the 11 speed Shimano cassette (and drivetrain) runs on a standard freehub body. no need for specialist drivers or a new rear hub / new wheel
makes it very accessible to all riders.
I guess if you go the XT route you'll need a new shifter/derailleur too but not needing a RAD cage will cover most of one of those at least.
Sorry Praxis and OneUp, you need something new now. Narrow Wide chainrings will still survive, but the rest is going to die.
Multi release would be nice to have with SRAM. 5 downshifts at once is pretty sweet with SRAM but only one upshift? lame
I only use the index finger method on the workstand.
A 1x11 system with something like 44-9 would be ideal IMO. But you can't go 9t without having polygon effect noticeable. THerefore you go 56-11 if i'm not mistaken. And you throw away the 1/2" pitch chain in favour of a 10 mm one!
(yes, a 10 mm pitch 56-11 cassette has the same size as a 44-9 1/2" would have)
at this moment i am ridding a 34t wolf chainring 11-42(shimano xt cassete plus wolf tooth cog) and when this cams out(somebody know's the date?) will be my next transmission
Only problem that I see with a smaller chain is that as the diameter of the pins are smaller, the chain will be weaker, more sensitive to contaminants and less sensitive to misalignment (depending on design). It may not be a big issue as there will be more teeth to spread the load, though.
Do you notice a difference between the 36 and 32 cogs on the top of your cassette? That's a difference of 12,5 %.
*or 9 % and 11,2 %, depending on the direction you compare the two cogs, as in which is the benchmark.
cool3 with a single ring in the front?
simply i think is not that much relevant , and i am good with my set up 34 t single ring and 11-42 on the back, beeing riding and racing this way for more than a year and nothing to complain, have a 32 t chaining new to use on a race if i think is needed but never was
If you'd go SRAM's 10-42 you could have 28T front and have about the same range as you have now.
No one cares that you spin out on your sh*&ty back woods fire trail or nature park cruiser trail. And certainly the mountain bike industry should not design parts for the 90% that work for the 10% of these choppers.
As the kind of person that proposes this stupidity is probably a Strava^%hole, why don't they look at their trail speeds after their rides and really ask themselves "was I pedalling to go faster at that point?".
When you are going more than 35 kmph (30T front and 10T rear = 35.8 kmph @ 90 rpm/ 30T front and 11T rear = 32.6 kmph @90 rpm) on a real trail on an all-mtn bike you are probably not pedalling at all and if you are it is not very often, probably just a short burst to carry momentum through a slight uphill section. DH bike different story but then they run different cassettes, different front chain ring sizes (eg 36T front to 11T rear = 39.1 kmph).
So you are talking about compromising the efficeincy of an entire drive train for the 0.5% that can actually use it on a trail (ie the real expert rider at elite level) or for some corner shop run punters!
Right this particular aspect of this discussion is so pointless and so boring that I have put myself into a coma. Punters; slap yourselves in a face with an old cassette (I don't care how many teeth or speeds it has), everyone else choose the front chainring size that works for your fitness, riding ability and local terrain and go outside and enjoy your ride.
"An exciting addition for DEORE XT M8000 is a 1x11 specific 11-42T cassette "
So you can get 22 front / 40 rear, and likely 28 front / 42 rear in a 1x11.
What is your strava name. I would like to verify these 30 mph speeds on single track.
no dude you don't get it, it's to pull people's jeeps bogged down in mud and removing fallen tree trunks from the trail
Seriously though, not a pissing contest. I have nothing to prove. I hit 26.65 MPH last night on a tight, rocky trail with lots of turns and switchbacks and only 600-ish feet of vert. 30 is very doable. I've hit 30 while ON my brakes on some of the Continental Divide steep descents.
On a 29'er with a 2.2tire that would require a cadence of 116. Not impossible, but pretty high number.
Besides - 22/40 and 22/42 are not that much different TBH
(For the record a 22-40 would actually be slightly better but I want that 10t little cog on the other end)
Love my 3 sets of XT brakes. Sorry to see them add the texture bumps on the levers. I tried XTR with that setup and preferred the smooth feel of XT levers. It'll be interesting to see if they've made the servo wave's initial bite less aggressive. That seems to be the common complaint from reviewers who now prefer the sram guide. Doesn't bother me and I say no to DOT fluid. Shimano brakes and mineral oil for me...
the mechs/shifters are so close between the two brands that they are more or less negligible, they are both damn good if youre above x7/ slx,
I bought a used Felt off of Ebay. When I got it the front bearings and race were toast. It had a Shimano wheelset. I called them told them about it and they had me send in the wheel to see if it could be repaired- they ended up sending another wheel back within a week of receiving mine.
They had no obligation too.
I wish XT would just come out with a 11-42 10 speed cassette so I don't have to use the oneupcomponents 42t and get the big jump from 15-19.
Agreed. I'm sure in a few years I'll be there as well.
-no one ever.
When a company offers options to consumers and allows you to choose from a variety of ways to configure your bike = break out the pitchforks and bitch.
GX may be cheaper (except for the cassette) but that stuff looks like junk. Doesn't even have shift ramps on the 42T cassette cog.
@deeeight you might be right but I'm maybe a little less cynical... I figured it was for weight reasons. Although SRAM somehow makes 100% steel cassettes lighter without Ti and Alu (top cog is alu... but for road bikes their cassettes are all-steel and still lighter).
EDIT: Just got back from shimano and they pull ratios are NOT the same. So they are incompatible. Somebody on @lumpy873's end is misinformed unfortunately. It would have been nice..
Nick Murdick Hey Gang, I'm the instructor at Shimano TEC, We don't officially endorse the new XTR 11 speed derailleurs as being compatible with 10 speed systems because the cable pull ratio is slightly different and also because shifting slows up a bit when using it on an 11-36 cassette (you may not be able to back out the B tension screw far enough). When we're talking about a converted 10 speed 11-40/42 cassette, though, one of those problems goes away. An XTR 11 speed rear derailleur mated with a 10 speed Shimano MTB shifter will actually shift better on a converted 11-40/42 cassette than a full M980 10 speed XTR set up would.

There was more to this, but PB wouldn't let me post it all...
They probably changed from 1-to-1 to 1-to-1.05 or something minor like that. No technical benefit just enough to ensure non-backwards capability. When they went from 9 to 10 speed and changed the ratio from ~ 1-to-2 to 1-to-1 that actually made sense for better shifting. This change is just marketing.
At least get the 11spd cassette/shifter and try to get the 10spd derailleur to work if you're going to be a cheap ass and only buy some of the parts.
Would like to know more about the Dynamic Chain Engagement (DCE) concept vs. the various narrow/wide chainrings.
Ooo, what if Shimano bought xfusion?
and crc does different prices for different regions, do you guy's pay taxes from what you buy there?
We will see when this actually gets released. If it's not until next year then i don't care, but if it's released next month I'll be a little irritated.
Is the average of the market so much older now that we need 26/42 low?
I am not enthused about the ever increasing light action... the light action is so light I find it's not reliably over coming the friction of the more common full housings on many bikes. Maybe its not the light action but I do find SRAM systems seem to be much better at this.
I wish Shimano would also give us the option of continuing to use fewer cogs than 11 with our multi gear cranks. I also long for tghe days we could choose our own cassette stacks because I find these "comfortable ratio changes of 13% average" too close. I have to double and tripple shift so like the DH rider's I'd like fewer cogs so I can get across the range faster.
What road weenie decided we need 1 and 2 tooth steps any way?
-Stainless steel 1x11 chainrings
-No proprietary freehub to deal with, good ol HG
-11-42T cassette offers good range, and importantly will be affordable. Hopefully weight is not beyond 380g
What are Oneup/Wolftooth gonna do now- Shimano is offering a better functioning, more reflined and cheaper cassette...
But am I the only one who is not excited by this....
It has no more range than my 1x10 system, no improved chain retention. There is no benefit whatsoever.....
At least SRAM has got the wider range, 10-40/42 rather than 11-40/42. This is quite a significant amount.
I'm seriously underwhelmed.
They didn't say which year ;-)
Compared to a total conversion to 1x10 wide range vs 1x11 XT, the 11 stuff is slightly pricier, but I would still go for it
Can't wait for the 11 spd SLX
All black is just wrong...it suit "acera" or "alivio" groupset... Shimano, use some geinder and give us back some silver "X" on that rear der....
I bought silver XT cranks a couple of years ago and they still look decent from afar. My SRAM and XT black cranks look like crap.
What else would you like to complain about?
I wna 170 pike on my range c!
