Regularly check the reliable fit of the bolted connection of
the hub and, if necessary, of the torque arm at the frame
(a+b).
Shimano recommends for example regular maintenance (oil
change) every 5,000 km (3100 miles) or every two years.
Follow the operating instructions of the gear manufacturer,
which you can find on the enclosed CD, or else contact your
WHEELER bicycle dealer.
Comply also with the operating instructions of the gear
manufacturer, which you can find on the enclosed CD. If
you are in doubt or if you have any questions, then contact
your WHEELER bicycle dealer.
CoMBInED MULTI-SPEED HUB-DERAILLEUR GEARS
operation and Control
The properties of both gear systems are combined in the so-called
dual drive gears from Sram. Compared to ordinary derailleur gears,
it has the advantage that it can also be shifted when the bicycle is at a
standstill, for example, to make it easier to start off from traffic lights.
And, compared to most multi-speed hubs, there is a far wider range of
gears available, which is especially noticeable when going up steeper
slopes.
In the standard version of the Sram dual drive the two shifters are
in one hand (c). Use your thumb to operate the shifter to select the
desired basic gear of the 3-speed multi-speed hub to match the topog-
raphy. The WHEELER bicycle should roll on for a fraction of a second
without you moving the pedals.
The derailleur gears (optionally with 8 or 9 sprockets) are operated by
the twist grip. Alternatively, there is also the 27-speed version with two
separate thumb-operated shifters. You need to turn the pedals to shift
gear, preferably while applying less force to the pedals.
Braking is always done by hand, because derailleur gears cannot be
combined with a back-pedal brake.

Familiarize yourself with your gears and brakes in a place
free of traffic.

The correct adjustment of the multi-speed hub-derailleur
gears should be left to an experienced bicycle mechanic.
Before you start any adjustment work, you should in all cas-
es read the operating instructions of the gear manufacturer,
which you can find on the enclosed CD.
Checking and Readjusting
The multi-speed hub of the combination is adjusted as described in the
chapter "multi-Speed hubs (internal gear hubs)". The adjustment
of the derailleur gears is described in the chapter "derailleur gears"
under "adjusting the rear derailleur".

the torque arm
