Weight comparison
Comparison of mechanical efficiency
The
is with a weight of 120g per gear, the lightest gear hub on the market. The gear range
is the same as high quality 27 gear derailleur systems due to the 14 gears within the hub being evenly spaced out at
13.6% increases. With the

there is no longer a need for the following parts:
-Front and rear derailleur
-Two shifters including
-Rear hub with cassette
-Small and middle chainrings
-The total average weight of all these components is approx. 1600g.
The weight of a fitted
CC OEM including twist shifter, shifter cables and cable guide is
approx. 1820g.
The comparison between the
and the derailleur system shows only a slight increase in
weight. For that, the user receives a:
- Service-free,
- dirt-free full-encapsulated,
- user-friendly gear system and
- high reliability
- alongwith a long life span.
The mechanical efficiency* and consequently the size of the loss of the
is entirely
comparable with that of the derailleur system.
The losses of a derailleur system consist of the friction caused by the bottom bracket, chain, cassette and the hub
bearings. The amount of friction loss depends on the size of the sprockets, the angle of the chain line and condition of
wear. In reality this proves to be 1 - 5%, leaving the derailleur system with a working efficiency lying between 95%
and 99%.
The losses of the
are caused by the fricion coming from the bottom bracket, chain and
gearbox. Here, however, the chain runs in a straight line from just one chainring reducing sideways friction on the
sprockets. Most of the friction occurs when all the planetary gear sets are used within the gearbox. The overall
average loss of the gears within the
is approximately 1 - 5%, leaving the working
efficiency between 95% and 99%.
The
is, therefore, consequently an optimum choice for the everyday and sports rider.
