A system designed for bicycles, typically consisting of a toothed belt, compatible sprockets (for both the crank and rear wheel), and necessary hardware for installation, replaces the traditional chain and derailleur system. This configuration provides a cleaner, quieter, and potentially more efficient method of power transmission.
This technology offers several advantages. Lower maintenance requirements, increased durability, and smoother operation contribute to a more enjoyable cycling experience. The absence of lubrication reduces the likelihood of attracting dirt and grime, resulting in a cleaner drivetrain. While belt drives have existed for decades in industrial applications, their adoption in cycling has steadily grown due to advancements in materials science and manufacturing techniques, making them a viable and increasingly popular alternative to chain-driven systems.
