danger of an accident!

Shifting gears under load, i.e. while pedalling hard, can
make the chain slip. At the front derailleur the chain could
even slip off the chainrings and result in an accident! At the
very least the service life of the chain would be reduced
considerably.

Avoid gears which involve an extremely oblique run of the
chain, as this will increase wear!

It is crucial when switching gears to continue pedalling
smoothly and without too much force. Do not shift under
load, and in particular not at the front derailleur
(b)
, as this
will shorten the service life of your chain considerably. Fur-
thermore, this can lead to a chain-suck, i.e. the chain can
get jammed between chain stay and chainrings.
Checking and Readjusting
The derailleur gears of your bicycle were carefully adjusted by your
WHEELER bicycle dealer before delivery
(c)
. However, Bowden cables
may stretch a little over the first kilometres, making gear shifting impre-
cise and the chain rattle.
Adjusting the front and rear derailleur
(d)
accurately is a job only for
an experienced mechanic. If you wish to attempt this yourself, follow in
addition the operating instructions of the gear manufacturer, which you
can find on the enclosed CD. Contact your WHEELER bicycle dealer if
you have any problems with the gears.
I
For your own safety, bring your WHEELER bicycle to your
WHEELER bicycle dealer for its first inspection after 100
to 300 kilometres (60 to 180 miles), 5 to 15 hours of initial
use or four to six weeks, and at the very latest after three
months.
Adjusting the Rear Derailleur
Increase the tension of the Bowden cable by turning the adjustable
cable stop at the shifter lever
(e)
or the adjusting bolt through which it
runs into the rear derailleur
(f)
. To do so, shift to the smallest sprocket
and turn the bolts anticlockwise in half turns until the cable is slightly
tensioned.
After tensioning the Bowden cable check whether the chain immedi-
ately climbs onto the next larger sprocket. To find out you either have
to turn the cranks by hand
(g)
or ride the WHEELER bicycle and shift
through the gears.
If the chain easily climbs onto the next larger sprocket, check whether
it just as easily shifts to the small sprockets. If it does not, release the
respective adjusting bolt a little. You may need several tries.

Adjusting the front and rear derailleur accurately is a job
for an experienced mechanic. Comply also with the instruc-
tions of the gear manufacturer, which you can find on the
enclosed CD. Contact your WHEELER bicycle dealer if you
have any problems with the gears.
I
Ask a helper to lift the rear wheel. By turning the cranks and
shifting through you can easily check the function.
Adjusting the Limit Stops
The rear derailleur is equipped with limit screws
(h)
which limit the
movement range of the derailleur, thus preventing the derailleur and
chain from colliding with the spokes or the chain from dropping off
the smallest sprocket. The limit screws are adjusted by your WHEELER
bicycle dealer. They do not alter their position during normal use.
If necessary, correct the position by means of the limit screws. The
limit screws on rear derailleurs are often marked “H” for high gear and
“L” for low gear. “High gear” means that the chain is running on the
smallest sprocket. Turn the screw clockwise to shift the rear derailleur
towards the wheel and anticlockwise to shift it away from the wheel.
Shift to the biggest (inmost) sprocket and check whether the teeth of
the sprocket and the teeth of the guide pulley are all in a perfectly
vertical line. Turn the limit screw marked “L” clockwise until the rear
derailleur stops moving towards the spokes and can neither be moved
by actuating the shift lever nor by pushing it with your hand.
