    Why We Like The XTR RD-M9000 Rear Derailleur

    When we're outfitting our dream race bike, we opt for the best when it comes to mechanical shifting. Shimano’s M9000 XTR Rear Derailleur is the top-of-the-line offering for Shimano's 11-speed mountain bike drivetrains. It's capable of handling cogs up to 46 teeth, and can be set up in 1 x 11, 2 x 11, and 3 x 11 configurations. Compared to the previous generation, Shimano altered the parallelogram of the derailleur a bit for more stable shifting, and also moved the top pulley wheel to allow for greater capacity without resorting to bottoming out the B-screw.

    • Rear derailleur for 11-speed Shimano mountain drivetrains
    • Accommodates a 46-tooth maximum cog size for steep cross-country climbs
    • Shadow RD+ tech with chain-stabilizer switch for control and quieter rolling
    • Long and Medium cage options to set your drivetrain to your specific needs
    • Cage profile decreased by 30mm for better rock clearance

    Long live 11 spd

    • Familiarity: I've put it through the wringer

    I understand the benefits of 12 speed but this der. and this group is super nice and with crisp clean shifting and the durability these have, what else do you need?


    • Familiarity: I've put it through the wringer

    Solid smooth consistent shifting! Super light, also looks rad. By no means a necessity over XT but hey, why not?

    The Best

    • Familiarity: I've put it through the wringer

    Best shifting, more precise, sexy, light, good price, strong...

    shifting performance is dialed

    • Familiarity: I've used it once or twice and have initial impressions

    so if you don't want to upgrade and go electronic, this is the best you can really get. Electronic shifting is nice, but the price is still high. This shifting performance is about as good as it gets before making the jump to electronic. Shimano is just so smooth.

    Almost Perfect

    • Familiarity: I've put it through the wringer

    XTR stuff is obviously great. Whether you prefer it over the SRAM offerings is purely personal preference really, I've had both recently and couldn't even say which one I prefer so I just go for whatever I can find the best deal on. I've had this derailleur for a few months now and it has performed flawlessly. My only beef, and the on area where I think SRAM is the clear winner, is in how you disengage the derailleur to remove your rear wheel. On SRAM there's a handy lock button, so you just extend it full and lock it in that position and it stays out of your way. Instead of that option, Shimano just let's you flip a lever to disengage the clutch so that there' s no resistance. This means you still have to flip the derailleur while pulling the wheel out (I know, life is SO HARD), but more importantly it means you have to remember to re-engage your clutch once your bike is back together. I always forget until I'm part way into my next ride and wonder what all the noise is about.

    That's a pretty minor, possibly even stupid, complaint so I still give it 5 stars. If you're shopping for this stuff you're probably making lots of decisions about where to splurge for XTR and where to save some pennies (lots of pennies) and go XT. Both are great really... I've always done as much XTR as the pocketbook allows to save weight, but I've also always been happy with both groups.


    • Familiarity: I've put it through the wringer

    I have been running XTR on my bikes for awhile and the quality of shifting is hard to beat. Shimano continues to bring quality product that performs at a best in class level. You will not be disappointed with this rear derailleur.

    XTR drivetrain!

      Nice looking piece of machinery. The carbon looks great. Works very smooth and it was easy to set up.

      Treat Yourself

      • Familiarity: I've put it through the wringer

      You deserve to ride XTR. You've been treating yourself right. Eating well, watching the carbs. Treat yourself with beautiful carbon and aluminum. It will shift well and is a big improvement with its super strong cam lock to keep spring tension high and your chain where it belongs.

      Buttery smooth

      • Familiarity: I've put it through the wringer

      If you are looking for buttery smooth and precise shifting, shimano XTR is for you. Carbon mixed with high end metals makes this puppy light and strong. I won't ride or buy anything else! Trade in your Sram, you won't regret it.

      Precise, smooth shifting.

      • Familiarity: I've put it through the wringer

      The functionality and efficiency that is to be expected from Shimano components paired with a sleek, aesthetically pleasing finish make the XTR M9000 derailleur a go-to component for your mountain machine. Whether you are racing XC or slaying single track, XTR flat out performs when you need it to.

      Does what it's told

      • Familiarity: I've put it through the wringer

      I have the medium cage for my 1x setup. If yuo're running a 2x, the cage length will depend on your chain wrap, and a 3x system will require the long cage. My drivetrain is a mashup of the XTR rear derailleur and chain, a SRAM X01 10-42T cassette, and a RaceFace Next SL crank. Despite being from 3 different manufacturers, everything works in harmony. The clutch on the XTR 9000 is simple to use, and keep the chain in tension and quiet. I shift, it moves, not much else you can ask of a derailleur.

      Im running a mid size raliegh detour. With x7 10 spd ext.action derail and 8 piece cassette with the stock z chain on that i would almost put the plnk slip down on.thats without the front and rear baskets and lights. E.but have a 9set with the 9x.sram.all miss matches parts but will work with correct chain that i nneed to learn how to match up correct. If it' shifts as well and as quicki as x7 is now i hope it was worth all the late night dmp,s we roaduess it would btrack only,almost maybe I'll puf that onmy ladies early90.sraliegh with thee 26 x 1.95s. . Does it sound like im on the right track without loosing comfort. I can onley imagine how fast for a first time build.

      I have a older ugly 9 speed unmatched sram selector that l m just rebuilding .but im not sure how to figur what chain.

      Jon, thanks for your insight. Super helpful!
