Provided that it is serviced regularly, the drive chain has a comparatively longer
service life. And this applies even more if it is protected from the influences of
the weather by a sealed chain box.
With multi-speed hubs normally the power transmission and the gear ratio
adjustment is guaranteed via one or several planetary gears, depending on the
number of gears. To change gears the pedal force should be reduced shortly.
In contrast to derailleur gears, multi-speed hubs cannot only be combined
with manually actuated brakes (rim, drum, roller or disc brakes), but also with
back-pedal brakes
(f)
(roller or drum brakes) that are actuated by a reverse
rotation of the pedals. The best braking power is achieved with the pedals on a
horizontal level.
In the case of multi-speed hubs and gearbox shift systems “1” stands for the
first, lowest gear. The gears are shifted through one after the other, if possible
without turning the pedals, at least, however, at reduced pedal pressure. The
highest number stands for the highest gear.
NuVinci N360 gear hubs
are designed to allow stepless shifting by means of a
twist grip within their range of gear ratio. With the NuVinci hub the force trans-
mission is ensured by balls instead of toothed wheels. Make it a rule to shift only
while pedalling at reduced force.
With
NuVinci
the actual gear ratio is indicated to the cyclist on the display. If the
cyclist climbs uphill, the gear ratio is low, on level ground the gear ratio is high.
The
H-Sync
gear system integrates the
NuVinci Harmony®
gear hubs into the
Intuvia system of its Bosch drive. With H-Sync you can predefine your preferred
cadence (between 30 and 80 turns per minute). The drive readjusts automat-
ically – both uphill as well as downhill. This allows you to always maintain your
preset cadence.
For more information see the manuals of the component manufacturers on this
SCOTT info CD.
Adjusting the front derailleur
The range within which the front derailleur keeps the chain on the chainring
without itself touching the chain is very small. If the chain tends to jump off the
chainring, you will need to reduce the movement range in the same way as with
the rear derailleur, i.e. by turning the limit screws marked “H“ and “L“
(a)
. The
limit screws are adjusted by your SCOTT dealer. They do not alter their position
during normal use.
As with the rear derailleur, the cable of the front derailleur
(b)
is subject to
lengthening which leads to a 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
(c)
.
DANGER!
G
Always check after an accident whether the guide plates of the front derail-
leur are still parallel to the chainrings. Make sure they do not touch the large
chainring which would block the drive. Risk of accident!
DANGER!
G
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 a fall!
CAUTION!
A
Do a test ride in a place free of traffic, after adjusting the gears of your
bicycle.
MULTI-SPEED HUBS (INTERNAL GEAR HUBS)
Operation and control
The advantages of multi-speed hubs
(d+e)
are their enclosed design. Unlike de-
railleur gears the gear drive is within the hub body, only the primary ratio from
the chainring to the sprocket being outside. What is more, all the gears can be
shifted through with one gear shifter.
