Shimano Rear Derailleur M3100 Alivio 9-Speed

The Shimano Alivio M3100 rear derailleur features a sleek low - profile design. Its adjustable barrel allows you to bike aggressively with minimal interruptions. With 9 speeds, a total capacity of 45T, a top sprocket range from 11T to 12T, and a low sprocket range from 32T to 36T (max difference 22T), and 11T pulley teeth, it offers a smooth and efficient riding experience.

Using your Shimano Alivio M3100 rear derailleur is easy. Just shift your gears as you normally would while riding. Make sure to adjust the barrel to get the best performance. When it comes to maintenance, keep it clean by wiping it down after each ride, especially if you've been in dirty or wet conditions. Avoid using high - pressure water as it can force dirt into the moving parts. Periodically, lubricate the moving parts with a good quality bike lubricant. If you notice any unusual noises or difficulty in shifting, check the adjustment of the barrel and the chain for wear. Also, don't over - stress the derailleur by shifting under heavy load.
