HEADSHOK
Congratulations and thanks for your purchase
of the HeadShok Lefty suspension system. You
have invested in a suspension system that is
light weight and offers maximum adjustability
and absolute steering precision. This owner's
manual contains important and useful infor-
mation regarding the proper operation, care,
and maintenance of your HeadShok fork.
Please read it carefully and follow its instruc-
tions for miles of safe, high performance rid-
ing. If you have any questions about your fork
or the contents of this manual, don't hesitate
to contact us. See the back page for phone
numbers and E-mail contacts.
The Lefty fork is a new front wheel suspension
device, unlike any other fork on the market.
Using an integrated axle and a single leg, the
Lefty is as strong and stiff as any standard
two-legged long travel fork while being lighter
weight. The Lefty is available in three configu-
rations—The Electronic Lock Out (Lefty ELO)
which features push button lock out from the
handlebar, the Dial Lock Out with Rebound
adjustment (Lefty DLR) with on-the-fly lock
out and rebound damping adjustment, and the
Mechanical damper (Lefty M).
The axle spindles on the Lefty ELO and DLR
are titanium for the ultimate in light weight
and strength. The spindle on the Lefty M is
cast stainless steel for durability and corrosion
resistance.

FORK PRE-RIDE CHECKLIST
Before each ride, check the following items:
Stem bolts: Make sure that the stem bolts that
clamp the stem to the fork are tight. Each bolt
should be tightened to 77-94 In-Lbs (8.7-
10.5 Nm). You can check that the stem bolts
are tight enough by standing in front of your
bicycle, holding the front wheel between your
knees, and trying to twist the handlebars from
side to side. The bars should not move.
Wheel attachment: Is your rear wheel's quick-
release skewer properly fastened? Be sure to
read Section 6 of the Cannondale Owner's
Manual on proper operation of quick release
skewers. Is the Lefty hub correctly installed
and the hub bolt properly torqued to 133 In-
Lbs (15 Nm)? See the section titled "Front
Wheel Installation" later in this manual for
proper Lefty hub installation instructions.
Brakes: Are your brakes functioning properly?
With disc brakes, the brake pads must be
properly installed and free from grease or oil
contamination. Also, the brake pads must con-
tact the braking surface firmly without the
brake lever hitting the handlebar.
WARNING: The Lefty fork must be used with a
CODA or other compatible disc brake, as the disc
brake acts as a secondary wheel retention
device. Failure to have a properly installed disc
brake rotor on the Lefty hub and a properly
installed disc brake caliper on the Lefty fork
could allow the front wheel to come off of the
3
assembly and battery changes (available
from tool makers such as Park, Pedro's or
X-Axis)
U9VL-J or U9VL (also available from
retailers such as Ace Hardware, Home
Base, Radio Shack, Sears, and True Value
Hardware)
