See just how precise shifting can be when you upgrade your bike with the Shimano XTR Shadow Rear Derailleur.

The Shadow Rear Derailleur exhibits the same precision shifting as all of Shimano's XTR components, but also includes carbon fiber construction for reduced weight. Shimano used direct routing to reduce the chances that you'll snag a cable during your ride. The XTR Shadow Rear Derailleur's low-profile design keeps it from slapping against the chain stay when you're ripping through the chunder, and the strong return spring allows effortless shifting in both directions.

Shimano XTR RD-M972 Shadow Rear Derailleur

The new XTR derailleur is great with no problems so far. Shifting on the rear derailleur is even more smooth and seamless with the XTR versus the XT previously used. I have tested the shifting capability on both flat and uphill terrain with no complaints on the performance. Definitely glad I made the upgrade.

Why a carbon cage?

Yeah, this derailleur shifts great and is awesome, but why the heck do companies keep making rear derailleurs with carbon cages?!? These are for mountain bikes people!! I had this der. for 2 months (I ran a 960 rear for 2 years until replacing it with this, but it is still in good shape) until a rock bounced up and hit the cage and broke it in half 10 miles from the finish of a 100k mtb race, and I was in 4th place at the time. Called Shimano and they said "you might as well get a new derailleur since the cage is so expensive" Then what is the point of having it be replaceable??? And, you can't use an aluminum cage from the XT Shadow because they are not mounted the same way. So basically, get the XT shadow, it shifts just as well, costs less than half as much, and it won't @#$^!&^ break in half when a little rock hits it! Oh yeah, it weighs like 20 grams more... big deal... give me an aluminum cage any day...

Totally, had the same thing happen to me yesterday, rock destroyed my cage.

Same thing for me also $200 canadian for replacement of ONE side ONE. Shimano lost a fan and I may never come back!

shifts like butter

virtually seamless shifting, rides the chain tight enough, no slip.

I agree.....just buy one. Best rear derailleur Shimano has put out (the XT shadow is really good too). Durable and mighty sexy looking on your rig.

i've been reading the xtr dual control...

i've been reading the xtr dual control shifters are not a good idea with m972 shadow (sgs) rear derailleurs. is this true? will i have 2 wait another 10 days b4 i ride?Impulsive - atl

If you are running 27 speed with a triple ring crankset in front you want to use the long cage. Using a short cage you can run out of spring when shifting to big ring and it is tough to setup to get clean shifts when in the big ring.

If you are using dual control the shifting direction will be opposite if you use a shadow. Also the spring is stronger so shifting with your lever will be more difficult. The dual control levers were built for a light action rear derailleur. Hope this helps.

Responded on

I think what these people are trying to say is, the dual control levers are designed for a low-normal (rapid rise) rear derailleur (i.e. the spring in the rear derailleur pushes it into your lowest gear/largest cog when the cable is released all the way - backwards from a regular top-normal rear d)
But, they will work just fine with either type of derailleur.

stop drooling and just buy it.

Stop looking at your buddies bike and his shiny new shadow. Just step up to the plate and buy one. They shift reliably on every ride, require very little maint, and stay out of the way. I ride a short cage with 3 rings on a Felt Virtue 2 (5" full).

does it really matter between the short...

does it really matter between the short cage and the long cage? im buying this for my husband who is a mountain bike fanatic and i want to surprise him do you have any suggestions?

Responded on

does he use 3 chainrings or 2? I would go long for 3 and short for 2. Yeah, depends on the gearing. The long cage is a safe bet since it works for all gear ranges....and its more carbon to make the ride look sweet. KC
