Alivio RD-T4000 SGS 9-Speed Rear Derailleur - Long Cage

Shimano's Alivio Rear Derailleur is designed to handle the tough conditions of off-road cycling. It has a lightweight aluminum body and low-friction pivots, enabling incredibly easy and seamless gear shifting. The Alivio also comes with 11-tooth pulleys. These pulleys alternate chain-link contact, which not only reduces wear but also makes pedaling smoother, enhancing your overall riding experience.

Using your Shimano Alivio Rear Derailleur is easy. Just shift your gears as you normally would while riding. When you're out on the off - road, be careful not to hit the derailleur against rocks or other hard objects as this can damage it. For maintenance, clean the derailleur regularly with a soft cloth to remove dirt and grime. You can also use a light lubricant on the pivots every few rides to keep the shifting smooth. If you notice any unusual noises or difficulty in shifting, it might be time to take it to a professional bike mechanic for a check - up.
