INSTALLATION
1. Inspect inside the wheel hub for contamination and
the condition of the hub seal. Take corrective action if
necessary.
Wipe the spindle clean with a dry shop towel and apply a
high-quality bike grease to the spindle bearing lands and
end threads.
2. Slide the wheel straight onto the spindle so, the larger
hub bearing starts to position on it spindle seat. At this
point, the axle bolt threads can correctly engage the
threaded spindle if the wheel is held on straight.
NOTE: Install the front wheel by positioning the bike
horizontally with the spindle facing up. Then place the hub
straight down onto the spindle, and tighten the axle bolt.
3. When the axle bolt threads engage the spindle, turn the
bolt clockwise with nger force slowly to allow the hub
bearings to slide onto the spindle bearing seats.
Once the hub has been drawn onto the hub completely,
use torque wrench to tighten to nal 15.0 N•m (133.0
In•Lbs).
4. Reinstall the brake caliper. Tighten bolts to 78.0 In•Lbf
(9.0 N•m).
5. Spin the wheel to make sure it moves freely. Be sure to
test the brakes for proper operation before riding.
WARNING
DO NOT CONTAMINATE BRAKE CALIPER, PADS, OR
ROTOR WITH GREASE.
WARNING
DO NOT RIDE WITHOUT A PROPERLY MOUNTED,
ADJUSTED, AND FUNCTIONING FRONT BRAKE
SYSTEM.
The Lefty (disc/caliper) acts as an integral secondary
wheel retention system. If the system is missing or
improperly installed, or if the wheel hub axle bolt should
loosen, the front wheel could slide o the spindle end.
When mounting IS compatible brake systems:
Follow brake manufacturer’s instructions when mounting
the brake caliper to the spindle brake bosses. Do not
modify the fork in any way.
PLEASE ASK YOUR CANNONDALE DEALER FOR HELP
WHEN INSTALLING COMPATIBLE FRONT BRAKE
SYSTEMS.
NOTICE
■ LOCATE BRAKE ROTOR BETWEEN THE PADS.
Replace shims that are in use, be sure the shims are
positioned between the caliper (adapter if any) and
inner face of the fork mounts, not under the head of
the caliper bolts.
■ USE ONLY THE LEFTY 16mm CALIPER BOLTS TO
MOUNT THE BRAKE. Longer bolts can result in
contact with the brake rotor causing severe damage.
Check clearance between the bolt tips and rotor after
remounting the caliper. Order replacement bolts -
Cannondale p/n LEFTYBOLTS/.
■ MAKE SURE THE BRAKE DISC CAN NOT MAKE
CONTACT WITH THE FORK BOOT. A rotating brake
disc can wear through the boot allowing contaminants
into the fork.
