Description
Prestine PT-6637 PF30 Bottom Bracket

The PT-6637 PF30 bottom bracket is a precision-engineered adapter designed to convert PF30 frames for use with 24mm spindle cranksets, making it fully compatible with Shimano groupsets. Built for riders seeking a reliable and creak-free interface, it delivers smooth, consistent power transfer across road, gravel, and MTB applications.

Manufactured from CNC machined AL6061 aluminium, the cups provide excellent strength while maintaining a lightweight profile. The anodised finish enhances durability and corrosion resistance, ensuring long-term performance in all riding conditions. High-quality sealed cartridge bearings offer low-friction rotation and dependable longevity, helping to keep your drivetrain running efficiently.

Designed around the PF30 standard, this bottom bracket fits frames with a 46mm internal shell diameter and supports both 68mm road and 73mm MTB shell widths. The press-fit design ensures a secure and precise installation, making it a versatile upgrade or replacement solution.
