What are the main differences between hub gear and derailleur systems for bicycles?
Hub gear systems and derailleur systems are two main types of gear systems used in bicycles. The main difference between them is in how they operate.
Hub gear systems are enclosed within the hub of the rear wheel, providing a cleaner and more weather-resistant setup. They typically have fewer gears but require less maintenance and are easier to use, making them ideal for city commuting or casual riding.
Derailleur systems, on the other hand, have gears that are located on the outside of the bike frame and move the chain between different sized sprockets to change gears. They offer a wider range of gear options and are commonly used in road and mountain bikes for their efficiency and ability to handle varying terrains.
In summary, hub gear systems are simpler, more durable, and low-maintenance, while derailleur systems offer a wider range of gears and are more commonly used in performance-oriented cycling.
