Simple and Effective

  • Familiarity: I've put it through the wringer

The PF BB92 bottom bracket is intended for mountain bikes (compared to the PF BB86 made for road bikes). It's super easy to install since it's a press fit. The bearings quality is good, longevity dependent on riding conditions. Wet or sandy conditions will result in shorter bearing life.

Some things to consider: If you're installing in a carbon frame you might want to use carbon specific grease. It will reduce noise found later on down the trail.

Be particularly careful with the inner races during the install, they crack easily if misaligned in your press or if you decide to take action with a hammer.

Pay attention to the instructions regarding how to orient any spacers, your bike design and front derailleur type impact the BB spacing.
