Setting Up the Handlebars2AssemblyNote: This procedure is for one, two andfour bolt Handlebar Stems.A1. If necessary, loosen the HandlebarClamp Screw(s) (A) and rotate Handlebar (2) into a comfortable riding position.2. Tighten Handlebar Clamp Screw(s) (A)securely.NOTE: Do not over tighten. Torque to 14-17ft-lbs.WARNING: If the handlebar clampin not tight enough, the handlebar can slipin the stem. This can cause damage to thehandlebar or stem, and can cause loss ofcontrol.fig 052Afig 05aA23124fig 05b14

Testing Stem and Handlebar Tightness Straddle the front wheel between your legs.Try to turn the front wheel by turning the handlebar.If the handlebar and stem turn without turning the front wheel, realign the stemwith the wheel and tighten the stem bolt(s) tighter than before (about 1/2 revolution only at a time).Do this test again, until the handlebar and stem do not turn without turning thefront wheel.AssemblyTo test the tightness of the stem:To test the tightness of the handlebar clamp: Hold the bicycle stationary and try to move the ends of the handlebar up anddown.CAUTION: Do not exceed 100 lbs downward force. If the handlebar moves, loosen the bolt(s) of the handlebar clamp.Put the handlebar in the correct position and tighten the bolt(s) of the handlebarclamp tighter than before.If the handlebar clamp has more than one bolt, tighten the bolts equally.Do this test again, until the handlebar does not move in the handlebar clamp.15

AssemblySeat InstallationAttach Seat to Seat Post:(pre-assembled on some models) Loosen nuts on seat clamp (A) androtate Seat (8) into riding position. Put the seat post (9) fully through theseat clamp (A). Tighten the Seat Clamp so the seatstays on the seat post. If the Seat Clamp has a nut on eachside, tighten both nuts equally.8A9fig 06CAUTION: If you accidentally drop the seat post into the seat tube, it may bedifficult to remove it. Point the Seat (8) forward and put theSeat Post (9) into the Seat Tube (B)(figs 07, 08).BB9WARNING: To prevent the seat coming loose and possible loss of control, the“MIN-IN” (minimum insertion) mark (C) onthe seat post must be below the top of theSeat Tube.C8Cfig 07Tighten the quick release lever: Move the Quick Release Lever (D) tothe “open” position so the word “open”is pointing away from the Seat PostClamp (E).NOTE: The words “open” and “close” are onopposite sides of the quick release lever.9FBEDfig 0816

Seat Installation - continuedYou must use strong force to move the quick release lever to the “close” position. Ifyou can easily move the lever to the “close” position, the clamping force is too light.WARNING: If the clamping force of the Quick Release Lever is too light, theseat post can loosen while riding. This can cause injury to the rider or to others.AssemblyCAUTION: Operate the Quick Release Lever by hand only. Do not use a hammer or any other tool to tighten the quick release lever.Tighten the quick release lever: Open and close the Quick Release Lever with one hand while you turn the Adjusting Nut (F) with the other hand (fig 08).Tighten or loosen the Adjusting Nut (F) by hand, so that you first feel resistanceto the quick release lever when it perpendicular to the bicycle frame.Push the Quick Release Lever to the “close” position (fig 08).When in the “close” position, make sure the Quick Release Lever lays againstthe Seat Post Clamp.The tightening torque of the Quick Release Lever should be tight enough so thatthe seat does not move during normal operation. Testing Seat Clamp and Post Clamp TightnessTo test the tightness of the seat clamp and the post clamp:WARNING: Every time the quick release mechanism is loosened, make surethe red reflector is correctly positioned (see page 16). Try to turn the seat side-to-side and to move the front of the seat up and down. If the seat moves in the Seat Clamp (A) (fig 06): Loosen the Seat Clamp.Put the seat in the correct position and tighten the Seat Clamp tighter thanbefore.Do this test again, until the seat does not move in the Seat Clamp.If the Seat Post (9) moves in the Seat Tube (B): Move the Quick Release Lever to the “open” position. Put the seat in the correct position and tighten the Quick Release Levertighter than before. If necessary, loosen Quick Release Lever, tighten Adjusting Nut and re-tightenQuick Release Lever. Do this test again, until the seat post does not move in the seat tube.17

Pedal InstallationAssemblyCAUTION: There is a right pedal marked “R” and a left pedal marked “L”. The pedal marked “R” has right-hand threads. Tighten it in a clockwise direction.The pedal marked “L” has left-hand threads. Tighten it in a counterclockwisedirection (anti-clockwise).Turn the right pedal marked “R” into the right side of the crank arm, and the leftpedal marked “L” into the left side of the crank arm.Tighten the pedals (fig 09): Make sure the threads of each pedal are fully into the crank arm. Make sure pedals are fully tightened with wrench.NOTE: The recommended torque (tightness) for each pedal is 30 ft.-lbs.LRfig 09Note: A Pedal Wrench is preferred for attaching Pedals. An open-endwrench can also be used as shown.WARNING: Ensure pedals are secure in crank arms so they will not loosen.Periodically check tightness.18

Reflector Brackets InstallationNOTE: Do not over-tighten. This willdamage the Clamp.Assembly1. Position FRONT Reflector (7) so itpoints straight forward (fig 10).2. Tighten Clamp Screw.7fig 101. Position REAR Reflector (10) so itpoints straight backward (fig 11).2. Tighten Clamp Screw.10fig 11NOTE: Do not over-tighten.

Brake SystemMaintenanceAdjustmentsWARNING: You must adjust the front and rear brakes before you ride thebicycle.Step 1: Put the brake shoes (B) in the correct position (fig 13):1. Loosen the Screw (A) of each Brake Shoe (B).2. Adjust each Brake Shoe so it is flat against the rim and aligned with the curve ofthe rim.3. Make sure each Brake Shoe does not rub the tire.4. If the surface of the Brake Shoe has arrows, make sure the arrows point towardthe rear of the bicycle.5. Hold each Brake Shoe in position and tighten the Screw.CBDAfig 13Step 2: Test the tightness of each Brake Shoe:1. Try to move each Brake Shoe out of position.2. If a Brake Shoe moves, do Step 1 again, but tighten the nut tighter than before.3. Do this test again, until each Brake Shoe does not move.20

Step 3. Stretching the cable (fig 13):1. Hold both Brake Shoes against the rim.2. Loosen the cable clamp Screw (C).3. Pull the Cable (D) tight and tighten the Screw.WARNING: Do not over tighten the cable clamp Screw. Over tightening thecable clamp Screw may cut the cable and cause injury to the rider or to others.MaintenanceBrake System - continued4. Squeeze each brake lever firmly 20 times.5. Hold both Brake Shoes against the rim and loosen the cable clamp Screw.6. Pull the Cable tight and tighten the cable clamp Screw.Final Brake Adjustment Before RidingThe following sections describe final brake system adjustments required before riding. Determine which style you have and follow the instructions.Check tightness of the cantilever mounting Bolt (A): Make sure each cantilever mounting Bolt is tightened securely.Center brake shoes on rim:1. Turn the Adjustment Screw (B) on the cantilever arm to move the arm in or out soeach Brake Shoe (C) is the same distance from the rim.2. Squeeze the brake lever two times.3. Do this step again, until both brake shoes are the same distance from the rim.fig 14CAB21

Final Brake Adjustment - continuedMaintenancePut the brake shoes the correct distance from the rim:1. If desired, adjust Brake Levers (G) to a comfortable distance from the grip usingthe Adjustment Screw (H). Turning the screw IN brings it closer to the grip.2. Make sure brake line Sheaths (A, B) are seated correctly.3. Position each Brake Shoe 1/16 inch away from the rim:4. Turn the caliper brake adjusting Screws (D) in or out to make the adjustment.5. If the brake shoes cannot be positioned the correct distance from the rim, holdboth Brake Shoes against the rim and loosen the cable clamp Screw (E)6. Squeeze the Brake Arms (F) together and pull or loosen the cable wire slightly.7. Tighten the cable clamp Screw.AEFDCG1/16”1/16”HB22fig 15

WARNING: Do not over tighten the cable clamp. Over tightening the cableclamp may cut the cable and cause injury to the rider or to others.8. Repeat these steps until the brake shoes are 1/16 inch from the rim and theBrake Lever (G) does not go all the way to the grip when squeezed (fig 15).WARNING: Do not move the brake shoes away from a wheel rim that is nottrue (straight). This can cause the caliper brake to be less effective and unsafe. To allow safe adjustment of the caliper brake, have a bicycle service shop true the wheel.MaintenanceFinal Brake Adjustment - continuedTest the tightness of the cable clamp (fig 15):1. Squeeze each Brake Levers (G) with firm pressure.2. Make sure the cable does not move in the Cable Clamp (E).3. If the cable moves in the cable clamp, adjust the brakes again but tighten thecable clamp tighter than before.4. Do this test again, until the cable does not move in the cable clamp.Test the travel of each brake lever:1. Squeeze each Brake Lever (G)with strong pressure2. If the brake lever touches the grip,adjust the brakes again.GWARNING: After you adjust the brakes again, if either brake lever touches thegrip or does not work well, have a bicycle service shop repair or adjust the brakes.23

MaintenanceNotes24

Shift System Left-hand Shift Lever (A) operates the Front Derailleur (B).Right-hand Shift Lever (C) operates the Rear Derailleur (D).Front Sprocket Set (E).Rear Sprocket Set (F).CAMaintenanceParts of the Shift System:FDBEOperation:Operate the shift system as follows:1. The rider turns the rear shift control around the handlebar (for twist shift models)or moves the shift lever (thumb shift models) to an index position2. When the rear shift control moves into each position with a “click” sound, the shiftis complete3. The rider turns the front shift control around the handlebar (for twist shift models)or moves the shift lever to an index position (thumb shift models)4. Each shift control pulls a cable wire that is attached to the derailleur.5. The derailleur moves and guides the chain from one sprocket to another.6. If there is some chain noise after the shift, turn the rear shift control a smallamount to “trim” the rear derailleur.25

MaintenanceShift System - continuedCAUTION: Do not force the shift levers. Shift only when pedaling forward andwithout strong force. Do not backpedal. Backpedaling can cause the chain to comeoff the sprockets. Backpedaling and shifting while not pedaling can damage thesprockets and stretch the cable wire.There is no “correct gear” in which to ride the bicycle. The “correct gear” is the onethat is comfortable to you.To select a gear or sprocket combination while riding:1. While pedaling, shift the chain onto different front and rear sprocket combinations.2. You will feel a difference in the rhythm and ease of pedaling.3. Shift the chain to the gear that allows you to pedal at a rhythm and effort that iscomfortable to you.4. When riding uphill or against the wind, you may wish to keep the chain on thesmallest front sprocket (A) and shift the chain on the rear sprocket cluster (B).BACfig 16These are the lower gear combinations.They allow you to pedal easier and at a faster rhythm, but with less distance traveledper pedal revolution.For the best performance in this case, do not use the smallest rear sprocket (C).When riding downhill or with the wind, you may wish to keep the chain on the largestfront sprocket (D) and shift the chain on the rear sprocket cluster.26

Shift System - continuedEMaintenanceThese are the higher gear combinations.Dfig 17They allow you to pedal harder and at a slower rhythm, but with more distance traveled per pedal revolution.For the best performance in this case, do not use the largest rear sprocket (E).On bicycles with three front sprockets, you may wish to keep the chain on the middlefront sprocket (F) and shift the chain on the rear sprocket cluster.Ffig 18These gear combinations are middle range which overlap some of the higher andsome of the lower gear combinations.27

MaintenanceFront Derailleur AdjustmentsThese instructions describe most adjustments that the shift system may need. If youcan not adjust the shift system using these instructions, have a bicycle service shopdo the adjustments that are needed.fig 19The left Grip (A) shifts the chain onthe front sprockets. The right Grip (B)shifts the chain on the rear sprockets.31234521A6CBThe front derailleur has two adjusting screws. The “low” adjusting screw, sometimesmarked “L”, limits how far the front derailleur and chain can move toward the frame.The “high” adjusting screw, sometimes marked “H”, limits how far the front derailleurand chain can move away from the frame.Put the “low” adjusting screw in the correct position as follows (fig 20): Shift the chain onto the third largest rear sprocket and the smallest front sprocket.Turn the lever Barrel Adjuster (C) (fig 19) all the way IN.Loosen Nut (D) of the cable clamp.Turn the “low” adjusting screw (E) so the left inside edge of the chain cage (F)and the chain (G) just do not touch.Remove the slack from the cable wire and tighten the Nut of the cable clamp.EDGHfig 2028F

Front Derailleur Adjustments Shift the chain onto the largest front sprocket and the smallest rear sprocket.Turn the “high” adjusting screw (E) so the right inside edge of the chain cage andthe chain just do not touch.NOTE: If the shift lever does not move easily: If the shift cable seems to stick, lubricate it.Do not lubricate the shift control.If the shift cable is sharply bent, rusted or has broken strands, replace it.MaintenancePut the “high” adjusting screw (E) in the correct position as follows:Perform the “Rear Derailleur Adjustments” if: The chain will not shift onto all the rear sprockets.The chain comes off the rear sprockets.The chain makes noise while on the smallest or largest rear sprocket.The rear derailleur rubs the spoke protector.29

MaintenanceRear Derailleur AdjustmentsThe rear derailleur has two adjusting screws. The “low” adjusting screw, sometimesmarked “L”, limits how far the rear derailleur and chain can move toward the wheel.The “high” adjusting screw, sometimes marked “H”, limits how far the rear derailleurand chain can move away from the wheel.123456ABfig 21Put the “high” adjusting screw in the correct position as follows: Shift the chain onto the smallest rear sprocket. Loosen Nut (C) of the cableclamp.Turn the lever Barrel Adjuster (A) and rear Derailleur Adjustor (B) all the way IN(fig 21).Turn the “high” adjusting Screw (G) so the Jockey Roller (D) is in line with theoutside edge of the smallest rear Sprocket (E) (fig 22).Remove the slack from the cable wire and tighten the Nut of the cable clamp.EDFC30GHfig 22

Rear Derailleur Adjustments Shift the chain onto the largest rear Sprocket (F).Loosen Nut of the cable clamp.Turn the “low” adjusting Screw (H) so the Jockey Roller is exactly below the largest rear sprocket.Tighten the Nut of the cable clamp.Adjust the Index Shift System (fig 23): MaintenancePut the “low” adjusting Screw in the correct position as follows:Shift the chain onto the smallest rear sprocket.Without turning the crank, turn the Right Shift Control (A) one “click” rearward.Slowly turn the crank forward.The chain should move from the smallest rear sprocket to the next larger rearsprocket.Turn the Adjusting Barrel (B) OUT as needed so the chain moves exactly on tothe second rear sprocket and does not rub, jump, or delay.312345216BAfig 23When adjusted properly, the shift system will operate smoothly with no chain rubbing.31

Three-Piece Cranks(various models)MaintenanceMaintenance:Both Crank Arms (A) were tightened to the spindle (B) at the factory. After riding thebicycle the first few times, make sure the crank arms have not loosened. If eithercrank arm has loosened during this “break-in” period, re-tighten or have it tightenedby a bicycle service shop.BAfig 24Frequently check the tightness of the crank arms. If loose, tighten or have them tightened by a bicycle service shop.WARNING: If you ride the bicycle with a loose crank arm, the crank arm mayfall off. The spindle may also damage the crank arm.NOTE: Torque crank arm nut to 395 in-lbs.32

Suspension Frame(various models)The bicycle may have an adjustable shock-absorbing suspension. You can changethe suspension, as you prefer, for a softer or a firmer ride.WARNING: Make sure there are at least two threads showing (C) above theAdjusting Nut (A) so the shock does not come loose.MaintenanceAdjustment:To change the suspension: For a softer ride, turn the Adjusting Nut (A) clockwise so the Suspension Spring(B) is compressed less.For a firmer ride, turn the Adjusting Nut (A) counter clockwise so the SuspensionSpring (B) is compressed
