Gear Range Comparison of the Rohloff Hub
The right gear system plays a very important role in making bike riding fun. The difference between the largest and the smallest gears (range of gears) and the size of the increases between them play a large part in deciding which riding situation the gear system has been taylored to (e.g. High speed racing). The size of the increases between gears will decide how smoothly the flow is from gear to gear. Tuning the range of gears, the number of gears and the increases between each of these gears will eventually define the riding fun. The shifting between gears in all riding situations (including whilst stationary) must then be made as light and intuitive as possible in order to maximise the riding fun.
If the range of gears lies over 500% and the increase between these gears lies under 15% but remains evenly spaced out, then the rider has the ability to change gears at the precise moment when needed, regardless of the current riding conditions and without changing the comfortable crank rotation speed. This is only possible with the high performance hub Rohloff SPEEDHUB 500/14.
The diagram below shows a comparison between a 27-speed derailleur gear system and the Rohloff SPEEDHUB 500/14. There is no difference between the range of gears and the range of effective gears. Next to this is the optimum, evenly increased speeds of the Rohloff SPEEDHUB 500/14. Impossible for the derailleur gear system is the shifting speed and the possibility of shifting through all gears with just one shifter whilst stationary or whilst pedaling. Just like the derailleur system, the range of gears can be taylored to the riders individual wishes whether that be for a faster or a slower riding style.
Speedhub Shifter Cable Routing
The Rohloff Speedhub has two different shifter cable routing options, Internal Cable Routing and External Cable Routing (EX).
The hub comes standard with Internal Cable Routing except for the disc brake (DB) model that comes standard with the External Cable Routing option, this is necessary to provide clearance for the disc brake caliper and rotor.
The External Cable Routing can be ordered as an upgrade for other hubs by simply adding the EX designation to the hub model name. Some applications may not allow the use of Internal Cable Routing because it requires a cantilever brake boss to exist no closer than 240 mm from the rear axle. The EX shifter box can be oriented in 12 different 30º increments about the axle. It may also be flipped in the opposite direction providing a total of 24 different mounting positions to satisfy your cable routing needs. Both cable routings are capable of quick release for easy wheel removal and installation.
