Adjusting the above seat steering
handlebars
Your GrassHopper with above seat steering is
equipped with a height adjustable and foldable
stem. It comes with the Glideflex folding pivot
from T
ERRACYCLE
.
Alignment of the stem to the front wheel
Check the parallel alignment of the stem to
the front wheel by folding it completely for-
ward and looking at both stem and front
wheel.To adjust this alignment, loosen both
clamping screws of the stem / fork steerer
tube connection. Do not loosen the screw in
the headset cap. Sit on the bike, hold the front
wheel with your feet and turn the stem so
that it is aligned to the front wheel.
Then tighten both clamping screws alternately
with 8–10 Nm. Check the clamping by trying
to turn the stem against the front wheel.
Check the play of the head set bearing, see
page 50.
Adjusting the handlebars
Height adjustment of the handlebars
The stem is height adjustable by telescopically
sliding the stem extension on the lower part.
Loosen the clamping screw of the clamp at the
lower end of stem extension. Move the stem
extension to the desired position.Align the
stem extension parallel to the front wheel, so
that the handlebars are perpendicular to the
front wheel.Tighten the clamping screw with
4–6 Nm.
Angle adjustment of the folding stem
The Glideflex unit is equipped with a backstop
adjustment screw close to the pivot axle.To
adjust the backstop, fold the stem forward and
turn the backstop screw in or out with a 4
mm allen wrench.Turning the bolt in (clock-
wise) allows the handlebars to fold further
back; turning the bolt out stops the handlebars
from going as far back.
Adjusting the folding friction
To adjust the folding friction, tighten or loosen
the pivot bolt with a 5 mm allen wrench.
Tightening the bolt will increase friction; loos-
ening will decrease friction.
Danger!
Aligning the stem can require ad-
justment of the head set bearings. In case of
assembly errors the danger of accidents is
increased. If you are in doubt have your bicy-
cle mechanic adjust the stem.
Danger!
The hex-headed screw in the cap
adjusts the play of the steering head bearing.
This screw does not help to clamp the stem
tightly to the steerer tube. It does not se-
cure it against turning.Take care that both
clamping screws on the side are tightened as
prescribed after you have finished your
works at the stem. Otherwise the stem may
turn while riding and cause an accident.
Danger!
The stem extension must not be
positioned higher than the „max“ mark on
the lower stem part. In no case may the end
of the lower stem half become visible in the
slot of the stem extension.The clamp must
be positioned tightly to the lower end of the
stem extension.The clamping slot of the
clamp must be aligned to the slot in the
stem extension.
Caution!
Do not turn the screw so far out
that it contacts the top of the stem when it
is folded back.The bolt must contact the
sloping surface.
