The threaded bottom bracket is perhaps the gold standard in bottom brackets. Few bottom brackets have the solid reliability of a threaded bottom bracket, and Shimano makes some of the best in the world. The Shimano Ultegra BBR60 Italian Bottom Bracket is Shimano's workhorse bottom bracket, balancing performance with long term durability.

The Shimano Ultegra BBR60 Italian Bottom Bracket is available in both English-threaded BSA 68 mm options as well as an Italian-threaded 70 mm option, perfect for your favorite Pinarello frame.
