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, find the “starting gear” for the 

conditions — 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 gears. At first, practice shifting where there 

are no obstacles, hazards or other traffic, until you’ve 

built 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  difficulties  with  shifting,  the 

problem could be mechanical adjustment. See your 

dealer 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 dealer to have it adjusted.

4.e - Pedals

1.   Toe Overlap is when your toe can touch the front 

wheel  when  you  turn  the  handlebars  to  steer 

while  a  pedal  is  in  the  forwardmost  position. 

This is common on small-framed bicycles, and is 

avoided by keeping the inside pedal up and the 

outside  pedal  down  when  making  sharp  turns. 

This technique will also prevent the inside pedal 

from striking the ground in a turn.

in Pedal oveRlaP.

Whether you have overlap or not, you must keep 

the inside pedal up and the outside pedal down 

when making sharp turns.

2.   Some bicycles come equipped with pedals that 

have  sharp  and  potentially  dangerous  surfaces.  

These    surfaces  are  designed  to  add  safety  by 

increasing  grip  between  the  rider’s  shoe  and 

the  pedal.  If  your  bicycle  has  this  type  of  high-

performance  pedal,  you  must  take  extra  care 

to  avoid  serious  injury  from  the  pedals’  sharp 

surfaces. Based on your riding style or skill level, 

you  may  prefer  a  less  aggressive  pedal  design, 

or chose to ride with shin pads. Your dealer can 

show you a number of options and make suitable 

recommendations.

3.   Toeclips  and  straps  are  a  means  to  keep  feet 

correctly  positioned  and  engaged  with  the 

pedals.  The toeclip positions the ball of the foot 

over  the  pedal  spindle,  which  gives  maximum 

pedaling power.  The toe strap, when tightened, 

keeps the foot engaged throughout the rotation 

cycle of the pedal.  While toeclips and straps give 

some  benefit  with  any  kind  of  shoe,  they  work 

most  effectively  with  cycling  shoes  designed 

for  use  with  toeclips.  Your  dealer  can  explain 

how toeclips and straps work.  Shoes with deep 

treaded soles or welts which might allow the foot 

to be trapped should not be used with toeclips 

and straps.

WhiCh  Can  only  Be  aCQUiRed  With 

PRaCtiCe. 

Until  it  becomes  a  reflex  action,  the  technique 

requires  concentration  which  can  distract  your 

attention and cause you to lose control and fall. 

Practice  the  use  of  toeclips  and  straps  where 

there are no obstacles, hazards or  traffic. Keep 

the  straps  loose,  and  don’t  tighten  them  until 

your technique and confidence in getting in and 

out of the pedals warrants it. Never ride in traffic 

with your toe straps tight.

4.  Clipless  pedals  (sometimes  called  “step-

in pedals”)  

are another means to keep feet 

securely  in  the  correct  position  for  maximum 

pedaling  efficiency.   They  have  a  plate,  called  a 

“cleat,” on the sole of the shoe, which clicks into a 

mating spring-loaded fixture on the pedal.
