EXTERNAL GEARS
Introduction
On gear systems with external gears the chain moves between the diff erent sprockets on the cassette.
You can count the number of gears on the bike by multiplying the number of sprockets on the rear
wheel cassette by the number of chain rings on the chainset. You can change the gear ratio by using
sprockets and chain rings with a diff erent number of cogs. The highest gear is obtained when the
chain lies on the large chain ring on the chainset and the smallest sprocket on the cassette. The
lowest gear is obtained when the chain lies on the small chain ring on the chainset and the largest
sprocket on the cassette. Thanks to the large number of gears you can ride in varying terrain and still
pedal at about 60 rpm.
Maintenance
All the parts of the gear system must be kept clean and regularly lubricated for the gears on the bike
to function properly for a long time.
Changing gear
The left-hand gear shift is used to switch between the chain rings on the chainset. The right-hand gear
shift is used to switch between the diff erent sprockets on the cassette. When the chain is on one of
the larger sprockets on the cassette you get a low gear, so that you can cycle on steep slopes. When
the chain is on one of the small sprockets on the cassette you get a high gear, so that you can cycle
faster and go down slopes. When the chain is on the small chain ring on the chainset you get a lower
gear than when it is on the large chain ring. Avoid shifting the chain to its outer position (large front
chain ring and large cassette sprocket/small front chain ring and small cassette sprocket). This avoids
unnecessary wear, noise and damage to the gear system.
IMPORTANT: Follow the instructions below when changing gear.
1.
Only change gear when the crank arms and wheels are moving forward.
2.
Do not change gear while pressing down hard on the pedals.
3.
Do not pedal backwards while changing gear.
4.
Do not force the gears.
5.
Change gear in good time (e.g. before an uphill slope), because you must pedal forward
when changing. Change down to a lower gear before you stop. This makes it easier to start
cycling again when you have a low gear. Change gear in good time when come to a steep
slope, so that you do not need to change when you press down hard on the pedals.
SIS adjustment
If the bike has Shimano SIS gears (with fi xed gear positions) you can preset the gear shift so that you
only need to click up or down to change gear. Adjusting the SIS gear shift is described on the follow-
ing pages. Your dealer may have already done the adjustments. Contact your dealer if you have any
problems adjusting the gear shift.
