• Release the bolt at the top of the fork steerer tube which serves to adjust the
initial bearing pressure and remove the Ahead cap.
• Loosen the bolts on the side of the stem by two to three turns.
• Remove the stem from the fork steerer tube. In doing so keep hold of both
frame and fork to prevent the fork from slipping off the head tube.
• Now you can remove the spacers.
• Remount the stem entirely on the fork steerer tube and slip the spacers you
have removed above the stem.
• In case you want to turn the stem around: To do so release the bolts of the
stem face plate clamping the handlebar and remove them carefully. Refasten
the handlebar after you have turned the stem.
• Centre the handlebar accurately in the stem clamp, i.e. the drops should be
in parallel to the ground or point with the ends slightly downwards. Tighten
all bolts of the stem clamp with a torque wrench according to the indications.
• Readjust the headset and retighten the stem to the recommended torque value
after you have aligned it (see also the chapter
“The Headset”
).
Danger:
Stems come in very different lengths and shaft and binder tube diameters.
A stem of inappropriate dimensions can become a serious source of dan-
ger: Handlebars and stems can break and thus cause an accident. Make
sure that the stem clamp (the handlebar clamping) and the steerer tube
clamping are free of sharp edges. Your STEVENS dealer will be pleased to
help you.
Caution:
With full carbon forks keep in mind that sufficient clamping forces are
usually already reached well below the maximum torque values indicated
by the stem manufacturer!
Danger:
Be sure to tighten the
bolted connections
of the stem and the
handlebar properly.
Otherwise the handlebar
or stem may come loose
or break. You find the
prescribed values on the
components themselves
and/or in the chapter
“Recommended Torque
Settings”
.
Check whether the handlebar is firmly seated in the stem by trying to rotate the
handlebar downwards. Also check whether the handlebar/stem unit can be turned
relative to the fork. Do this by taking the front wheel between your knees and trying
to twist the handlebar. If the parts can still be moved, the bolts must be carefully
tightened once again and the tight fit must be checked once again. Do not exceed
the maximum torque values.
STEVENS recommend that you always use handlebar and stem of the same
quality from the same manufacturer.
Integrated Cable Routing
Some models have integrated cables. This means that there is an internal
routing of brake hoses, Bowden cables in the handlebar-stem-combination, in the
frame and possibly also in the fork.
Adjustment work requires specialist knowledge, experience, suitable tools and
manual skills and should therefore only be carried out by professionals. Contact
your STEVENS dealer.
Nevertheless, if you want to do it yourself, make sure that the hoses remain
free of too high tensile forces when you adjust the handlebar-stem-combination,
e.g. when adjusting the handlebar height and aligning the handlebar. Therefore,
proceed with caution when doing this work.
