PF30 Press-Fit Bottom Bracket Compatibility

Also known as: Press Fit 30, PF30

PF30 presses bearing cups into a 46mm frame bore (68mm road / 73mm MTB), giving a large 30mm spindle clearance without threading the frame. It is effectively a press-fit version of BB30.

A 46mm PF30 bore is roomy enough to adapt down to almost any crank: 30mm native, plus 24mm Shimano, SRAM GXP/DUB and Campagnolo via reducer BBs. Press-fit can be more prone to creak than threaded shells, which is why threaded-into-a-cup PF30 solutions and T47 conversions are popular.

Frequently Asked Questions

Is a PF30 bottom bracket threaded or press-fit?

PF30 is a press-fit standard: the bearing cups press into the frame bore (46mm bore, press-fit nylon/alloy cups). Press-fit saves weight and allows a larger spindle, but demands tight frame tolerances and can be more prone to creaking than a threaded shell.

What shell width does a PF30 frame use?

PF30 frames use a 68mm / 73mm shell (46mm bore, press-fit nylon/alloy cups). Always match your bottom bracket to both the standard and your frame's exact shell width before buying.

Which cranks fit a PF30 frame?

With the right bottom bracket, a PF30 frame can run cranks on several spindle standards. In our catalogue we have PF30 bottom brackets for: 24mm (Shimano Hollowtech II); 30mm (BB30 / PF30 / 386EVO); SRAM GXP (24/22mm); FSA MegaExo (19mm); SRAM DUB (28.99mm); Campagnolo Ultra-Torque (25mm); Campagnolo Power-Torque (25mm). Pick the bottom bracket that matches your crank's spindle, most commonly 30mm (BB30 / PF30 / 386EVO).

How many PF30 bottom brackets and frames are listed?

We currently track 50 PF30 bottom brackets and 11 frames built to the PF30 standard, checked against our compatibility engine.

My PF30 bottom bracket creaks. What can I do?

Press-fit creak usually comes from insufficient preload or a bore that is fractionally out of tolerance. Options include a thread-together (compression) bottom bracket that clamps across the shell, careful greasing/retaining compound on the cups, or (on frames with a ~46mm bore) converting to a threaded T47 bottom bracket for a permanent fix.
