Bottom Bracket Installation

BB Frame and Cup Prep

Step 1: Apply grease or anti-seize to the frame & BB cup threads.

Step 2: Locate, read, and follow the directional arrows on the cups.

Step 3: Thread the Right/Drive cup into the frame's Right/Drive side.

Step 4: Thread the Left/Non-Drive cup with the attached moisture seal into the frame's Left/Non-Drive side.

Step 5: Finish by tightening both cups to 40Nm of torque using a Praxis M30 Tool.

Step 6: Refer to the BB Dust Cover Guide to find the correct Dust Covers for your crank. Lightly grease the underside of the Dust Covers and place them over the bearings with Praxis logos facing outward. The crank can now be installed.

For crank installation, please see instructions at www.praxiscycles.com/manuals.

BB Dust Cover Setup

Only 1 cover per side is used.

The Left/Non-Drive side requires a 28mm I.D. (Stepped Cover). The Right/Drive side requires a 30mm I.D. component, and a Wave Washer is also used for the Right/Drive side.
