Before the first ride: adjusting your
new GrassHopper
The seating position is essential for your riding
comfort, well-being and efficient cycling on the
GrassHopper.Therefore you should adjust the
frame, seat, handlebar and suspension to your
individual requirements.
In order to adapt the GrassHopper as closely
as possible to your body dimensions and to
find the ideal seating position you need to ad-
just the front boom, seat and handlebars.
If your bike is equipped with the optional front
boom-quickadjust, please read the instructions
in the seperate manual in addition to the fol-
lowing instructions.
Adjusting the leg length: moving the
front boom
In order to adjust the leg length you have to
move the front boom (the front part of the
frame where the cranks are mounted) within
the main frame. Unscrew the screw M8x35 un-
der the main tube with a 6 mm Allen key.Take
a grip on the front changer tube or both
cranks and move the front boom into the
frame or pull it out while cautiously turning it.
When you pull out the front boom shift the
chain on the smallest chain ring and sprocket
and turn the cranks a little bit backwards
while pulling.Thus the chain is not under ten-
sion.
Adjusting the leg length

All procedures described here re-
quire a certain degree of skill, suitable tools
and mechanical aptitude.After any adjust-
ment perform a static check and take a test-
ride on a quiet street, away from traffic. If
you have any doubts please contact your lo-
cal dealer.
Caution!
After you have unscrewed the
clamping screws take them off and examine
them for deformation. Lubricate threads and
heads thoroughly.Then re-fit the screws. If
they don't turn easily you will have to re-
place the screws.
