ADjUSTInG THE TILT oF THE HAnDLEBARS, BAR EnDS AnD
BRAKE LEVERS
b
The handlebars of city, trekking and children's bikes are usually slightly
bent at the ends. Set the handlebars to a position in which your wrists
are relaxed and not turned too much outwards (c).
To adjust the angle of the handlebars, release the Allen bolt(s) on the
underside or front side of the stem. Turn the handlebars to the desired
position. Make sure the handlebars are accurately centred in the stem
(d). Now carefully retighten the bolt(s) with a torque wrench.
Try rotating the handlebars once clamped in the stem and tighten the
c
bolt a little more, if necessary. Use a torque wrench and never exceed
the maximum torque values! You can find these in the chapter "rec-
ommended torque Settings for components", on the components
themselves and/or in the instructions from the parts manufacturers,
which you can find on the enclosed CD.
After adjusting the handlebars you need to adjust the brake and shift
lever mounts.
Release the Allen bolt at either mount. Turn the levers relative to the
handlebars. Sit in the saddle and place your fingers on the brake levers.
d
Check whether the back of your hand forms a straight line with the line
of your forearm. Retighten the mounts with a torque wrench and do a
twist test!

In the case of turned stems, it is possible that the cables
are too short. In this case riding can be unsafe. Ask your
WHEELER bicycle dealer for help.
When removing spacers the fork steerer tube must be
shortened. This change is irreversible and in any case best
carried out by your WHEELER bicycle dealer, but only after
you have found your preferred position.
Stems come in varying lengths
(a)
as well as different shaft
and binder tube diameters (b). A stem of inappropriate di-
mensions can become a source of danger: Handlebars and
stems can break and thus cause an accident!
If you want your handlebar in a higher position, you may opt
for a riser bar model which has an upward bend. Ask your
WHEELER bicycle dealer for advice.
(e)
Bar ends
give you additional ways of gripping the handlebars. They
are usually fixed in a position that gives the rider a comfortable grip
when pedalling out of the saddle, i.e. almost parallel to the ground or
tilted slightly upwards (by about 25°).
Release the bolts, which are usually located on the underside of the bar
ends (f), by one to two complete turns. Turn the bar ends to the desired
position making sure the angle is the same on both sides (g). Retighten
the bolts to the required torque. Check whether the bar ends are firmly
fixed by trying to twist them out of position.
G
note that the bolted connections of the stem, handlebars,
bar ends and brakes have to be tightened to their speci-
fied torques. Use a torque wrench and never exceed the
maximum torque values! You can find these in the chapter
"recommended torque Settings for components", on the
components themselves and/or in the instructions from the
parts manufacturers, which you can find on the enclosed
CD.
G
If you intend to mount bar ends to the handlebars, verify
first that the handlebars are suitable and approved for the
mounting of the bar ends. Some handlebars must be fitted
with special, reinforcing handlebar plugs. If you are in doubt
or if you have any questions, then contact your WHEELER
bicycle dealer.
G
never fix the bar ends in a vertical position or with their
ends pointing rearwards as this would increase the risk of
injury in the event of an accident.
G
Be aware that the distance you need to stop your bicycle
increases if you are riding with your hands on the bar ends
or on multi position handlebars (h). The brake levers are not
always within easy reach.
