Bottom bracket PF30A

 


bb_standards_pf30a_exploded

Cannondale's PF30a bottom bracket system uses a 73mm wide shell and a 30mm diameter crank spindle. The frame's bottom bracket shell itself is not threaded, instead the bottom bracket cups press directly into the frame. PF30a frame shell inner diameter is 46mm. The PF30a is similar to the PF30 standard, but the frame BB shell is 5mm wider on the non-drive side. PF30a 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

 
Specifications:
Frame shell width: 73mm 
Frame shell ID: 46mm.
Two 6806 bearings (42mm OD, 30mm ID) pressed in cups
