16 F. Downhill or Com petition Biking If you ride downhill at spee d or in co mpetition, you volu ntarily assume an incr eased risk of injury or d eath. When riding down hill, you ca n reach spe eds seen on mo torcycle s, and therefore face simil ar ha zards and risks.
17 3. Fit W A R N I N G : C o r r e c t f i t i s a n e s s e n t i a l e l ement of bicycling sa f ety, performance and comfort. Ma king the adjustme nts to your bicycl e which result in correct fit for your body and riding c onditions requires experience, s kill a nd special tools.
18 1. Up and Do wn Adjustment. Check for correct saddle height (fig. 3): • sit on the saddle; • place one heel on a pedal; • rotate the crank until the pedal with your heel on it is in the down position and the crank arm is parallel to the seat tube.
19 WARNING: After any saddle adju stment, be sure that the sa ddle adjusting mechanism is properly tightened be fore riding. A loose saddle cla mp or seat po st binder can cause damage to the seat post, or can cause you to lose control and fall. A correctly tightened saddle adjustin g mechanism will allow no saddle movement in any direction.
20 WARNING: On some bicycles, ch anging the stem or s tem height ca n affect the tension of the front brake cable, l ocking the front brake or creating excess cable slack which can make the front brake inoperable.
21 4. Tech It’s important to your safety, performance and enj oyment to understa nd how things work on your bicycle. If you have even the slightes t doubt as to whether you understand something in this section of the Manual, talk to your dealer. A. Wheels 1.
22 Secondary retenti on devices fall int o two basic categori es: a. The clip-on type is a part the m anufac turer a dds to th e fr ont wheel hub or front fork. b. The integral type is m olded, cast or machined into the outer fa ces of the front fork d ropouts.
23 WARNING: The full force of the cam action is needed to clamp the wheel securely. Holdin g the nut with one hand and turnin g the lever like a wing nut with the other hand until everything is as tight as you can get it will no t clamp the wh ee l safely in the drop outs.
24 (5) If the lever cannot be pushed a ll the way to a position parallel to the fork blade, return the lever to the OPEN position. Then turn the te nsion-adjustin g nut counterclock wise one-quarter turn and try tightening the lever again.
25 (5) Tighte n the quick-release adjusting nut until it is finger tight against the fr ame dropout; then swing the lever toward the front of the bike un til it is parallel to the frame’s chai nstay or seatstay and is curv ed toward the wheel (fig. 7b).
26 (3) If your front fork has a clip- on type secondary rete ntion device, disengage it an d go to he ne xt st ep . I f your front fork has an integral se condary retenti on device, loosen t he axle nuts enough to allow wheel removal ; then go to the ne xt step.
27 WARNING: If your bike is equipped with an internal gear rear hub, do not atte mpt to re move the rea r wheel. T he removal and r e-installation of internal gear hubs require sp ec ial knowledge. Incorrect removal or assembly c an result in h ub failure , which can ca use yo u to lose cont rol and fall.
28 Adjusting the seat post quick release mech anism. The action of the quick rele ase cam squeezes the seat colla r around the seat pos t to hold the seat post sec urely in place.
29 Brakes are designed to control your speed, not jus t to stop the bike. M aximum braking force for each wheel occ urs at the poin t just before the wh eel “locks up ” (stops rota ting) and starts to skid. Once the tire skids, yo u actually lose most of y our st opping force and all directional control .
30 other hazards and dis tractions. Everyt hing changes when you ri de on loos e surfaces or in wet weather. Tire adhesion is reduced, so the wheels ha ve less cor nering and braking traction and can lock up with less brake force. Moisture or dirt on the brake pads reduces their ability to grip .
31 1. How a Derailleur Drive train Wor ks a. Parts of the Drivetrai n. If your bi cycle has a derailleur drivetrai n, the gear- changing mechanism will have: (1) a rear cassette or freewheel sprocket clus ter (2) a rear derailleur (3) usually a front derailleur (4) one or two shifters (5) one, two or three front sp rockets c alled chainrings b.
32 CAUTION: Never move the shifter while pedaling backward, nor pedal backwards after having moved the shifter. This could jam the chain and cause serious damage to th e bicycle. c. Shifting the Rear Derailleur. The rear dera illeur is controlled by the right shifter.
33 At first, practi ce shifting where t here are no obstacles, ha zards or ot her traffi c, until you’v e built u p your confidence. If you have difficul ti es with shifting, the pr oblem could be mechanical adjustment. See your dealer for help. 2. How an Internal Gear Hub Drivetra in Works.
34 E. Ped als Some higher performance bicycles c ome equipped wit h pedals that ha ve sharp a nd potenti ally dange rous sur faces. These surfaces are designed to add safety by increasing adhesion between the rider’s s hoe and the pedal.
35 WARNING: Getting into and out of pedals with toeclips and straps requ ires skill which can only be acquired with practice. U ntil it becomes a reflex action, the technique requires concentration which can distract the r ider’s attention, causing you to lose c ont rol and fall.
36 F. Bicycle Suspension WARNING: Failure to maintain, check and properly adjust the su spen sion system may result in suspensi on malfunct ion, which may c a use you to lose control and fall. WARNING: Changing susp ension adjust ment can change the hand ling and braking characteristics of your bicycle.
37 G. Tires and Tubes 1. Tire s . Bicycle tires are avail able in many de signs and spec ifications, ranging from general-purpose designs to ti re s designed to perform best under very specific weather or terrain conditions.
38 WARNING: Never inflate a tire beyond the maximum pressure ma rked on the tire’s sidewall. Exceedi ng the recommended m aximum pressur e may blow the tire off the rim, whic h could cause damage to the bike and injury to the ride r and bystanders.
