Adjusting the leg length
When moving the bottom bracket tube your
dealer has to adjust the chain length. By default
the Street Machien Gte comes with a very
long chain so that the adjustment range of the
bicycle can be fully used without the need to
lengthen the chain.
After the first adjustment of the leg length that
you have done together with your dealer while
handing over the bicycle, the chain has to be
shortened so that the arm of the derailleur is
not fully turned forward while shifting on the
big chain ring in front and the big sprocket be-
hind.The derailleur must still be able to com-
pensate a length change of the chain of at least
4 cm (1 1/2"). In order to choose the right
chain length, please consult the manual of the
derailleur manufacturer.
After you have adjusted the front boom you
should seal the gap in the clamping slot be-
tween the front boom and the main frame
with wax or silicone in order to protect your
frame from the penetration of water and dirt
and hence damage through corrosion which
may lead to a broken frame.
We recommend to slightly readjust the front
boom every 3 months so that knees, muscles
and ankles will be used differently, and you
might find a more comfortable and more effi-
cient riding position.
A wrong adjustment may lead to pain in your
knees and inefficient pedalling. In addition we
recommend to ride with a high pedalling ca-
dence, which means to pedal fast and with lit-
tle pressure. Pedalling with too much pressure
may also lead to pain in the knees.You will find
more information about this on page 26.
Check that there is at least a 5 cm (2") clearance between the
end of the chain tube and other parts of the drive train.
Caution!
Take care that the chain tubes
have at least a clearance of 5 cm (2") to the
rear derailleur and the front changer even
under maximum tension of the chain and
that the tubes stay tight in their fastenings.
The front upper tube can be mooved to the
rear for length adjustement. Shorten the
tubes if necessary. If the end of the chain
tube gets into the rotating drive train it
could be locked-up and destroyed.The end
of the chain tubes have to be tightly secured
with a rubber tube over the retention
spring.
Danger!
After the chain has been short-
ened it has to be closed with a special clos-
ing link or a chain riveting tool that expands
the rivet while riveting (i.e. R
OHLOFF
-
Revolver).A poorly joined chain may break
and thus lead to a fall. Have adjustments of
the chain length or the changing of the chain
be done by your bicycle mechanic.
