    And bolts. More aluminum for XT.

    Good find!

    It was the same for the last versions of XT and SL cranks. The difference was in the rings.

    I'd like to know what it is with the bottom bracket & triple chainrings. In other words complete. Shimano site states 889 with BB and 44-32-22. But you've probably mounted it by now.

    Your pic of the SLX's does not show/include the pre-load bolt.

    That is the reason why I buy the SLX cranks over the XT's. That, and I think the SLX cranks look better.

    So, 5 grams difference. What is the REAL difference between the two cranks? Strength?

    I dont see the crank arm fixing bolt in the SLX picture. Is that the 5 gram difference

    Personally I like the looks of the SLX better and since I'm running these SS that would be my choice over the XTs.

    You can lighten them up even further by drilling about a dozen holes in each arm.

    Best Idea I've heard so far! Speed Holes are so underrated and make a cool whistling noise when you ride fast! I'd be shocked if someone on the 29er forum hadn't already tried this

    XTR arm weight

    In case anyone was curious, I just weighed my FC 970 XTR arms, without end bolt, and they were 530 grams. Weight of entire crank w/BB was 796g. I was hoping that the XTR cranks were close to the weight of the SLX so that I could take them back and save the money and use SLX, but now I have to decide if the 55 or so grams is worth the $200 or so dollars difference. I'm using them for a SS.

    The double ring with bash SLX is what's toted as being stronger than the XT, not the 3 ring version.

    But I'm in agreement that the SLX looks a ton better than the XT stuff.

    I thought this has been said before. The only difference in weight is in the granny ring (22) which is aluminum on the xt crank,and is steel on the slx crank. I believe its a difference of 33-35 grams...I opted for the slx crank because it looks better.

    The big ring feels significantly heavier on the SLX as well. I've never weighed them but you can actually feel the difference when picking them up.

    Those are Isis and pre-hollowtech? I always thought my 770's were actually hollow. They sound hollow.

    This is very interesting news indeed. I went through a WW planning phase but in the end I decided to purchase an entire bike's worth of mid-grade parts, rather than have 1/4 of a really nice bike put together. I'm glad I went with the SLX cranks!

    Not to nitpick, but Shimano never made an ISIS crankset. You probably mean Octalink.
    Anyway, I think the SLX cranks are pretty damn sexy myself.
    I'm thinking about a set for my ss and would go w/them over XT on looks alone.
    XTR on the other hand...

    Ditto. This is the reason I went with XTs. I had some hollowtech Deores back in the day and it was the same story...just as light as the nicer stuff. Rings + hardware is where the difference is.

    I love when pricing doesn't necessarily translate to performance! Got my SLX cranks that were taken off a new bike and sold as "used" for $75 on eBay. Best investment Iv'e made yet on my bike!

    Not suprising at all about the SLX's. I use a set of Shimano XTR M952's (circa 2001) w/ a spiderless ring. The BB was around 255gr and the arms were around 400gr.

    A lot of times, the older stuff, and the cheaper stuff isn't that much heavier.

    Compare a Sette APX seatpost to a Thompson. Both are milled, one piece. APX is lighter and 4x cheaper and the wall thickness is darn close to being tghe same.

    Not both 1 piece. Wall thickness is radically different. APX = 2014 Thomson = 7005 ovalized aluminum.

    APX flexy noodle. Thomson sturdy, trusted friend.

    Now back to the cranks in the discussion.

    Question about SLX cranks...

    I plan to run 1x9 with a BB mount chainguide. Has anyone done this? Will I have to machine down the granny bolt mounting holes or should it work with no mods?

    not with SLX, but I have run such a guide with other Shimano external BB cranks. No mods needed, nor have I heard of mods being needed

    I've used the MRP before and it's not hard at all. You, of course, have to take out the drive side BB cup but other than that "tedious" step is easy as pie to set up Takes MAYBE 15 minutes if you're mechanically competent and then you never have to fiddle with it again. Set and forget

    *checks this is the 29er forum*

    WHO CARES? 5g? Even the most anti-mud-riding weight weenie will pick up that much dust on a reasonable ride! I post here for my interest in 29er bikes - I don't go near weightweenies because their pasty skin and obsessive stares scare me.

    The point is that it's not worth the price difference you might pay for XT over SLX if you're going to be using a single front ring because the weight difference for the total cranksets is in the rings. Not "OH YEAH! Buy SLX because they're 5g lighter"

    No not really, The PITA comes if you dont get it perfectly level and reinstall everything. I had my bike in my stand when I was doing it and when I put the crank back on I realized that it wasn't level. So my best advice would be to set the bike on the ground when tightening the BB cup make sure the "MRP" logo is parallel with the ground.

    Hope that helps! Adam

    I'm more asking in general; I know it's kind of apples to oranges but my Stumpy has a pressfit bottom bracket so I have a e*thirteen XCX on the seat tube. I had a really hard time getting it set to not rub the "cage" in my biggest cog but never had any problems with rub in my smallest cog. I even tried a 10spd chain with no luck. I debated between the e*thirteen and MRP products so I was just curious; trying not to kick myself for picking the "wrong" one for my bike's nuances ;-)

    So the SLX cranks are stronger, lighter, cheaper, and they look better than the XTs. They kind of legitimize the whole SLX line and have to be one of the best value components out there.

    I fully agree with you that the SLX groupset is as good as XT, the only difference is that XT is a little bit lighter. "Looks better" is a matter of opinion. However the assertion that the SLX cranks are stronger comes from the claim by Shimano that the SLX M665 two ring 22/36T all mountain crankset is stronger, which it is. I've had a set. They have a steel insert for the pedal threads and are reinforced by the bash guard. They are not the same cranks as the M660. They are also a lot heavier.

    The trouble with having an open mind is that people will insist on trying to put things in it.

    I have the XT set on my SS my rommate has the SLX set on his 3x9 and I also have the LX set.

    I got the XT set when Nashbar was blowing them out and I got to use a coupon on top of it, I like the look of the setup much more in a brush aluminum. However if weight is not an option (which most agree here) I would say the LX is a much better buy unless you get the SLX at the $99. The cranks are without a doubt heavier then my XT set but at ~$79 they're hard to beat. Since I run my XT SS I swapped the rings out and put them on the LX set, this does help with weight especially on the small ring which is steel on the LX set. I think a lot of SS'ers go for the XT due to having a 180mm crank option (that was one of my reasons).

    And as Ronnie pointed out it's the all mountain set that is stronger (M665), the notion of the M660 rumors of being stronger has been running all over this forum and simply is not true. Since the M660 is not as strong I am sure that has to do with why it is slightly lighter.

    I just got a used set, one thing I noticed was torx bolts are steel or a heavy alloy. I held all of those bolts in my hand and damn that's a lot of weight then chucked them in the trash. Did anyone have any problems with stuck torx bolts. Shimano has all but stopped using Allen bolts.

    I don't understand this new fascination with torx for crankbolts either, particularly as most multi-tools only have T25 and the crank ones are bigger.

    Just about every Torx that I have used will fit an allen key into it. The bolts on my XT's allow me to use an allen key without fear of stripping.

    The brakes on my chevy truck which use to be allen are now torx. They either have to be cut off or vice grip on the shaft long story. I did find that once you woller one out, drill out the excess and it becomes enough of an allen to get it off. Sorry as you can tell i have an extreme hatred toward the torx.

    Torx can handle torque better without stripping. While that wasn't a problem in the first place with steel chainring bolts, it can be a problem with the aluminum bolts that all the manufacturers want to use to make their cranks lighter. New multi-tool designs will adapt as needed, just like how they never had T25 Torx until they became necessary for disc rotor bolts

    Anybody weighed a set of M542 cranks? If not, I'll pull them off my bike and weigh them. I'm curious if they're much heavier than SLX cranks, if they are, I may be making a purchase.

    Those are modifed XTR cranks. The big ring bolt holes are ground off and then they're polished. Quite nice if you ask me I would like a set someday but I don't currently have a bike that would look right with a set. There is a set for sale in the Classifieds

    For what it's worth, my FC-M665, the reinforced version of the SLX, weigh 630gr. without rings. Not all that much heavier.

    Dunno about that, but (though I never verified it) I was always told LX & XT weight was comparable w/ out rings. Personally, I have been running Hone cranks w/ different rings/ bolts for years. They have a thicker spindle than the LX and are still fairly light.

    I keep my eye out on e-bay for Hones all the time...I like'em.

    LX, Hone, SLX and XT all have hollow crank arms using the same technology, however the M542 Deore arms are solid aluminum with some relief areas machined out on the back side. They are definitely heavier, though I don't know by how much

    Another great find! This thread delivers!

    The AKAs are made with AL-7050-TV aluminum as well (for the win for me)

    Guess that means I'm taking my cranks off this weekend.
