Rohloff Disc Speedhub 500/14 CC QR DB 14-Speed Internal Gear Hub with 4-Bolt Disc Brake Fit

The Rohloff Disc Speedhub 500/14 CC QR DB is a cutting-edge 14-speed internal gear hub designed for riders seeking unparalleled reliability and performance. Featuring a hollow quick release axle spaced at 135mm, this hub integrates a comprehensive boxed kit that includes cables, a torque arm, shifter, and chain tensioner, ensuring seamless installation and operation. Its special 4-bolt disc fitting adds versatility and compatibility with modern disc brake systems, making it an excellent choice for a wide range of cycling disciplines.

Boasting a remarkable 526% gear range, the Rohloff hub offers the equivalent of a 27-speed MTB derailleur setup but with 14 distinct gears that eliminate overlap and wasted effort. The evenly spaced 13.6% gear increments provide smooth and predictable shifts without sudden jumps, while the ability to shift under load or while stationary gives you superior control in any terrain. This precision German-engineered hub is super-efficient thanks to its sealed oil bath mechanism, delivering 95-99% efficiency and requiring virtually no maintenance over thousands of miles.

Built to perform in the harshest conditions worldwide, the Rohloff Disc Speedhub is lightweight at approximately 1.7kg but replaces multiple conventional gear components, reducing complexity and enhancing durability. Included with the hub is a 16t sprocket, and the model features a quick release axle suitable for cross-country use. Rohloff also offers a variety of axle and hub specifications to suit different frame standards and riding styles, including threaded spindles, external gear mechanisms, and post mount options for direct brake caliper attachment.
