Wheels Mfg PF30-Outboard A/C BB 30mm
Description
By popular demand, we've added this PF30 with outboard bearing BB for use with 30mm spindle cranksets when used in PF30 frames. A great choice for use with RaceFace Cinch cranks. The two machined aluminum cups thread together keeping the bottom bracket stable in the frame, increasing bearing life, and simplifying maintenance. This means no more creaking, smoother operation, longer bearing life, and really quick bearing replacement. In Angular Contact (A/C) bearings, ALL balls are engaged and spread the force over a larger surface area, to decrease friction and minimize wear.
** Note: Spindle length must be 103mm or longer when used in a 68mm wide shell, 108mm or longer when used in a 73mm wide shell.
Bearings: Enduro Angular contact
Bottom Bracket/Frame Interface: PF30, Specialized Carbon OSBB*
Bottom Bracket Shell Width: 61mm* to 83mm
Bottom Bracket Shell I.D.: 46mm
Over Bearing Width: 89mm in 68mm wide shell
Crank Spindle Diameter: 30mm
Tool Pattern: 48.5mm x 16 notch
* Specialized Carbon OSBB with 61mm shell width will need additional 3.5mm cup spacers.
