Introducing the World's Lightest Ti Ceramic Bottom Bracket for BB386/392 frames and Shimano cranksets

 

FRAME FIT:

  • BB386 EVO frame (46x86.5mm)
  • BB392 EVO frame (46x92mm)

 

CRANKSET FIT:

BB386 is a SRAM-developed version of the BB30 system where the right and left bearings are housed in plastic cups, which are in turn pressed into the frame. The frame's bottom bracket shell itself is not threaded, and has an inner diameter of 46mm. The BB386 system uses thin spacers and/or a wave washer between the bearings and the crank arms to take up any slack and micro-adjust the chainline of the crank.
