The Campagnolo Centaur bottom bracket uses a square taper spindle and three sealed cartridge bearings for smooth, consistent rotation. This English-threaded (68mm) model has a 115.5mm spindle with a hollow axle design and aluminum cups, suiting a range of Campagnolo road groupsets. It forms a secure connection between crankset and frame to support steady power transfer.
This bottom bracket fits Daytona, Racing Triple, Centaur, Veloce, and Mirage components, along with 1993-and-later Athena and pre-1995 Record and Chorus cranksets. The 115.5mm spindle suits triple cranksets paired with 32mm or 35mm seat tubes, and works with 2x or 3x cranksets using an oversized spindle diameter. Its unique taper is not compatible with Shimano cranksets.
