ATTENTION :
as the installation of the Speedlifter system must be carried out profession-
ally. In case of incorrect execution, there is a risk of accident! Handlebar and stem
must be compatible with each other and in good mounting condition. The brake and
shift cables as well as electrical cable connections to the handlebar must be long
enough to make sure that they are free of bends at the highest possible handlebar
position and that they do not obstruct the steering in any way. If necessary, the
cables must be re-routed." The person who installs the Speedlifter system is respon-
sible for all risks of damage in the event of an incorrect installation. We therefore
strongly recommend installation by a qualified bicycle dealer.

3. INSTALLATION REQUIREMENTS

(Excerpt from the mounting instructions)
To install the Speedlifter, the bike must
have a threadless A-head fork with
metal shaft and 1 1/8" outer diameter
28.6 mm.
The Speedlifter quill diameter must be
compatible with the inner diameter of
the fork shaft. The Speedlifter system
quills are currently available for metal
fork shafts with an inner diameter of
24.4 / 24.5 / 24.6 mm and 25.4 mm. In
addition, the upper end of the fork shaft
must protrude at least 46 mm above
the headset for the installation of the
Speedlifter with the fork mounted.
The fork shaft end protruding above
the A-Head headset bearing must
have a vertical slot at the rear as seen
in the riding direction. This approx. 4
mm wide and a total of 24.5 mm long
vertical slot ends in a Ø 6 mm hole.
In combination with the Speedlifter quill,
1 1/8" A-Head stems (option: angle-ad-
justable) may only be installed together
with the supplied, slotted Speedlifter
A-Head reducing sleeve .
An exception is the Speedlifter Twist
Pro SDS which has an integrated an-
gle-adjustable stem.

direction)! The stem length must not be
more than 135 mm."

sleeve must have at least the same
available clamping height as that of the
stem.
After adjusting the headset, a maxi-
