located at the bottom of the fork dropout act as a secondary wheel retention device and can reduce the risk of the
wheel disengaging from the fork if the quick release is not correctly adjusted and closed. It is possible for the tabs
to become worn out or damaged through repeated wheel installation and removal, car rack use, etc. Do not file,

All Cannondale carbon road forks with a carbon steerer tube must use the SI Compression Assembly - KP017/.
No star nuts, no other compression devices may be used, no exceptions. The SI compression assembly must be
assembled and installed inside the steerer tube according to the instructions. See page 95.
oldeR foRks & sTAR nUTs - Cannondale carbon forks (2001-2008) utilized the various star nut and top caps
systems. Systems in these forks should not be changed. Do not use the Si Compression Assembly in a fork
with a star nut.
Always tighten fasteners of the headset/stem system and brake with a torque wrench. Observe the
manufacturer's torque limits and loctite (thread locking compound) recommendations for each component of the
fork, stem, brake and handlebar system. Ask your cannondale dealer to help you. Over-tightening may cause
damage and lead to fork or component failure.
