This is fugly though!

And i've just got XTR 11 speed too 🙁 😥
Yikes, that's uglier than a Volvo.
Why is the brake kit $800?!
It's a cassette, if you want a pretty one Sram will sell you a golden one which shows everyone how rad you are. 11-46 would just give me that touch more rage I'm after.
Interested to see what sort of prices DI2 XT will sell for even if I'm not sold on the idea just yet.

why so angry, it's just a groupset?
That's the new 11-46 cassette, 11-40 and 11-42 are still available. Can't disagree that the 11-46 isn't a looker...
Curious about XT Di2.
11-46 that sounds good to me. I tend not too look down when riding....

Just look at it. Makes me angry.
Never mind the cassette, SRAM cassettes are where it's at anyhow.
A wireless 1x11 mech and shifter - lose a cable, can only be good. Shifter is tidy enough, mech is bulbous but OK
There's still the issue of mangling your five hundred quid mech on a rock though.
It's tempting (assuming I don't have to sell a child to buy it); bloke who runs the LBS has XTR Di2 on his race bike and says it's great.
In all the fuss, they have quietly released 11-speed SLX too.
Any idea on when the 11-46 cassette is available?
Hmm... readign more closely, it's not really "Wireless" as the title of the article suggests.
You can set it up with your phone, but your bike is still covered in wires. I'm out.

Is it? Not how I read it. It wirelessly connects to your phone for setup and...reasons. But I think the system itself is wired.
edit - you spotted that too whilst I typed.
a snip at only two hundred and ninety three of your US dollars.There's still the issue of mangling your five hundred quid mech on a rock though.
Funnily enough the only reason I was ever interested in Di2 was when I found out you could have sequential gearing on a 2x system, but now 1x is wide enough range, there's no point.
Also - why is there only a 21g difference between the 1x and 2x chainset?!
It looks great technically, ascetically like most new bike stuff it looks crap, but it's just more aspirational crap. Seems mid range MTB's are as good as they're ever going to be, and now we're just seeing £1000 forks, £3000 frames and £1000 groupsets for the top end. Di2 isn't trickling down, it's just re-badging with a slightly cheaper price tag.
Also - why is there only a 21g difference between the 1x and 2x chainset?!
Because an alloy inner ring weighs about 20g. What did you expect?
Were we spoilt in the early 2000's when it genuinely seemed that the new bikes really were leaps ahead of old ones? Now it seems you could take a 5yr old 29er frame, slap on a neon paint job and that'd be it?

You can bang through gears miles quicker on a 1x11 DI2 setup than you can on an equivilent manual. The one thing that pisses me off about riding rolling trails with 1x11 is that I can't change quick enough for short sharp climbs.
I wamt it badly. I might go back to 2x11 and stick a tiny cassette on the back to reduce unsprung mass - but we'll see.
Oh year, no cable stretch which is a bonus.
I'm genuinely at a loss as to why people get in a huff about DI2, but seem to be keen to accept SRAMs idea of innovation (bigger heavier casettes and more gears!)
Slx chain and mech plus xtr shifter will be in my future then.
I'm loving having Di2 XTR on my Dune! Click-> next cog!
Ok, it ain't night and day over normal finger powered XTR, but i still love it!
(budget, couldn't stretch to Di2 AND Carbon Wheels, so i stuck to normal ally wheels and spent the money on the 'lecy shifting. Right choice imo)
In fact, i'm just sticking the OneUp Shark 50 toother on the back now.......
I'll be having 1x11 SLX on the Singular Swift I'm building up. Lush.
The system allows you to run multiple Junction B boxes down the line, which allows it to recognize up to six different shifters…or just keep wire management tucked discreetly inside the frame.
Six different shifters? What does this mean? Is it really good?
On the road bike you can have the STIs, sprint shifters on the drops and climbing shifter beside the stem. Or for TT'ing you can have them on the brake levers and the aerobars.
Not much use off road though now we don't have bar ends.
Ah yes - a bar end mounted shifter. Now you're talking my language.
Still no XT 11-46 mechanical cassette?
I just like the ability to jump the 3 gears or shift sequentially really fast by just holding the trigger.
Makes me smile like a complete buffoon.
The 11-46 is for mechanical or Di2. Makes no odds.
Also, Shimano now say you can run 2x with 11-42 cassette (not sure why they didn't initially). So you can have a wide ratio range, without unwieldy ratio gaps. Run that with Di2 and synchro shift for a set up you ride as if 1x, but better in terms of available ratios, shift speed/accuracy and better chainline.

thanks. Knew it'd be something obvious. 😳
Those new slx cranks to my eyes look way better than xt. The whole group set looks good and well priced too
37t jump to 46t seems a huge jump.
Looks like shimano have taken a 11-42t, taken the 42t off and slapped on a 46t..
[quote=vinnyeh]Six different shifters? What does this mean? Is it really good?
Maybe not shifters.. but electronically operated dropper, lock-outs etc?
Almost affordable, which means i'll probably go for it if I can get my XX1 mech to ever die. (3 years and counting). XX1 cassette & XT Di2 should work well 🙂
I'm genuinely at a loss as to why people get in a huff about DI2, but seem to be keen to accept SRAMs idea of innovation (bigger heavier casettes and more gears!)
Heavier cassettes? I think pretty much every SRAM 11 speed cassette weighs less than Shimano's best attempt. Shimano shifters & mech's might be great, but they don't seem to be able to make a cassette that weighs less than a boat anchor.

Wireless Brakes 😉
but they don't seem to be able to make a cassette that weighs less than a boat anchor.
Take a look at the pic, it's fairly obvious they didn't even bother to think about machining out the excess material on the big rings.
Smart battery is a nice touch seeing as the etube software doesn't work with a Mac - guess you only need 1 smart battery if you have multiple bikes to sort the firmware, not like you adjust anything on the fly anyway

You hardly expect us to use MECHANICAL cassettes with our new electronic shifting, do you?
I'm holding out until they release a fully electronic cassette and chain
You missed the word "for" despite quoting it? 😉
I didn't think it needed a smiley face.... then again, if you can have 29er specific saddles, anything is possible
Do you have to have the display for it to work? Obviously you won't be able to see the battery level but that no problem if you charge it the night before going out.

No, you can just fit a small (cheap) junction box in its place, and use your phone or garmin to see what battery or gear setting you have if you needed to.

Cool, that brings the price down a bit. Cheers.
Actually, im not sure now reading another article. It states you need the display to communicate, the battery just holds the computing power?
[edit]
That dual transmitter will be built into the XT system information display, and a new dual transmission D-Fly that’ll add wireless updates to both road and mountain bike groups. XTR will soon get a new display, too.
So you need either the display or the new D-fly unit... and the new battery.
The trick to making all of that communication work is that you’ll also need either the new BT-DN110 battery or BM-DN100 battery mount. Both contain the brains that allow those smart functions that make the wireless display work. So if you wanted to add wireless function to an existing XTR group, you’ll need to upgrade to either the new battery or new battery mount. The new battery will replace the original battery, so going forward you should see OEM spec using the new one.A new battery was necessary because they couldn’t fit any more memory into the original E-tube unit.
[edit2]
Not sure what the minimum requirements are then for setting shifter trim etc. Someone with XTR di2 can probably explain.
Also, Shimano now say you can run 2x with 11-42 cassette (not sure why they didn't initially). So you can have a wide ratio range, without unwieldy ratio gaps. Run that with Di2 and synchro shift for a set up you ride as if 1x, but better in terms of available ratios, shift speed/accuracy and better chainline.
Why would you though (I suspect shimano's reason for not saying you could was just an assumption of common sense). Going 2x on an 11-42 doesn't remove the gaps, presuming the sequential is programmed to shift the front when you get to either end of the cassette (i.e. shift up at about 22-20 and down at 36-25), not hunt for half a ratio shifting every time in the middle of the cassete?
The real question is, which is lighter, Di2 2x10 (or 11) with a conventional cassette, or 1x11 (or 12) with mechanical and a dinner plate cassette.
I read that as the battery has all the brains, and the 'computer' is just a dumb display and controller, so you could get the same functionality from an app (or if Garmin update their firmware).So you need either the display or the new D-fly unit... and the new battery.

My quote was from bikerumour, saying the wireless communication was in the display/d-fly (the original d-fly being the first wireless communicator they released), but the processing power needed for taking signals and programming is in the battery. Obviously ive no idea if they are speaking the truth though as other (less tech) websites just say the wireless is in the display and dont talk about any other components.
I completely get the benefits of electronic shifting if you are running 2x11 and programme it to only use one shifter, but when your running one by 11, how much of a difference in shifing is there?
Also does anyone know the weight differnece between mechanical and electronic? I imagine electronic is heavier?
