WARRANTY INFORMATION
CONGRATULATIONS ON CHOOSING A 2003 MANITOU SIX FORK. This Manitou
SIX fork is fully assembled and ready to be installed onto your bicycle. It comes
equipped with a 1 1/8-inch threadless steerer tube, RA casting and is available
with a V-brake-style hangerless arch. SIX forks are also available in a disc brake
only version. A handlebar-mounted reflector must be used for on-road use,
which is not included with your fork.
Any Answer Products fork found by the factory to be defective in materials
and/or workmanship within one year from the date of purchase (or two years in
EU countries) will be repaired or replaced at the option of the manufacturer, free
of charge, when received at the factory with proof of purchase, freight prepaid.
This warranty does not cover breakage, bending, or damage that may result
from crashes or falls. This warranty does not cover any fork that has been subject to misuse or whose serial number has been altered, defaced or removed.
This warranty does not cover paint damage. Any modifications made by the
user will render the warranty null and void. This warranty is expressly in lieu of
all other warranties, and any implied are limited in duration to the same duration as the expressed warranty herein. Answer Products shall not be liable for
any incidental or consequential damages. If for any reason warranty work is
necessary, return the fork to the place of purchase. At that time, instructions for
repair, return, or replacement shall be given. Customers in countries other than
USA should contact their dealer or local distributor.

BICYCLING IS A HAZARDOUS ACTIVITY
THAT REQUIRES THAT THE RIDER STAY
IN CONTROL OF HIS OR HER BICYCLE AT ALL TIMES. READING THIS MANUAL
ENTIRELY, AND PROPERLY MAINTAINING YOUR BICYCLE AND SUSPENSION
FORK, WILL REDUCE THE POSSIBILITY OF INJURY OR POSSIBLE DEATH. PRIOR
TO RIDING YOUR BICYCLE, YOU SHOULD INSPECT YOUR SUSPENSION FORK TO
ENSURE THAT NO DAMAGE HAS OCCURRED DURING THE COURSE OF RIDING.
DO NOT RIDE YOUR BICYCLE IF THE FORK SHOWS ANY SIGNS OF BENDING,
CRACKING, CREAKING, LEAKING, OR IF IT IS MISSING ANY OF THE ORIGINALLY
SUPPLIED COMPONENTS. ANY FALL FROM YOUR BICYCLE CAN RESULT IN
SERIOUS INJURY OR EVEN DEATH. FOLLOWING THESE INSTRUCTIONS CAN
HELP YOU REDUCE THE RISK OF BEING INJURED. IF YOU ARE A MODERATE OR
AGGRESSIVE OFF-ROAD RIDER, OR RIDE AT LEAST THREE TIMES A WEEK OVER
ROUGH TERRAIN, ANSWER RECOMMENDS RETURNING YOUR SUSPENSION
FORK EVERY 2 YEARS FOR A THOROUGH INSPECTION AND UPDATE. TAKE
YOUR FORK TO A MANITOU AUTHORIZED DEALER WHO CAN ARRANGE FOR
SHIPMENT TO ANSWER PRODUCTS, OR YOU MAY CALL ANSWER AT (661) 2574411 TO HAVE YOUR FORK SHIPPED DIRECTLY.
IMPORTANT: The SIX fork is an off-road fork, and as such, does not come
with proper reflectors for on road use. Have your dealer or mechanic install
proper reflectors to meet the Consumer Product Safety Commission’s
(C.P.S.C.) Requirements for Bicycles if the fork is going to be used on public
roads at any time. If you have questions regarding C.P.S.C. Standards, or
would like to purchase a reflector bracket kit (Part #85-3674), contact
your dealer.
CONSUMER SAFETY INFORMATION
1. Never remove or have the steerer tube or stanchions removed from the
crown. The steerer tube and stanchions (inner legs) are press fit at the factory. Press fit inner legs have higher performance versus bolt-in inner legs, but
can not be pressed out. Pressing them out will permanently damage the
crown beyond repair and render it unsafe for any continued use.
2. Never attempt to thread a threadless steerer tube. Cutting threads will weaken the steerer tube and cause an unsafe condition. The only safe thing to do
is to obtain the proper crown/steerer from your dealer, or contact Answer
Customer Service at (661) 257-4411.
3. Any other alteration or modification to your fork should be considered
unsafe. Contact Answer Customer Service prior to modifying your fork in any
way for safety information.
4. Do not use the SIX fork if any parts are broken, bent, cracked, or you suspect may be damaged. Contact your dealer or Answer Warranty (661) 2574411 if you have any questions concerning the integrity or condition of your
fork.
5. Answer Products recommends that you inspect your fork before every ride
for wear and damage. Inspect the crown, inner legs, outer legs dropout and
brake arch areas for cracks or damage.
INSTALLATION INSTRUCTIONS
Ensure that the proper steerer tube has been delivered on your Manitou SIX.
The steerer tube may need to be cut to length to fit your bicycle head tube. If
you are not familiar with this procedure, or do not have the proper tools to cut
the steerer tube, it is recommended that you seek a dealer with a qualified bicycle mechanic to perform installation.
THE STEERER TUBE AND STANCHIONS (INNER LEGS)
ARE A ONE TIME PRECISION PRESS FIT AT THE FACTORY AND CAN NOT BE REMOVED FROM THE CROWN. REPLACEMENT OF THE
ENTIRE CROWN/STEERER ASSEMBLY MUST BE DONE TO CHANGE STEERER
TUBE LENGTHS OR DIAMETERS. REMOVING AND REPLACING THE STEERER
TUBE OR STANCHIONS WILL RESULT IN AN UNSAFE CONDITION AND SHOULD
NEVER BE DONE.
BREAK-IN
Your new fork is designed to break-in during your first few rides (about 20
hours total riding time). Prior to break-in, you may notice your fork binds
slightly and feels notchy. Following the break-in period, your fork will feel much
smoother and will react to bumps much better than when you first put it on
your bike. After 20 hours, you may want to recheck your rebound and preload
adjustments (when applicable) to fine tune the fork completely. Between services on your Manitou fork, all you must do is lubricate your fork as needed with
Manitou Prep M (part number 85-3810 for the lube and 85-3812 for the injector
gun) via the Microlube grease ports located on the back of the fork legs.
FORK INSTALLATION
1. Remove the old fork from your bicycle.
2. Measure and cut the steerer tube to fit your bicycle head tube. You can use
your old fork as a guide for cutting the steerer tube length.
3. Remove the headset crown race from the old fork and press onto the
Manitou SIX steerer tube until the race is seated over the crown.
4. Clean and grease the headset bearings and races.
5. Install the lower bearings (if applicable) on the fork crown race.
6. Insert the steerer tube into the head tube of the frame.
7. Install the upper bearings, stem spacers, and stem.
8. Install the stem cap and bolt. Tighten the bolt to headset manufacturer’s
specifications.
9. Install the handlebars to desired height and the torque stem pinch screws
or stem clamping system to manufacturer’s specifications.
10. Install the brakes and adjust per the manufacturer’s instructions.
11. For all SIX forks, adjust the front wheel quick release to clear the 0.334"
(8.5 mm) thick secondary catch dropout. The quick release must be tightened after it is properly seated into the dropout counter bores to manufacturer’s specifications. Ensure that there is adequate thread engagement (4
or more threads with the release adjusted to lock).
NOTE: 2003 Manitou SIX forks are equipped with a secondary catch dropout to
retain the wheel in the fork in the event the quick release comes loose.
WHEN INSTALLING THE WHEEL OR A NEW TIRE, CHECK
TO MAKE SURE THE FORK ACHIEVES MINIMUM TIRE
CLEARANCE. MEASURE FROM THE HIGHEST POINT ON THE TIRE TO THE BOTTOM OF THE BRAKE ARCH. THIS MEASUREMENT SHOULD BE 10 MM. (FIGURE
1)
IMPORTANT: The Manitou SIX fork should not be used if any parts appear
to be or are damaged. Contact your local dealer or Answer Products for
replacement parts.
MAINTENANCE
IMPORTANT: Use of fork boots is required to keep your Manitou SIX fork
performing well and the warranty in effect. Use of this fork without boots will
shorten the life of the fork, decrease the time between maintenance intervals, reduce the performance and void the warranty.
IMPORTANT: When lubricating the fork with grease through the grease

Thank you again for choosing a 2003 Manitou SIX suspension fork.
ports, it is important to note that grease is being forced between the upper
and lower bushings. If the area is overfilled, the grease may force the upper
bushing and dust seal out. You should only insert grease to the level at
which stiction (stickiness when you compress the fork) is no longer felt.
IMPORTANT: Before every ride you should:
1. Ensure that quick release skewers are properly adjusted and tight.
2. Wipe the inner legs and clean and check entire fork for any obvious damage.
3. Check the headset for proper adjustment.
4. Ensure that the front brake cable is properly routed and check brake
adjustment.
SIX DEALER SERVICE ADDENDUM
This section is designed to help you tune and maintain your Manitou
suspension fork.
MEASURING SAG To measure sag, you’ll need a tape measure,
a pencil, a piece of paper and a helper.
1. Measure the distance from the front axle’s centerline to the bottom of
the upper crown when no one’s sitting on the bike and write this distance down. (Remember the exact locations of the two points because
you’ll need to use them later.)
2. Have the rider sit on the bike and measure the distance between the
same two points as in step one. It’s important to be in the normal riding position (weight centered) with the rider’s feet on the pedals.
3. Subtract the second measurement from the first. The resulting measurement is the static sag or ride height.

CHANGING SPRINGS AND/OR MCU’S Once you have checked
sag, you can either preload the spring via the cap on top of the left hand
leg, or even better, make spring changes to accommodate for your riding
style and weight.
1. Start by removing the preload adjuster by unscrewing the 2 mm hex
bolt on the adjuster knob (Figure 2). A 20 mm socket will be necessary with the SIX. Remember: The springs are housed only in the left
leg on 2003 Manitou suspension forks. (Figure 3)
2. With the adjuster assembly removed, the spring stack is now
accessible.
3. Select the appropriate coil spring for your weight and riding style
(refer to the above spring chart for recommended rates).
4. Apply a liberal amount of grease to the outside surface of the new coil
spring (Figure 4). We recommend any thick grease (not light greases
like Prep M). Install the new spring stack.
5. Reinstall the preload adjuster knob and adjuster assembly, taking
care not to cross-thread the adjuster assembly. It should be snug
tightened with a wrench. (Figure 5)
CONVERTIBLE TRAVEL
1. Changing the travel from 80 to 100 millimeters or vice-versa requires
the removal of the lower legs.
2. Unthread (clockwise to loosen) the 8 mm and 4 mm bolts on the bottom of the fork and pull the lowers free from the uppers. Unscrew the
cap on the bottom of the right leg (as seen from the rider’s position).
This will expose the clip that is used to adjust the travel. (Figure 6)
3. Remove the clip and insert it into the upper position (above the rod
flange) for 100 millimeters of travel or the lower position (below the
rod flange) for 80 millimeters of travel. (Figure 7)
4. Reassemble fork.
MAINTENANCE AND SERVICE – INTRODUCTION When servicing the fork, take the time to inspect all parts for excessive wear or
damage. There are basically three aspects of a fork that will require
attention: the stanchions (inner legs), the bushings in the outer legs
and the spring stack. Inspecting any of these parts requires disassembly of the fork. Pay close attention to the bushings, which can be damaged by contamination in severe conditions. Replace any worn or damaged parts that are discovered.
FORK DISASSEMBLY Disassembly of your SIX fork is necessary
to provide the proper service of your fork. To do this:
1. Remove the bolts from the bottom of the fork leg with 4 and 8 mm
wrenches and set aside. (Figure 8)
2. You can now pull apart the fork, removing the casting from
crown/steerer assembly. (Figure 9)
3. Wipe clean the inside of the fork casting, stanchion tubes, fork boots,
and crown. At the same time you do this, do a complete inspection on
the fork. (Figure 10)
MICROLUBE
All you need is a Microlube lubricant gun
(part #85-3812) and Manitou’s Prep M suspension fork lubricant (part
#85-3810). Brush any dirt from the grease ports and inset the grease
gun into the small fitting located at the back of the fork and squeeze a
few times. Continue injecting grease and push the fork up and down
until stiction is eliminated.
