Never work on Derailleur but the bike didn't have the guard so it bent after few falls. Google YouTube and these "expert" want you to cut the chain so I was prepare to do so but boy I was wrong. There were like couple screws holding the 2 flywheels - I flip 100 of tractors so I knew right off the back there is no way that you need to cut the chain to replace this Derailleur!Take lots of picture on the chain connection or rotation direction before perform the changetake both screw out and the external bracket came off and put the chain back in and tie it down. You don't have to tie it all way down at first, once you get it going & mount it then you will have lots of space to work on.Adjusting the Derailleur is pain in the butt, high limit, low limit but couldn't get the tension right for shift for now. At least my son can ride it.

Bought this to replace a derailleur on a mongoose banish. Its pretty easy to install, just a bolt to mount to the hangar. Instead of breaking the chain to thread it, i just popped one screw off the cage. Worked just fine. Its not of the higest qualoty, but for a realtively cheap bike and cheap part, it shufts the gears just fine. Indexing it is easy too. The h and l screws turn easy and are easily accessible. All in all, im happy with it. The test is to see how long it will last when a kid abuses it daily.

For the price this derailleur works very well. Installation and adjustment were easy and straight forward. Shifts smoothly and accurately. Quite satisfied.

I was a little concerned; as I had never replaced or installed this particular part on any bike before. To my pleasant surprise; the part came with easy to read/understand instructions. It was an easy/painless install & the part works great!

Shifting doesn't work but imma make it work. I knew nothing about this starting out and thanks to YouTube I now know I know even less than I thought I did. Installed it without a video, messed it up, installed with a video, messed it up, asked chat got what in doggos name I should do and it said thread the shifter line through the little cylinder hole on the left (upside down bike right) of the logo (derailleur casing) and then tighten in the bolt with its little space for the line. Finally got it right because I miss aligned the chain. I need to watch an adjusting video for this to get the shifting right and once I do that it should be good. I have bent the derailleur 6 times trying to get it to work, not a problem for my pliers. I can't wait to grease everything up and have it running smoothly for the preperation to evolve into an E-bike. Ill be upgrading the derailleur before that because I know this cheap one is just a temporary fix, it's doing it's job to get me from home to work and back.

Easy to install

After 2 months, part blew apart into a few pieces while riding.
