Setting Up the Handlebars 2 Assembly Note: This procedure is for one, two and four bolt Handlebar Stems. A 1. If necessary, loosen the Handlebar Clamp 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 14-17 ft-lbs. WARNING: If the handlebar clamp in not tight enough, the handlebar can slip in the stem. This can cause damage to the handlebar or stem, and can cause loss of control.
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 stem with 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 the front wheel.
Assembly Seat Installation Attach Seat to Seat Post: (pre-assembled on some models) • Loosen nuts on seat clamp (A) and rotate Seat (8) into riding position. • Put the seat post (9) fully through the seat clamp (A). • Tighten the Seat Clamp so the seat stays on the seat post. • If the Seat Clamp has a nut on each side, tighten both nuts equally. 8 A 9 fig 06 CAUTION: If you accidentally drop the seat post into the seat tube, it may be difficult to remove it.
Seat Installation - continued You must use strong force to move the quick release lever to the “close” position. If you 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, the seat post can loosen while riding. This can cause injury to the rider or to others. Assembly CAUTION: Operate the Quick Release Lever by hand only. Do not use a hammer or any other tool to tighten the quick release lever.
Pedal Installation Assembly CAUTION: 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 counterclockwise direction (anti-clockwise). Turn the right pedal marked “R” into the right side of the crank arm, and the left pedal marked “L” into the left side of the crank arm.

Tighten Clamp Screw. 7 fig 10 1. Position REAR Reflector (10) so it points straight backward (fig 11). 2. Tighten Clamp Screw. 10 fig 11 NOTE: Do not over-tighten. This will damage the Clamp. Installing Derailleur Guard (on some models) 1. 2. 3. 4. Remove Screws (11) from Frame Tabs (A). Install Guard (12) using two Screws (11).
Brake System Maintenance Adjustments WARNING: You must adjust the front and rear brakes before you ride the bicycle. 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 of the 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 toward the rear of the bicycle. 5.
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 the cable clamp Screw may cut the cable and cause injury to the rider or to others. Maintenance Brake System - continued 4. Squeeze each brake lever firmly 20 times. 5. Hold both Brake Shoes against the rim and loosen the cable clamp Screw. 6.
Final Brake Adjustment - continued Maintenance Put the brake shoes the correct distance from the rim: 1. If desired, adjust Brake Levers (G) to a comfortable distance from the grip using the 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.
WARNING: Do not over tighten the cable clamp. Over tightening the cable clamp 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 the Brake 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 not true (straight). This can cause the caliper brake to be less effective and unsafe.
Maintenance Notes 24
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). C A Maintenance Parts of the Shift System: F D B E Operation: 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 position 2.
Maintenance Shift System - continued CAUTION: Do not force the shift levers. Shift only when pedaling forward and without strong force. Do not backpedal. Backpedaling can cause the chain to come off the sprockets. Backpedaling and shifting while not pedaling can damage the sprockets and stretch the cable wire. There is no “correct gear” in which to ride the bicycle. The “correct gear” is the one that is comfortable to you. To select a gear or sprocket combination while riding: 1.
Shift System - continued E Maintenance These are the higher gear combinations. D fig 17 They 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 middle front sprocket (F) and shift the chain on the rear sprocket cluster.
Maintenance Front Derailleur Adjustments These instructions describe most adjustments that the shift system may need. If you can not adjust the shift system using these instructions, have a bicycle service shop do the adjustments that are needed. fig 19 The left Grip (A) shifts the chain on the front sprockets. The right Grip (B) shifts the chain on the rear sprockets. 3 1 2 3 4 5 2 1 A 6 C B The front derailleur has two adjusting screws.
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 and the 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.
Maintenance Rear Derailleur Adjustments The rear derailleur has two adjusting screws. The “low” adjusting screw, sometimes marked “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 derailleur and chain can move away from the wheel. 1 2 3 4 5 6 A B fig 21 Put the “high” adjusting screw in the correct position as follows: • • • • Shift the chain onto the smallest rear sprocket.
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): • • • • • Maintenance Put the “low” adjusting Screw in the correct position as follows: Shift the chain onto the smallest rear sprocket.
Three-Piece Cranks (various models) Maintenance Maintenance: Both Crank Arms (A) were tightened to the spindle (B) at the factory. After riding the bicycle the first few times, make sure the crank arms have not loosened. If either crank arm has loosened during this “break-in” period, re-tighten or have it tightened by a bicycle service shop. B A fig 24 Frequently check the tightness of the crank arms. If loose, tighten or have them tightened by a bicycle service shop.
Suspension Frame (various models) The bicycle may have an adjustable shock-absorbing suspension. You can change the suspension, as you prefer, for a softer or a firmer ride. WARNING: Make sure there are at least two threads showing (C) above the Adjusting Nut (A) so the shock does not come loose. Maintenance Adjustment: To change the suspension: • • For a softer ride, turn the Adjusting Nut (A) clockwise so the Suspension Spring (B) is compressed less.
Maintenance Tires Maintenance: • Frequently check the tire inflation pressure because all tires lose air slowly over time. For extended storage, keep the weight of the bicycle off the tires. • Do not use unregulated air hoses to inflate the tire/tubes. An unregulated hose can suddenly over inflate bicycle tires and cause them to burst. • Replace worn tires. WARNING: Do not ride or sit on the bicycle if a tire is under inflated. This can damage the tire, inner tube and rim.
• WARNING: Inspect the bicycle frequently. Failure to inspect the bicycle and to make repairs or adjustments, as necessary, can result in injury to the rider or to others. Make sure all parts are correctly assembled and adjusted as written in this manual and any “Special Instructions”. • Immediately replace any damaged, missing, or badly worn parts. • Make sure all fasteners are correctly tightened as written in this manual and any “Special Instructions”.
Lubrication Table Maintenance What How Pedals every six months Put four drops of oil where the axles go into the pedals. Chain every six months Put one drop of oil on each roller of the chain. Wipe all excess oil off the chain. Shift Levers never Derailleurs every six months Put one drop of oil on each pivot point of the derailleurs. Brake Levers every six months Put one drop of oil on the pivot point of each brake lever.
Maintenance Frequently check the bearings of the bicycle. Have a bicycle service shop lubricate the bearings once a year or any time they do not pass the following tests: Head Tube Bearings The fork should turn freely and smoothly at all times. With the front wheel off the ground, you should not be able to move the fork up, down, or side-to-side in the head tube. Crank Bearings The crank should turn freely and smoothly at all times and the front sprockets should not be loose on the crank.
