Threadless Headset - Aheadset - Scott TIME TRIAL MACHINE 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.
SAFETY INSTRUCTIONS
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®.
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.
Check the headset for play as described above (d). Do not overtighten the
headset. Risk of headset failure!
