Threadless Headset - Aheadset; Lighting Of Your Scott Bike - Scott Road Owner's Manual

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 the fork should turn easily from the middle position (a).
If you face any problems during the test, contact your SCOTT dealer.
DANGER!
Adjusting the headset requires a certain amount of experience and should
G
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®.
Release the clamping bolt(s) located on the side of the stem by one to two turns
(b). Gently tighten the countersunk adjusting bolt on top a little, e.g. by a quar-
ter turn (c), 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 maxi-
mum torque values! You will find the prescribed values in the chapter "Recom-
mended 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 (d). Do not overtighten the
headset. Risk of headset failure!

DANGER!
Bear in mind that by overtightening the bolts the stem can crush the steer-
G
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!
Check the secure seat of the stem by taking the front wheel between your
G
legs and trying to turn the handlebars and stem relative to the wheel (e). A
loose stem can cause an accident.
DANGER!
Never change the preloading mechanism in the inside of the fork steerer
G
tube. Never install a star nut in carbon fork steerer tubes.
CAUTION!
Do not overtighten the upper bolt, it only serves to adjust the headset play.
A
NOTE!
If you do not succeed in adjusting the headset, this can have several rea-
I
sons. If you are not absolutely sure, ask your SCOTT dealer for help.
