The Rohloff SPEEDHUB 500/14 has been developed for both pros and performance oriented hobby cyclists who can appreciate it because of its reliability, perfect single gear ratios, wide range of gears, low maintenance and easy operation; its weight and efficiency are ideal even for pro racing. The sealed gearbox ensures reliability and durability even under the toughest conditions. The even increments of 13.6% between gears make it possible to ride continuously at peak performance. The overall range makes sure that you always have access to the right gear regardless of situation. Pure fun is guaranteed. The SPEEDHUB 500/14 is operated by a twist shifter which shifts simply by pulling separate cables up or down. The indexing of the shifting lies not in the shifter as with common designs, but inside the hub. There is no wear on the indexing system nor need to adjust it.
