ACHTUNG : The shortening and slotting of the A-Head fork shaft
as well as the installation of the Speedlifter system must be carried
out professionally. In case of incorrect execution, there is a risk of accident!
Handlebar and stem must be compatible with each other and in good mount-
ing 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 responsible 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 1/4" outer diameter
31.8 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
27.4 mm and 28.6 mm. In addition, the
upper end of the fork shaft must pro-
trude at least 46 mm above the head-
set 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,
only 1 1/8" A-Head stems (option: angle
- adjustable) may be installed. It must
be possible to clamp the 1 1/8" A-head
stem at the rear in riding direction.
An exception is the Speedlifter Twist
Pro SDS which has an integrated
angle-adjustable stem.
