KONA OWNER’S MANUAL

• a rear derailleur

• occasionally a front derailleur

• one or two shifters

• one, two or three front sprockets called chainrings

• a drive chain

A) Shifting Gears

There are several different types and styles of shifting con-

trols: levers, twist grips, triggers, combination shift/brake

controls and push-buttons. Ask your dealer to explain the

type of shifting controls that are on your bike, and to show

you how they work.

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 the bicycle.

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. 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 pedal-

ing easier. Shifting to a larger chainring makes pedaling

harder.

When you apply one or both brakes, the bike begins to slow,

but your body wants to continue at the speed at which it was

going. This causes a transfer of weight to the front wheel

(or, under heavy braking, around the front wheel hub, which

could send you ying over the handlebars).

A wheel with more weight on it will accept greater brake

pressure before lockup; a wheel with less weight will lock up

with less brake pressure. So, as you apply brakes and your

weight is transferred forward, you need to shift your body

toward the rear of the bike, to transfer weight back on to the

rear wheel; and at the same time, you need to both decrease

rear braking and increase front braking force. This is even

more important on descents, because descents shift weight

forward.

Two keys to effective speed control and safe stopping are

controlling wheel lockup and weight transfer. This weight

transfer is even more pronounced if your bike has a front sus-

pension fork. Front suspension “dips” under braking, increas-

ing the weight transfer (see also Section 4.F). Practice brak-

ing and weight transfer techniques where there is no trafc or

other hazards and distractions. Everything changes when you

ride on loose surfaces or in wet weather. It will take longer to

stop on loose surfaces or in wet weather. Tire adhesion is re-

duced, so the wheels have less cornering and braking traction

and can lock up with less brake force. Moisture or dirt on the

brake pads reduces their ability to grip. The way to maintain

control on loose or wet surfaces is to go more slowly.

D) SHIFTING GEARS

Your multi-speed bicycle will have a derailleur drivetrain.

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
