Shimano Deore RD-M592 Rear Derailleur (Black) (9 Speed) (Long Cage) (SGS)
Replaced older deore 9 speed Derailleur with M925 and so far so good. Seems sturdily built and did not have issue other review complained about in having to remove derailleur to remove wheel. Did notice proper hanging position was tilted further back than I would have thought so wheel issues may be connected to that. Shimano has online manual that is excellent for installation info and torque numbers.

Shimano Deore RD-M592 Rear Derailleur (Black) (9 Speed) (Long Cage) (SGS)
This Shimano derailleur model has a major design flaw in the one inch long connecting rod from where it screws on to the hanger down to the derailleur body. This connector allows only about 30 degrees of movement of the derailleur body and on my Specialized mountain bike, I had to remove the entire derailleur when I wanted to remove the back tire. Otherwise the jockey wheels on the derailleur cage would interfere with the cassette when lifting the wheel off the bike. You are not able to pull the derailleur back far enough to clear the cassette due to the limit movement mentioned above.

It's a totally unworkable design and I've never seen this problem occur on any other Shimano derailleur ever.

The flaw would seem to apply to any bike with a cassette.
