The Campagnolo Chorus bottom bracket pairs a hollow chromoly steel spindle with three sealed cartridge bearings, two on the drive side and one on the non-drive side. Removable cups machined from 7000 series aluminum support smooth rotation and long service life, making this a solid option for road cranksets that rely on a traditional square taper interface.
This bottom bracket fits Campagnolo Record or Chorus square taper cranksets from 1995 onward; its taper profile is specific to Campagnolo and is not compatible with Shimano cranks. The shell threads into a 68 mm English BSA frame with a 1.37-inch shell diameter, accepting a 102 mm spindle for correct chainline.
