COMPATABILITY
PressFit 30 compatible frames have a 46 mm I.D. bottom bracket bearing system press interface. PressFit
30 compatible frames may have a shell width of 68 mm or 73mm depending on the frame type. PressFit
30 bottom bracket bearing systems from various manufacturers enable the installation of BB30 cranksets.
ThePressFit 30 bearing system on your bike may differ from the one shown.
MAINTENANCE
In general, you should inspect the condition of the bearings annually (at a minimum) or anytime the
crankset assembly is disassembled , serviced, or if a problem is indicated.
To inspect, when the crankset is removed, rotate the inner bearing race of both bearings; rotation should be
smooth, and quiet. Execesssive play, roughness or corrossion indicates a damaged bearing.
REMOVAL
To avoid serious damage to the frame, it is important to remove bearing systems very carefully using
proper tools indicated by the manufacture’s service instructions. For the PressFit 30 system shown, push
out bearing units from opposite sides using a head cup remover such as Park Tool RT-1. See http://www.
parktool.com/product/head-cup-remover-RT-1 Make sure the bearings(cup or adpater parts) are driven out
squarely and evenly from inside the shell!!! Do not pry compoenents from shell.
REPLACEMENT
PressFit 30 bearings are not removable from the adapters or cup systems that are pressed into the frame
bottom bracket shell. Therefore, damaged bearings must be removed and replaced as new entire sets.
Before installing any new bearing units into the shell, thoroughly clean the inside surface of the bottom
bracket shell with a clean dry shop towel. Also, make use both bearing units and the BB shell surfaces are
clean and dry. Do not apply grease to either.
Follow the manufacture’s instruction for assembly and installtion of the bearing system. Bearing units
should both be pressed at the same time with slow even pressure. This will help ensure bearing unit enter
squarely and they do not become tilted. Use a headset press such as Park Tool HHP-2. See http://www.
parktool.com/product/bearing-cup-press-HHP-2 Select appropriate press adapters to ensure that force is
only applied to the cup (arrows in illustration) and not the bearing inside. Press until the both cup flanges
are mated to the BB shell edge.
