Don’t ride a bike with badly adjusted gears. If you can’t rely on finding the right gear
every time, if the chain keeps jumping off or you’re stuck in a high gear, it’s only too
easy to lose control.
AND REMEMBER:
Bottom and the rest of the low gears are for
climbing hills. Top and the other high gears are for descents.
At the rear wheel, the small sprocket is top gear, the large sprocket is bottom.
The idea of a rotary changer is to allow
you to change gear with a simple wrist
movement. When changing up, take
a firm grip on the inboard end of the
hand grip drop your wrist, clicking the
changer once for every gear that you
want to change through on the right.
The LH may be a friction shifter.
To change down, lift your wrist and
then grasp the rotary part of the hand
grip. Then click down quickly but
smoothly. However, if you want to
change from top to near bottom gear,
it’s best to do it in two stages, pausing
a second half way.

Using the small
chainring and small
sprocket together
causes excessive
chain crossover . . .
. . . as does using
the big chainring
with the biggest
sprocket. Use these
gear combinations
as little as possible,
otherwise the chain
and sprockets will
wear out faster than
they should.
