    Hans - Official Ibis XX1 Compatibility?

    Hans - could you confirm which models will work with SRAM XX1?

    We have several Mojo HD owners posting positive results, but I haven't seen any other models (SL, SL-R, Tranny, etc.).

    Thanks in advance!

    The frame has nothing to do with XX1 compatibility. Get the right hub and bottom bracket components and put XX1 on any bike you wish. It's just 1 x 11, it is nothing special that the bike needs designed around.

    That's what I thought as well, and then stumbled across this post in the other XX1 thread in here.

    Hi, I'm Manuel from Chile, I have a bike Ibis Mojo HD 160 and I want to install the Sram groupset XX1,

    Wrote to Ibis Cycles and they said
    "Hello Manuel,
    For XX1 the crank clearance is the same as with XX. So 156 or 168 Either will work. However, there is a clearance issue with in the 10t cog XX1. The chain will rub on the frame in That gear. We have not received any groups yet XX1. So it is hard for me to offer you specifics, but quite a few People Have Their frames modified to Work with XX1. The two methods seem to be adding a spacer Either on the end of the hub axle to spread the drop outs a little, or filing a small notch in the coal where the chain hits.
    Good Luck! "



    Since he claims the response was from Ibis, I figured I'd ping Hans and see what the scoop on this really is.

    Well, here's what we know so far - it works on our stock wheels. It's mixed on other hubs and we're getting samples of popular ones so we can make a list of go and no-go.

    More in a week or two.

    Sounds like a ton of work, but work that's very much appreciated on our end!

    I had been eyeballing the supported hub list here, and trying to decide which wheelset to go with for the upgrade. I'm still crushed to see Chris King won't be supporting this standard.

    Aways been a King fan, still run the headset, I had to change my rear King for XX1 went DT 240s, I wont be buying a King over this hub in future, its dam awesome my go too hub from now on. The DT 240s clears my frame no problem on the 10t cog.

    It's OK to file (just enough to clear) or you can try a spacer.

    We've gotten a bunch of hubs to check and will put that info out soon. Almost all of them work as is or will work with a small amount of material removed.
    More info soon.

    Not at this time, sorry. Those Ibis labeled ones are Joy tech hubs and we switched manufacturers recently.

    Speed Tune (the new one) has an xx1 free hub and it works with clearance, but is not readily available yet. We'll get them asap.

    Hey Hans - just wanted to verify you guys are testing on multiple frames (I'm personally looking for Mojo SL compatibility). Tons of info so far on Mojo HDs, but nothing yet on the trusty ol' Mojo SL.

    Salespunk, is your DT 350 a star hub or pawl, DT say the 340 is not XX1 compatible!

    Is the filing and/or spacer going to be required on the Ripley?
    I'm getting all my new parts ordered up for my Ripley build. Just ordered up my XX1 kit today along with the XX1 freehub for my older DT240s hubs that I just had laced to some of the Chinese carbon hoops.

    You are correct, it is a 350 with the star.

    Jeff here has been collecting hubs and testing fit. Here's his summary:

    We've been busy testing as many XX1 compatible freehubs on the HD as we can. Most of them fit. The determining factor will be the glue line that runs in a semi-circle around the dropout. If clearance issues do occur, they will most likely be between the glue line and the chain. Clearance is very close on the XX1 stuff, and in the event that any rubbing happens, it'll be fine to use a file in order to remove the ~1mm or so of offending glue that causes the interference.

    Hans - Official Ibis XX1 Compatibility?-dropout-clearance-4-directions.jpg

    The SLR should fit most hubs set up correctly with the XX1 driver and 142x12 end caps.

    Addedn this info on 2-15-2013 from Jeff re Mojo, SL and Tranny fit:

    Hi guys,

    I just tossed a Speed Tuned hub onto a Mojo SL and a Tranny, set them both up with the proper XX1 derailleur, crank, and chain, and all was good. Plenty of clearance.

    However, things to note:

    1.) 135x10 end caps typically are too large to fit through an XX1 lockring. Since the XX1 uses a 10 tooth high gear, rather than the standard 11 tooth, it has a smaller lockring than normal. Most manufacturers expect folks to install XX1 stuff on 142x12 bikes, so there's a good chance that the 135x10 end caps won't fit without some filing. This will differ from manufacturer to manufacturer, but it's something to be aware of. Heck, I could be wrong- the manufacturers might just make 135x10 end caps, but I haven't heard of those so far.

    2.) To answer everyone else's next question, the 156q cranks fit just fine.

    Cheers!

    Ibis

    Curiously is the Ripley being tested as well? I already picked up my XX1 buildkit that will go on mine so I suppose it doesn't matter at this point, but I am curious if I will potentially need to file

    Hans - can you comment whether you folks have tried Stan's 3.30 hubs (ZTR Arch EX wheelset) on a Mojo SL yet? Also, do you guys plan on testing clearance on Industry Nine's new Torch hubs?

    The Ripley has more room and in general has enough clearance, should be OK on the vast majority of hubs.

    We are still testing the Mojo SL and Mojo, actually waiting for the right sized hub end caps at the moment. More info as we get it.

    After just running the crank for a couple of weeks I finally got a DT swiss freehub and installed the XX1 kit. Unfortunately, downshifting shifting is not fantastic and sub-par compared to XTR, especially out of the first cog. I am wondering whether anyone else has noticed something similar?

    With XX1, the chain glides/moves horizontally across the CS/SS bridge. It doesn't get caught by the glue line as the glue line had already been worn away with my old XT casette/XTR derailleur/Mavic Crossmax hub setup.

    However, unlike with my Shimano setup, the chain gets caught between the lowest and second lowest cog (11-10) during downshifting. During the transition, there is noticeable build-up in lateral chain tension. This chain tension seems to be caused in part because the chain is pushed against the CS/SS bridge. Near the end of the transition, the chain will suddenly jump vertically upwards along the CS/SS bridge. It appears that there is some level of friction between the chain and the CS/SS bridge that contributes to the tension in the chain. At this point there is an audible pin as the tension is released. After this vertical jump, the chain then finishes its movement across to the larger cog. At higher speed this becomes less noticeable, but the downshift is not nearly as smooth as the Shimano setup. Upshifts (to smaller cogs) are no problem.

    In addition, shifting from 10th to 9th and 2nd to 1st gear could also be smoother although they are much better than the shift from 1st to 2nd.

    I have adjusted the limit screws, cable tension, and the derailleur offset. None of the adjustments fully resolved the issue. The derailleur hanger doesn't seem bent either. Has anyone else experienced this? Or is this just a characteristic of SRAM shifting?

    I am using the Chris King bottom bracket (see above), but the chainline seems appropriate (middle of the cassette @ 6th cog from the top). Hub width is 142mm. Replaced derailleur hanger to no avail.

    I have posted some pictures below.

    I am sure you did this or at least looked at it, but I had to file away some of the area of carbon and bonding area where the chain would rub the drop out area (per Hans' suggestion). I know from the angle I am seeing it, it may not be a true picture, but it looks like you are rubbing in that area. I am just thinking that may be causing you to adjust things to force the shift and therefore throwing everything else off just a little. It almost looks like you would get clicking or even up shifting on the smallest cog when back pedaling. Just a suggestion, but at least someplace to look or start. It also seems like the XX1 set up is sensitive to the "B" adjustment too, maybe take a look at that. Good luck.

    Yeah, I ground down the bonding area. The chain actually pushes against the bridge after the glue line. Interestingly enough, the glue line had already been ground away in part with my Shimano setup. I also tried different "B" adjustments. While they definitely made the issue better/worse, it really didn't fully take care of it.

    Is you shifting pretty smooth, even when pedaling slowly?

    Yes it is. I actually had to follow the chain line straight out with the file in order to clean it up enough to get no chain rub. I have almost no visible clearance but the is no rub while pedaling slowly on the stand. You might have to clean it out out a little more. Get that derailleur stop adjustment correct and then the cable tension straight and the opposite end (larger cogs) might work itself out. I do wish there was more room in that area.

    I cleaned it out as much as is possible with a dremel. The glue line is actually lower than the bridge carbon surface. As you can see from the picture below, even with the Shimano setup, there was rubbing on the carbon surface beyond the glue line. It just seems it is quite a bit worse with XX1 kit and I am wondering whether that is part of the problem. I ran two different hubs (Mavic with Shimano) and DT Swiss 240 with the XX1.

    I should add that the glue line had been completely rubbed down with the Shimano setup already. I just dremeled down the adjacent areas on the glue line. I just don't know whether this is the reason for the poor shifting or not.

    P.S. The glue line looks worse than it is due to the flash and macro level picture taking.

    XX1 is part of the issue and I had to clean a more forward in the painted (on my bike carbon) area. I used a rat tail file, then a smooth half moon shape file, from the bond line where the chain is and forward. I your case removing just the paint might be enough.

    I also filed a little more in front than just the glue line. Mainly the paint.

    What really did the job though was adding the small washer (0.5mm) on the axle towards the dropout.

    I would be interested in knowing what Anne Carro and other pros have been finding, they have been running this groupset for longer than me even.

    Id have to question peoples setups, some small differences? but thats all it takes, mine has been flawless and Ive not spaced or filed anything, its taken a beating these last few months and kept coming back asking for more, nothing Ive ridden has come close shifting is exceptional, Ive only ridden XTR, XO for the last decade so Im used to top end transmissions.

    Id like to see some measurments between a 10spd rear and bb etc & setup to the XX1 for comparison! on the same wheels, nothing can be different other than the group, diagnosis must be clear then we can see a clear picture if setups are installed correctly or not.

    I cant do this as I don't have any 10spd kit anymore, plus I don't have this problem or I would be taking it to my LBS for some direct comparisons with a digital calliper.

    Every added gear over the last 10years has become more sensitive to setup each time, 7-8 8-9 9-10 now 11spd it very sensitive to barrel adjust, b screw, chain length.

    This groupset is supposed to fit any bike that can run 10spd with same space, the only difference is a 10t cog!

    Theyre is a different ratio between gears on the cassette that might take some time to get used too, but Ive not found this its very quick imeadiate
    and for me trustworthy every time I shift. The rear d does not move like a traditional rd so comparisons are moot, this will feel different too and it does, for me thats better, if you like Shimano shifting maybe not.

    So maybe I got lucky or it was just well installed.

    Looking at this issue closer to me it seems like a spacing problem with the std rear derailluer hanger, the indentation on the hanger to guide and seat the maxle axle brings the 10t cog to close to the frame bridge for the chains stay and seat stay.

    I tried a couple of nylon washers from my spare flat pedal parts to see what difference this could make, these are quite thin hence 2 and its major, it brings the chain-line from the 10t well clear of the stays.

    So I reckon a redesigned rear d hanger is required for 11spd groups this will only become more of an issue once XO and X9 groups get released.

    I find it hard to believe no one has had an issue with 10spd setups.

    I think if you were riding in granny and the 11t gog at the rear you would get the same issue.

    Due to the 10t cog, a smaller than normal main front chain ring, benefits of XX1 its highlighting a potential problem, surely if it wasnt then other brands would be having issues as well.

    Also Im not asking Ibis to replace this as some warranty thing just another design if this is the case because its only my best eye after having a close close look at it, hence suggesting it.

    I would happily pay for a redesigned rear hanger for XX1 if this is the case, spacers just too flip floppy and easily lost not a good fix for such a stunning frame, filing no way, mine was alway close but posed no problems but I would like it std where it is now.

    Thoughts?

    I missed this but it pretty much sums up what Ive said, how can it be an XX1 issue when the glue line was already worn down by his previous Shimano setup?

    Its too close regardless, something not right with the std spacing, Ill try to get a look at a friends 10spd setup tommorrow on his Mojo HD.

    I also had to file a little in front of the glue line. Even after that it was still hitting a little when I shifted up from the 10T, but it wore everything in on it's own after that.

    Even 10 Speed was close on mine, though it did not rub paint, I originally had a frameskin piece there and the chain tore it right off, so not much room at all. A thin washer is a good temporary fix, and in the garage set up, it's fine. My only thought would what happens when your in the trail and pull off the rear wheel and lose the washer(s) in the grass or dirt. I've lost plenty of things when changing a tire. A redesigned hanger is great or even a slightly longer end cap from DT Swiss or custom one from Ibis would be more permanent. I know its supposed to be 142mm but whether its a washer or hanger redesign or end cap, we could use just a little more room. I would guess 2mm would be more than enough. I hated to file my new, unused frame!!!!!!!! I think I even cried a little, those frame are too beautiful to have to do that!

    A new hanger design would be more definite. Right now, I glued the washer with epoxy to the hanger. Like that it stays at its place.

    The ride quality easily makes up for it though.

    Good thinking, but you're right, a more permanent solution would be better.

    Great stuff guys, while I have been getting away with it, it still bothered me that others were having a problem that to me just didnt make sense and potentially I could too.

    Both solutions are a great idea bpd and like you I know I would lose or forget a washer or spacer sooner or later esspecially on the trail where Im easily distracted, I feel for you filing the frame.

    Just shouldnt have to do that, never seemed to me like a solution, not cracking on Ibis here but I was very surprised by that idea.

    I'm a big beliver when something is wrong on the trail or when building something its better to sit down with a beer in hand not so easy when riding and not rush it, break the problem down and nut it out and I'm not the most patient dude, but experience has shown this is cheaper and usually faster in the end.

    I sorta wished Id looked more into deeper sooner and normally would with any other bike build, I normally dont have 2 totally new to me components so have some sort of reference, plus I have gotten really lazy over the last few years and let my LBS do everything because theyre good and I just want to ride.

    Anyway its not hard to sort or expensive for Ibis.

    Anyone with XX1 on SL-R with I9's?
    There's a feeling I get
    When I look to the West
    And my spirit is crying for leaving

    Same rubbing issue on a 10 speed. I thought it was the XTR cassette, but swapped out to my XX and same rubbing issue when going from 11 cog to 12 (11-36 setup). The fix is to simply use a 1mm washer between the hub and drop out, but as per below, you just have to remember that there's a washer there when you remove the axle. I may just glue the washer on to the drop out next time the wheel is apart.

    What about running a non XX1 crankset with the XX1 cassette, rear D, shifter and chain? If you run no guide you'll probably drop your chain since your not using the XX1 chain ring which helps hold the chain on the ring. But if you are willing to run a full guide or a top guide wouldn't this prevent chain drops? You can run an XX1 crankset with a 10spd drivetain so why couldn't you do the opposite.

    Here's an update:

    We've found that our bikes generally fit the XX-1 without issue. The tightest set up is on the HD. As you know, it is close. It is possible to modify the frame slightly to gain clearance, or as you have noted, run a shim washer between the dropout and the hub.

    We could cnc some hangers that incorporate the greater width of the spacer so you don't have to worry about them falling off when you remove the wheel.

    Question: Is there interest for the HD spacer dropout hanger?
    If we see support for it, we'll make some.

    Regarding the hub compatibility, many of the hub suppliers have yet to get the XX-1 freehub bodies in stock as of this date 3/28/2013.

    DT (240S) is a solid choice at the moment if you are looking for good hubs to build up your wheels. We noted that the small differences in hub width and cassette location between hubs are not a problem on most of our bikes.

    Hope this helps and we welcome any comments / interest level on the need for the wider hangers for increasing clearance on HD frames.
