BB386 EVO Bottom Bracket Compatibility

Also known as: BB386 EVO, 386 EVO, BB386

BB386 EVO combines the wide 86.5mm shell of BB86 with the large 46mm bore of PF30, giving room for a full-length 30mm spindle across the widest shell. It aims to be the most adaptable press-fit standard.

That 46mm × 86.5mm bore adapts to virtually every crank spindle: 30mm native, plus 24mm Shimano, SRAM GXP/DUB and Campagnolo through the right bottom bracket.

Frequently Asked Questions

Is a BB386EVO bottom bracket threaded or press-fit?

BB386EVO is a press-fit standard: the bearing cups press into the frame bore (46mm bore, 86.5mm wide, press-fit 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 BB386EVO frame use?

BB386EVO frames use a 86.5mm shell (46mm bore, 86.5mm wide, press-fit cups). Always match your bottom bracket to both the standard and your frame's exact shell width before buying.

Which cranks fit a BB386EVO frame?

With the right bottom bracket, a BB386EVO frame can run cranks on several spindle standards. In our catalogue we have BB386EVO bottom brackets for: 30mm (BB30 / PF30 / 386EVO); 24mm (Shimano Hollowtech II); 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 BB386EVO bottom brackets and frames are listed?

We currently track 33 BB386EVO bottom brackets and 15 frames built to the BB386EVO standard, checked against our compatibility engine.

My BB386EVO 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.
