axle spindle if the hub axle bolt is loose. A rider
would be at risk of injury or death if the front
wheel were to come off of the axle spindle while
the bicycle was being ridden.
WARNING: An approved disc brake system is
very important to the safety of the Lefty fork and
Cannondale strongly recommends that an author-
ized Cannondale dealer perform any work to the
brakes. When installing disc brakes to a Lefty
fork, please consult the disc brake fitting instruc-
tions that are included with the brakes. Those
instructions are provided for persons who have a
good knowledge of bicycle specific mechanical
procedures and who are equipped with the prop-
er tools and equipment. Incorrect installation or
service may reduce braking performance, and
could lead to injury or death. If you have any
doubts about your ability to perform any neces-
sary procedures, contact your local authorized
Cannondale dealer.
Note that the thinner disc brake mount on the
Lefty fork may require shorter caliper mount-
ing bolts when used with a CODA Disc Brake.
See your local Cannondale dealer for assis-
tance if you need these shorter bolts.
Note also that there is a seal that is held
against the disc side of the Lefty hub by the
disc brake rotor. Whenever you bolt the brake
rotor onto the hub, be sure that the seal rests
against the large cartridge bearing and that the
rotor holds the seal in place. The seal keeps
out water and dirt contamination, and a miss-
ing seal will result in premature bearing wear.
If you have any reason to suspect that your
bicycle is not functioning properly, do not ride it.
Instead, have it inspected by your authorized
cannondale retailer.

FORK SETUP
Before the Lefty ELO can be used or the bike
ridden, the ELO battery must be installed and
the system reassembled. The ELO uses an
Ultralife lithium 9 volt battery to power the
motor which activates the lock out function
within the Lefty. For shipping purposes, the
battery and Electronic Control Unit (ECU) are
packaged separately. The battery and ECU
must be installed within the Lefty and the
push button switch installed on the handlebar
before the system will be functional. The ECU
holds the battery, and houses two LEDs to
indicate fork lock out (red) and low battery
(yellow). Be careful not to damage the
attached switch wire when handling this
piece.
ELO BATTERY INSTALLATION
1. Using a 40mm headset wrench, unscrew
and remove the upper collar from the top of
the Lefty leg. See Fig. 1 for an illustration of
the ELO components.
2. Using a 5mm hex wrench, loosen the fork
upper clamp bolt. Compress the fork so that
the top of the cartridge comes up through the
top of the Lefty leg. This may be easiest to
achieve by placing the bike upright on the
floor and pushing down on the handlebars.
3. Press the new battery into the battery con-
nection on the top of the cartridge so that the
terminals mate. See Fig. 1.
Note: Do not remove the two hex head screws
adjacent to the battery termi-nals on the car-
tridge outer cap for any reason. These are
