FSA RPM Power Pro Square Taper Bottom Bracket

This unit is designed for frames with a 68mm shell width and English threading, which is the most common standard for road and commuter bikes. If your frame uses a different shell width or Italian threading, this will not be compatible.

This bottom bracket uses the JIS (Japanese Industrial Standard) square taper interface. It is compatible with most standard square taper cranksets, but it will not work with ISO-taper cranks, which are typically found on older high-end European components.

The 118mm spindle length is critical for maintaining your chainline. If you are replacing an existing bottom bracket, you should match the spindle length of your current unit to ensure your front derailleur shifts correctly and your chainrings align properly with the rear cassette.

Yes, you will need a standard splined bottom bracket tool to install the cups securely. Because the bearings are sealed inside the cartridge, you won't need to perform any manual bearing adjustments or greasing during installation.

This model uses industrial sealed cartridge bearings with oversized 3/16-inch balls. These are more durable and better at resisting contamination from water and grit compared to the loose-ball bearing systems found on entry-level bottom brackets.
