Shimano quality, great price
What can I say? The Deore components by Shimano work great and don't break the bank. Make sure you have all the compatibility questions answered, and order with confidence.

It's a derailleur, nothing more- nothing less
Works great as I have replaced a broken RD with this one.

Great if it arrives 🤪
The derailleur works perfectly, right out of the box, so easy to install and set up. Mine is currently driving an 11s MTB cassette using 12s shifter 🤣 I've ordered 5x, received ONE, two lost in transit?! 🙄🤔🤪

SGS Long cage
Handles the large rear cogs with ease. At a reasonable price point.

Hits every gear
On the bigger jumps between gears, it's a little louder than I would like it to be but if I have to stand up while riding and I shift while I'm standing it doesn't jerk me around or make me have a foot slip so I would say it's a pretty good value for the buy

Quick Shipping, product as expected, works great
I broke my original deore derailleur on a ride when a stick got caught in the chain right at the derailleur. Ordered this replacement on a Saturday and had it on Monday. Quickly installed by a local bike tech and feels crispy and great. Replaced chain while we were at it and bike feels brand new. Very happy.

Reliable
I bought this for a 1x conversion on a non boost mTB. It was easy to setup/adjust, and keeps working so far with nice shifting combined with an xt 11 speed shifter.

Arrivato con gabbia schiacciata perché non aveva un imballaggio, ma solo un sacchetto.
