Handmade ceramic bearings installed in aluminium cups
When you want to install SRAM or Quarq’s 24/22mm diameter thru-axle crank into a bottom bracket shell measuring 68mm wide and 42mm in diameter, you need CeramicSpeed’s BB30 SRAM GXP bottom bracket.
Every single bearing is hand built in Denmark under clean room conditions. All parts are selected by hand for perfect fit, each bearing is spun by hand multiple times during the building process to ensure that all parts are matched perfectly.
CeramicSpeed balls are smoother, harder and lighter than the standard steel balls which are typically used in bicycle components.
