Operation Manual
The range within which the front derailleur keeps the chain on the chain-
ring without itself touching the chain is very small. This adjustment is a job
best left to your bicycle dealer.
It is often better to let the chain drag slightly on the derailleur than to risk
having the chain fall off the chainring, which would interrupt the power train.
The front derailleur, just like the rear derailleur, has limit screws marked “H”
and “L” that reduce the movement range .
As with the rear derailleur, the cable of the front derailleur is subject to
lengthening and hence to reduced precision in gear changing.
If necessary, shift to the small chainring and increase the tension of the
Bowden cable by turning the adjusting bolt through which it passes at the
entry to the gear shifter or at the frame under the down tube .
Always check after an accident whether the guide plates of the
front derailleur are still parallel to the chainrings!

Adjusting the front derailleur is a very delicate job. Improper
adjustment can cause the chain to jump off, thus interrupting
the power train. This can cause an accident!
Be sure to go on a test ride in a place free of traffic, after adjust-
ing the gears of your bicycle.
Two advantages of multi-speed hubs are their enclosed design and the
fact that you can switch through all gears by the same lever. Besides this,
the chain lasts a lot longer than with derailleur gears, provided it is serviced
regularly.
Multi-speed or internal gear hubs from are available with a free-
wheel, i.e. the free-wheel hub is combined with a hand activated V- or roller
brake, or with an integrated drum brake, also referred to as back-pedal
brake. The latter is operated by pedalling backward. The best braking power
is achieved with the pedals on a horizontal level.

is achieved with the pedals on a horizontal level and in low gears.

combined with a hand activated rim brake (mechanical or hydraulic), or with
a disc brake (mechanical or hydraulic).
make gear shifting smooth, i.e. you always ride in the ap-
propriate gear. With NuVinci hubs power transmission is ensured by balls.
Internal gear hubs are equipped with a twist grip or thumb shifter for chang-
ing gears as well as with an indicator showing the current gear. According
to the hub manufacturer you can either continue pedalling without load on
the pedals or freewheel. Read the operating instructions of the gear manu-
facturer. If you are in doubt or if you have any questions, please contact
your bicycle dealer! In any case, make sure changing gears makes as little
noise as possible.
twist grip shifters : To change gears, twist the grip, stop pedalling
for a moment and do not move the pedals. also allows gear
shifting during pedalling and in stationary.
Twist grip shifters for and : Continue
pedalling during shifting. However, to ensure a jerk-free and low-noise gear
shifting, be sure to reduce your pedalling power.
