    So if i have a 9x3sp crankset and a 10sp shifter, i'll need a 9x3sp FD correct ?

    Some who know how 9SP SLX shifters works with 10SP XT derailleurs?

    And how can i se what sp my skifters are?

    I just had to read more carefull, here is my answer.

    To repeat (again) Shimano 9 and 10 speed MTB rear derailleurs and shifters cannot be mixed in any combination!!!

    Both must be either 9 speed, or 10 speed, with the matching cassette and chain. 10 speed Shimano MTB stuff is generally compatible only with itself, although IIRC some have said that SRAM pre-10 speed derailleurs and shifters have compatible cable travel, ie, you can (in theory) use a 9 speed SRAM rear mech in a 10 speed drivetrain with Shimano 10 speed shifters, or a Shimano 10 speed mech in a 9 speed drivetrain with SRAM 9 speed shifters (though not their Shimano compatible Gripshifts).

    If you want to switch to 10 speed you will need (at least) a 10 speed rear shifter, rear derailleur, cassette and chain. Things might work better if you have matching 10 speed chainrings (or crankset), plus front derailleur, but it's quite possible the 9 speed parts will work okay.

    NB: Shimano 10 speed road rear shifters (i.e., barcons) will work when used with a Shimano 9 speed MTB rear mech as most Shimano rear derailleurs (other than 10 speed MTB and pre-1997 Dura-Ace) have compatible cable travel.

    It would be more sensible if people asking questions state what shifters, front and rear derailleurs, crankset, chain and cassette they have at present and what they are hoping to achieve by changing things rather than just asking, "Will combination x work?"

    I have a question, I'm going to buy new XTR Dynasys drive (shifters, crank, chain, cassette, rear derailleur) for my bike, but need to install as front derailleur Sram XX High Clamp Top Pull - will this combination work?

    10 speed FD with 9 speed everything else

    Hi,

    Will a 10 speed front dérailleur fit in my 2X9 SLX drivetrain?

    Explanation:
    SLX 9 speed FD direct mount is to high. I saw that SLX 10 speed FD would probably fit height wise, since it has more up-down adjustability.

    And BTW has anybody had problems with height of direct mount FD?
    I have Trek Scratch 9 frame.

    So cranks are basically all the same, you just have to buy speed specific rings?
    I have an slx (9spd) that I'm going to use for a 1x10. Buying 10 speed everything and using the slx crank with it.
    There's something about those long grueling climbs that gets my front end all stiff... And I'm not talking about lockout...

    I've currently got a 10 speed XT direct mount with a 9 speed XT crankset set up with only two rings, 22/32T and bash-ring. It works fine with some reservation. The 10 speed cage is obviously narrower than a 9 speed. I've got the high and low limits set to prevent the chain dropping off the rings. When riding on the 32T ring there is slight contact of the derailleur in the bottom two, three cogs. I could keep it as it is and use the first half of the cassette on the 22T ring but I like using all nine cogs on my 32T ring and it bugs me. I'm going to replace the derailleur with a SLX M661 9 speed direct mount.

    As to your problem with height, the mount should be a standard height and the height adjustment seems to be the same on all derailleurs. You say you are using a SLX 2 X 9 so I'm assuming you mean a 22/36 crankset. The derailleurs are designed to shift onto larger rings so it appears that the cage is high but they still shift onto and of the granny ring.
    The trouble with having an open mind is that people will insist on trying to put things in it.

    OK, so 10 speed FD won't be perfect...
    I do have 36/22 crank and I also thought that direct mount has a standard height.
    Obviously I was sure that 9 speed FD-661-D would fit, but is to high for a whole 1cm and when in granny ring the chain rubs the bottom of the FD.

    But if you compare it with 10 speed FD-661-10D you'll notice that last one has larger hole for the mounting screw and therefore I assume it can be mounted lower.

    Today on my 2008 Anthem I replaced my XT M770 9 speed triple front mech with a XT M785 10 speed double mech, my current set up is:

    XT 3x9 cranks with 26/38
    9 speed dura ace chain
    XT 9 speed 11-34 cassette
    XT 9 speed shadow rear mech
    XTR 9 speed shifters

    Works perfect, I can now use the the full range of gears with no chain rub in any gear and shifts fantastic also looks better fitted than the tripple 9 speed mech, very happy.

    You are right I have a XT M771 9 speed direct mount and the slot is shorter than on the ten speed but it works perfectly. The reason I tried the ten speed is because the M771 has a very long cage and is very close to my tire in the granny gear. I'm going to try the nine speed SLX because it has a shorter cage. When you say, "....in granny ring the chain rubs the bottom of the FD.", is that with smaller cogs selected on the cassette? If you are on the granny ring and on the top half of the cassette (lower gears), does it touch? If not, I wouldn't worry about it. You should not be cross chaining from the 22T to the smallest cassette cogs.

    Hi, when in granny ring the chain is high enough only on two largest cogs.
    Hoped that maybe 9 speed XT would fit, but from what you said I assume it's very similar to SLX.
    I also asked my local Trek dealer, but I guess he'll say that it's compatible only with 10 speed FD.
    So I'll have to go with 10 speed FD. Or maybe I'll drill another hole into the frame

    The XT M771-D front derailleur seems to have a much longer/lower cage than the SLX. It works perfectly with my 22/32T setup and the chain does not touch the bottom of the cage at all. The reason it doesn't work for me is that it was on a Banshee Paradox which is a 29" bike with chain stays less than 17". There is very little space. The cage is long and is a few millimeters from the rear tire when on the granny ring. If you have more space on a 26" bike the XT should be fine.

    Will this work?

    Here is my current set up -
    9 speed XT M770 Chainset
    9 speed XT shadow rear
    9 speed XT front mech
    9 speed XTR shifters
    9 speed XT 11-32 cassette
    9 speed KMC X9L chain

    I need to replace my front chainrings, chain and cassette as they are knackered. I have got hold of some pretty much new 10 speed XT M770 chainrings 42/32/24.

    The 10 speed rings appear to fit to my 9 speed cranks. Can I replace the rings on my 9 speed cranks with the 10 speed ones and still keep all the 9 speed stuff the same?

    Is the spacing difference on 10sp chainrings on the cranks or the rings?

    Just for info, I today I had to raise the front mech about 5mm above its intended position as the clamp would have slightly come into contact with the lower linkage on the suspension (only during full compression of the shock). Also I was initially using positions 1-2 on the XTR shifter and found that the cable become very slack when on the small ring. I guess the geometry of the 10 speed mech requires less cable to move it horizontally

    I measured the cable pull and it was 11mm for 1-2 and 8mm for 2-3, so I switched to using 2-3 on the shifter for my 2x9 setup and it works perfect, no chain rub, crisp quiet gear changes every time.

    I have got my 10speed direct mount just about perfect on my 9 speed M770 cranks. The chain barely touches the cage in the 32/34T combination and is quite acceptable. It sounds like you have a conventional clamp mounted derailleur which provides a bit more adjustment in that you can rotate the clamp. The direct mount doesn't have that option.

    What I don't agree with you on is using the 2-3 positions for shifting. How do you prevent accidentally dropping into the first (lowest) position and not realizing? Then when you want to make that critical shift, you find that you are only taking up cable. With the 1-2 position, I can limit the derailleur from going into 3 with the "H" limit screw.

    I don't think that will be too much of a problem, there are only two gears to shift between after all.

    Yes, and that is how I want it to work.

    The problem I found when shifting 1-2 was that there was a lot of lever throw whilst the shifter was taking up the all the slack, now when using 2-3 on the shifter to move into the big ring I only need a small amount of pressure and there is far less travel because of this the gear change is very fast and smooth and requires a lot less hand movement. I know the xtr M980 LH shfter has a mode switch to change from x3 to x2 which when doing so limits the shifter to use only 2-3.

    I've never really noticed but I'll give it a try. I've got XTR 970 shifters so it's a moot point. In any case, aren't XTR 980 ten speed?

    Yep you are right the M980 shifters are 10 speed but for a front mech I don't think it would make that much difference as long as it pulls a similar amount of cable as a LH M970.

    So, just installed an M985 XTR Dyna-Sys 10-speed rear derailleur mated to a SRAM X9 9-speed trigger shifter.

    Right out of the box this combo is close but not perfect. The travel of the derailleur does not match the cable pull of the shifter as it should. You can clearly see how it becomes progressively more off as it reaches the end of travel accross the cogs. It can be adjusted to just barely work. Certainly not perfect as you have to make some comproimises. Used in this manner it is very critical of adjustment. Get it just a tad off and life is not so good but it does work.

    It is so close that you CAN get it to work better with some minor changes.

    The problem is that the derailleur does not draw out enough cable during it's travel. It actually travels too much when all is said and done for this combo. I had to reduce the derailleur travel for a given amount of cable pull.

    So, I machined a derailleur anchor extension to change the cable pull related to the derailleur movement. In testing I tried anchoring the cable on the far side of the bolt (too much change). Then I began spacing the cable anchor point away in small increments. I also played with the exit location around the anchor bolt. Viola! After some playing around and experimentation I arrived upon the magic location and proceeded to machine an anchor bolt extension.

    The 10-speed XTR jockey wheel has a very small amount of float compared to the 9-speed XTR. I can swap them later on to see how that affects things if need be but for now it is good. My guess is that it will make it just that much better and more robust in terms of adjustment requirements.

    So far very happy with this slightly modified combo.

    Of course this is just my experience. Your results may vary.

    Soo..... things that make you go mmmm...

    Why not just match the shifter with the rd? Not judging but curious.... lots of work to get what sounds like subpar performance?
    I Just wish I could ride more!

    Kind of a long story but I broke my older 9-speed XTR and I found SRAM X9 at a deal. Had ridden the Dyna-sys 10 and liked it, also heard a lot about the 1:1 SRAM stuff. Shimano does not make Dyna-Sys in 9-speed that I am aware of (I may be wrong). Wanted to stay 9-speed so I went for the full SRAM X9 9-speed. It was great except the rear derailleur. For me it was sub par in a number of ways. Heard 10-speed Shimano Dyna-Sys would work with the SRAM triggers. I really ended up liking the 1:1 cable pull deal. Found a deal on a 10-speed Shimano rear derailluer so figure why not see what I can do with it. Best of both worlds for my needs.

    I am kind of a tinkerer as well so it also has some entertainment value there as well.

    I really ended up liking the SRAM triggers as much as I like Shimano derailluers so when I read this thread indicating I could have my cake and eat it too I figured why not give it a try.

    Last but not least the performance is actually better than stock SRAM so I would not say it is sub par. I am sorry if I may have given that impression. I have pretty high standards for drivetrain performance and I struggle with things I know can be better.

    I may have also missed that Shimano possibly makes Dyna-Sys in 9-speed but I am unaware if they do.

    hey there. sorry if this question I'm about to ask someone already posted, there's just zillions of posts and didn't get thru all of them...

    I basically want to get XTR 980 38-26t crankset. it's ten-speeder, of course, and I would just replace the old 9 speed crankset with it. everything else is 9 speed set-up.

    I read around the net that it'll work great, even better than the 9 speed crankset and that I don't have to change anything..
    anyone else done that? would be really cool if you did to share the experience with that kind of set-up.

    also - I read that 38-26t version is the only version that has cranks made the way it can hold a bash guard. I really hope that is the case as I need to have a bash.

    once again, sorry if somebody else made the same post before...
    thanx!
