Campagnolo Centaur Cartridge Bottom Bracket

This unit is designed specifically for frames with an Italian-threaded bottom bracket shell, which measures 70mm in width and has an internal diameter of 36mm. Please verify your frame's threading before purchasing, as it will not fit standard English-threaded shells.

This bottom bracket uses the ISO square taper standard. While it works perfectly with Campagnolo cranks, it may not be compatible with JIS (Japanese Industrial Standard) cranksets, which are common on many other brands. Always check your crankset's specific taper requirement to ensure a secure fit.

No, it is designed as a sealed cartridge unit, meaning it is essentially maintenance-free. The three sealed bearings are protected from the elements, so you can focus on riding rather than servicing the bottom bracket.

The use of three sealed cartridge bearings provides extra support for the spindle, which helps distribute loads more evenly. This design results in smoother rotation and increased durability compared to standard two-bearing setups.

This bottom bracket is best suited for classic road bikes or modern builds specifically designed for square taper cranksets. If your frame uses a modern press-fit or external bearing system, this component will not be compatible.
