The Wheels Manufacturing T47 Inboard ABEC-3 bottom bracket is designed for T47 threaded BB cups, suitable for T47 frames and 24.00mm spindle diameter cranks. These cups feature internal bearings and are typically used in bottom bracket shells with widths wider than 73mm. Machined from aluminum, the cups thread directly into a T47 BB shell, allowing for easy servicing or replacement of the bearings. The bottom bracket includes a sleeve that fits between the cups, providing added protection from dirt and grime, and preventing internal wires and hoses from rubbing on the crank spindle.

This bottom bracket set includes BB cups with bearings, two silicone dust seals, two 0.5mm crank spindle spacers, and two 1.0mm crank spindle spacers. The thoughtful design and high-quality materials ensure smooth performance and longevity, making the Wheels Manufacturing T47 Inboard ABEC-3 bottom bracket a reliable choice for cyclists looking to maintain their bike's performance and protect its components.
