Excellent replacement for scrapped gear set
Used these to replace the smashed ones when I fell off my bike. Took my time setting them up and used a new cable /chain and gear change is silky smooth.

Works well
The Shimano Alivio RD-M3100 Rear Derailleur is an excellent choice for anyone looking to upgrade their 9-speed mountain bike's drivetrain. Featuring a sleek, low-profile design and Shadow RD technology, this derailleur provides smooth, reliable shifting while minimizing chain slap and damage from rocks. The 45-tooth total capacity and 36-tooth maximum low sprocket size make it compatible with a wide range of cassettes, while the adjustment barrel allows for easy tuning to achieve optimal shifting performance. Overall, I'm very impressed with the performance and durability of the Shimano Alivio RD-M3100 Rear Derailleur, and I would highly recommend it to anyone looking for a high-quality, reliable rear derailleur for their 9-speed mountain bike.

This was a true Shimano Derailleur, I have order some before and they were packed in Shimano packaging and were off brand. It worked for my son’s bike. Price and performance are good for a kids bike that will end up taking a beating. Easy to install with some basic tools. Once dialed in it shifts like it should.

Produto chegou no prazo, bem embalado, não veio a nota e nem no saite não mostrava porém recebi depois pelo vendedor câmbio original, só falta tirar um tempo e fazer a estação e volto para dar minha opinião.
