Release the clamping bolt(s) located on the side of the stem by one to two com-
plete turns (c). Gently tighten the countersunk adjusting bolt on top a little, e.g.
by a quarter turn (d), by using an Allen key.
Realign the stem to ensure that the handlebars are at right angle to the wheel.
Make sure the front wheel is in line with the top tube and the stem. Tighten the
clamping bolts of the stem. Use a torque wrench and never exceed the max-
imum torque values! You will find the prescribed values in the chapter “Rec-
ommended torque settings for your SCOTT bike”, directly on the components
and/or in the manuals of the component manufacturers on this SCOTT info
CD. Check the headset for play as described above (a). Do not overtighten the
headset. Risk of headset failure.
DANGER!
G
Bear in mind that by overtightening the bolts the stem can crush the steer-
er tube. In particular forks with carbon steerer tubes are highly sensitive to
overtightening the steerer tube clamping at the stem. Risk of breakage! Make
sure the clamping area is absolutely free of grease when any of the clamping
faces is made of carbon. If necessary, use carbon assembly paste in the clamp-
ing areas to ensure maximum clamping.
DANGER!
G
Check the secure seat of the stem by taking the front wheel between your
legs and trying to turn the handlebars and stem relative to the wheel (e). A
loose stem can cause an accident.
DANGER!
G
Never change the preloading mechanism in the inside of the fork steerer
tube. Never install a star nut in carbon fork steerer tubes (f).
CAUTION!
A
Do not overtighten the upper bolt, it only serves to adjust the headset play.
NOTE!
I
If you do not succeed in adjusting the headset, this can have several rea-
sons. If you are not absolutely sure, ask your SCOTT dealer for help.
DANGER!
G
Riding the bicycle with a loose headset increases the stress on fork and
bearings. This can lead to damage to the fork. Risk of falling!
Checking and readjusting
Check the headset for play by placing your fingers around the upper headset
cup (a). Bring your weight to bear on the saddle, pull the front brakes with your
other hand and push the SCOTT bike firmly back and forth with the wheel re-
maining on the ground. If the bearing has play, you will feel the upper head tube
race moving in jerks relative to the lower head tube race - visible as a small gap
in between the head tube races.
To check whether the headset runs smoothly, lift the frame up until the front
wheel no longer touches the ground. The handlebars should turn from far left to
far right without feeling roughness or tightness at any point. With a gentle tap
on the handlebars (b) the fork should turn easily from the middle position.
If you face any problems during the test, contact your SCOTT dealer.
DANGER!
G
Adjusting the headset requires a certain amount of experience and should
therefore be left to your SCOTT dealer.
THREADLESS HEADSET – AHEADSET®
The distinct feature of this system is that the stem does not sit within the fork
steerer tube, but rather slips over the fork steerer tube, which in this case is
threadless. The stem is thus an important part of the headset, as the stem
clamping fixes the adjustment. You generally only need one or two Allen keys
and a torque wrench to adjust an Aheadset®.
