Origin8 ISIS Bottom Bracket

This unit is designed for frames with a 68mm shell width and English threading. Please verify your frame's bottom bracket shell measurements before purchasing to ensure a proper fit.

ISIS is a specific spline interface standard for connecting your crank arms to the bottom bracket spindle. You must have an ISIS-compatible crankset to use this bottom bracket; it will not work with square-taper or external bearing cranksets.

The hollow-chromoly spindle is designed to offer a high strength-to-weight ratio. By removing material from the center of the spindle, it reduces overall weight while maintaining the stiffness required for efficient power transfer during your pedal strokes.

The sealed bearings are designed to be low-maintenance, as they are protected from dirt, water, and grime by integrated seals. While they don't require frequent servicing, they should be inspected periodically for smooth rotation and replaced if you notice any play or grinding.

Yes, the robust steel body construction makes this a durable option for various riding styles, including mountain biking. However, ensure that the 108mm spindle length is the correct size for your specific crankset's chainline requirements.
