Item # SHI0461

A go-to bracket for Shimano cranks.

Simple, reliable, and smooth, Shimano's XTR BB94 Bottom Bracket presses easily into your frame to give you long-lasting and nearly friction-free pedaling. The stainless steel bearings, composite body, and composite cups are designed to work with Shimano HollowTech II cranks, and the threadless nature of the bracket makes installation a breeze. A small plastic O-ring keeps dirt, water, and debris sealed out, too, so you can put away the miles without worrying about conditions.

It Works

  • Familiarity: I've put it through the wringer

This is the bottom bracket you need to pair your Shimano crank to your press fit bb. Super easy to install and the bearings held up for over a year before they started feeling gritty after riding in variable conditions.

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.
