Weight Comparison
The Rohloff SPEEDHUB 500/14 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 Rohloff SPEEDHUB 500/14 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 Rohloff SPEEDHUB 500/14 CC OEM including twist shifter, shifter cables and cable guide is approx. 1820g.
The comparison between the Rohloff SPEEDHUB 500/14 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.
Comparison of Mechanical Efficiency
The mechanical efficiency* and consequently the size of the loss of the Rohloff SPEEDHUB 500/14 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 Rohloff SPEEDHUB 500/14 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 Rohloff SPEEDHUB 500/14 is approximately 1 - 5%, leaving the working efficiency between 95% and 99%.
The Rohloff SPEEDHUB 500/14 is, therefore, consequently an optimum choice for the everyday and sports rider.
