bracket cranksets using the appropriate Cannondale frame adapter. Other adapters, ones not specifically
approved for use by Cannondale may void your warranty.

CaUtion
All Adapters must be installed by a professional bike mechanic. No adapter should be used as a frame
repair part. Adapters should only be used in undamaged frames in good condition. Improper installation
or removal can result in damage and void applicable frame warranty.
The adapter is removable, however, repeated removal and reinstallation could result in damage to the
SI BB shell and is not recommended. Damage caused by improper removal is not covered under your
warranty.
