    This is Sram XX1 just with a Specialized crank, isn't it?

    Could this be a glimps at Di2 on Absalons new bike, or is it the new electronic system from Fox?

    Looks to be the latter.
    Better to have and not need it, than to need it and not have it.

    Shimano's answer to SRAM's 1x11

    Sorry guys but that battery is just for the fox suspension. The derailleurs look to be standard XTR

Chain pins could remain the same diameter, and the plates could remain the same thickness, just shorter. The rollers would get smaller. Derailleurs and shifters could be compatible with existing setups (assuming the same number of speeds), the only thing that would have to be swapped would be jockey wheels which are nothing more than fancy plastic. That leaves the cassette, chain, and chainring to be must-haves for compatibility, which are all wear items anyway.

    Imagine a 20% shorter chain pitch allowing 20% more teeth per cog without changing the freehub body or needing larger chainrings. This would allow greater range on a cassette while better maintaining the ideal difference between gears of approximately 14%. 12,14,16,19,22,25,29,33,38,44,50 - for example. The 50t would be the size of a 40t with todays standards.

    Throw in a "floating chainring" that moves laterally to improve chainline at the extremes of the cassette and I'd be a really happy camper. Okay, I'm not sure if that one is possible, but it looks like it has been done before as seen here:
    How about the nanodrive? hee hee hee

    And apparently Shimano already tried doing a 10mm pitch chain in the 80's?

    But chain pitch only affects how many roller pins are in the chain, or how many potential points of failure from wear. Drive ratios are all about the diameters of the gears - smaller gears with more teeth are still smaller gears...

    Does GT have the answer?

    Shimano's answer to SRAM's 1x11-newgt.jpg

    Does this prototype GT drivetrain look normal XTR to you?

    No chain guide on a new Enduro weapon & the teeth on the front chainring look long. Is this a sign of the new Shimano 1x??

    There was a caption for that picture. It was something like "Dan Athertons new Enduro bike almost ready just needs a chainguide".

    I'm not sure what people are talking about here but a gear ratio is calculated off of the number of teeth in the system not the diameter of the sprocket.

    If you front was 28 and the rear was 42 it would be a 1.5:1 ratio, meaning for every time you spin the cranks 1 1/2 times the rear would go around 1 time.

    The same would be true if you front was a 30 and the rear was a 45. It would still take 1 1/2 spins of the cramk to spin the rear 1 time.

    The diameter is a result of the teeth count and the size of the teeth. Larger teeth/larger diameter will handle more torque and be stronger.

    Shimano's answer to SRAM's 1x11

    I wonder if they go to 11 speeds with next years XTR and just use the same cassette spacing as there 11 speed road group. I would love an additional 40 tooth gear and just keep the same cassette spacing as 36-11 10 speed cassette. To me this make sense.

    Talked to Shimano guys at 24 Hour this week up outside of Toronto. His reply to 'what are you guys doing to compete with XX1?', he said - "It's going to be WAY cooler and much better, just wait!" No further comment but something is in the works.

    And way more expensive? I don't really want something way cooler and better, I want a simple 10-speed 11-42 cassette that fits all my existing hubs.

    This. Though I'll accept a 10-42 since I run Hope hubs. No batteries, no custom bolt circles, no "cool" features that they'll try charging an extra $300 for. Give me a cassette that costs <$150, an SLX grade clutch derailleur and a crankset that allows a 28t ring. Done.

    They are releasing 11 speed this fall probably across the lines. Reynolds is replacing my freehub with an 11 spd freehub.I asked if that meant 11 spd was coming and yes was the answer without giving me the answer.

    I did my first ride on XX1 last night. It was great. I have no doubt that new XTR will blow everything else away.

    Anything other than this and I just won't do it. I'll even take an 11-40 cassette. Sorry. Not gunna do the General Lee cassette adapter. The tooth-number-jumps at the top are too big.

    I think we'll find out in a week or so. I believe that's when the big dealer trade shows start happening.

    Patent US5954604 - Multiple sprocket assembly for a bicycle - Google Patents

    + electronics possibly. They have a ton of electronic related patents, like an electronic motor based dropper post. Maybe when model numbers roll over from M-986 (for XTR or M-786 for XT) to M-1000 series, maybe you can expect the *start* of the revolution, beginning with the XTR groupset. Got to be patient with Shimano, as they are highly engineer based, but many of their innovations don't seem to come until they think the timing's right.

    We've already seen lot sof companies 2014 lines. I think we'd know by now about 2014.

    Maybe, maybe not. In a conversation with the Shimano rep he said that come September they are going to be releasing stuff that is going to "do some serious damage" to Sram. Reps talk like this all the time. Who really knows if that is true even if they release new items. But, given 11 spd cassette bodies are showing up on mountain wheels for a reason, I am guessing 11spd Is coming whether new XTR is coming first or not. Could be 11 speed XT at a price point much lower than XX1. I could see that doing serious damage.

    I'm absolutely certain SRAM has the design work complete for X9 1x11. They're taking their time rolling it out since it's the only game in town. If Shimano released an XT tomorrow, you'd see X9 the day after.
