Inkesky RD-TZ31-GS 6/7 Speed Rear Derailleur with Direct Mount, Medium Cage, for Mountain Bike

no issues, shifts well, easy to install if you have some bike mechanic skills. has not failed yet. I thinks great for average bike uses.

It was pretty quick and easy to install this. The longest part for me was just disassembling my old chain which was rust, and replace too, to get this installed. When you install a new derailleur you need to take apart your chain. I'd recommend you take a picture of the chain going through the derailleur so you know the direction to thread it through when you reassemble it. It isn't necessarily that confusing, but if you haven't done it before, it helps to have the picture. Otherwise installing and easily adjusting the high and low limits is easy. I did this on my daily commute bike which gets a lot of abuse and left out in the elements, so the the cost to functionality ratio on this is perfect, it easily shifts gears and works well.

Working just fine. I would have prefered more detailed installation instructions, but the product itself is of good quality at a great price.

This was an exact replacement for one that got damaged. I don’t know much about bicycles or derailers. This was a typical Walmart, multi speed bike, and this derailer worked perfect.

Replaced a broken derailleur on a low-end mountain bike. Installation and adjustment were easy. Works well.

Received it bent and a broken sprocket I had a spare or else I would have to return it

Good

It’s been sitting on my shelf waiting to be installed for a month so there’s no in returning it but at least I can warn others amI just opened it to find out the whole thing is unusable the whole thing is mangled it looks I received someone’s return order and no one checked the box very not happy beware before you buy poor quality and poor quality control.
