Shimano Acera BB-ES300 Octalink Bottom Bracket

The Shimano Acera BB-ES300 Octalink bottom bracket is specifically designed for mountain biking and touring bikes, providing a sturdy and reliable foundation for your ride. Its compatibility with 8-speed gearing ensures smooth and efficient performance across a range of terrains.

Lightweight Design: One of the key upgrades in the BB-ES300 model is its weight reduction. Compared to its predecessor, the BB-ES25, this bottom bracket offers a significant weight saving of up to 25 grams, contributing to better overall bike performance without compromising on durability.

Compatibility: This bottom bracket is designed to fit MTB and touring cranks with a BSA bottom bracket shell width of 68 or 73 mm. However, it is important to note that it is not compatible with E-Type or chain case systems, making it best suited for riders who prioritize simplicity and performance.

Durable Construction: The Octalink system ensures that the crank arms are securely fastened to the bottom bracket, minimizing movement and enhancing overall pedaling efficiency. Shimano's focus on durability means this bottom bracket will withstand the rigors of challenging off-road and touring conditions.

It’s a great choice for riders looking for a cost-effective upgrade or replacement for their existing bottom bracket, offering Shimano's trusted performance at an affordable price.
