Description
The Shimano SM-BB71-41 is a high-quality Press-Fit Bottom Bracket designed specifically for mountain bikes (MTB) and road bikes. It is engineered to work with Shimano HollowTech II cranksets, offering exceptional performance, durability, and ease of installation. Below are the product details, features, and specifications:
Product Details:The SM-BB71-41 is a press-fit bottom bracket designed for frames with a 41 mm shell diameter. This component is compatible with MTB cranks and provides a smooth and reliable pedaling experience, reducing the risk of frame noise and wear.
Features:- Press-Fit Design: Fits 41 mm diameter bottom bracket shells, ensuring a tight, secure fit.

In addition to its compatibility with MTB frames, the Shimano SM-BB71-41 bottom bracket will also technically work with road bike frames that use 86mm shells. However, the inner cable sleeve cover provided will not fit properly in this setup. To address this, you would need to either run the bottom bracket without the inner sleeve cover or reuse an existing cover from a previous setup.
This bottom bracket provides a great balance of weight, stiffness, and sealing performance, making it a popular choice for cyclists who need reliable, long-lasting components
