Lots of people will tell you that ceramic bearings are the way to go for serious cyclists, and we're not here to argue. Ceramics are said to be more spherical, smoother, and made to higher tolerances, so it isn't surprising that ceramic BBs like the FSA 386EVO PF30 is buttery smooth, durable, and fun to ride. Compatible with both BB386 EVO and PF30 shells, this bracket runs sealed ceramic cartridge bearings loaded in special lightweight Ceramic Revolution grease, which will provide almost endless friction-rotation. Installation is easy as pie, and the design will keep you spinning smoothly for years.
