Most riders should replace their bike's bottom bracket every one to two years, but factory brackets are highly susceptible to water damage. So if you ride in wet and muddy areas often, you might want to consider replacing your bottom bracket sooner.
The Shimano Ultegra BBR60 bottom brackets are light and durable, and surprisingly quiet. They were chosen by Bicycling Magazine as the best overall bottom bracket in 2022, and they're the perfect choice for your bike.
Shimano is known for their reliability and durability, and the BBR60's smaller-than-average steel bearings reduce rotational friction by half. In addition, it's significantly lighter than previous Ultegra bottom bracket models.
Shimano Ultegra SM-BBR60 is compatible with both English and Italian threads.
