Bar End Shifters
In the case of the
Shimano
,
SRAM
and
Campagnolo
bar end shifters
for
triathlon and time trial use you must press down the shifter to shift to the smaller
sprockets, i.e. to a high gear ratio, and to the smaller chainrings, i.e. to a lower
gear ratio. By pulling the shifter upwards you can shift to the larger chainrings or
sprockets.
Flatbar Shifters
In the case of
flat bars the control levers
of the shifters are positioned under
the handlebar. The big lever on the right is thumb-operated. The chain moves
on larger sprockets, i.e. to lower gears. The smaller lever is either index finger
or thumb-operated and shifts into the other direction. On the left side the big
thumb-operated lever shifts to the large chainring, i.e. to a higher gear ratio.
With
SRAM AXS
, i.e. the electronic brake levers/shifters, actuating the right
shifter makes the rear derailleur move the chain outwards, i.e. towards the smaller
sprockets or the higher gears. However, by pressing the left shifter the rear derail-
leur shifts towards the larger sprockets.
Danger:
Shifting gears under load, i.e. while pedalling hard, can make the chain
slip. At the front derailleur the chain may even slip off the chainrings and
result in an accident! At least the service life of the chain will be shortened
considerably.
Danger:
Practise switching gears in a place free of traffic until you are familiar
with the functioning of the brake lever/shifter units or the shifters of your
bicycle.
Note:
The gear manufacturers usually deliver their products with detailed instruc-
tions. Read them thoroughly. Make yourself familiar with your new gears
in an area free of traffic, if necessary. If you are in doubt or if you have any
questions, contact your STEVENS dealer.
Caution:
If there is play between
bearing shaft and
cranks, they can
sustain damage. Risk of
breakage!
Caution:
Avoid gears which
involve an extremely
oblique run of the chain.
as this will increase
wear!
Danger:
For your own safety,
bring your newly pur-
chased STEVENS bicycle
to the STEVENS dealer
for its first service after
100 to 300 kilometres
(60 to 180 miles), 5 to
15 hours of use or four
to six weeks, at the very
latest, however, after
three months.
Checking and Readjusting the Gears
The derailleur gears of your the STEVENS bicycle were carefully adjusted by
your STEVENS dealer before delivery. The Bowden cables may, however, give way
or compress the cable housings on the first kilometres making gear changing
imprecise. This will result in the chain not wanting to climb onto the next smaller
sprocket.
Rear Derailleur
In the case of imprecise shifting increase the tension of the Bowden cable by
turning the adjusting bolt through which it passes at the entry to the shift lever or
rear derailleur. To do so, shift to the smallest sprocket and turn the clicking bolts
anticlockwise in half turns until the cable is slightly tensioned.
After tensioning the Bowden cable check whether the chain readily climbs onto
the next larger sprocket. To find out you either have to turn the cranks by hand or
ride the STEVENS bicycle.
If the chain readily climbs onto the next larger sprocket, check whether it also
readily shifts to the small sprockets when you change to a higher gear. You may
need several tries to get the derailleur system properly adjusted.
Adjusting the Limit Stops
The rear derailleur is equipped with limit screws which limit the swivel range of
the rear derailleur, thus preventing the rear derailleur and chain from colliding with
the spokes or the chain from dropping off the smallest sprocket. The limit screws
are adjusted by your STEVENS dealer. They do not alter their position during
normal use. After a fall you should however always check the proper adjustment.
Shift with the right shifter to the highest gear. The inner cable is then totally
relaxed and the chain will run on the smallest sprocket. Look from the rear of the
bicycle at the cassette and check whether the teeth of the smallest sprocket and
the teeth of the guide pulley are all in a perfectly vertical line.
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. In this
case high gear stands for high transmission ratio, i.e. with the chain running on
the smallest sprocket.
Caution:
If your STEVENS bicycle has tipped over or the rear derailleur received a
blow, the rear derailleur or its mount may be bent. It is advisable to check
its range of movement and readjust the limit screws, if necessary, after
such an incident or after mounting new wheels on your STEVENS bicycle.
