Speedhub

Speedhub refers to a specific type of internally geared bicycle hub developed by Rohloff AG. It is renowned for its exceptionally wide gear range and durability, making it a popular choice for touring, commuting, and off-road cycling. The Speedhub consists of a planetary gear system housed within a single rear bicycle hub. This system allows for 14 distinct gears, which are internally selectable. The gear ratios are evenly spaced, offering a range comparable to a traditional 27-speed derailleur system.

One of the primary advantages of the Speedhub is its sealed design. This protects the internal components from dirt, water, and other contaminants, leading to significantly reduced maintenance requirements compared to external derailleur systems. It also allows for the use of a single chainring at the front, simplifying drivetrain maintenance and reducing the risk of chain drops. The Speedhub is known for its robust construction and has a reputation for longevity, often outlasting multiple bicycle frames. Installation and servicing, however, can be more complex than with conventional hubs, often requiring specialized tools and knowledge. Despite its higher initial cost, the long-term benefits of reduced maintenance and increased reliability make it a compelling option for many cyclists.
