The Rohloff Speedhub 500/14 32 Hole Internal Gear Quick-Release Disc Rear Hub 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. This hub features a sealed gearbox that ensures reliability and durability even under the toughest conditions. The even increments of 13.6% from gear to gear make it possible to always ride at the performance peak. The overall range makes sure that you have the right gear in every situation. Pure fun is guaranteed. This 14 speed internal gear hub 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.
