In the case of shifters pressing the large shifter (thumb
shifter) moves the chain towards the larger chainwheels/
sprockets.
That means that any gear shift made by pressing the
large thumb shifter on the right produces a lower gear.
This is an indexed shifting system with the option of
shifting several gears with one action. Actuating the
large thumb shifter on the left produces a higher gear.
Pulling the small lever
(a)
located in front of the han-
dlebars from the rider’s viewpoint and actuated with the
index finger (index finger lever) shifts the chain towards
the smaller chainwheels/sprockets, i.e. on the right side
to the higher gears and on the left side to the lower gears.

Read in any case carefully the operating in-
structions of the gear manufacturer on this
MERIDA CD-ROM. Make yourself familiar
with your new gears in an area free of traffic, if neces-
sary. If you are in doubt or if you have any questions,
contact your MERIDA dealer.
The principle of twist grips is different
(b)
. Turning the
right-hand grip towards you makes for a lower gear ra-
tio, while the same movement on the left produces a
higher gear – and vice versa. The shifting direction may
vary in this case, as well.

Always wear straight-cut trousers or use trou-
ser clips
(c)
or the like. To make sure your
trousers do not get caught in the chain or the
chainwheels. Risk of an accident!

Shifting gears under load, i.e. while pedaling
hard, can make the chain slip. At the front de-
railleur the chain may even slip off the chain-
wheels and result in an accident! At the very least the
service life of the chain would be reduced considerably.

If there is play between bearing spindle and
cranks, they can sustain damage. Risk of
breakage!
A
Avoid gears which involve an extremely
oblique run of the chain as this will increase
wear!

It is crucial when switching gears to contin-
ue pedaling smoothly and without too much
force. Do not shift under load, and in particu-
lar not at the front derailleur, as this will shorten the ser-
vice life of your chain considerably. Furthermore, this
can lead to a chain-suck, i.e. the chain can get jammed
between chain stay and chainwheels.
