Twist grip shifter for : To change gears, twist the grip, stop
pedalling for a moment and do not apply any load to the pedals. You need
not stop to do so. Smooth gear shifting is best with the pedals on a vertical
line, i.e. one above the other.
Practise switching gears in a place free of traffic until you are
familiar with the functioning of the shift levers or twist grips of
your bicycle.
Multi-speed hubs need not be adjusted very often. The adjusting mecha-
nism is mainly located at the hub or at the gear box. There are two (red)
marks which have to be brought into alignment by adjusting the cable di-
rectly at the lever or twist grip (see adjustment of the derailleur gear). Care-
fully read the operating instructions of the gear manufacturer. If you are in
doubt or if you have any questions, please contact your bicycle dealer!
Regularly check the reliable fit of the bolted connection of the
hub and of the torque arm to the frame .
If you have a Rohloff speed hub, be sure to make an oil change
annually or after 5,000 km (3,100 miles). If you are in doubt or
