The Shimano Bottom Bracket PressFit 89.5/92mm is designed to deliver smooth, efficient power transfer for modern road, gravel, and mountain bikes that use a PressFit bottom bracket shell. Built around Shimano’s proven reliability, this bottom bracket provides a stable interface between your frame and crankset, helping to reduce friction and improve pedaling efficiency. The PressFit design allows the cups to be pressed directly into the frame, saving weight and enabling wider frame designs while still maintaining stiffness and durability.
Engineered for long-lasting performance, this Shimano bottom bracket uses high-quality sealed bearings to keep out water, dirt, and grit, making it ideal for riders who face varied weather and trail conditions. It is compatible with Shimano Hollowtech II style cranksets designed for 24 mm spindles, making it a versatile choice for many performance-oriented bikes. Whether you are refreshing a worn-out bottom bracket or completing a new build, the PressFit 89.5/92mm unit offers quiet operation, dependable performance, and the low-maintenance durability that Shimano components are known for.
