    Sram xx1 1x 11

    Apologies if this had already been posted up; didn't find the thread

    Looking forward to buying the front sprocket at the min. Hopefully they'll have a 38t out soon

    I'm pretty interested on this but i really don't like the 42t sprocket ... a 38t would be fine for me, really wondering if this setup will be any lighter than my current 1x9spd setup.
    I bet this will be expensive as f**k to upgrade too, i really wish that we'll be able to change the rear components first and then the front, my wallet would apreciate that.

    Probably not much, unless you don't run carbon cranks. It is not aimed at being lighter, but an evolution of 1x.

    I cannot see why you couldn't upgrade step-by-step.

    What I want to know though, is whether that know looking cassette/drive mechanism is compatible with existing wheels? Looks to me like the unit replaces the freehub? Would that work with any wheel? Or am I just being stoopid?

    I must say that the system looks great, but it is going to cost a fortune!

    The XX1 cassette, 650gm crank, fancy chain, new 11 spd shifter.... all i can see is a massive hole in my wallet.

    There will be no option to piece meal this together. It's 11 speed only. Must have the fancy chainring, shifters, cassette, chain and rear der.
    You know that they will use some weird bolt pattern for the chainring and since it also holds the chain from slipping, nobody is going to have a replacement for it anytime soon.
    It did appear on the video though that they will have a wide range of chainrings available.

    I just chuckle when looking at the cassette. I run a 42t big ring on my XTR crankset and that is the bail out gear.

    Yeah its going to be spendy, and it's SRAM I wonder if those chainrings are standrd bolt pattern, to fit on Shimano cranks with bashgaurd?

    compering to 2x10 the 1x11 looses one gear and as SRAM will offer several front rings, you can choose which one.

    1x11 is nice, but I just have a new 2x10..... so maybe after two years I'll thing about it.

    You can choose where your 11 speed (no overlap) range falls in comparison to a 2x10 range but how many ratios you effectively loose is completely dependant on your current setup vs new 11 sp setup.

    I'd say you have a flawed setup if you are running 2x10 with only a 12 sp effective range.

    No way I'm giving up a King hub to downgrade to sram pawls or dt ratchets.

    The crank is sweet. But you can accomplish something sleeker looking by using x0 cranks with the one piece mrp rings. I guess not having to remove the crank to change the ring is nice, although I'd never bother to do it.

    I ride 1x9, Bike came with shimano xt. (Haro Beasley 650B) I have not been pleased with the xt, Cable changeouts, constant adjustments, ghosts, and worse is having to pause when single gear shift made to varify it won't pop back.
    Everything about the bike fits me but the drivetrain. For me it would change the whole outlook of the bike with this Sram-11. I'm wondering cost, and will (MUST) try-demo the gripshift which I don't prefer, or the trigger shift to varify which is truly better. A plus is the ring choices, Less bikehike and better high gear. Maybe a Christmas gift. (But not until you gear heads review) All in all I'm excited and hoping for a real review, I'm a bit distrusting of a review from a Sram guy. No disrespect.

    Just a cassette driver body. Srm sent out the specs to all major hub manufacturers..so its only a matter of time before a good amount of hub manufactures make a new driver body available..especially if the 1x11 turns out to be a hit. Personally I like the idea for my xc racing setup. I just dont want to spend over 1500 for everything needed

    My experience with 1x 9 is much better. Much less finicky to adjust than my road 10 speed. The best thing about the 1 X 11 is the chainring selection. You can set it up for any wheel size and be comfy with the gearing. Hope it's easy to adjust and is mud proof

    I'd say you have a flawed setup if you are running 2x10 with only a 12 sp effective range.

    I try to say that you lose one gear on top or bottom range.... of course in the middle you lose more in paper but in reality not so many.
    I have Shimano 26/38 in the front and cassette is 11-36. Even if there is one overlapping which means I have 19 different gears.
    But in reality it is not the case as I'm sure you don't feel the difference if the ratio is 1.06 (how many times the rear wheel turn when the crank has made one full turn) from 1.08 or 1.36 to 1.37
    Even the ratios difference 1.19 to 1.24 or 1.53 to 1.58 it is difficult to feel the difference.
    So I would say that with 2x10 you have 15 different gears.

    1x11 against 2x10 with possibility to change the front ring according your rideÖ. I personally think it will be a hit. I just hope in two years Shimano will follow, so when my 2x10 is worn out Iíll change to it.

    I really wish they had gone more aggressive and gone down smaller than a 10 tooth small gear on the cassette. 2x10 24-38 with an 11-36 is just about perfect for me. I really want a 1x11 but going with XX1 I'd lose a lot of gears either at the bottom or the top which wont really work for the races I want to do.

    $1500 - cripes!

    I could just about do 1x10 if there was a cassette with a bit wider range than 11-36 (I'm in terrible shape - 38 or 40 teeth on the upper end would be nice). Until then, I'm pretty happy with 2x10.

    Not sure of pricing, but Hope has been working on their 9-36 cassette which will fit existing Hope hubs.

    So that could be:

    $500 Cassette
    $700 Crank
    $100 Chain
    $150 Shifter

    Then add on your new hub...

    You don't need the crank if you want this setup. That will knock off a big chunk of $.

    Now... If King jumps on board with this how much are they going to charge for freehubs ? I suspect they're going to want to go stainless on those due to the torque possibilities of a 42t cog.

    From the video it looks like the second largest cog is a 36 others have said Sram added 2 gears to the 9 cog pattern. This is a bad choice on the level going from a 11 to an 10 tooth cog gives a difference in horsepower of (11/10)^3 of 1.331 this is a big jump for humans. When climbing hills aerodynamic forces are insignificant so the jump in cog teeth should be 42/1.331 or 32 teeth continue this pattern and you find a 10 cogs are a better choice. Perhaps a 10 11 12 14 16 18 21 25 32 42

    I like the 1-x-something approach and hope this, or something like it, catches on... but I too will be waiting for an X0 or better yet X9 version. And multi-manufacturer support, at least for compatible cranks and hubs.

    I would be happy with a 11 42 cassette and a standard cassette body
    I wish they would make the splines deeper on the drive side to prevent cassette damage

    i cant wait until this crap is released. woohoo another 5 gears not really needed! and at least 10 teeth up top and 2 on the bottom that would classify as "highly unsuitable" not mentioning the goddamn chaincross that would inevitably arise cycling this crap, but hey is they make the chain out of cheese i'm game! Will it last 10miles or a whole week?

    seriously people! don't fall for this ****!

    I'm upgrading from 1x9 (where I in practice could only use 8 gears due to cross chaining) to 1x6 with the 8 sp spacing and durability. I just got myself a shitload of the best tear apart 8sp cassettes on earth, and they will last me 30 years! and not a single hickup.

    Also a 10 tooth is really crappy for efficiency,you want 12 as the smallest or even bigger, the bigger the cog/ring the lower the losses, but hey whatever floats the retardedboat right..
    Keep em coming sram I want to see the new 7-89 cassette you have brewing coupled with your new 1,2mm 17 speed chain, cant wait man!!

    A 10speed 11-38or40 would work just fine for me. Why are they making an 11speed when they could get almost the same gearing out of a 10speed. How long do you think the 11speed chain is going to last?

    So you have to buy everything new of course, isn't that obvious?

    2 weeks??

    Just wondering if i can match the XX1 rear derailleur with the XX trigger shifter and 10 speed XX cog? What i'm aiming to get here is the roller bearing clutch technology and the cage lock to eliminate chain slap. And at the same time save some money. Also i'm not keen on the 42 teeth cog.

    I was able to match 9 speed XTR trigger shifters and 9 speed cog with a 10 speed dura ace RD so i'm thinking if i can do the same with SRAM.

    From the bikerumor article the XX1 11spd Cassette looks to have the same gap between the sprockets as the 10spd, so the pull ratio for the XX1 RD should be the same as the XX 10spd RD.

    However: This would be cheaper, has a shorter cage, is available now, and is probably lighter, and matches exactly what you want

    Any word on the bolt spacing of the front chain ring? I like the possibility of running without a chainguide with my current 1x10 setup, but my assumption will be that SRAM came up with some all new bolt spacing just so people like me could not just slap on on. No way I am spending $1500 for a crank, RD, Cassette, Shifter and Chain. Then have to build an entire new rear wheel.

    bike rumor did a retract and said it would be available in April of 2013
    due to the world ending in December of this year and my ADD I just lost interest
    If there is a next summer it is getting solid real world reviews I might be back in

    I'm pretty interested in this. I wonder if the chain will even work on 10 speed chainrings? Maybe it is too narrow. Regardless, the point of this system is to not need anything other than a chainring, meaning no chain guide or FD, so it seems like the special chainring is necessary.

    I think it's funny how people are saying the chain is going to wear out in a few weeks. Didn't people say that about 10 speed?

    Also, if some of you didn't realize, you can get Type 2 RDs for 10 speed with X0 and X9 if you want the clutch chain tensioner.

    1500 seems like a lot, but it is XX, and it looks like it will be pretty light, and very quiet. I guess that's what you have to pay for 420% range with one shifter. It is competing with the Rohloff hub at this price point. The Rohloff has more than 500% range, though, and the benefits of internal gears and perfect chainline. I'd guess it's a lot heavier though.
