PRAXIS SHIMANO BB30-PF30 Bottom Bracket

SAFETY INFORMATION – READ BEFORE THE RIDE

Since specific tools and experience are necessary for proper installation, it is recommended that the product be installed by a qualified bicycle technician.
Read the service instructions of your crank carefully prior to installing the parts. Loose, worn, or damaged parts may cause riding problems and serious injury may occur as a result. If installation and adjustments are not carried out correctly, the chain may come off and this may cause you to fall off the bicycle which could result in serious injury. Read these instructions carefully, and keep them for later use.

• Ensure that your BB30/PF30 frame shell is clean. If a BB30 frame, remove the c-clips/bearings so frame shell is empty.
• Before riding the bicycle, check that there is no play or looseness in the bottom bracket connection. Also, be sure to retighten the crankarms and pedals at periodic intervals.
• If you feel any looseness or ‘play’ in the bearings, the bottom bracket should be inspected/replaced.
• Be sure to read the instructions for your front chainrings/crank in conjunction with these service instructions.
• Do not wash the bottom bracket with high-pressure jets of water.
• For maximum performance, it is required to remove and periodically inspect/clean your Praxis Works bottom bracket.
• Parts are not guaranteed against natural wear or deterioration resulting from normal use.
• For any questions regarding methods of installation, adjustment, maintenance or operation, please contact a professional bicycle dealer or call Praxis Works.
• Praxis Works assumes no responsibility for damages or injury related to improperly installed components.

BB CUP PREPARATION

NON-DRIVE/LEFT CUP

1. Make sure the Width Tolerance O-ring is on the Left/Non-Drive Cup. This is required to accommodate frame BB width variances
2. FOR BB30 – Remove PF Sleeve (not used with BB30!). Apply a thin coating of anti-seize to both ends of the BB cup contact surfaces and the threads
3. FOR PF30 – Slide PF Sleeve on. Grease both ends of the PF Sleeve contact surfaces. Then put anti-seize on the inner threads

DRIVE/RIGHT CUP

1. Slide the Black Plastic Sleeve and then the Orange Rubber Collet onto the cup. This is critical to the function of your BB
2. Apply a thin coating of anti-seize to the Right/Drive cup threads
3. Apply a thin coating of grease to the outside of the Orange Rubber Collet and Black Plastic Sleeve

BOTTOM BRACKET INSTALLATION

1. With a press tool, GENTLY press the Left/Non-Drive cup into the frame’s Left/Non-Drive side until Width Tolerance O-ring just BARELY touches the side of the frame

2. Start threading the Right/Drive Cup in CLOCKWISE with your 16-Notch BB tool.
   As it threads in, you will feel friction build as the Orange Rubber Collet expands inside the frame. THIS IS NORMAL Now you must get your second BB tool…

3. TURN Right/Drive Cup UNTIL IT STOPS.
   With the 2nd BB tool, hold the Left/Non-Drive Cup in place while you tighten the Drive cup fully. The 2nd tool gives you leverage so you feel when the Drive cup bottoms out on the Non-Drive cup.

4. Lightly grease the underside of Dust/Seal Covers and place them over the bearings.
   Now you can install the crank

The Drive Cup has a machined stop and by design it MUST be tightened until it bottoms out on the Non-Drive cup. This precisely sets/stops the Collet expansion.

BOTTOM BRACKET REMOVAL

1. Unscrew the Right/Drive Cup COUNTER-CLOCKWISE and remove. Use one tool to hold the Left side for leverage, and the other to unscrew the Drive cup.
2. Once the Drive Cup is removed, slide a headset cup removal tool through from the drive side and it will catch the outside edge of the Non-Drive cup
3. Carefully bracing the tool and frame, very gently hammer/tap the removal tool to push the Non-Drive Cup out of the frame

BB DUST/SEAL COVER SETUP

REFERENCE – FRAME SPEC / VISUAL

YOU MUST VISUALLY INSPECT YOUR BB30/PF30 FRAME FOR OBSTRUCTIONS

• BB30 frames must have removable Clips for Conversion BB to be able to press in.
• Frame shell cannot have any inner shell obstructions that prevent B8 from installing.
• .DO NOT Modify! If you are unsure of your specific frame shell, please contact your frame .manufacturer.

EXAMPLE OF POTENTIAL OBSTRUCTIONS… These will prevent the Praxis unit from being installed.
