Stems For Threadless Systems - Aheadset - Scott TIME TRIAL MACHINE Owner's Manual

Stems for threadless systems – Aheadset®
In the case of SCOTT bikes with Aheadset® headsets the stem also serves to
adjust the bearing preload. If you change the position of the stem, you have to
readjust the bearing play (see the chapter "The headset on the SCOTT bike" and
the manuals of the component manufacturers).
The vertical setting range is determined by the intermediate rings, also referred
to as spacers (b). In the case of flip-flop stem models the stem can be mounted
the other way round (c) to achieve a different handlebar height.
For modifications unscrew the bolt at the top of the fork steerer tube which
serves to adjust the initial bearing pressure, remove the Ahead cap and release
the bolts on either side of the stem by up to three turns (d). Remove stem and
spacers 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. You can determine the
handlebar height by the arrangement of stem and spacers. Slip the remaining
spacers onto the fork steerer tube above the stem. Adjust the headset, as de-
scribed in the chapter "The headset on the SCOTT bike".
If you want to turn the stem around, you have to also release the bolts of the
faceplate securing the handlebars (e). If the stem is fitted with a cap, you can
simply take out the handlebars at this point. If it is not fitted with a cap, you have
to remove the handlebar fittings.
Mount the handlebars and, if necessary, the handlebar fittings, as described in
the chapter "Adjustment of handlebar tilt and brake lever/shifter units on SCOTT
road bikes and SCOTT cyclo-cross bikes" and/or in the manuals of the compo-
nent manufacturers.
Check after the adjustment or assembly, whether the handlebars are firmly seat-
ed in the stem by trying to rotate the handlebars downwards (f). Verify whether
the handlebar/stem-combination can be turned relative to the fork. Do this by
taking the front wheel between your knees and trying to twist the handlebars.
If there is movement, carefully tighten the bolts a little more by using the torque
wrench, observe the maximum torque value and check again the proper fit.
Tighten carefully by approaching the prescribed maximum torque value in small
steps (0.5 Nm increments) and check in between the proper fit of the component.
Never exceed the maximum torque value indicated by Scott! Ask your SCOTT
dealer to explain you both function and adjustment of your stem or, still better,
let him do that work.
