FSA gave a clinic on BB30, which is an open-source bottom bracket standard started by Cannondale. It features a 30mm spindle and cartridge bearings that press into a huge bottom bracket shell 68mm wide. Snap rings stop the bearings from proceeding too far inboard, and spacers are available for mountain bikes with 73mm bottom bracket shells. This is the new SRAM RED BB30 crank.
