    Default Shimano XTR M9100 / 9120 Group

    Some cool stuff happening with Shimano's new M9100 / 9120 12 speed group.

    XTR_M9100_2x12_MARATHON_OP_zz_zz_zz_zz_zz_zz_img1-730x411.jpg

    - I'm digging the wider range cassette offerings with a switch at the rear derailleur shifter that enables it to be run as a 12 speed shifter for their 10-51t cassette or as an 11 speed shifter for their 10-45t cassette.

    - Also digging that Race and Enduro brake systems have an option that strips down the brakes or builds more power/adjustability into them. Especially like that they've kept a mtn. brake system that still uses a banjo for the Enduro (basically looks like M9000's Trail brakes beefed up) model and carries more power.

    New cassette spline which I'm sure most major hub manufacturers will offer as an option to make current hubs compatible for upgrades.

    It looks nice. I'm digging the direct mount chainrings and having 11-12 compatible shifters. Not too stoked on the hub spline license deal though. Unless they get I9 in on it before the "fall" release date. Then I'm on it!

    I imagine everyone will be on board shortly.

    This came from Pink Bike:
    Comment from I9
    "We always try to have our products align with all market needs so out wheels can be used across the spectrum. Currently, we cannot manufacture this hub body, but hopefully Shimano will open this up shortly".

    Just to be clear, XTR M9100 is apparently replacing XTR M9000 and are not compatible with each other. The 11 or 12 speed switch option is only within the new 9100 group as I understand it.

    I know DT Swiss will be making XTR compatible freehub body's according to articles. I've got a question out to my rep to find out just how long before they open things up to a larger OE audience to make compatible freehub body options. I can't see this not happening? It would be odd not to do that...

    Yup. I just like the idea of running 11 with a 10-45 cassette. I'm not mentally prepared to ride with a cassette bigger than my rotors yet. But if the day comes...I won't have to get a new shifter and I can crank the volume up to 12!

    Pretty cool that for 1x, the crank and ring can be used for 142 or 148.

    The switch is on the shifter. It just stops the ratchet from going to the 12th cog.

    What’s up with the move back to a normal derailleur hanger? Shimano was seeming pretty committed to the direct mount, even with their road stuff.

    Apparently with the move to 12 speed/wider range and the fact that they are using a 13t pulleys, the direct mount put the rear derailleur too low to the ground so it had to be scrapped. Shadow technology however is still there.

    I will say, the rear derailleur is really sharp looking:

    This article from Cycling Tips is one of the better ones that goes into all the details (and larger images) if anyone is looking for more intel.

    How about that awesome new "standard" bolt 'circle" they *just* introduced?

    You mean the one that’s not even “standard” between XT and XTR?! Luckily there’s a zillion aftermarket 1x options...

    look cool

    we have the new pedals at the shop and they are pretty clean

    one of our mechanics is at nove mesto WC right now and will have some stories when he gets back I'm sure.

    Going to be honest, with all the photos of etap eagle on nino's bike, I can't imagine buying this. maybe the brakes. I have the m8000 4 pistons on my naked and they rule

    I like to see Shimano coming up with good Mtb stuff, this groupset looks a big step forward.

    The cranks look really nice, there seems to be some good common sense there: 8mm allen key for fixing the Lh crank, two Q-factor options, and a direct-mount chainring that would use a standard Shimano lockring pattern. And, uh, I'm sure they didn't need to copy anything from Sram about the chainring tooth profile
    And let me quote this:
    they’ll offer a tool slides over the 24mm spindle, aligning it perfectly with the lock ring, so even though the ring is thin, the interface is tight and secure. Yes, they’re sticking with the 24mm spindle, no 30mm spindle options are coming
    A new preload ring is finger adjustable, with holes to stick an allen key in for extra leverage.
    and yes, because they can make chainrings that would actually shift, there is the option for a front mech. Or a nice chain guide if you stick with 1X. Nice.

    Is this a complaint/concern regarding 2x options or the new 1x spline specific to Shimano chainrings?

    If it's 2x: I'm not sure what to tell you given both Sram and now Shimano's 11 and 12-speed wide range drivetrain options? I'm surprised they still make accomodations for a front derialleur honestly. I removed my front derailleur in 1995 and I've been 1x since then - the industry finally caught up in my eyes.

    If it's the 1x chainring spline specific to Shimano: Off the top of my head: Race Face, Sram, Hope, White Industries, Cannondale, Rotor, Middleburn, S-works, e13... who am I missing? They all have their own spline patterns for attaching a single ring to a crank. Just about every major aftermarket chainring OE has all those bases covered and I'm sure once they get their hands on an M9100 crank, they'll have that base covered as well in round and oval rings.

    The only big miss initially is that the new cassette spline is not an open standard (with the exception of DT Swiss). But I'm sure this is all business/marketing strategy on their part and I'm sure that will be open in the not too distant future. Hyperglide was open. I'm sure Hyperglide+ will be too. And if not, I'm almost certain one wheel company will create a work around so as not to infringe on Shimano's patent.

    To add something in the above comment, the front shifting in today's day is so important that -whether you have to move the chain between two rings, or keep it steady in the one- the days of a "universal" chainrings are gone long time. Rings have to be specific anyway, a different BCD isn't the big deal here.
    I like that a 2x is still on offer, not everyone enjoys the 1x and since the shifting of Shimano chainrings/FD does really work, can't see why they have to follow the trend launched by people who can't make a chainring/derailleur that can shifty quick and without throwing the chain off. Long live front derailleurs that work.

    The cassette spline was a long due improvement. The HG spline cannot cope with today's demands for a large axle and low weight, plus the need to use a <11t sprocket. The 1.37" diameter had to go, so there wasn't any space for keeping the ratchet mechanism inside the freehub. And Shimano is stubborn in keeping cup&cone hubs

    None of the above, actually

    Just the extra SKU's they made for LBS's with the last bolt circle (or is it still valid for 2x?)

    Is the new front derailleur available in a band clamp?

    Haven't seen if it is.

    I love 2x, BTW

    The FD does come in band as well as D and E mount. The chain keeper does not come in band though.

    Sweet.

    The chain keeper renaissance has me kind of confused with the hi-lo teeth and the lock out on the RD but, DH......I guess......
