Overview
Bottom Bracket Shimano BB-ES300 Octalink 73mm BSA
The Shimano BB-ES300 is a durable bottom bracket designed for Octalink cranksets. Its round hollow axle and multi-tooth interface create a strong and rigid connection between the crankset and bottom bracket.
Suitable for frames with BSA threading and a 73 mm bottom bracket shell width. The 8-splined Octalink interface delivers significantly improved power transfer compared to conventional square taper systems.
Increased stiffness and optimized load distribution result in smooth rotation, precise crank performance and long service life, even under demanding riding conditions.
