    Cross XX1. Coming soon?

    A week ago I suggested this to a guy on another forum. I guess Trebon is riding a prototype. Very cool. Makes sense to me.

    Spotted: Prototype SRAM cyclocross single chainring

    Interested in hearing more about this. Wonder if they will require the XX1 freehub for this too...

    Does anyone actually need a cog smaller than an 11t for 1x CX? I ran a 39t with a 12-28 and I dont think I even went onto the small side of the cassette once this year.

    39x11 is already 95 Gear Inches. If you are spinning out that gear racing CX, you are a monster.

    SRAM are doing the obvious, so it seems. I figured if they went with the XD driver and 135mm spacing... could very well see a 1x12 or possibly even 1x13 CX (then maybe road?) groupset.

    With a 36t front ring, a 12speed block may look something like:

    10, 11, 12, 13, 14, 15, 16, 17, 19, 21, 24, 28

    ... and a 13speed(!) block like:

    10, 11, 12, 13, 14, 15, 16, 17, 19, 21, 23, 25, 28

    That gives you a bit more spread than a 36t/46t with 12t-27t block. I think.

    I run a xx1 crankset (11 speed) with a type 2 xo rear derailleur, cassette, and chain (10 speed).

    So you can definitely mix and match the mtb parts. I hope the same holds true for the cross goodies.

    Same here. I'd even be interested in just the front chain rings or crank, so I can ditch my chain guide.

    You should be able to do that. Guys are using the XX1 crank with 10 speed cassettes, even Shimano cassettes and it's working.

    I don't know why guys are getting boners over the XX1 chain ring.
    It's a non ramped ring with slightly taller teeth...just like rings were 20 years ago.
    If you get your chain length right...you won't drop a chain.

    Taller teeth, yes. But the reason XX1 does not require a chainguide for most applications has more to do with the alternating width of the teeth—a feature found on some older chainrings, but absent from most everything you're likely to find today.

    The alternating width of the teeth creates a tighter interface between the chain's inner and outer plates, the result is a significant decrease in side-to-side movement. Less side-to-side movement = fewer dropped chains.

    Sorry for digging an old thread but i thought i will share with this as CX season is not that far.
    CX-rings

    Same solution as mtb XX1 style but in 110 and 130bcd. For now only 42T but in few weeks also 38T.

    But you have to run a clutch derailleur too? I've raced two seasons on a 42 single ring with a $20.00 chain guard and a $10.00 N-Gear jump stop without a single chain issue. Why would I spend hundreds of dollars to do the same thing?

    We are testing with both Clutch and no-clutch. Certainly the clutch won't hurt, but about 1/3-1/2 our mtbk customers are not using a clutch with very few chain drops.
    CX has some mechanical advantages of mtbk too (more teeth on ring engaged and short cage rear derr) so we think in most conditions no clutch will be needed.
    Clutch or not, we still think a chain catcher will be needed in REALLY clumpy muddy conditions (our mtbk data gathering tells us this, as some top World Cup teams are doing this now even with a clutch).
    Finally, all I can tell you so far is that test results with NO clutch have been very positive so far.

    40-42 in both 110 and 130BCD are on sale now shipping next week: Products | wolftoothcomponents.com

    38 and 44t will ship the following week.

    Rad!!! When will the 38t rings be back in stock? I plan to run a single front (36 or 38t) with a Paul chain keeper this season with my trusty Rival medium cage derailleur. What chain should be run with this set-up?

    The 38s will begin pre-selling next week and ship the following week.

    You probably won't need the Paul unless it gets really nasty!

    Any 10 or 11 speed chain will work.

    Same here. 38T absoluteBlack will be ready to preorder before Friday.
    As Wolf already wrote, you can run 10 or 11 speed chain. I have also stated same thing on my website that in really sticky mud there is a possibility to loose the chain, but in general you will be absolutely fine.

    Clutch rear mech - you don't need it really in cyclocross from few reasons. Chainwrap is huge compared to mtb rings (32-34 being most popular) and because you guys use short cage anyway (opposite to mtb where a lot of people have long one). So your chain is relatively short enough and tensioned enough that there is not that much possibility for rear mech to bounce. Besides it's not XC world cup terrain so the only problem may be sticky mud. But in such conditions, lets be fair - all sucks and will stop running.

    Why use it? Because you will not collect lots of mud on chain catcher and bash. Simpler and easier to clean after. Simpler to take off the crank or chain. Less expensive if you after fancy bash and chaincatcher. Less things to break or bent. LIGHTER
    If that's not enough reasons to get it then you most likely don't need it.

    I will update my website tomorrow hopefully with 38T 130 and 110 BCD

    below details of the quality you will get.

    As a veteran of more than 2 decades as a mechanic, 1x drivetrains are the best thing I've seen in a long time. Kudos to both Wolftooth and Absolute Black for giving us reasonably priced options!

    I spoke to a SRAM rep at a demo a few months back, and mentioned concocting some sort of CX XX1 solution using S700 cranks, XX1 spider, etc. After he told me it would not work, he told me to be patient, and that some cool new things were coming this fall.

    Maybe something at Interbike? Seems a little late with CX season starting around that time, but who knows.

    If they launch it it will be 120$+ ring like mtb ones. (38T mtb xx1 costs 127$ retail, so 42T will be even more expensive since it's a LOT more work time to do it)

    I also run a 1x9, 38 x 12-32, I have the 32 because my training trails have some real hills, the 38 is the smallest I can get on that sworks spider.
    For actual cx I'd be totally happy with a 36/34/32 x 12-28. There just aren't that many descents smooth enough to pedal a big gear (like a fire road descent), and almost any steeper hillclimb is going to have a barrier in front of it for a runup. At the race yesterday I saw guys preparing to start in the big ring up front (53?), I think I passed them right away. I've got a 32 in front on my 29er mtb, I intend to race cx with it on a more hilly course coming up, and I doubt I will have to shift at all in the front (12-32 rear). I rarely have to shift to the big ring on the mtb, I'm considering removing it for more log clearance, - tag logs with it more than I shift to it.

    where do you ride? As i really doubt that you can use 29er on CX courses here in Europe. there is this one rule where you have to use drop bars and max 34mm tires, so it really prevents you from using mtb bike.

    I am near Seattle in Washington State, our rules are that mountain bikes are allowed without 'forward facing bar ends', flat bar cx bikes are allowed as well.
    When I started cx in '91 (and then being out of racing for a long time after about '93) not so many guys had proper bikes, and there was a category called 'open class' for mountain bike racers who didn't have cx bikes but wanted to race cx. It was a pretty large and competitive group, at one race I knew a cat1 track guy who was with us, and there were several c1 road guys, plus the mtb guys, -quite a diverse group! At that time many of us mtb racers used 'bar ends', and plenty were removed immediately prior to the start of the first race of the season, -quite a few guys with small gaps on the ends of their bars outside of the grips. There were only 3 categories back then; cx (for those with proper bikes), open, and beginner.
    One race we did a Le Mans start, that was cool just for the history of that sort of start, I'd like to see that again even though I'm a bad runner.

    The UCI stipulates drop bars and max tire width of 33mm but in the US, mountain bikes typically can be used for any race that does not award UCI points. Of course the purists will also tell you that any course that can be raced as fast or faster on a mtb, is not a very well designed cx course.

    Don't really think you'll see anything over an 11 spd cassette anytime soon. 11 spd already pushes the limits of the space on a wheel as if affects the dish of the wheel. I'm sure a 12 or 13 is in the works somewhere, but rear wheel spacing is going to have to get considerably wider, especially if disc brakes are used.

    SHOULD be zero issues.
    I ran the opposite for a while on 2 different bikes. Sram XX MTB shifter paired with sram force derailleur. No Issues, worked 100%.

    I am building uo my new frame tomorrow with a sram force shifter, and an XO type 2 derailleur.
    Shoot me a PM if you want me to let you know how it works. Again, it SHOULD would 100%, just never tried it before.

    So, for those who wonder how absoluteBlack xx1 chainring behaves in real ride, here is my personal clip from one of the trails in Woburn Sands woods, UK.


    Bike was equipped with 38T shimano xx1 style chainring, older version of X-0 rear mech with short cage (non clutch) and a bit too long chain. I only used bottom half of the cassette to create more slack on the chain, to show that even this is not enough to drop the chain.

    I've been reading quite a bit about this stuff again and I'm still quite a noob.
    I like the idea of having only one big ring tho. I ride 70% road 30% trail/light mountain bike stuff - no competition. Hilly area - (san francisco/marin headlands) where i need to be able to ride steep stuff as well flat on the road relatively fast.
    I'm wondering if the 42t would still be okay or if that's dumb.

    In fact, I'm planning on putting it on a crux evo disc 2014 (after i rob the bank). What do you think?

    I'm running a Wolftooth 42t, 110 BCD front ring on my Trek Crockett 7 Disc with an 11-36t XX cassette in the back and an X9 Type 2 clutch short cage deraileur. Shifts great with the S700 hydro road shifters. I can't say how it works in mud, as our NorCal CX races are usually dry.

    I swapped an X9 Type 2 RD onto my cross bike two weeks ago and it's been flawless. It's paired with Rival shifters and replaced a pretty thrashed Rival RD.

    Shift lever effort increased slightly but I honestly like it. The lever feels much more connected to the derailleur with the additional effort and somehow it makes the doubletap indents easier to feel.

    I'm running a wolftooth 40T ring with rival short cage derailleur and it's been flawless, no drop chains. I haven't crashed yet, but I can't imagine the chain coming out. I think 1x11 with the new Force 22 rear derailleur and shifters would be perfect for cross. I'm not really lacking any gears with 1x10 but 1 more would be nice.

    As a followup.

    I've raced Enduro MTB all season on XX1 in conditions and courses that were very harsh (rough DH tracks, 8hrs of mud so thick you couldn't carry your bike, etc) without a dropped chain or chain guide. While a clutch rear derailleur might not be a requirement, I personally am a believer in the retention and the lack of chain slap.

    I have now been running a 42t Wolf chainring with SRAM Red 22 hydro disc brakes and a SRAM X0 type 2 rear derailleur on a Ultegra 11-28 11spd cassette. Super quiet and works flawlessly. I have not ridden the cross setup in mud yet, but it has worked very well in sand. I might also pick up a 11-32 cassette for courses which require more range, but so far the 11-28 has been adequate. The Red 22 lever does not seem to require excessive force to overcome the clutch mechanism when shifting to larger cogs. I'm super satisfied overall and love the simplicity and weight associated with not having a ft. derailleur, just as on my mt. bike. I'm pretty much a 1x convert for all but my road bike now.

    My only issue is the lack of a barrel adjuster on the X0 rear derailleur. On most frames this would not be an issue, but my frame has internal cable routing. My two ideas were some sort of inline housing barrel adjuster or taping the X0 rear derailleur for a barrel adjuster on the body. Any other suggestions?

    Inline barrel adjuster is the only option here. Either put the adjuster between the bartape and the headtube or the chainstay and the rear derailleur. I'd think having the adjuster up top would be easier for use if you need to make small adjustments during a race or longer ride. Either that or use a fourth hand tool to slightly increase cable tension at the derailleur with no means to adjust in the future.

    Your setup sounds pretty awesome, the Red22 levers feel so nice but are way outside of my budget.

    38t Wolftooth ring, 11x28, X9 type-2 short cage here. Courses in NC have been pretty rough and mostly dry to this point, and performance has been great with no dropped chains. On the subject of barrel adjusters, I have one inline near my head tube so that I can fine-tune on the fly, which I need to do depending on which wheel set I'm using.

    This is how Micals Dyck bike looked like after yesterdays muddy race on the coast of Canada using absoluteBlack chainring.
    Lots of sticky mud, grass and she used no clutch rear mech (all sram Red).

    If it can work for her, then it can work for everyone

    It seems the best gear ratio for all around is 42T chainring with a sram XG-1195 or 1190 (mtb), as fast as regular 2x10 (46-11) and a little slower (36-28), rather than using 11-28 road cassettes

    is that right? the gears in between seems relatively okay even thus the jumps are of course bigger

    42T and a cassette that suit your needs is best combo. Smaller chainrings are for very hilly races or extremely muddy like we have here in UK.

    Jagwire Rocket Adjuster fits, no drilling or tapping necessary.

    KMC issue with our chainrings RESOLVED!

    So this is a day we have been waiting for! Most of you know we did not recommend KMC chains due to too big chain rollers.
    After speaking with KMC few months back about the issue, we got today few samples of new chains directly from HQ which are going to be put to the test by us and few bike mags.

    What that means for you? It means in few months all KMC chains available on the market will be compatible with our chainrings
    Happy Thursday everyone.

    We really appreciate KMC help on that issue. This does not happen everyday where such a big company like KMC is willing to help smaller company like us and their fans to overcome the problem.

    Soon we may offer KMC chains on our web as well any propositions what would you like to see first??

    Cross XX1. Coming soon?

    After finding the XX1 a joy to use on the MTB I've been thinking about something similar for the CX bike.
    Looks like the Absolute Black chainring will be the way forward so I've got one of these on order with an 11-28 cassette.
    Should be interesting to see how it works.
