naafhankelijk

Naafhankelijk refers to a concept within cycling where the rear hub of a bicycle is a critical component that dictates or influences the functionality and design of the rest of the drivetrain. In a naafhankelijk system, the hub is not merely a passive connector for the wheel but houses intricate mechanisms that manage gear changes, braking, or even provide power.

This dependence on the rear hub is most commonly seen in internally geared hubs (IGHs). These systems integrate a set of planetary gears within the hub shell, allowing for multiple gear ratios without external derailleurs or sprockets. The rider selects gears via a shifter that actuates a cable connected to the hub. This design offers several advantages, including cleaner aesthetics, reduced maintenance, and protection of the gearing mechanism from the elements.

Another form of naafhankelijk is found in certain braking systems, such as coaster brakes or some types of electronic shifting systems that are directly integrated into the hub. In these cases, the hub's internal design is paramount to the bike's stopping power or the electronic control of the drivetrain. The term highlights the intrinsic link between the hub's capabilities and the overall performance and user experience of the bicycle. Understanding naafhankelijk is key to appreciating the engineering and design choices made in various bicycle configurations.
