Operation Manual
With the gear and brake lever components, the
brake lever has to be pushed downward to shift to the smaller sprockets
and larger chainrings. Pulling the lever upward or actuating the small thumb
shifter located under the handlebars, will give you a larger sprocket and a
smaller chainring, both leading to a lower gear.
Pressing the large shifting lever of located under
the handlebars with your thumb, shifts the chain to the larger chainrings and
larger sprockets. The smaller shifter, also located under the handlebars, but
a bit higher than the big one, is pushed with the thumb, too, and makes the
chain move to the smaller chainrings and smaller sprockets.
The principle of is different . Twisting the right-hand grip to-
wards you moves the chain to a larger sprocket giving you a lower gear,
while the same movement on the left produces a higher gear by moving the
chain to the larger chainrings. The shifting direction may vary in this case,
as well.
Practise switching gears in a place free of traffic until you are
familiar with the functioning of the levers or twist grips of your
bicycle.
It is therefore crucial when switching gears to continue pedal-
ling smoothly and without too much force. Do not shift under
load, as this will shorten the durability of the chain considerably.
Furthermore, this can lead to a chain-suck, i.e. the chain can
get jammed between chain stay and chainrings. Avoid shifting
gears while pedalling with force, in particular when shifting with
the front derailleur.
Avoid gears which involve an extremely oblique run of the chain,
as this will increase wear.
On classic road racing bicycles the shifting levers are integrated with the
brake lever.
On a equipped bicycle, moving the small lever
located behind the brake lever inward with your index or middle finger, shifts
the chain towards the larger sprockets. Pressing the lever inside the brake
hood with your thumb, shifts the chain to the smaller sprockets. By pressing
once you can shift up to three sprockets.

With levers , swivelling the entire brake lever in-
ward shifts the chain towards the larger sprockets. Up to three sprockets
can be shifted per tap. Moving the small lever alone that is located behind
the brake lever the chain moves towards the smaller sprockets, but only one
sprocket per tap.
levers have only one shifting lever positioned behind
the brake lever. Tapping the lever to its end shifts the gear one to three
sprockets higher. A short tap moves the chain to the next smaller sprocket.
With and bar end shifters for triathlon
and time trial use the shifting lever is pressed downward to move the chain
to the smaller sprockets to achieve a higher gear and to the smaller chain-
rings to achieve a lower gear. By pulling the shifting lever upward you can
switch to the larger sprockets and larger chainrings.
The are located underneath the handle-
bars. By shifting the right big lever with the thumb the chain moves to larger
sprockets, i.e. in a lower gear. The smaller lever is shifted with the index
finger or thumb and switches in higher gears. By operating the big shifter
with the thumb on the left side the chain moves to the larger chainring, i.e.
to a higher gear.
With the and swivelling the entire brake lever in-
ward, shifts the chain towards the larger sprockets. Pushing the lever inside
the brake hood with your thumb shifts the chain to the smaller sprockets.
