Shimano SM-BB72 Press-Fit Bottom Bracket

The Shimano SM-BB72-41B is a high-quality Press Fit bottom bracket specifically designed for road bikes. Thanks to the proven Hollowtech II technology, this bottom bracket offers an optimal balance between stiffness and low weight, resulting in efficient power transfer with every pedal stroke. This bottom bracket is the standard choice for Shimano Ultegra series and is compatible with frames requiring a bottom bracket shell width of 86.5 mm.

The durability of the SM-BB72 is ensured by the use of advanced seals. These prevent dirt, dust, and moisture from entering the bearings, significantly extending their lifespan, even under challenging weather conditions. The bearing cups are made from reinforced polymer material, which not only reduces weight but also ensures a precise fit in the frame and reduces the chance of creaking noises.

Installation of this bottom bracket is straightforward for mechanics who have the correct Press Fit tools. Due to the small ball bearings, the crank rotates smoothly with minimal friction. Whether you are an avid cyclist looking to upgrade your current bottom bracket or building a new frame, the Shimano SM-BB72 delivers the reliability and performance you expect from a market leader.
