Origin8 Revolvr Outboard BB

This bottom bracket is designed for standard threaded frames with a 1.37" x 24T English thread. It is compatible with both 68mm and 73mm shell widths, making it a versatile choice for most mountain and road bikes using this common standard.

This bottom bracket uses an HT2 (Hollowtech II) spindle interface. It is compatible with cranksets that utilize a 24mm spindle diameter, which is the standard for many Shimano and compatible aftermarket cranksets.

Yes, the Revolvr features double-sealed, replaceable bearings. This design allows you to swap out the bearings when they eventually wear out, rather than replacing the entire bottom bracket unit, which helps extend the life of the component.

No, the kit comes with the necessary spacers to accommodate different shell widths and fine-tune your chainline. You should have everything you need in the box to achieve the correct alignment for your specific drivetrain setup.

The cups are made from CNC-machined AL6061 aluminum and feature an anodized finish, which provides excellent resistance against corrosion and the elements. Combined with the double-sealed bearings, it is built to handle regular exposure to moisture and grit.
