Full Speed Ahead Bottom Bracket

This bottom bracket is specifically designed for frames with Italian threading, which typically features a 70mm shell width and a 36mm diameter. Before purchasing, verify that your frame is indeed Italian-threaded, as this is distinct from the more common English (BSA) standard.

This unit is compatible with square taper cranksets that utilize the JIS (Japanese Industrial Standard) interface. If your current crankset uses a different interface, such as Splined or Hollowtech, this bottom bracket will not be compatible.

The double snap seals are designed to create a tighter barrier against environmental contaminants like water, grit, and road grime. This helps prevent premature bearing wear, keeping your drivetrain running smoothly for longer periods between maintenance.

Yes, the spindle length is critical for achieving the correct chainline. You must match this 122.5mm length to the specific requirements of your crankset; using the wrong length can cause shifting issues or prevent the crank arms from clearing your frame.

Yes, the alloy construction is robust and designed to handle the stresses of daily riding. Alloy cups provide a secure, stable interface within the bottom bracket shell while resisting corrosion better than basic steel alternatives.
