This is White Industries solution for Pressfit 30 (PF30) bottom bracket systems and incorporates a “thread-together” design that keeps the bearings aligned and prevents creaking. Like our other bottom brackets, it is made by us using U.S. sourced 6061-T6 aluminum and is available in a variety of color options. It comes standard with Enduro stainless steel bearings and can be upgraded to Enduro XD-15 ceramic bearings.

“PF30” is a bottom bracket shell type that was originally designed to use internal bearings (inside the BB shell) with a short 30mm diameter crank spindle. With this thread-together bottom bracket White has located the bearings externally of the BB shell to work specifically with longer 30mm and 29mm crank spindles. 

• Compatible with 46mm inner diameter and 68/73mm wide PF30 BB shells only

• Comes in sizes to fit:

• White Industries MR30 cranks/Etc (30mm spindle)

• SRAM DUB (29mm spindle)

• Installation torque spec is 26-37 ft lbs (35-50 Nm)
