    Strengths:    Light
    Pretty
    Works well when it's still in one piece


    Weaknesses:    Carbon Fiber cage is a joke
    CHINA makes better CF products (sometimes)


    Bottom Line:   
    Both sides of the cage snapped on my 2nd ride with this thing when the derailleur hit a big root at maybe 2mph, -technical trail..
    Ridden same trail 100+ times without incident with metal shimano derailleurs.

    But the CF Shimano uses WILL shatter if you like to ride anything remotely technical and chose the wrong line. Justa matter of time.

    I'd bet even money against a Huffy drivetrain taking hits better than this.

    And I'm l life long shimano fan.

    Strengths:    looks cool; shifts well when dialed in

    Weaknesses:    many; expensive for little benefit over cheaper options; cost prohibitive to repair

    Bottom Line:   
    Yeah it might shift well when dialed in and look cool while doing it, but plan to do only fire road and on-road riding. I'm not a crazy aggressive rider but enjoy single track riding. Although I don't remember doing so, I must have hit a rock which broke the knuckle (bottom) of the outside cage so the chain no longer stays on the bottom pulley wheel. Shimano wants $175 to replace 1 cage!! Crazy and stupid! A new derailleur will cost $190 on most websites. Remind me to never buy Shimano's stuff again.

    Weaknesses:    Useless
    Breaks esaily


    Bottom Line:   
    Broke on the second ride, STAY AWAY from this derailleur, its light and good looking but not made to actually put on a bike. Shimano should offer an aluminum replacement part for free.

    Strengths:    Crisp shifts, Light weight, Strong for intended use

    Weaknesses:    None

    Bottom Line:   
    Crisp shifting smooth operation stylish and ultra-light weight. Used for rocky terrain, washboards, and sand. This derailleur is one tough customer. Much tougher than I thought.

    Strengths:    Light and shifts well with Shimano trigger shifters.

    Weaknesses:    The derailleur is too flimsy for any serious mountain biking. The pivot arm is weaker than the derailleur hanger it attaches to; I had one bend without any impact (i.e., just due to load), sending the cage into the spokes. The carbon fiber cage is similarly underdesigned. Mine snapped below the bottom pulley when cleanly landing a small jump. Given that the derailleur did not hit anything during the jump--in fact, it had never been hit (the bike was new)--this is inexcusable.

    Bottom Line:   
    The derailleur is only suitable for a road bike or a mountain bike that spends all day on a digital scale. Get an XT or a SRAM instead.

    Strengths:    Effortless shifts, 450 miles and only one minor adjustment needed due to cable stretch

    Weaknesses:    None. Get this derailleur!

    Bottom Line:   
    Great derailleur. This is for the 2011 M-980 series med cage on a 11-36T cassette. Took ten minutes to install and get set up and only once in 450 miles has needed any adjustment. Get this derailleur. Much better feel than XO. Been banged on rocks a couple times and still never needed any work. Ain't cheap though

    Strengths:    Light weight. Reliable. Best shifting deraileur I've used.

    Weaknesses:    Still falls somewhat short of totally seamless shifting - difficult to 'get it right' in all 3 chainrings with all nine cogs.

    Bottom Line:   
    Maybe I've been lucky, but in 18 months I haven't had any problems with the XTR Shadow deraileur. I ride 2-4 times/week all year in the Sierra's and western Nevada, much of it very rocky and rough terrain. I ride aggressively, but am a fairly 'light' rider. I've had to add protection to the underside of the frame downtube and BB, but haven't had any concerns with the rear deraileur.

    I also clean and lube the deraileur and chain after every ride.

    Weaknesses:    Broke the cage on the first ride, WITHOUT hitting anything.....its a real joke!!!

    Bottom Line:   
    Shimano should make a recall because everyone I talk to, has had the same disastrous experience within the first 3 rides. This is a real joke, DO NOT BUY THIS PIECE OF CRAP!!!

    Strengths:    None So Far

    Weaknesses:    Came on bike, snapped carbon cage on first ride, replaced it at cost because I worked in a shop and it really doesn't shift well. Either shifts well in higher or lower gears, but not both.

    Bottom Line:   
    I have never had a rear derailleur break, nor have I ever had a rear derailleur not shift perfectly with good housing. It's pretty pathetic.

    Strengths:    Light

    Weaknesses:    Very Weak, Easy to brake

    Bottom Line:   
    First off, this mech slips all the time over rougher ground. I've never hit my mech on anything (rocks, logs etc.) but after just 8 months the swing arm lost all spring tension; the cage went horizontal and the chain went slack.
    There is a tab on either end of the inner spring; this tab is prone to popping out of the hole releasing the inner spring and the swing arm goes limp!

    Waste of money, don't bother with this mech, its just a real pain to setup and a rubbish on the trails, great mech if your never going to take your bike somwhere with rough terrain, but that little tab will come loose after repeated use on rough terrain and you will end up with a useless mech half way round a 30km trail... Not fun.

    Strengths:    Smooth Shift, quick response, low profile

    Weaknesses:    Cage is super delicate, replacement parts are extremely pricey

    Bottom Line:   
    The cage got whacked by a piece of wood while I was riding, not very hard mind you, and the bottom part of the carbon cage snapped. While the light carbon is cool and aggressive in weight reduction, it doesn't really stand up against the rough riding associated with anything mountain. Go with the SLX or the XT Shadow, both have metal cages and wont break if you look at them wrong like carbon will.

    Bottom Line:   
    Like another reviewer, I have problems with the chain coming off the upper pulley on hard shifts. I have put many thousands of miles on the older XTR derailleurs and SRAM X.0 and never had this problem. This design holds a lot of promise, but Shimano needs to address this flaw.

    Date Reviewed: July 3, 2009

    Strengths:    looks cool

    Weaknesses:    carbon cage broke during rough climb causing the chain pull the derailleur around the spocket, thereby twisting the derailleur on the hanger enough so that it can't be used. Shimano's engineers need to get out and test ride their designs so that we don't have to do it form them. Oh... I almost forgot... that little "bridging" pin designed to keep the carbon separated... well it clogs with mud which also resulted in a broken hanger. Sad shimano, really sad.

    Bottom Line:   
    Buy XT or SRAM X9/XO.
