    SRAM is up to something

    From bikemag:
    http://bikemag.com/features/onlineex..._hammer_tease/
    SRAM has just released a new website teasing a "revolution in transmission technology" called the Truvativ Hammer Schmidt. We have some guesses as to what sort of a transmission system this is, but shall remain tight lipped for a little bit longer. Here's a hint though, you can probably forget about the front derailleur...

    If you can speculate what the engineering gurus at SRAM have dreamt up for the future of MTB transmission technology leave a comment below and let us know what you think...

    Maybe in future they came with two systems, one at the front and one at the back. Like two separated Rholoff to distribute the weigh and not all on the back.

    Will see!!

    at last they release something, i asked our sram guy a few months back if there was any news on an x.0 front derailleur, he hinted that they were ditching the front derailleur. we want details.

    Let's just hope it doesn't weight more than a standard crank+front derailleur which I doubt. Like Rholoff rear hubs, it wont be a race option so not doing a X.0 front derailleur because of that would be a weird decision. My crankset, BB and front derailleur weighs about 700gr total so I don't see myself using this anytime soon... This is just speculation from my part so SRAM, feel free to prove me wrong.

    of course its going to weigh more then a standard crank and front mech, but who cares. I'm pretty sure that this is geared with the AM/FR guys in mind, who races XC anymore anyway. I'd gladly have an extra 150g for a front mech that shifts awesome (all front mechs suck btw) and dont forget that this setup would also allow you to run a shorter chain which would help you cut some grams.. An internally geared setup like this would shift instantly. DG what crank BB are you running. I honestly have a hard time believing that your crank bb and mech weigh in at 700g. I believe the CDale hollow grams weight about 660g so you must have a 40g front mech. My guess is that your crank and mech setup is really more in the 800g range. No matter, being able to design bike without worrying about front mech placement will help make frames stronger and lighter. These things are going to rock!

    Is this similar to the Miyata FM5 transmission?

    Hollowgram SL (605-615gr) with a Dura-Ace front derailleur (around 80gr). I know it's an extreme combo as far as weight is concerned and I'm also aware XC racers are not the market SRAM will be going for with that but companies have claimed years ago that their internal geared rear hubs would replace the rear derailleurs and look where we are now, 99.99% of us still use derailleurs and cassettes instead of the internal gearings. I'm also not complaining about this new option, innovation is important and it's actually very good that companies are trying new things...

    Even though I wont be using it anytime soon, this is still good news to me too.

    Some info:

    * The gearbox will be a two geared system, available in either a 12 or 14 tooth differential.
    * There will be two versions -- one using the Stylo crank platform, the other using the Hussefelt.
    * It will require that the frame have ISCG tabs for mounting.
    * It will utilize an ISIS bottom bracket.

    will the gearing be customizable? in other words if i were to go with the 12 tooth difference can i pick what those two gears equivalents are? ie-22/34; 24/36?

    is that ISCG OLD or ISCG '05 or both?

    i don't know if the difference will be up or down. i'm guessing down and therefore if you want 22/34 rings, you'd run a 34 tooth ring with the 12 tooth differential. if you want 22/36 you'd run a 36 ring with the 14 tooth differential, for 24/36 it'd 36 ring 12 tooth differential.

    Right now I’ve got what it does, I’m several miles away from my bikes so any idea if it would fit any of them:

    Trance 1/X2
    02 Slayer
    07 Stumpy- just for interest

    The reason I ask is that I’ll be asking my LBS to order a Hammer Schmidt as soon as they can if I can fit one somehow.

    Look at there spec sheets and check if the frame has ISCG mounts?

    How can you have decided you want it when Sram haven't given you guys the full details yet lol

    None of the specs say and there are just some things you know you have to have.

    Here’s a photo of the new setup, fortunately it has been blurred out for us but apparently we should see it by mid August.

    Well, that cable down the seat tube certainly isn't going to a front derailleur or shock lockout.

    I'll be watching with interest.

    The cable is still attached to a shifter up on the bars, but down at the business end of things it changes *IT" between the two ratio's as there is only 1 chainring inside *IT*

    some DH frames have wide BB shells that 2-piece cranks dont work with.

    my ISIS bearings last 10 times longer than my mud filled outboard bearings i replace 5 times a year due to crappy seals.

    or just dont get it and keep your junky shifting front setup(that includes everything made).
    or just run 1x9 or SS(thats what i do on everything but 1 bike anyway).

    Ok. Computer did it's magic processing...

    Looks like an interesting system, but perhaps a bit maintenance intensive.

    Sram do that, they will have had the info removed. They did it here too when info on Sram X.X was released by accident.

    This post will most likely be deleted too.

    Very smooth operators, I wonder what they’ll do if I post it on my blog?

    Edit: done, it’s on my blog, see if Sram goes to the trouble of asking Google or myself to remove it, not that it shows anything much.

    I think you'd find it'll end up a bit like the following: Your front will end up being something like 26/40, and your cassette will wind up being a 10sp 12-36.

    It should fit my Gemini...

    But it would be fantastic on my Soon to arrive Scapel. Perfect for marathon racing!! Thumbs up to SRAM for ditching the Front Mech.

    After the first post I initially thought that iwas some sort of sliding pulley system where the pulleys run in toward a centre on a slotted path. The gear ratio could be altered by moving the pulleys in toward the centre or away from it creating a sort of CVT. But this would do something similar. Perhaps now we can get 8 speed cassettes back??

    Nice find!

    It is surprisingly lacking in wiggidy-wacked graphics. But it must still be in stealth mode.

    Cool, that looks ultra desirable for me, I always want more compact stuff.

    Is that the Hussefelt crank version, it certainly doesn’t look like the Stylo?

    Does it have a limited range of ratios? Meant only for FR/SS/DH or will be also useful/adaptable to XC/AM/Trail bikes?

    Definitely looks interesting!

    Cable looks hittable....??! REally.

    I never seem to hit derailleur cables that run under the BB.
    The pic shows the FR/DH version. The XC version is coming but it requires an ISG mount on the BB.
    I got the whole run down on it from someone who has ridden it and spent some days with it. I trust his word and he says it's definately the future for FR/DH bikes.

    Will have to wait for the XC version to judge. I imagine that there would be more friction losses so maybe not ideal for XC just yet.

    I see that already others are making their own versions, this is the new Bionicon and Nicolai designed B-Boxx to be brought out at Eurobike in September.

    more Hammerschmidt... Look at the Shore 1 (scroll down a bit in this link...) http://www.nsmb.com/page/s/2569/norc...the-big-bikes/

    odd that it has an X-9 rear shifter but X-0 front shifter (but good to see it's a trigger shift for the hammerschidt and not twist grip)
