business and she feels more secure and connected while she's on it. Standard installation and no surprises.

This was the best bb upgrade, smooth and quite.. no creaking. Easy to install... I must have about 3000 miles on it with no issues. Would definitely recommend
