Great for any flavor of MTB!
This RD is not just for DH. I use it on my 1x10 hard tail, race-oriented 29er and it has performed flawlessly. I previously used an XTR and wanted to get something more robust and durable than XTR. There is a slight weight penalty when compared to XT/XTR, but it's still lightweight for what you get...beefy links, strong spring, very accurate shifting. The clutch works great, but even with it turned off I have not had a dropped chain. I paired this with the matching Saint shifter and my XTR brake lever (i-spec A) and it's been perfect for my XC/Trail riding style.

PROS: Lightweight, Attractive Design, Durable, Easy To Install

CONS: Limited To 36t Cog

BEST USES: Mountain Biking, Trail riding, XC

Smooth performer
The engineers at Shimano did their research and put out a great product. I an happy with the whole group set. This derailleur is just stout out of the box, strong spring, paired with the Saint shifter and it is an unbeatable set. I was amazed how easily and smooth this shifted. The powerful spring basically forces the chain into the correct gear, engagement is instant and smooth. I did not use the clutch feature which is suppose to eliminate noise and chain slap.

Give SRAM the can
After snapping an X9 on my park bike, I decided to go 1x10. Couple more bucks for the Saint but I think it's worth it over the Zee. Clutch works awesome and super smooth once it's set up.

Soooo...
Love this shifter BUT... had first M820 shifter start skipping shifts while up-shifting here and there. Sent it back to Shimano and POW!!! new shifter. Very short down time. Took a week from the time I mailed mine in until I had a brand new juan to install. Not too shabby. Haven't had the issue with the second juan.

Will this work with a 2 x 10 setup?
zach h on Feb 14, 2017
BEST ANSWER: Yes it will but due to the short cage your chain length can be an issue depending on your rear triangle. I run it on a 2015 SC Bronson carbon and it BARELY has enough room.
I believe that this has a built in mode converter to work fine for my biggest sprocket 36t?
A shopper on May 27, 2017
BEST ANSWER: Yes, but you have to install the mode converter (grab the Shimano Dealer Manual for rear derailleurs for instructions)
