This bicycle bottom bracket is a reliable drivetrain component built for smooth, long-lasting performance. It features a square-taper axle measuring 113 mm, paired with durable BSA threads that fit a 68 mm frame shell. The coated axle comes with lock bolts for a secure installation, while the black steel body and threads keep the unit strong and resistant to wear.
A sealing ring helps protect the internals from dirt and moisture, supporting reliable operation over time. Compatible with SHIMANO 89432 and 89418, it makes a straightforward replacement or upgrade for many builds.
