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); Campagnolo Ultra-Torque (25mm); SRAM DUB (28.99mm); 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 6 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.
