NOTICE
■ When the caliper is disconnected from the post mounts, be sure to handle it carefully
to avoid damaging it.
■ When the wheel is off, to keep dirt out, cover the hub opening.
■ Protect spindle from damage when wheel is removed.
WHEEL 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.
Figure 10.
TIP: 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 finger
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 final 15.0 Nm (133.0 In Lbs).
4.
Reinstall the brake caliper. Make sure the brake disc locates between the caliper pads
and you return any shims/washers between the post mounts and the brake caliper.
Tighten the caliper bolts with a torque wrench. Consult the brake manufacturer's
instructions. In any case, the disc brake caliper mounting bolt tightening torque level
must never exceed 10 Nm, 88.5 In Lbs.
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 brake system (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 off the spindle end.
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.
