SM-BBR60 Bottom Bracket

Product Information

The Shimano SM-BBR60 bottom bracket is a solid choice for road cyclists looking to upgrade or replace their threaded bottom bracket. Engineered with Shimano's HOLLOWTECH II technology, this component offers a great balance of rigidity and pedaling performance, ensuring your power transfer is efficient.

What sets the SM-BBR60 apart is its reduced rotational friction, reportedly up to 50% less than previous models, thanks to advanced sealing technologies. This not only makes for smoother spinning but also enhances durability by providing better protection against the elements. It’s also noticeably lighter, shaving off around 15 grams compared to its predecessor.
