    Yelli Screamy Sram XX1 compatibility issue

    I have started building up my CanfieldBrothers Yelli Screamy and I have run into a problem with installing my XX1 crankset. As you can see in the pictures I have 2 drive side spacers and I am still un able to fit the cranks on without the teeth hitting the chain stay. I still need a good 4-5mm of clearances. I bought the Q156 GXP version and am now thinking that the Yelli is only compatible with the Q168 version of the XX1 cranks. Is this my problem? or is there some other work around. I dont want to buy the Q168 version and run into the same problem.

    You should cross-post this in the Canfield forum and look around some in there - I remember a recent thread concerning getting different combos to work but I think it was Shimano 2x.

    How big is the chain ring you are trying to run?

    I don't think the Q factor would matter, you might have to drop down to a 28 or 30 chainring.

    Qfactor would matter more for chainstay clearance, and after looking at your pics you probably do need the higher Q cranks as it looks mighty close there are well.

    Edit, reading comprehension sucks.

    I would put a smaller ring on it! You may be able to get by with a 30t but probably a 28t.

    It looks like you need a 28t...

    Well, you can have pointlessly short shainstays that accomodate huge tires, or you can run proper gearing.

    Arm contact will be an issue for sure.

    Damn was thinking about doing this myself, keep us posted on your solution, a 28 ring isn't the ideal one.

    Talked to my wrench buddy who ordered the group and he said that he could order the 168 Q factor and keep the other ones as stock, so it might just work out. Ill try getting him to order a 28t chainring also. Cant hurt to have it as a backup.

    SRAM lists the chainline for the XX1 as the same regardless of Q-factor, so unfortunately that isn't going to solve the issue.

    XX1 puts the chainring at a 49mm chainline. This is about 1.5mm further inboard than the middle ring of a typical 3x which is what the frame was designed around (32t in the middle ring). To compound the issue, the teeth on the XX1 ring are quite a bit taller than a typical ring(meaning it has the OD of maybe a 34t).

    Swab, it's also important to note how the GXP cranks are aligned. The drive side floats and is positioned when the non-drive side is clamped against the crank arm. Adding spacers to the drive side won't affect chain line until you've added so many that it won't assemble properly.

    Thats another issue i was have having. Because of the spacers i did not have enough spindle to install the non drive side. Ill look into taking out the spacers and installing the non drive side to see if it will fit. Hopefully i can just order a smaller chain ring and finally ride this bike!

    This is my first from scratch bike build so its a great learning experience. Ill test this out when i get home from work and will post an update.

    Swab, looks to me as if the spacers are keeping the spindle from going far enough into the non drive side bearing and allowing the spindle to center itself. From your pic it looks like the crank is at a slight angle causing the issue. I would remove the spacers and give it a go. I fit the 30T ring with your setup no problem and I think I would have enough room for the 32T as well.

    Nice! Throw insults at a person asking for help with a problem and tell them their bike is stupid. Have you ridden one? Or do you just inherently know what people should and should not ride? (in case you are wondering, my questions are rhetorical)

    I dont know if this will help but.. I am running 30t wolf tooth components chainring on shimano XT cranks(2x10). It looks like 32t would fit on mine. Wolf tooth makes chain rings to fit xx1. I am running no chain retention devise as it is not needed.

    Good luck I found this set up to be the best so far for the YS

    Very helpful. Please PM me your list of approved bikes so I don't buy anything as awesome as the Yelli next time.

    Swab, did you work this out? Curious to hear the resolution. Thinking about going XX1 on my YS.

    Yelli Screamy Sram XX1 compatibility issue

    Another option would be to try a XX1 spider for BB30 instead of GXP. These are "flatter" with less offset and will locate the chainring closer to the crank arms and farther from the stays. I am running one I picked up on eBay with XO GXP cranks on my 1x10 setup and it works just fine.

    XX1 spiders show up on eBay from time to time. Also, North Shore Billet said they were going to make XX1 compatible spiders, although I don't know if they are available yet.

    Yelli Screamy Sram XX1 compatibility issue

    Just checked NSB's site. Looks like they have GXP and BB30 spiders available.
