    Rad for sure, but $580 for a cassette and derailleur is damn pricey. That's a lot of Zelvy guards.

    I think it's cool that the derailleur will be offered in 10 speed, since that's the only part I'm interested in. Makes a lot of sense to have the shifting movement perpindicular to the cogs. Still think I'll wait and see if this comes in x9 DH in a year or two...

    7-speed is a great application for DH, but XD driver-only will make a lot of people reluctant to consider this. Not sure the purpose for the N/W chainring and pulleys when most riders have chainguides on these bikes.

    I'm not a big fan of using narrow chains on an application that sees a lot of stress.
    The crank could easily be replaced with a narrow ring from any brand and a 10 speed cassette will still offer a quite optimal gear ratio for 99.5% of riders.
    I really like the cassette and that guard thingy, but making it only xd compatible, with a flimsy chain, meh.

    The 10 speed stuff on the other hand looks dece, hope it solves some problems the recent generations of sram derailleurs had

    now that i think about it, there's at least a few companies that make an optional driver, right?

    still, very limited compatibility at the moment

    Most companies that make 150mm hubs also make 135/142mm hubs. And chances are, their freehub bodies are are the same throughout their range, meaning the same XD driver that everyone has been buying to convert the hubs on their Enderpo/trail/xc bikes will work for the respective company's DH hubs. And as far as I know almost every Hub manufacturer I can think of makes a XD driver for their hubs (if their in the business of making money of course).

    As for the group in general, I think it's great. Road, XC, and Enderpo all have their "Gucci" drivetrains, why can't DH have one as well? I find it funny that every article on PB that featured a Pro's "Proto 7 speed drivetrain" would get 100 comments with people begging to make it available to the public. Now SRAM has, and everyone is bitching about the price and compatibility. Did people really think they would come out with a X7 level 7 speed drivetrain first? Of course not, but give it a year or two and like everything else in the cycling world, the trickle down technology will reach (semi) affordable levels. Haters gonna hate...

    Well yea, I won't argue that. I was saying that it's not an availability issue, 95% of Hub manufacturers already make the XD driver for their hubs, but yes it's an additional 50-90 bucks depending on the brand.

    You won't see 2014 bikes from big manufacturers speced with XO1 DH, because 2014 have been already produced. Some smaller/boutique makers can still deliver bikes with new components.

    This has got to be the only sport on earth where a company says, "We are gonna take some of your gears away and all the money out of your pocket!"

    And a line forms.

    seems a shame to waste all that spare freehub width. increasing flange spacing and/or reducing overall hub & bb widths seem like more optimal solutions. if you're buying into a new standard anyways. maybe even going back to 9 speed cog thickness & spacing to increase drivetrain longevity if you're going to be dropping $300 on a cassette.

    sram keeps the common sense can next to the trash can.


    and FWIW - profile used to make a 135mm wide hub that was designed specifically for 6 speed (ie hub shell took up the extra width). R.I.P.

    The new Sram XO DH deraileur is $277 MSRP.

    Chain reaction has the Shimano Zee for $67. Or an Ultegra for 79. or a Sora for 29.

    Choice made!

    Just like limited edition models of sports cars that get rid of the stereo, A/C, sound deadening, electric seats, and it's 20k more.

    So they know we want simpler drivetrains with less gears on Dh bikes. Did they miss the part about not wanting super narrow 10/11speed chains?

    One step forward, two steps back. Now come on Shimano! M830 deserves this....without the price and ridiculousness.

    Ok, I am not a gearing or drivetrain expert by any stretch but why did they make the gap in the gear set inside near the spokes and add a pretty good size guard there? I get the guard but if they would have brought the gear set in couldn't the guard have been thinner (less weight) and in turn wouldn't that have moved in the derailuer a little bit more out of the way of rocks, roots and ruts?

    Then maybe utilizing spacers like on a DJ bike or single speed? On the outer part of the cassette body by the axle/drop out

    Can someone help 'splain than to the drive train newb? Thanks

    Dat price.

    It really is the ideal drivetrain for downhill however the cost to upgrade doesn't seem worth it. That said i'll go an xx1 on my current 10 speed setup with my xo cooks it. Maybe mod it to 8 speed maybe won't, won't affect how much fun i have on my bike so probably won't bother. The x-dome cassettes look trick though.

    X-dome, x-horizon, x-acuation and x-sync +10 nerd points if you match the terms to the tech.

    Yup, I've already spec'd Shimano on my past/current builds, I like the idea of 7spd on the cassette for DH. but I'm not gonna switch to sram just because of it. maybe 2015 Shimano??

    I'm gonna stick to my old as fvck setup, after all I think there might be an eventual comeback to 9sp.

    Viva 9sp.

    Huh? Why the hate? Nobody HAS to buy it. My 9 speed SRAM/clutch shimano setup works well, I'll keep it till this technology gets to a price where I'm happy to smash into a rock without taking out a loan.

    This all makes good sense. Cassette that goes to 10t cog, so you can run a 32 on the front and reduce chain guide hits on low bikes.
    Narrow wide chainring - there are no down sides, and chains still get lost with chainguide a sometimes.
    Better derailleur movement path - well it's betterer of course.
    11 speed chain - well, yeah, that kinda sucks, but it will be compatible with all the new stuff coming out. Try buying a good 8 speed anything and you'll get what I mean. For a pure clean sheet design a dedicated 7 speed chain would be cool, but incompatible with everything else on the market and would have to cost a bomb as a very small product run.
    Big arse spacer - if a hub gets built on a wider flange spacing to take advantage of these cassettes then it will be easy to swap out the spacer.

    Oh, and price - it's a proper top end drivetrain, dedicated to downhill. It's never going to be a sensible price. Maybe in 2 years when we can buy it as x7 and the cassette weighs twice as much.

    My $30 8spd cassette, $30 sram Attack shifter (set), stronger $20 8spd chain and my $80 105 short cage have been on my Remedy and Sunday since 2010 with no issues. It's nice to be able to afford some things because they're not marketed. As for the weight? There's one less cog so it's not that much heavier. It also leaves more money in my pocket and performs spot on. This in turn leaves a bigger smile on my face when I ride.

    I also don't get all the hate...of course it's going to be expensive, it's Sram's highest end drivetrain, it's DH specific and it has a bunch of brand new tech. I've been to plenty of races where 25% of the riders (non sponsored) were riding the latest Carbon DH frame with the latest high end fork, Carbon wheels, brand new TLD kit with carbon D3 helmet. This drivetrain in for them, it's not for the guy that is riding a 4 year old frame with a clapped out fork with no rebound, skate shoes and camo cargo shorts. Just because I can't afford a Ferrari doesn't mean I don't think they're cool.

    I also have a legitimate question, why do people talk about the chain being weaker when it's narrower? Isn't the change between 10speed and 11speed just the width of the pin? If the plate size stays the same and the pin becomes shorter, wouldn't that make the pin stronger? With all else being the same, then the chain would actually be stronger?

    People have asked for this but it's not like sram is a charity and they will give it out for free. First 2 years is nerd tax, wait after that and there will be an affordable option.
