The Shimano Dura-Ace BB-R9100 Bottom Bracket is a great representation of Hollowtech II technology and features smaller, lightweight bearings and an advanced seal construction for smoother rotation and increased durability. The driveside (right) crankarm and the bottom bracket spindle are an integrated unit and the bearings are placed outside of the bottom bracket shell for better weight distribution and more stability. Connecting the crankset to the bike in the engine room of your bike’s chainset, the Shimano R-9100 Bottom Bracket allows the crankset to rotate freely and helps to boost your cycling efficiency. If supreme-quality components are a priority on your bike, then make Shimano your only go-to-brand for premium workmanship, long-life product reliability and unsurpassed on-the-bike performance.
