Regular Professional Service
High performance precision suspension systems,
like the Lefty, require regular professional inspection,
lubrication, and maintenance.
Have your Lefty fork serviceh by an Authorized Can-
nondale dealer. A suspension professional will
check the following items and service the fork as
necessary.
FRAME AND FORK - Once a month, or every few
rides, clean and inspect the entire bicycle frame and
fork for any dents, cracks, or other damage. If any
damage to the frame or fork, is present, do not ride
t he bicycle . H ave t he dam ag e inspe cted an d
assessed by an Authorized Cannondale Dealer.
HEADSET BEARING SEAL - All Lefty forks which
come with the new lightweight Headshok stem
(which can be identified by its two clamp bolts) use a
secondary black rubber seal on top of the top
headset bearing. For the Lefty fork, this seal goes
below the top clamp, against the headset bearing.
This seal will keep water and dirt out of the headset
bearing. Have your Authorized Cannondale dealer
replace the seal if it is damaged.
SUSPENSION FORK BOOT - Frequently inspect
the rubber boot at the base of the leg of the Lefty
fork for tears, cuts, or broken zip ties that could allow
contamination. The fork boot protects the needle
bearings and races from water, dirt, and other con-
taminants. Make sure that the disc brake tubing has
not rubbed a hole into the boot. If the tubing is
rubbing on the boot, you should reroute it to elim-
inate the contact. Your Cannondale retailer can
assist you with this procedure.
If the boot is damaged in any way, it must be
replaced immediately. On the Lefty fork, it is nec-
essary to remove the front brake, loosen the leg
clamps using a 5mm Allen wrench, remove the
upper collar from the top of the Lefty leg (using a
40mm headset wrench or Green Park pin spanner),
drop the fork leg out of the clamps, and replace the
boot. To reinstall the leg, see the “Head Tube Angle
Adjustment” section of the manual. Your local Can-
nondale dealer can assist you with these proce-
dures. Damage to the Headshok due to contami-
nation by water or dirt will not be covered under war-
ranty.
The upper collar with 40mm wrench flats on the top
of the Lefty is not for any kind of adjustment. It is to
allow for the removal and service of the internal
components and removal of the leg from the clamps.
It should not be necessary to loosen or remove this
upper collar. If the collar is loosened or removed, it
should be lightly greased on the threads and rein-
stalled and torqued to 250 lbf•in(28 N•m).
Initial Service
When your bike is brought in for its 30-day tune-up,
the following procedures should be performed:
Boot inspection
Inspect the entire boot carefully for any cracking,
tears, rips or other damage that might allow dirt,
water, or other contaminants inside. A damaged
boot will allow corrosion and destroy the delicate
fork bearings and races. Always replace the boot
with a new one and make sure it is secured properly.
Needle bearing and stanchion tube inspection
and lubrication
Several times a year, or if the suspension boot has
been damaged, or if the fork has taken a large or
unexpected impact, you should inspect the inner
stanchion tube, bearing races beneath the boot.
You will need to replace the upper and lower boot zip
ties following the inspection procedure. These inex-
pensive ties should be available from your local
Cannondale Retailer.
1. Carefully cut and remove the upper and lower
zip ties securing the boot to the fork.
2. Slide the boot downward exposing the inner
bearing races.
3. Inspect the condition of the inner stanchion
tube and the exposed inner races. The
stanchion tube and races should be clean,
well lubricated and silver in color. If the races
or inner tube are corroded, pitted or damaged,
DO NOT CONTINUE TO RIDE THE FORK.
Contact an Authorized Cannondale Dealer for
service.
If there are no signs of damage or corrosion
are present, thoroughly lubricate the inner
tube and races with Royal Purple grease,
Finish Line White Teflon grease, or Slick 50
One Grease.
