PressFit-30 (PF30) Bottom Brackets

Looking for a PressFit 30 bottom bracket? Kogel offers ceramic PF30 bottom brackets to fit just about any crankset including 30mm, 24mm, DUB and GXP crank spindles, so you’re sure to find a bottom bracket that mates your press fit bottom bracket shell with your crankset. 

About the PressFit 30 BB Standard

PressFit 30 (PF30) bottom brackets have a frame shell width of 68mm for road bikes and 73mm for mountain bikes. Inner diameter is 46mm.

The PressFit 30 has been widely used by many manufacturers over the years. From Cannondale and Specialized all the way to the small scale frame builders.

At the time of introduction it was deemed a way to increase stiffness, better fit 30mm crank spindles and reduce weight on carbon frames due to the elimination of threads, which require aluminum inserts to be bonded into the frame.

PF30 vs BB30 Standards

The main difference between the two standards being the intermediary cups that sit between the frame and the bottom bracket bearings.

BB30 bearings press directly into the frame, PressFit 30 bearings sit in a cup, which is pressed into the frame.

WHY Upgrade/Replace Your Bottom Bracket

Even new bikes with new high-end drivetrains can, and usually do, ship with bottom brackets using steel bearings.

Even if perfectly maintained, those steel bearings just won't roll as smoothly or efficiently as our ceramic steel bearings.

Kogel Ceramic Bearings are:

  • More symmetrical (i.e. round) and built to stricter tolerances than steel bearings
  • More efficient for power transfer than standard bearings
  • And, won't deform, flat-spot, crack or get pitted

Beyond the basics of keeping your bottom bracket clean and maintained, perhaps the most important step is ensure your bike's best performance is using a bottom bracket manufactured with high-quality ceramic bearings.

I feel like it motivates you to pedal even harder on the racetracks when you know that your BB runs so smooth and free
