The Centaur bottom bracket features durable cartridge bearings, light aluminum cups, and a hollow steel axle. Bearings are German made-for-Campy and spin super smooth due to the perfect tolerances. All external parts are treated with a 'black chrome' finish that gives the product a high quality grey polished finish - simply beautiful.
This BB works with most Campy double cranksets that require a square taper spindle and a 111mm spindle. They will also work on some Campagnolo triple cranks being used on frames with an 1 1/8" seat tube. One thing to note is, the taper is Campagnolo specific and will not work on any other brand than Campagnolo.
