    SRAM XX1 cranks and 10 speed

    I was wondering if the new XX1 crankset would work with a SRAM 10spd chain and Sram 10spd cassette or would a XX1 Crankset with XX1 chain work with a SRAM 10spd Cassette?

    I believe SRAM says the xx1 chainring will work with a 10 speed chain. The xx1 chain is slightly narrower so the 10 speed will fit over the teeth without issue.

    Sounds good, would a chain device be required also with the xx1 cranks and 10spd chain or would it not drop a chain like if the cranks were run ith a xx1 chain?

    That I don't know. It would depend on your riding style and terrain. I'm sure coupled with a type 2 derailleur it would be pretty good. I wasn't able to get the chain to jump off at all with the full xx1 setup. It's also dead silent.

    ilikebmx is right on. The security of the chain on the XX1 setup is a combination of the Type2 rear derailleur AND the taller teeth of the chainring. I think you'd be pretty happy with just having the taller teeth on the front chainring.

    They can be ordered from J+B importers (find a shop who works with them). Your guess is as good as mine as to whether it will actually be in stock or not.

    Same here in EU. I was told the expected availability is around 20th.

    Also, on a not so related note, I wasn't able to find out how does the other (the left) grip look like for the XX1 gripshift. There's no need for the bulge, but I'd like to see and feel at least some symmetry there. I'm still deciding between the gripshift and the trigger.

    The other good news from this post seems to be that an xx1 spider will fit on non xx1 removeable spider cranks such as x0, the oem carbon arms, x9, aka and maybe one version of the x7 arms as well

    Anyone have any info as to whether or not SRAM plans to make the xx1 spider available as a separate piece?

    I am not much interested in the 11-speed setup, but fitting a xx1 spider / chainring to my XO cranks would be great for my 1x10 setup assuming that would mean I could ditch my chain guide.

    I would expect the aftermarket to offer a spiderless XX1 chainring, which I think would be a more elegant solution than a spider & ring.

    That would be cool, but I wonder if SRAM will license the alternating thick/thin chainring design to aftermarket producers. Aftermarket direct mount rings for 1x10 exist now, the advantage of XX1 is the ring design.

    I've got some answers from Competitive cyclist :

    "Hopefully I can help demystify the hacking of the XX1 group. The XX1 crank and chain will work as a single-speed or one-by-10 setup. If someone is currently running 9/10 on their bike, the 11-spd chain and crank will work with their cassette and derailleur. This is the ONLY part of the XX1 group that is hackable. The XX1 rear derailleur cannot be used in some fantastical creation of 1-by-whatever that someone thinks it should work with. It won’t work. You can definitely run the a Shimano or a SRAM derailleur with the chain and crank and you shouldn’t have a problem.

    With that being said, if someone is using the XX1 crank and chain in a 1-by-9 or 1-by-10 they should consider using a clutch rear derailleur, if they aren’t already. This will give them a more secure setup that the XX1 aims to achieve as a group, without needing a chainguide.

    The thing to keep in mind with using the XX1 crankset is that it has to be used with the 11-spd chain. There was talk of using a regular 10-spd chain working, but it is best to stick with the 11-spd for 1-by-whatever or single speed.""

    If the crankset works only with the 11 sp. chain, it's not really so cool, cause the 11sp. chain price is totally insane.

    I read that the 11-sp chain has the same inner width as a 10-sp chain. The plates are just a little thinner. If the inner width is the same, then why wouldn't a 10-sp chain work with the XX1 chainring?

    Exactly lol. That's why I said a 10 speed chain will work just fine. I heard it straight from a SRAM employee.

    Once they come out with X01/X91 or whatever they call the trickle down technology then I'll be in good shape.

    - Buy sprider/chainring for my existing X0/XX cranks
    - Buy 11 speed X01/X91 chain, which will be cheaper than XX1 chain
    - Buy 11 speed X01/X91 shifter and derailleur, cheaper of course
    - Buy 11 speed X01/X91 cassette, which will be "normal" vs made out of once piece unicorn tears

    So yea, once X01 or X91 whatever they call the trickle down is on the market, and I wear out my current 1x10/2x10 drivetrains, I'm all in. I'll buy it for both the trail 26er and the race 29er.

    I'm not sure the new feehub design lends itself to any other cassette design than the machined-from-one-piece type cassette. There are no splines for the 10 T cog to mount on, so at the very least the smallest cogs would have to be machined from one peice and the rest joined together like the 1080 cassette. All of the torque from the gears get transfered through the cassette up to the 42T cog, then transfered to the freehub. On the XX / XO cassettes, the 11T has splines and transmits torque to the freehub body.
    Also, while 9 and 10 speed chains will fit on the front chain ring, the "wide" teeth will not fit as snug against the outer links of the chain as it would on an 11 speed chain.

    I'm imagining a carrier setup or something could be cheaper and heavier. We'll see. Aluminium 42T is what I don't like about this setup and what I don't like about the current XX cassette. Wears out SO fast.

    42T are alot of teeth to spread out the chain load. I wouldn't be too worried about wearing that out. The SRAM Red cassette is using the same set up with an aluminum low cog, and those are available down to a 23 tooth low cog. The chainring would wear out before the 42T cog. I'm more worried about the 10T wearing out, since it's not replaceable. I tend to wear out the 11T cog on my cassettes when I run 1x9 on a bike.

    Great point! It could be a function of when I use 2x10, I spend a lot of time racing cross chained in the 39/36 and I destroy the 36T ring like that.

    I just switched over my "fun" bike to 1x10 with a 30T and the "race" bike is still on XX 2x10, but now with a PG-1070 rear cassette. With the 30T front, I venture to guess I will spend a LOT less time in the 36T because I don't use the full granny that much.

    Wondering if the sram 10-speed powerlink / powerlock chain connector is supposed to be used with the xx1 chain, or if they provide a special one for that (which seems more logical ofc). Anyone's got any info on that though?

    SS chain set up

    I hear the comments of the xx1 chain lasting longer than regular setups. Does the thought apply to running a SS setup with XX1 crankset?
    I am leaning to a 1090 or even 1070 for a little more material to take the SS torquing a little better. Am I on the right track? If not, what am I missing?

    Thanks.

    Is there a matching LEFT grip(not shifter) for 1x10 or 1x11 setups that will match the X0, XX, XX1 gripshifter?

    For shits today, we took the spider off an xx1 crank, and it does fit perfectly on an xo crank. We also ran a 10speed chain on the xx1, seems to be just fine.

    Question is, when will sram release the spider, hopefully soon.

    So next question, will the fancy XX1 chain work on the 10 speed cassette? From what I've read the 11 speed chain matches up with the front ring to help prevent chain drop.

    If I could run a regular 10 speed cassette/shifter/derailleur, I'd be totally happy to put the XX1 spider on my X0 crank and run a XX1 chain. That way I could get away without a chain guide I've found that I'm VERY satisfied with a 1x10 with a 30T front ring and 11-36 cassette. At least for the SE mountains (North GA/Pisgah/etc)

    Or, is the width of the cogs on the 10sp the same as the 11sp or not? If width is different but cog spacing is the same... its conceivable that one could run the new type RD and use limiting screws to keep to 10. Depends on cog spacing and respective throw from the RD.

    Ill go toy around at the shop in a bit and find out.

    not sure I like the left grip not being consistently thick to mirror the shifter side. Probably not, need to try it first, but I'm less inclined now.

    I assume with the 11/10 speed chain being narrower a 9 speed would work just fine? Thinking of picking up a set of the xx1 cranks for my 1x9.

    The grips come with the shifters. I imagine replacement grips will be available soon enough.

    Yep that's a single package only. At least that's what the shop says. I still haven't got mine (already got the cassette and rear derailleur fitted on my bike). Talk about distributor / channel fiasco. Everything points to January now.

    But I really can't imagine having asymmetric bar - one side thicker than the other - so I'll start with the trigger shifter and see if I stick with it. I've been always a gripshift guy though.

    What rear mech are you running? I'm interested to see if there are any dropped chain issues with older x0 or XX non clutch type rear deraileurs.

    X9 Type 2, short cage. My guess would be that a Shadow + or Type 2 is required for this setup - I don't think a standard derailleur would keep the chain on the teeth.

    No. Using an XX1 crank or ring for singlespeed is a waste. Use a plain chainring without shift ramps or any special profiling. This will be 3/32 or 1/8 thick.

    Use 1/8" wide chain. The bushed area of the inner side plate that bears on the pins is generally wider, increasing life over narrower chain. Also, the rollers are in much more contact area with the sprockets, which arguably reduces wear on them as well. However, the main reason to use 1/8 chain is because it is extremely cheap. You could buy ten singlespeed chains for one XX1 chain.

    Don't use single sprockets from cassettes either. Some frames have enough flex that a chain tensioned on the tight side could still jump off the sprocket under very rough pedaling. Use cheap singlespeed sprockets with full height teeth.

    XX1 rings were designed to retain the chain when there is variable chainline and variable chain tension, as occurs with derailleur gears. Singlespeed does not have these problems, and wide chains on wide rings have perfect chain retention unless the chain is very very loose. Loose enough that it was never properly tensioned to start with. You could tension a new singlespeed chain, and blow it through 1% wear without ever retensioning it, and not drop your chain.

    I believe both spacing and width are different. I also believe the shift ratio of the RD is different, so you can't use it in a 10 speed system. I also don't know why you would want to do this. The derailleur is huge and expensive and we have plenty of ten speed options with Type 2 or Shadow Plus.

    Ok I have just been for a 2 1/2 hour ride with my Jet9 RDO with full XX1 set up, But took the wheel with the XX1 cassette off & fitted the wheel with the 10 speed casette on it gave it a small tune & went out for my ride.

    Here is how it went.

    Shifter Rear cog
    1st 1st = mint
    2nd 2nd = mint
    3rd 3rd = mint
    4th 4th = mint
    5th 5th = mint
    6th 6th = mint
    7th 7th = mint
    8th 8th = mint
    9th 9th = mint
    10th 10th = clicking & not changing down
    11th 10th = mint

    So is well usable & can work well, not perfect but for those that want to build a XX1 bike but cant get the free hub yet, short term you can get away with running the 10 speed cassette.

    Anyone using the XX1 cranks with a MRP style guide? I understand that the chainring is designed to keep the chain from dropping, but having the protection of the taco guard is what I am after. I also noticed that on the XX1 cranks the Q-factor is narrower than the XO and X9 cranks. Will that affect chainguide set-up?

    Hi
    If you are running a Type 2 rear derailieur you really don't need the chain guide.

    There is to options for Q factor but the chain ring is in the same place for both.

    I'd recommend a chainguide for full-suspension setups, our new AMg is perfect for use with XX1. It pairs a sturdy upper guide and an integrated bashguard, it lacks a lower retention mechanism - which with XX1 rings and Type2 derailleur is a little excessive.

    The narrower Q-factor XX1 cranks do not play well with chain guides in certain configurations - especially as you get into the smaller, 30 and 28t chainrings. The upper guide runs out of room to slide down - inhibited by the crankarm shape.

    The normal Q-factor XX1 cranks are compatible with all the guides we've tested so far.
