Thoroughly clean the bottom bracket shell and make sure that the circlips are still correctly seated in their respective grooves, which are located just inboard about 1cm from the outer edges of the bottom bracket shell.

This step describes the budget option. The BB30 inner shell and crank spindle are usually aluminium, while the bearing races are steel, so copious amounts of grease can and should be used.

If possible, support the bottom bracket on a wooden block while knocking in the bearings. The Park BBT presses make life easier, but an old bearing or pipe drift will do it in a pinch, as long as it measures Never press or drift in a new cartridge bearing by the inner race only.

Position the headset press as pictured with the press plates up against the bearings and slowly tighten the press, ensuring it stays constantly aligned during the process. Press the bearings in until completely seated into the frame and bottomed out against the internal circlip stops. With Shimano Press-Fit the process is identical, but more force will be needed. Tighten until you see grease oozing from between the edge of the cups and bottom bracket shell, ensuring there are no gaps left.

Generously grease the spindle and insert the right side. Tap in with a mallet but protect the finish with a bit of tape. Grease the splined area of the spindle and reinstall the left crank arm, remembering the spacers, and tighten to spec. While you can just use a sturdy block of wood, a proper bearing press is a wise investment for any home workshop BikeRadar. Inspect the bearings for any signs of unusual wear and try to diagnose the cause BikeRadar. Make sure whatever piece of lumber you use has a solid, perfectly flat face BikeRadar.

Protect the finish of the cranks with a piece of tape BikeRadar. Torque up any pinch bolts to spec BikeRadar. The unitized nature of BBInfinite OPD cancels these forces out entirely, which means creaking has no place to start in the first place. It really is that simple. Every BBInfinite module ships with the special press tools, hardware, instructions, and the retaining compound you need to get the job done correctly with ease and confidence.
