Torque requirement: 16-20 ft.. lbs. 15 QUICK RELEASE FRONT WHEEL Some bicycles have wheel axles that incorporate a Quick Release (QR) mechanism. This allows easy wheel removal without the need for tools. The mechanism uses a long bolt (called a skewer) with an Adjusting Nut on one end, and a lever operating a cam-action tensioner on the other. With the quick release lever in the open position, insert the front wheel into the open ends of the fork. Turn the adjusting nut so that the locking lever is moved to the closed position with a firm action. At the halfway closed position of the quick release lever, you should start to feel some resistance to this motion. Do not tighten the quick release by using the quick release lever like a wing nut. If the quick release lever is moved to the closed position with little or no resistance, clamping strength is insufficient. Move the quick release lever to the open position, tighten the quick release adjusting nut, and return the quick release lever to the closed position. Quick Release Adjusting Axle (skewer) Nut Hub Axle Quick Release Cam Lever Hub Closed Position CORRECT QUICK RELEASE AXLE SETTING: 1. To set, turn the lever to the open position so that the curved part faces away from the bicycle. 2. While holding the lever in one hand, tighten the Adujusting Nut until it stops. 3.

THE SEATPOST “MINIMUM INSERTION” / “MAXIMUM HEIGHT” MARK SHOULD NOT BE VISIBLE WHEN THE SEAT POST IS INSERTED INTO THE SEAT MAST OF THE BIKE. DO NOT RAISE THE SEAT POST BEYOND THIS MARK. THE SEAT POST OR FRAME MAY BREAK CAUSING YOU TO LOSE CONTROL AND FALL. ALWAYS CHECK TO MAKE SURE SEAT POST ADJUSTING MECHANISM IS TIGHTENED SECURELY BEFORE RIDING. RIDING WITH AN IMPROPERLY TIGHTENED SEAT POST CAN ALLOW THE SEAT TO TURN OR MOVE AND CAUSE THE RIDER TO LOSE CONTROL AND FALL. 25 HAND BRAKES Determine which type of brake your bike is equipped with and refer to the appropriate assembly instructions. If your bike comes equipped with a foot brake ONLY, no brake adjustment is required. For more information on brake adjustment and maintenance, refer to the maintenance section of this manual. NOTE: A greater force is required to activate the rear brake due to longer cable length. It is important to become familiar with the use of hand brakes. When properly adjusted, hand brakes are an efficient braking system. Keep the rim and brake shoes clean and free from wax, lubricants and dirt at all times. Keep brakes properly adjusted and in good working condition at all times. Open the brake lever and place the cable head end of the short brake cable into the lever, then close the lever. Secure the ferrule against the lever using the cable adjusting barrel. Assembling Brake Cable to Brake Lever Cable Adjusting Barrel Handlebar Cable Brake Lever Ferrule Grip Cable Head SIDE PULL CALIPER BRAKE Minor brake adjustments can be made using the cable adjusting barrel. To adjust, squeeze the brake pads against the rim, loosen the lock nut and turn the cable adjusting barrel located on the side pull caliper brake. Brake pad clearance should be a maximum 2mm from the rim. When correct, re-tighten the lock nut. If the pads cannot be set close enough to the rim in this manner, you may have to adjust the cable length. Screw the cable adjusting barrel 3/4 of the way in, squeeze the pads against the rim, undo the cable anchor bolt and pull the cable through with pliers. Re-tighten the cable anchor bolt and apply full force to the brake lever to test, then fine tune using the cable adjusting barrel. If one pad is closer to the rim than the other, loosen the fixing nut at the back of the brake, apply the brake to hold it centered, and retighten the fixing bolt. Turn cable adjusting barrel to lock cable into place. Side Pull Brakes Lock Nut Cable Adjusting Barrel Brake Arm WARNING! ENSURE THE BRAKE FIxING NUT IS SECURED TIGHTLY. FAILURE TO DO THIS MAY CAUSE THE BRAKE ASSEMBLY TO DISLODGE FROM THE FORK. Most side-pull calipers also have a centering adjustment bolt, which enables you to properly center the caliper over the rim. This should be set so that there is an equal distance between the brake pad and the rim on both sides of the wheel. You should also check to be sure that the brake pads themselves are properly adjusted. The pad should contact the rim so that it is centered from top to bottom on the rim surface. It is important that there is no less than 1mm of distance between the top of the brake and the top of the rim in order to ensure that the brake pad does not contact the tire in any way. 26 Centering Adjustment Bolt Quick Release Lever Brake Shoe Fixing Nut In Back V-BRAKE ASSEMBLY & ADjUSTMENT If not already assembled, take the brake noodle from the parts box and slide the cable through the larger opening. The cable housing will then seat into the end of the noodle. Slide the cable through the cable lead on Slip the brake cable boot over the cable and position it between both brake arms. Next, loosen the 5mm anchor bolt at the end of the right brake arm and slide the cable under the retaining washer. Pull the slack out of the cable making sure a distance of 39mm or more remains between the end of the lead and the start of the anchor bolt. Once the cable is secured to the brake arms, engage the brake lever several times, checking the position of the brake shoes at the rim. The brake shoes should be 1mm away from the rim when in a relaxed position. When the brake lever is engaged, the touching the rim slightly before the rear. This is called “toeing-in” your brake shoe. If this position is not achieved, adjustments to the brake shoe are required. Loosen the brake shoe hardware and reposition the brake shoe. It may take several shoe and cable adjustments before the required position is accomplished. 27 Outer Cable Lead Brake Noodle Brake Cable Boot 39mm or more Anchor Bolt Brake Arm/Body Pivot Bolt Brake Shoe Tension Screw 2.

Your bicycle has been equipped with tires which the bike’s manufacturer felt were the best balance of performance and value for the use for which the bike was intended. The tire size and pressure rating are marked on the sidewall of the tire. CAUTION: Pencil type automotive tire gauges and gas station air hose pressure settings can be inaccurate and should not be relied upon for consistent, accurate pressure readings. Instead, use a high quality dial gauge. WARNING: NEVER INFLATE A TIRE BEYOND THE MAXIMUM PRESSURE MARKED ON THE TIRE’S SIDEWALL. EXCEEDING THE RECOMMENDED MAXIMUM PRESSURE MAY BLOW THE TIRE OFF THE RIM, WHICH COULD CAUSE DAMAGE TO THE BIKE AND INJURY TO THE RIDER AND OTHERS. THE BEST WAY TO INFLATE A BICYCLE TIRE TO THE CORRECT PRESSURE IS WITH A BICYCLE PUMP. NEVER USE A SERVICE STATION AIR HOSE TO INFLATE A BICYCLE TIRE. IT IS DESIGNED FOR LARGER TIRES AND IT CAN EXCEED THE RECOMMENDED MAXIMUM PRESSURE AND IT MAY BLOW THE TIRE OFF THE RIM. Tire pressure is given either as maximum pressure or as a pressure range. How a tire performs under different terrain or weather conditions produces the harshest ride. High pressures work best on smooth, dry pavement. Very low pressures, at the bottom of the recommended pressure range, give the best performance on smooth, slick terrain such as hard-packed clay, and on deep, loose surfaces such as deep, dry sand. Tire pressure that is too low for your weight and the riding conditions can cause a puncture of the tube by allowing the tire to deform Some special high-performance tires have unidirectional treads: their tread pattern is designed to work better in one direction than in the other. The sidewall marking of a unidirectional tire will have an arrow showing the correct rotation direction. If your bike has unidirectional tires, be sure that they are mounted to rotate in the correct direction. 2. The tire valve allows air to enter the tire’s inner tube under pressure, but doesn’t let it back out unless you want it to. There are primarily two kinds of bicycle tube valves: The Schraeder Valve and the Presta Valve. The bicycle pump The Schraeder is like the valve on a car tire, this is the type of valve stem you should have on your bike. valve stem. To let air out of a Schraeder valve, depress the pin in the end of the valve stem with the end of a key or other appropriate object. 30 REFLECTORS , inspect onto your bicycle. Please refer to the following section for instructions on all types of WARNING! REFLECTORS ARE IMPORTANT SAFETY DEVICES WHICH ARE DESIGNED AS AN INTEGRAL PART OF YOUR BICYCLE. FEDERAL REGULATIONS REQUIRE EVERY BICYCLE TO BE EQUIPPED WITH FRONT, REAR, WHEEL, AND PEDAL REFLECTORS. THESE REFLECTORS ARE DESIGNED TO PICK UP AND REFLECT STREET LIGHTS AND CAR LIGHTS IN A WAY THAT HELPS YOU TO BE SEEN AND RECOGNIZED AS A MOVING BICYCLIST.

Your multi-speed bicycle will have a derailleur drivetrain (see 1. below), an internal gear hub drivetrain (see 2. below) or, in some special cases, a combination of the two. 1. How A Derailleur Drivetrain Works If your bicycle has a derailleur drivetrain, the gear-changing mechanism will have: – a rear cassette or freewheel sprocket cluster – a rear derailleur – usually a front derailleur – one or two shifters – one, two or three front sprockets called chainrings – a chain a. A Brief Note About Shifting Gears There are several different types and styles of shifting controls: levers, twist grips, triggers, combination shift/brake controls, pushbuttons, and so on. If you are not comfortable shifting gears, ask your local bike mechanic to explain the type of shifting controls that are on your bike, and to show you how they work. The vocabulary of shifting can be pretty confusing. A downshift is a shift to a “lower” or “slower” gear, one which is easier to pedal. An upshift is a shift to a “higher” or “faster”, harder to pedal gear. What’s confusing is that what’s happening at the front derailleur is the opposite of what’s happening at the rear derailleur (for details, read the instructions on Shifting the Rear Derailleur and Shifting the Front Derailleur below). For example, you can select a gear which will make pedaling easier on a hill (make a downshift) in one of two ways: shift the chain down the gear “steps” to a smaller gear at the front, or up the gear “steps” to a larger gear at the rear. So, at the rear gear cluster, what is called a downshift looks like an upshift. The way to keep things straight is to remember that shifting the chain in towards the centerline of the bike is for accelerating and climbing and is called a downshift. Moving the chain out or away from the centerline of the bike is for speed and is called an upshift. Whether upshifting or downshifting, the bicycle derailleur system design requires that the drive chain be moving forward and be under at least some tension. A derailleur will shift only if you are pedaling forward. CAUTION: Never move the shifter while pedaling backward, nor pedal backward immediately after having moved the shifter. This could jam the chain and cause damage to the bicycle. 33 b. Shifting The Rear Derailleur The rear derailleur is controlled by the right shifter. The function of the rear derailleur is to move the drive chain from one gear sprocket to another. The smaller sprockets on the gear cluster produce higher gear ratios. Pedaling in the higher gears requires greater pedaling effort, but takes you a greater distance with each revolution of the pedal cranks. The larger sprockets produce lower gear ratios. Using them requires less pedaling effort, but takes you a shorter distance with each pedal crank revolution. Moving the chain from a smaller sprocket of the gear cluster to a larger sprocket results in a downshift. Moving the chain from a larger sprocket to a smaller sprocket results in an upshift. In order for the derailleur to move the chain from one sprocket to another, the rider must be pedaling forward. c. Shifting The Front Derailleur The front derailleur, which is controlled by the left shifter, shifts the chain between the larger and smaller chainrings. Shifting the chain onto a smaller chainring makes pedaling easier (a downshift). Shifting to a larger chainring makes pedaling harder (an upshift). d. Which Gear Should I Be In? The combination of largest rear and smallest front gears is for the steepest hills; the smallest rear and largest front combination is for the greatest speed. It is not necessary to shift gears in sequence. Instead, nd the “starting gear” which is right for your level of ability (a gear which is hard enough for quick acceleration but easy enough to let you start from a stop without wobbling) and experiment with upshifting and downshifting to get a feel for the different gear combinations. At up your confidence. Learn to anticipate the need to shift, and shift to a lower gear before the hill gets too steep. If you have difficuties with shifting, the problem could be mechanical adjustment. See your local bike mechanic for help. WARNING! NEVER SHIFT A DERAILLEUR TO THE LARGEST OR THE SMALLEST SPROCKET IF THE DERAILLEUR IS NOT SHIFTING SMOOTHLY. THE DERAILLEUR MAY BE OUT OF ADJUSTMENT AND THE CHAIN COULD JAM, CAUSING YOU TO LOSE CONTROL AND FALL. WARNING! DO NOT FORCE THE SHIFT LEVERS. SHIFT ONLY WHEN PEDALING FORWARD AND WITHOUT STRONG FORCE. DO NOT BACKPEDAL. BACKPEDALING AND SHIFTING WHILE NOT PEDALING CAN DAMAGE THE SPROCKETS AND STRETCH THE CABLE WIRE. e. What If It Won’t Shift Gears? If moving the shift control one click repeatedly fails to result in a smooth shift to the next gear chances are that the mechanism is out of adjustment. Take the bike to your bike mechanic to have it adjusted. 34 2. How An Internal Gear Hub Drivetrain Works If your bicycle has an internal gear hub drivetrain, the gear changing mechanism will consist of: – one, or sometimes two shifters – one or two control cables~ one front sprocket called a chainring – a drive chain a. Shifting Internal Gear Hub Gears Shifting with an internal gear hub drivetrain is simply a matter of moving the shifter to the indicated position for the desired gear. After you have moved the shifter to the gear position of your choice, ease the pressure on the pedals for an instant to allow the hub to complete the shift. b. Which Gear Should I Be In? The numerically lowest gear (1) is for the steepest hills. The numerically largest gear depending on the number of speeds of your hub, is for the greatest speed. Shifting from an easier, “slower” gear (like 1) to a harder, “faster” gear (like 2 or 3) is called an upshift. Shifting from a harder, “faster” gear to an easier, “slower” gear is called a downshift. It is not necessary to shift gears in sequence. Instead, nd the “starting gear” for the conditions At rst, practice shifting where there are no obstacles, hazards or other traf c, until you’ve built up your con dence. Learn to anticipate mechanical adjustment. See your local bike mechanic for help. c. What If It Won’t Shift Gears? If moving the shift control one click repeatedly fails to result in a smooth shift to the next gear chances are that the mechanism is out of adjustment. Take the bike to your local bike mechanic to have it adjusted. 35 SHIFTING GEARS continued If your bike is equipped with STI shifting, please read the information below. • Lever B : Shifts from larger to smaller rear sprocket.

Properly maintaining your bicycle’s wheels will help braking performance and stability when riding. Be aware of the following potential problems: • Dirty or greasy rims: Caution: These can render your brakes ineffective. Do not clean them with oily or greasy materials. When cleaning, use a clean rag or wash with soapy water, rinse and air dry. Don’t ride while they’re wet. When lubricating your bicycle, don’t get oil on the rim braking surfaces. • Wheels not straight: Lift each wheel off the ground and spin them to see if they are crooked or out of true. If wheels are not straight, they will need • Broken or loose spokes: Check that all spokes are tight and that none are missing or damaged. Caution: Such damage can result in severe instability and possibly an accident if not corrected. Again, spoke repairs are best handled by a mechanic. • Loose hub bearings: Lift each wheel off the ground and try to move the wheel from side to side. Caution: If there is movement between the axle and the hub, do not ride the bicycle. Adjustment is required. • Axle nuts: Check that these are tight before each ride. • Quick release: Check that these are set to the closed position and are properly tensioned before each ride. Caution: Maintain the closed position and the correct adjustment. Failure to do so may result in serious injury. 40 MAINTENANCE & REPAIR WHEELS AND TIRES Tires must be maintained properly to ensure road holding and stability. Check the following areas: cause of tire failure. Due to the slightly porous nature of bicycle inner tubes, it is normal for your tires to lose Bead Seating: Tread: Caution: Excessively worn or damaged tires should be replaced. Valves: A slow leak caused by the entry of the dirt can Recommended Tire pressures: The recommended pressure molded on the sidewall of your bicycle tires should match the following chart. Use this as a general guide. BMx 35-50 p.s.i. MTB 40-65 p.s.i. Road Touring 70-90 p.s.i. Road Racing 110-125 p.s.i. Hybrid/Crossbike 60-100 p.s.i. 41 MAINTENANCE & REPAIR Tire Inspection If you need to repair a tire, follow these steps: 1. Remove the wheel from the bicycle. 3. Press one side of the tire bead up over the edge of the rim. Note: Use tire levers, not a screwdriver, otherwise you may damage the rim. 4. Remove the tube, leaving the tire on the rim. 5. Locate the leaks and patch using a tube repair kit or replace the tube. Note: Ensure that the replacement tube size matches the size stated on the tire sidewall and that the valve is the correct type for your bicycle. 6. Match the position of the leak in the tube with the tire to locate the possible cause and mark the location on the tire. 7. Remove the tire completely and inspect for a nail, glass, etc. and remove if located. Also inspect the inside of the rim to ensure there are no protruding spokes, rust or other potential causes. Replace the rim tape which covers the spoke ends. 8. Remount one side of the tire onto the rim. 9. Using a hand pump, inflate the tube just enough to give it some shape. 10. Place the valve stem through the hole in the rim and work the tube into the tire. Note: Do not let it twist. 11. Using your hands only, remount the other side of the tire by pushing the edge toward the center of the rim. Start on either side of the valve and work around the rim. 12. Before the tire is completely mounted, push the valve up into the rim to make sure the tire can sit squarely in position. Avoid using tire levers as these can easily puncture the tube or damage the tire. 14. Check that the tube is not caught between the rim and the tire bead at any point. 15. Using a hand pump, inflate the tube until the tire begins to take shape. Check that the tire bead is evenly seated all the way around the rim. When properly seated, fully inflate the tire to the pressure marked on the sidewall. 16. Replace the wheel into the frame checking that all gears, brakes and quick release levers are properly adjusted. 42 MAINTENANCE & REPAIR HOW TO FIx A FLAT TIRE Ball Bearings When checked, the hub bearings of either wheel will require adjustment if there is any more than slight side play. Bearing Cone Hub Body 1.Check to make sure neither locknut is loose. 2.To adjust, remove wheel from bicycle and loosen the locknut on one side of the hub open end wrench. 3.Rotate the adjusting cone as needed to eliminate free play. 4.Re-tighten the locknut while holding the adjusting cone in position. 5.Re-check that the wheel can turn freely without excessive side play. Axle Washer Lock Nut Axle Nut HEADSET INSPECTION The headset bearing adjustment should be checked every month. This is important as it is the headset which locks the fork into the frame, and if loose, can cause damage or result in an accident. While standing over the frame top tube with both feet on the Standard Headset Lock Nut any looseness in the headset, it will need adjustment. Check that the headset is not over tight by slowly rotating the fork to the right and left. If the fork tends to stick or bind at any point, the bearings are too tight. Note: for repairs and adjustments. Lock Washer ADjUSTMENT Ball Retainer Adjusting Cup/Cone Top Head Cup Note: Do not over tighten or bearing damage will occur. WARNING! ALWAYS MAKE SURE THAT THE HEADSET IS PROPERLY ADjUSTED AND THAT THE HEADSET LOCKNUT IS FULLY TIGHTENED BEFORE RIDING. WARNING! OVER TIGHTENING THE STEM BOLT OR HEADSET ASSEMBLY MAY CAUSE DAMAGE TO THE BICYCLE AND/OR INjURY TO THE RIDER. 43 MAINTENANCE & REPAIR HUB BEARING ADjUSTMENT MAINTENANCE & REPAIR Grip Shifters Grip Shift - Installation 1. Slide front Grip Shift assembly over left side of handlebar leaving proper clearance for handlebar grip. If necessary, move the brake lever to accommodate Grip Shift and handlebar grip. 2. Rotate assembly until cable exits beneath brake lever with adequate clearance for brake lever movement. 3. Firmly tighten recessed clamp screw. Installation torque should be 20 in.-lbs. 4. Slide the 7/8” plastic washer over handlebar. The washer prevents the grip from interfering with Grip Shift rotation. 5. Slide handlebar grip over handlebar. Thread the cable inner wire through cable housings and frame, and attach to derailleur. Make sure that the cable is in the V groove at the derailleur attachment bolt. If trimming the cable housing is necessary, be sure to replace the housing end cap. 6. Adjust indexing. 7. Slide rear Grip Shift over right side of handlebar and repeat steps 2 - 6. 8. Actuate front and rear brake levers to be certain of proper operation. If Grip Shift interferes with brake lever movement,rotate brake lever or Grip Shift. Check for proper brake lever operation again. 44 Cables and housing are one of the most overlooked parts on the bicycle. an increased amount of pressure needed to operate the brakes or shifters. Before every ride, check that there are no kinks or frays in the cables and housing. Check that the brake cables are correctly routed and not wrapped around the stem or frame in a manner that prevents smooth operation or hampers control of the bicycle. Also check that the housing is seated properly into each cable stop of the bicycle. It is recommended that the cables and housing are replaced at least every riding season to prolong the life of your bike. WARNING! DO NOT RIDE A BICYCLE THAT IS NOT OPERATING PROPERLY. WARNING! ALWAYS CHECK THE BRAKE CABLE ROUTING TO ENSURE SMOOTH AND FREE APPLICATION OF THE BRAKES. CABLES THAT ARE KINKED, FRAYED OR OTHERWISE DAMAGED, OR CABLES THAT ARE WRAPPED AROUND THE STEM OR FRAME MAY AFFECT BRAKING POWER OR CAUSE UNINTENDED SUDDEN STOPS AND LOSS OF CONTROL. 45 MAINTENANCE & REPAIR CABLES AND CABLE HOUSING The brake lever and brake caliper pivot points should be oiled with 2-3 drops of light oil at least every three months to ensure smooth operation and to reduce wear. Cables should be greased along their entire length, after removing them from their Cable Adjusting Barrel Lock nut Brake Lever ADjUSTMENT - SIDEPULL CALIPERS Minor brake adjustment can be made via the cable adjusting barrel, usually located at the upper cable arm. Caution: The brake cable adjusting barrels are for minor adjustments only. For major adjustments see the appropriate section in the manual for the type of brakes on your bicycle. To adjust, squeeze the brake pads against the rim, loosen the locknut and turn the adjuster. Brake pad clearance should be a maximum 2mm from the rim. When correct, retighten the lock nut. If the pads cannot be set close enough to the rim in this manner, you may have to adjust the cable length. Screw the barrel adjuster 3/4 of the way in, squeeze the pads against the rim, undo the cable anchor bolt and pull the cable through with pliers. Retighten the cable anchor bolt and apply full . If one pad is WARNING! ENSURE THE BRAKE FIxING NUT IS SECURED TIGHTLY.

There are several different types of derailleur systems but all ‘friction’ type system where you will need to feel each gear shift into position. Pre-stretch the derailleur cables to remove slack position to a positive click mechanism in the shifter, and makes shifting very simple and precise. INSPECTION The operation of the derailleur system should be checked at least every month. The rear derailleur should shift the chain cleanly from one cog to the next without hesitation. On Index System equipped bicycles, each notched position in the shifter must equate to a new gear position. After shifting, the rear derailleur should not rub on the chain. The derailleur should never cause the chain to fall off the inner or outer freewheel cogs. The front derailleur should also shift the chain cleanly and without hesitation between each chainring. When the chain has been positioned onto a new chainring, it should not rub on the front derailleur. The chain should not fall off a chainring at anytime. Derailleur control cables are a critical component that must be well maintained for accurate shifting performance. Check them for any sign of rust, fraying, kinks, broken strands, and any damage to the cable housing. If you 47 Stretch MAINTENANCE & REPAIR DERAILLEUR SYSTEMS 1. Shift the rear shifter to the smallest number indicated, then shift the front shifter to the smallest number indicated. Disconnect the front derailleur cable from the cable anchor bolt and place the chain on the smallest chainwheel. 2. Make sure the front chainguide is parallel with the outer chainwheel on the crankset. There must be a 3-5mm gap between the bottom of the derailleur cage and the top of the outer chainwheel teeth to ensure the derailleur will clear the chainwheel when shifting. Low Adjusting Screw Cable Anchor Bolt Outer Chainguide Inner Chainguide High Adjusting Screw Chainguide clearance of 3-5 mm 3. Adjust the low limit screw so the chain is centered in the middle of derailleur cage. Pull all slack out of the cable by pulling it taut, then reconnect the cable and tighten the cable anchor bolt securely. 4. Shift the front shifter into the largest gear and pedal the bike so the chain jumps to the largest chainwheel. If the chain does not shift onto the largest chainwheel, you will need to turn the High limit screw counter-clockwise until the chain moves to the largest chainwheel. If the chain falls into the pedals, the High limit screw has been turned too far. You will need to readjust the High screw clockwise in 1/4 turn increments until the chain no longer falls off. 5. Shift through each gear ensuring all are achieved quietly and without hesitation. Turn the adjusting barrel clockwise will move the derailleur outboard - away from the frame, while turning it clockwise will direct the chain inboard - towards the frame. NOTE: It may take several adjustments to achieve the desired positioning. 48 MAINTENANCE & REPAIR ADjUSTMENT - FRONT DERAILLEUR All the pivoting points of the front and rear derailleurs should be lubricated with light oil at least every month. Be sure to wipe off any excess oil to prevent attraction of dirt into the mechanisms. The shifting cables should be cleaned and re-coated with a thin layer of grease every six months, or whenever new cables are being installed. ADjUSTMENT - REAR DERAILLEUR The Low limit screw determines how far the rear derailleur will travel toward the wheel of the bicycle, while the High limit screw determines how far the cage will travel toward the frame. 1. Shift the rear shifter to the largest number indicated, disconnect the rear derailleur cable from the cable anchor bolt and place the chain on the smallest sprocket. 2. Adjust the High limit screw so the chain and the smallest sprocket are lined up vertically. Remove any slack in the cable by pulling it taut, then re-connect the cable and tighten the cable anchor bolt securely. 3. Some derailleurs have an adjusting barrel (see drawing). Use the adjusting barrel clockwise will move the derailleur outboard - away from the wheel - while turning it clockwise will direct the chain inboard - towards the wheel. 4. Shift the chain onto the largest sprocket; adjust the low limit screw so the chain and the largest cog are lined up vertically. If you are unable to get the chain to the largest cog, turning the Low limit screw counter-clockwise will enable the chain to move towards the wheel. 5. Shift through the gears ensuring each gear is achieved quietly and without hesitation. NOTE: It may take several adjustments to achieve the desired positioning. Please refer to the troubleshooting section for more assistance. NOTE: Some bicycles may be equipped with a rear derailleur mechanism that works in REVERSE to the directions above. 49 MAINTENANCE & REPAIR LUBRICATION Pedals are available in a variety of shapes, sizes and materials, and each are designed with a particular purpose in mind. Some pedals as downward pressure, on the pedals. Use of toe clips with straps requires practice to acquire the necessary skill to operate them safely. Inspection: Pedals should be inspected every month, taking note of the following areas: – Check that the pedals are tightened securely against the crank arm. If pedals are allowed to become loose, they will not only be dangerous but will also cause irreparable damage to the cranks. – Check that pedal bearings are properly adjusted. Move the pedals up and down, and right to left, and also rotate them by hand. If you detect any looseness or roughness in the pedal bearings then adjustment, lubrication or replacement is required. WARNING! Never ride with loose pedals. Always wear shoes. Lubrication and Adjustment: Many pedals cannot be disassembled to allow access to the internal bearings and axle. However, it is usually possible to inject a little oil onto the inside bearings, and this should be done every six months. If the pedal is the type that can be fully disassembled, then the bearings should be removed, cleaned and greased every six to twelve months. Because of the wide variety of pedal types and their internal complexity, disassembly procedures are beyond the scope of this manual and further assistance should be sought from a professional bicycle mechanic. Attachment Note: The right and left pedals of a bicycle each have a different thread and are not interchangeable. Never force a pedal into the incorrect crank arm. Check for the right (R) and left (L) letters on each pedal and crank arm. Match the appropriate pedal to each crank only. When the axle is screwed all the way in, securely tighten using a 15mm narrow open-ended wrench so that the shoulder of the pedal spindle is securely tightened against the crank arm. If removing a pedal, remember that the right pedal axle must be turned counter compatible with the cranks on your bicycle. Bicycles use one of two types of cranks and these use different axle threads. Your bike may be equipped with cranks that are a one piece design with no separate axle. These operate with pedals that have a 1/2”(12.7mm) thread. Bikes equipped with three piece crank sets with a separate axle, left crank and right crank, use a slightly larger 9/16”(14mm) thread. Note: Never try and force a pedal with the wrong thread size into a bicycle crank. 50 MAINTENANCE & REPAIR PEDALS Inspection: The chain must be kept clean, rust free and frequently lubricated in order to extend its life as long as possible. It will require replacement if it stretches, f links, they must all move freely. Lubrication The chain should be lubricated with light oil at least every month, or after use in wet, muddy, or dusty conditions. Take care to wipe off excess oil, and not to get oil on the tires or rim braking surfaces. Adjustment and Replacement On derailleur geared bicycles the rear derailleur automatically tensions the chain. To adjust the chain on single speed freewheel, fixed gear, coaster hub braked or 3-speed hub geared bicycles: in the frame. 2.When correctly adjusted, the chain should have approximately 10mm of vertical movement when checked in the center between the chainwheel and rear sprocket. Center the wheel in the frame and re-tighten the axle nuts after any adjustment. We recommend that you go to a local bicycle mechanic to replace or change the length of your chain. FREEWHEEL Inspection: Like the chain, the freewheel must be kept clean and well lubricated. If the chain has become worn and needs replacing, then it is likely that the freewheel will also have become worn and should also be replaced. Take the chain off the freewheel and rotate it with your hand. If you hear a grinding noise or the freewheel stops suddenly after spinning it, it may need adjustment or replacement. Such action is beyond the scope of this manual and you should consult a local bike mechanic. 51 MAINTENANCE & REPAIR CHAIN Remedy Possible Cause Gear shifts not working properly - Derailleur cables sticking/stretched/ damaged - Front or rear derailleur not adjusted properly - Indexed shifting not adjusted properly - Lubricate/tighten/replace cables - Adjust derailleurs - Adjust indexing Slipping chain - Excessively worn/chipped chainring or freewheel sprocket teeth - Chain worn/stretched-Stiff link in chain - Non compatible chain/chainring/freewheel - Replace chainring, sprockets and chain - Replace chain - Lubricate or replace link - Seek advice at a bicycle shop Chain jumping off freewheel sprocket or chainring - Chainring out of true - Chainring loose - Chainring teeth bent or broken -Rear or front derailleur side-to-side travel out of adjustment - Re-true if possible, or replace - Tighten mounting bolts - Repair or replace chainring/set - Adjust derailleur travel Constant clicking noises when pedaling - Stiff chain link - Loose pedal axle/bearings - Loose bottom bracket axle/bearings - Bent bottom bracket or pedal axle - Loose crankset - Lubricate chain / Adjust chain link - Adjust bearings/axle nut - Adjust bottom bracket - Replace bottom bracket axle or pedals - Tighten crank bolts Grinding noise when pedaling - Pedal bearings too tight - Bottom bracket bearings too tight - Chain fouling derailleurs - Derailleur jockey wheels dirty/binding - Adjust bearings - Adjust bearings - Adjust chain line - Clean and lubricate jockey wheels 52 TROUBLESHOOTING Problem Possible Cause Remedy Freewheel does not rotate - Freewheel internal pawl pins are jammed - Lubricate.

Frequently asked questions
The maximum weight limit for this tandem bicycle is 400lbs/181kg, including riders, luggage, and the bike itself.
Tandem bicycles are designed for use on public roads, paths, or tracks that are in good condition. They are not recommended for off-road use.
It is recommended to check your tandem bicycle regularly and perform required maintenance, such as checking brakes, tire pressure, and lubrication, before each ride.
It is important to communicate constantly between both riders, as the steering and stopping power are controlled by the front rider. Use caution when riding, as tandem bicycles can be more challenging to handle than single bikes.
