The Alivio derailleur 9 speed works great

Works great

Seems to work well, also seems to be of better quality than the original one .

I run this on my Fuji mountain bike in good and bad weather. On and off road. I use ALL my gears because I keep my cadence up during steep climbs and single track ups and downs. This rear derailleur does fine by me. My quick and multiple gear changes are good even under stressed conditions such as twisty uphill changes. I do not race but I do abuse my bikes for maximum fun. If you must replace your rear derailleur, be sure you haven't bent the rear dropout.

Perfect replacement for the Bakcau Mule i had 1800 miles on my bike Was going through some mud while I was Turkey, hunting and coming out. I guess the derailer didn't like all the debris that was coming up into it. And it just ripped it off the bike. Anyway, order this replacement, it was a perfect fit. And now I'm back up and running again Remember, if you run any e bike a derailer hanger is a must have. Because it acts as a sheer pin and it won't damage your frame with this type of catastrophic failure. I'm satisfied with the transaction and the seller and the price.It was well worth it

This was an inexpensive Shimano Alvio class derailure system that I bought for my old Rans Nimbus long wheelbase recumbent. The freewheel is a Shimano 7 speed mega and I also changed out the shifter from a Revoshift to a Shimano trigger shifter. What surprised me was how close the derailure rides next to the wheel spokes. It never touched but I had to tie the cable tail back so I wouldn't touch the spokes. It shifts very well especially after changing out the old chain to a KMC 8 speed.

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.

Derailed sent was in good condition. Able to replace Shimano 105 short cage on old Giant Defy to accommodate larger cassette. Seems to work very well
