Pros

  • 36t Cassette Capable
  • Best Choice For 8 Or 9sp
  • Better Cable Routing
  • Better Chain Tension
  • Easy Install
  • Low Side Profile

Cons

    Best Uses

    • 36 Tooth Cassette Capable
    • Mountain Biking

    Comments about Shimano Deore M592 SGS Shadow Derailleur:

    This is the best choice for 8 or 9 speed because it can handle 36 tooth rear cassette . The "Shadow Design" means it has a low side profile so it's tucked under chain stay and out of harms way. I bought this to replace an older designed
    XT that could not handle cassette over 32 tooth . Has good chain retention spring
    and much better cable routing .

        Replacement & upgrade for broken derailleur. Works smooth and seems reliable. Like the raised shadow design. Great price for an item that gets damaged easily. As noted in other reviews, put your money into the shifter it is more important than the derailleur. And this fits the quality vs price match point.

          I installed this as a replacement for an old Shimano that was damaged beyond repair. It works like a charm on my 7 speed cassette and 1998 Shimano shifter.

            Much cheaper than the XTR that came originally with the bike but shifts just as well. It may weigh a few ounces more but seems to perform just as well as the much more expensive XTR.

            Purchased to allow an upgrade to a 12-36t cassette on my touring bike. Easy to install and adjust. Works as advertised and reaches the big cog easily. It's a little "transformer looking" which prompted the "ugly" Con, but it works well; as most Shimano items do.

                I upgraded my stock alivio to this and noticed an immediate difference in performance. I kept the stock shifters and they work fine so far in. I only have 25 miles on it but did not need to adjust during my off road ride with hills bumps and roots the whole time. Much smoother and confidence inspiring. The shadow design tucks in nicely. I had to cut existing cable to install but it was easy enough. Had to adjust H L screws for my 9 speed. Hopefully it will last awhile.

                  Only been ridden a few times but it set up easy and rides well and seems durable. Much better than the 10 year old XT dérailleur it replaced. Got my spare bike back up and running :)
