Hope BSA24 Bottom Bracket

This bottom bracket is designed for frames with a threaded BSA shell, which is the most common standard. It is compatible with shell widths of 68mm and 73mm.

This unit is specifically designed for cranksets that utilize a 24mm spindle, such as Shimano Hollowtech II and other compatible standards.

The labyrinth seal provides a non-contact barrier that keeps dirt and moisture out of the bearings without adding the friction typically associated with traditional rubber contact seals. This results in a smoother, more efficient pedal stroke, especially in wet or muddy conditions.

Yes, the stainless steel cartridge bearings are replaceable. This allows you to service the unit over time rather than replacing the entire bottom bracket assembly when the bearings eventually wear out.

Absolutely. The combination of machined aluminum cups and high-quality stainless steel bearings is engineered to withstand the grit and harsh weather conditions common in both mountain and gravel riding.
