Changing gears
All 14 gears of the
are selectable through one twist shifter, so that
in one turn it is possible to change up or down by one or more gears.
The mark on the twist shifter casing next to the gear numbers informs the user of which gear
has been selected. The assembly instructions show the twist shifter being fitted to the right
hand side of the handlebars, however, in special circumstances it is possible to fit the twist
shifter to the left hand side. When rotating the twist shifter in the direction of #14, a harder,
faster gear is selected. When rotating the twist shifter in the direction of #1, an easier, slower
gear is selected.
In contrast to other gear systems on the market, with the
there is
no delay between gear selection on the twist shifter and gear change in the hub. The moment
the notch can be felt in the twist shifter, the gear has been changed. Therefore a quick and
failure free gear change is possible whilst riding and also when stationary.

with pressure on the pedals is not
necessary when being used appropriately. However due to the robust construction of the
changing gear under pressure is possible and is not harmful to
the hub. It is however possible that when changing gears under high pressure the hub could
accidentally fall into a neutral gear, this is due to the coupling elements not seating correctly
into the next elements and therefore rebounding back. If this occurs the rider could lose
balance and crash. Changing gears under high pressure is at the riders own risk.
If changing up and down slowly or under high pressure between the gears #7 and #8, it is
possible to fall momentarily into gear #11 or #14.

When changing, gear coupling elements inside the hub must move and when there is more
pressure on the pedals it is obvious there is more pressure on these coupling elements resulting
in a harder gear change. W
stationary or when there is less pressure on the pedals, the twist
shifter has less resistance and therefore a lighter gear change is possible. In a situation
whereby it is not possible to reduce the pressure on the pedals (e.g. hill climbing), it is still
possible to change gear quickly and smoothly. Simply change gear when the cranks are in a
straight up-down position where hardly any pressure is being applied upon the pedals.

Wearable parts
When riding in particular gears, one of two different types of riding noise could be heard.
Construction characteristics prove that in most gears a free-spinning noise can be heard which
is particularly noticable in gears #5, #6 and #7. When riding with a higher pressure upon the
pedals, a higher frequency can be heard through the gears #1 to #7 which is typical for
straight-toothed precision gears. Through different frame types these noises can be of
different volumes in regard to noise transfer (the tubes of the frames react as a resonator for the
sound waves). Different noises are noticable whilst freewheeling depending on which gear
you have currently selected. This is due to different parts of the gear mechanism rotating
within the hub.
All the gears and coupling elements of the
are built from
specially hardened steel and are precision finished. In the first 1000km use, the
loses microscopic particles from all functioning components as part of
the hubs last fine filing. After this process is completed the riding noises quieten and the
changing of gears becomes easier. During this process it is not necessary to take extra special
care.
Should the bike be pushed, it is possible that the cranks could also start to turn. This occurs due
to the hub seal automatically activating the sprocket. Bad seals and a very light running
bottom bracket make it easier for the cranks to turn. A drop of
lubricant change
assistant fluid (Art.No. 8402) through the holes in the sprocket onto the hub seal will reduce
this acivating effect.
The wearable parts are: The sprocket, chainring, jockey wheels on the chain tensioner, shifter
cables and the brake disc. How quick the parts wear is down to how the product is used and
cared for (pressure, dirt, weather and care). To guarantee the safe function, these parts must be
replaced as soon as they are no longer capable of performing correctly. Let the workings of
your bike be regularly checked over by a professional bike workshop.
