ASTM CONDITION 4
WARNING
RIDING WITH DAMAGE IS DANGEROUS.
STOP RIDING IMMEDITE IF DAMAGE IS
PR ESENT.
The following conditions indicate that serious fork damage is
present:
• Any unusual “klunking” or knocking noises.
• Change in travel.
• Changes in normal functions.
• Loss of adjustments features, oil leaks, or air leaks.
• Crash or impact damage (deep scratches, gouges, dents,
or bending)
• Any small cracks under the bolt head of upper and lower
clamp bolts. This inspection requires the removal of the
bolts.
• Horizontal cracks above and below the intersection of the
upper and lower clamps with the outer tube portion of the
Lefty structure.
• Vertical cracks in the outer tube (where the races and
needle bearings run). These may show as long, straight
lines perhaps several lines parallel to each other.
Please read Inspect For Safety in PART II, Section D. of your

Disassembly or Modification
WARNING
DO NOT DISASSEMBLE OR MODIFY YOUR
LEFT Y IN ANY WAY.
Improper service or modification can lead to serious fork
damage or serious personal injury.
• Do not disaassemble the fork.
• Do not attempt modification in any way.
• Do not drill, file, cut or remove material from any
part.
• Do not attempt to repair damage.
• Do not weld, clamp, or bond anything to the fork.
• Do not attempt to remove the damping cartridge or
other internal fork parts.
The MAINTENANCE section of this supplement
includes information about regular owner maintenance
practices that can keep your fork in good operating
condition.
All other service and maintenance procedures must be
completed through an Authorized Headshok Service
Center. Contact your Authorized Cannondale Dealer for
more information.
YOU CAN BE SEVERELY INJURED,
PARALYZED OR KILLED IN AN ACCIDENT
IF YOU IGNORE THIS WARNING.
Tire-to-Crown Clearance
WARNING
Modification or installation of damping cartridge/spacers
other than specified; or installing over-sized tires can result in
incorrect tire-to-crown clearance
2
10mm
If tire clearance is less than minimum specified, the rotating tire
could come into contact with the frame causing the wheel to
stop suddenly. This can throw a rider off the bicycle or result in
a loss of control and crash.
CHECK FOR MINIMUM TIRE FORK/
FRAME CLEARANCE (10 mm) WITH ALL
AIR RELEASED FROM LEFTY AND FULLY
COMPRESSED.
Measure between the top of the properly inflated tire (1) and
the bottom of the fork steerer (2).
YOU CAN BE SEVERELY INJURED, PARALYZED
OR KILLED IN AN ACCIDENT IF YOU IGNORE

■ Either a Supermax 2.0 or LEFTY HYBRID wheel hub may be used with the Supermax 2.0. The wheel hub must be matched with its correct
brake adapter. See item 21 on previous page.
■ The hub cap is a left-hand thread. It retains the axle bolt assembly within the and should only be removed when replacing the bearings
or axle bolts parts, not when removing the wheel.
■ The axle bolt is a right hand (normal) thread. Insert a 5 mm allen key. Turn it clockwise to install a wheel. Turn it counter-clockwise to
remove a wheel.

Setting Sag
Sag is the distance the Supermax 2.0 compresses when the bike is statically loaded with your body weight in your riding
position. Set it according to the Supermax 2.0 travel. Sag is set by changing the air pressure through the Schrader valve at the
bottom of the Supermax 2.0

Minimum: 50 psi, 3.4 bar
Maximum: 225 psi, 15.5 bar

To set sag:
1. Remove the Schrader valve cap (1) at the bottom of the
Supermax 2.0 Attach a bicycle suspension pump to the
Schrader valve (2). See Figure 1.
131581.PDF
2. Set the recommended intial starting air pressure
according to your weight.
3. Slide the sag O-ring (3) against the wiper seal (4). See
Figure 2.
3. Sit on bike in riding position and dismount.
Note: Your riding position affects weight distribution and
therefore sag. For example, in the “Attack” position
(Figure 3). the rider’s weight is distributed equally
front and rear.
4. Measure the sag distance. See Figure 4.

Wheel Removal
1. If needed, loosen the brake line clamp on the front of the
moto guard so the line can move freely. This will make
handling the brake caliper and attached adapter easier.
2. See Figure 1. Use a 5 mm Allen key to loosen and
back out both brake adapter mounting bolts enough so
that the adapter and attached caliper can slide up and be
removed from the spindle together. It is not necessary to
completely remove the adapter bolts.
131581.PDF
Carefully move the brake caliper out of the way and
protect it from damage.
2. See Figure 3. Insert a 5 mm Allen key into the axle
hub bolt and turn it counter-clockwise.
Continue turning the extraction bolt until the wheel is
disenaged and can be removed easily from the spindle
end.
See Figure 4.
NOTICE
■ Make sure the axle bolt is completely disengaged
before attempting to remove the wheel. Never try
to pull the wheel off forcefully.
■ When the wheel is off, to keep dirt out, cover the
hub opening.
■ Protect spindle from damage when wheel is
removed.

Wheel Installation
1. Wipe the spindle clean with a dry shop towel. Apply a highquality bike grease to I.D. of the bearings inside the hub.
WARNING
DO NOT CONTAMINATE BRAKE CALIPER,
PADS, OR ROTOR WITH GREASE.
2. Slide the wheel straight onto the spindle. Turn the
axle bolt clockwise to engage the spindle threads. Make sure the
wheel and spindle are supported while tightening the hub bolt.
3. Once the hub has been drawn onto the hub completely, use
torque wrench to tighten to fi nal 15.0 Nm (133.0 InLbs).
Figure 1.
4. Reinstall the brake adapter onto the spindle bosses making sure
that the brake disc locates properly between the pads.
NOTICE
■ LOCATE BRAKE ROTOR BETWEEN THE PADS.
Apply Loctite 242 (blue to the threads and tighten the adapter
mounting bolts to 9 Nm, (78 IN Lbs). See Figure 2.
See
5. Spin the wheel to make sure it moves freely. Be sure to test the
brakes for proper operation before riding.
WARNING
DO NOT RIDE WITHOUT A PROPERLY MOUNTED, ADJUSTED,
AND FUNCTIONING FRONT BRAKE SYSTEM.
The (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.

WARNING
FREQUENT MAINTENANCE AND INSPECTION IS IMPORTANT TO YOUR SAFETY. YOU
CAN BE SEVERELY INJURED, PARALYZED OR KILLED RIDING ON A BROKEN OR POORLY
MAINTAINED FORK. Ask your Cannondale Dealer to help you develop a complete maintenance program, one that
suits where and how you ride.
EN
Page 13
Cleaning
Clean using only a mild soap and water solution. Clean water and common liquid dish washing soap will work best. Be sure to
cover the adjusters with a clean plastic bag secured with a rubber band or masking tape. Spray off heavy dirt before wiping.
Spray indirectly.
NOTICE
• DO NOT USE A PRESSURE WASHER. Use a low pressure garden hose. Power washing will force contaminants into the
fork promoting corrosion, immediately damaging, or result in accelerated wear.
• DON’T DRY WITH COMPRESSED AIR FOR THE SAME REASON.
Tightening Torques
Correct tightening torque for the fasteners (bolts, screws, nuts) on your bicycle is very important to your safety.the durability
and performance of your bicycle. We urge you to have your Dealer correctly torque all fasteners using a torque wrench. If you
decide to tighten fasteners yourself always use a good torque wrench!
The bumper cushions the frame from contact with the
Supermax 2.0. Replace it with a new one if it ever becomes
damaged, torn, or missing.
REPLACEMENT: Clean surfaces well. Remove the
backing from the new bumper, position and affi x by pressing
fi rmly against the frame.
IMPORTANT: Be sure to position the bumper so that
when the handlebar is rotated to the left, the bumper
prevents fork contact with the the frame. Frame damage can
result from using the wrong bumper or positioning a bumper
incorrectly. Ask your Cannondale Dealer for help.
