maintenance
Inspect bearing condition annually (at a minimum) and anytime the crankset assembly is disassembled
or serviced. With the crankset removed, rotate the inner bearing race of both bearings; rotation should
be smooth. No play or movement inside the shell. If the bearing is damaged, replace both bearings with
new ones.
bearing removal
Remove the old bearings with the bearing removal tool
KT011/.
bearing installation
To install bearings, use a headset press and Cannondale tool

. Clean inside of shell apply a high-
quality bicycle bearing grease to the inside surface. Press bearing one at a time. Press each bearing until
seated. Following installation, apply a light coating of a high-quality bicycle bearing grease to both sides
of each bearing to help repel moisture.
Do not re-use removed bearings. Install both bearings as a new set.
NOTICE
bearings
- Frequent or routine renewal of undamaged bearings is not recommended. Repeated
removal and reinstallation can damage the inside BB shell surfaces resulting in poor bearing fit. Do
not face, mill or machine the bottom bracket shell for any reason. Doing so can result in serious
damage and possibly a ruined bike frame.
Do not cut, face, or use abrasives to clean the inside if the BB shell.
We strongly recommend that these procedures be performed by an Authorized Cannondale Dealer.
Damage caused by improper installation/removal is not covered under your warranty.
Carbon frames have a 46 mm I.D. bottom bracket bearing system press interface. The shell width is
73mm.
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. Make sure the bearings(cup or adpater
parts) are driven out squarely and evenly from inside the shell!!! Do not pry components from shell.
replacement
PressFit BB30 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 sure 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. Use a headset
press such as Park Tool HHP-2. See http://www.parktool.com/product/bearing-cup-press-HHP-2 Select
appropriate press and adapters to ensure that force is only applied to the cup and not the bearing inside.
Press until the both cup flanges are mated to the BB shell edge.
