    XT Shadow Plus rear derailleur - available when?

    I see BTI lists them as do a few websites, but nothing in stock yet. Anyone have any idea when they are supposed to be available?

    I was able to find a few in stock in stores located in Europe (not sure how reputable however.) I found stores in the US that had them on their web pages, but not in stock.

    Universal Cycles has the Zee rear. IDK about the XTs. I've been waiting anxiously for the ZEE. Why not just get the Zee. A little more beefy, available in a true short cage (like the old 8 spd short cages, really short) that will accommodate 36T. UC has them listed for only $102. Not bad at all.

    Is the clutch feature only on 10 speed derailleurs?

    Mine showed up yesterday afternoon, I'm going to try to find time to install it tonight.

    And yes, I *think* it's only on 10 speed.

    Can you get away without using a chain guide on a 1x10 setup with one of these?

    I've no idea. I've only got one ride on mine and I love it, but it was a fairly tame trail. I really need to take it down a few fast rough trails to get a better idea.

    Might be possible though.

    Guess there is one way to find out ehh? The Chili sucks up the bumps pretty well so maybe we could... At the least, I bet we could get away with just a top guide.

    yeah i agree, I was thinking a top guide might work as well. Wonder what a MRP top guide costs? I'll have to look into it.

    All the adds I have read for the XT and SLX shadow+ rear derailleur say it is compatible with 9 speed shifters and cassetts. If that is true there would have to be two different ways to attach the shifter cable (two pinch bolts at different spacing). Can anyone who owns one of these derailleurs confirm this?

    I think their 10 speed only. I just fitted one on mine.
    Mine was a 2x9 set up so I fitted a 11-36 10speed cassette, 10 speed chain and 10 speed shifter. I kept the 9speed xt crank and fitted a 36 and 26 9speed rings $300 including xt plus derailleur.
    Shifts and runs like a dream best $300 upgrade ever

    No it is strictly 10spd. I noticed that all the websites said 9spd as well. I'm not sure why that it is. My SLX shadow plus was definitely 10spd.

    Thanks for the input, I also gave Shimano a call and confirmed that you are both correct. The derailleurs are 10 speed only.

    Quick question. I am looking to replace my XT RD-M780 SGS (11-36) on my Scott Scale 29er. I bent the cage and broke a few other parts, but got it back together so I can ride it. I looking at the shadow plus, but XT, ZEE, or Saint? Long cage or short? I'd like to keep it at or below $200. What is the downfall or benefit of a short cage/long cage?

    How many rings up front? Normally as the poster below mentoined 2x10 is mid cage, and 1x10 is short.

    I run 1x10 and ordered the XT Shadow+, before I realized I mis-read the info and the Zee comes in a short cage version that can handle a 36t cassette. I thought it was only good up to 34t when I originally ordered the XT.

    I like the XT, but I've got a Zee coming I will replace it with. If I can run a short cage that's what I want.

    Just received my mid cage XT Shadow + w/direct mount on my Tallboy LTc build. Seems to be just as effective as the XTR equivalent with a small step down in overall build quality. The bike is deadly quiet except for my angry bee hubs :P

    Why hasn't Shimano updated their site yet to show the XT +? And why are there only a handful of online retailers that are listing it?

    I just installed my new xt shadow plus derailleur and was surprised how tough it made the shift lever action. Haven't ridden it yet but just riding around the block I can already tell its dead quiet. Can't wait to compare it with the x9 type 2!

    I demoed a Trance X with XT stuff on it. That day I was in the park riding my singlespeed, so going to the Trance with Shadow Plus was eerily similar as far as drivetrain noise goes. Since I'm used to nothing, all I heard was the rollers on the dry chain. Awesome.
    I remember getting on my FS bike that just has a Deore RD, and how noisy it is. When I get the cash, I'm upgrading that bike for sure.

    I feel like the downshift effort would be easy to get used to. As it was, I didn't use it too much (singlespeeding makes you forget to use them), but it felt okay to me. It's kind of like an incentive to not downshift

    I'm also eager to see how Type 2 compares. The adjustability in Shadow Plus leads me to predict it will be able to outlast type 2 as far as wear goes, but I don't really know. As this tech trickles down, it will be great for everyone.

    And I wonder what Cross riders have to think about this. It seems like SRAM would have the edge here because Dyna-Sys doesn't work with road shifters, but SRAM stuff works with their road shifters.
    The first company to have a drop bar shifter/hydraulic brake/damped derailleur combo would make a killer cross bike.

    Shimano Shadow plus works with 9 speed drive train

    As most of you know, Shimano is claiming all the shadow + derailleurs are strictly 10 speed. I am one of those who refuse to 'downgrade' to a 10 speed, sorry but I'd would rather spend the couple hundred $ on something more practical. Besides I discovered it's possible to create a 2X9 9 speed drive train with a greater gear ratio compared to 10 speed. 22/36 up front, 11-34 in back. But that's for another discussion..
    Somewhere on MTB, someone posted a 'hack' to make it work with 9 speed, In short the hack consists of a 1/4" spacer where the shifter cable is bolted to the derailleur. Spacing the cable out changes the pull rate so it approximates a 9 speed version. Most importantly however the shifter must be a SRAM coupled with the the Shimano shadow + Again, this effects the pull rate.
    I recently installed a Zee short cage expecting to do the above hack, but found out it wasn't necessary. Coupled with a Sram shifter, the Zee shifting works fine without mods. So good news to those runniing a single up front and want to eliminate chain slap. BTW, I already had a chain retention device, but the Zee is far more effective. No more chain slap into spokes. Yay.

    Quick dumbass question... Does the xt plus derailleurs need specific shifters or just the normal ?

    Also does anybody know which length of cage I will need for a 2013 trek superfly al elite please ?

    So from what I have read no special shifters required lock is on the derailleur. Looks like I need the medium cage too?

    Are you using 3 rings or 2 up front? It's pretty standard to use a long cage for 3 rings and a medium for 2 or 1.

    No special shifter needed as long as its a 10 speed shimano.

    Its three rings up front with an xt crank. Looks like the medium is fine ?

    So has anyone mated the new xt shadow clutch to a 9 speed shimano shifter, cassette, and chain?

    Somewhere on these forums, someone posted a hack to make these shadow plus ders work with a 9 speed drive train. He had posted a nice photo showing the details. The issue is the shadow plus has a slightly different pull ratio compared to a standard 9 sp der. If you plan to use an xt/xtr shadow long cage der, you'll need to add a 1/4" spacer where the shifter cable is clamped to the derailluer. In addition, you'll need to swap out your Shimano shifter for a SRAM shifter. Apparently SRAM shifters have a different pull rate compared to Shimano and in this case works to increase the needed pull offset.
    If you going with shortcage der like the Zee shadow, (single chainring upfront), no need for the spacer. Just swap out the shifter for a SRAM and your good to go. Supposedly the Zee will work with a 2X10 setup, but I havent' confirmed this. I've been running a 9 spd 1X9 setup with a zee shadow plus since summer, and it's working flawlessly. You can find details on the Zee der setup in a separate thread.

    Thanks for all that.

    If I decide to go to the 10 speed (not sure I will chain strength is an issue) can I still run my xt 9 speed cranks if it is only a one ringer up front? I would have to go to a 10 speed single ring right? 9 speed is too thick?

    thanks,

    If you are already running or planning to run a single chain ring up front, don't bother with replacing anything for 10 speed. All you will need is a 9 speed SRAM shifter. I chose to stick with my 9 speed for the same reasons. That is a stronger longer lasting chain, cheaper components, etc. If you are not overly concerned about weight, get the Zee (freeride version compatible with 11-34 cassette). The Zee is a more durable version of the short cage XT, and probably cheaper too. Look at the specs, I would be surprised if it weighed more than 25 grams over the xt shadow plus.
    There are some who have converted to 2X10 using the Zee, but I see no reason a 2X9 would not work, as long as you did not exceed the gear ratio for the short cage. Search for the Zee-licous thread for details.

    Zee is basically just a short cage SLX Shadow+, with an option (at purchase) for "DH" or "FR" B-link plates. The price is equivalent to SLX.

    Saint is equivalent in price to XTR, but is very durable instead of being lightweight. They both have the best finishes (bling).
    XT is basically XTR tech with cheaper materials and finishes.

    It all depends on what ratios you are running, and the total capacity is the most important figure from the ones you linked to. That's the difference in teeth between your small/small combination, and your big/big. If you've got typical 24/32/42 XT triple cranks matched to an 11/36 cassette, then your capacity is (42+36) - (24+11) = 43T, so you'd be well over the 35T capacity of a medium cage!

    Edit: Sorry, just realised your original post was a few months ago, so its probably way too late to be telling you this...

    Hi guys, I am looking for the guy who made the pimp little block for the derailleur clamp to change the leverage a little to make perfect. I was after the exact dimensions so I can machine one at work while I am at sea.

    The basic distance you are spacing the mounting point out to is .233" away from the original position You will need to maintain the lip just like the original mounting point and also mill a step in the bottom so it keys exactly and does not spin. All of the other dimensions you can get from the actual deraileur.

    so if using a medium cage SLX shadow plus with 2 x 9 setup would you need the spacer?

    Try without it first. You may not need the spacer.
