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 If you have any questions regarding your 2003 Manitou SIX suspension fork, contact the Answer Products Customer Service Department at (661) 257-4411. You can also log on to www.answerproducts.com and download this manual or see detailed instructions on how to service your suspension fork. 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. SAG MEASUREMENT Fork Travel 80 mm 100 mm Sag 12-16 mm 18-24 mm TRAVEL MEASUREMENT To determine which travel your SIX fork is in, simply measure the distance from the top of the seal area on the lowers (or the bottom of the fork boot) to the bottom of the crown. Fork Travel 80 mm 100 mm Seal to Crown Measurement Around 4.3 inches or 109 mm Around 5.2 inches or 130 mm RECOMMENDED SPRINGS SIX Standard Set-up Rider Weight 100-150 lbs. 150-170 lbs. 170 plus lbs. Recommended Spring Kit Soft ride kit (Part #85-4826) Medium ride kit (Part #85-4827) Firm ride kit (Part #85-4828) 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.
