Are we allowed to talk about it now?

Or will I be flagellated?

Shimano “Dyna-Sys” XT and SLX 10 speed

Just one part of MTBing I cannot get excited about.
A 3 speed hammershimdt though, that would be progress.

Are comments now blocked on the STW page?
Anyway WTF is 'a more stable drivechain for any type of rider!" ?
Did it make more sense in the original German powerpoint slides 🙂

LOL about how it's a new system, way of shifting etc and not hjust the addition of a 10th cog.

BS!

They seem to have discontinued the SLX rear mech in GS form! That seems a bit bloody stupid.

Damn I was hoping for a double specific front mech.

This revolutionary technology not uses a 10-speed cassette, but that is not the only feature of this new system

Can't see much mention of any other new features, let alone see what's revolutionary.

as cynic-al, marketing bs.

Don't get what they're doing with the chainset, sticking with a triple, with the associated wider q-factor and bad chainlines, and yet narrowing the available ratios!

The Alfine 11 is about a thousand times more exciting than this announcement.

I'll get it at some point as I should imagine it will become the new 'standard' but really couldn't care…I set my bikes up with the high and low gear ratios I need and having an extra gear in-between those ratios really makes no difference to me.

SHIMANO

when will you listen we DO NOT WANT closer ratios, more sprockets and a narrower chain

we WANT a MORE RELIABLE system theat allows year round round geared use through the mud. wide physical spacing, wide chain and less ratios would probably be ideal

Its all about performance

– Sounds like a you tube video I saw once 😉

I must admit at first glance they do seem to have missed the point rather!

I can't imagine they'd be that far wrong, I suspect a double chainset may still come along.

seriously, how do we change this? – i'm sure that some people love 9speed systems, and will love the new 10speed systems. but i would love an alternative '5-gears-nicy-and-chunky-so-they-work' system.

is this another uk-specific thing?

Bring back 7 speed stx rc

This stuff does look different to the, *ahem* covertly distributed information that was doing the rounds before.

So to go shimano 10 speed i would need a new cassette and rear shifter?
Lose 1 chainring upfront and go 26/38 or similar – jobs a good un?

And a new chain, but yes.

nowt to get excited about imo.

It does seem strange that there are no doubles and no double mechs – hopefully they'll be a second stage press release.

So. XTR is their cutting edge, 'for race only' gruppo where all the best of the very best stuff happens. And that's staying 9-speed. What does that say exactly?

It does seem strange that there are no doubles and no double mechs

They really are missing a trick if they do not release a double front mech capable of shifting over bigger rings than 36T.

It might say that shimano haven't announced all the new stuff yet, then again it might not 🙂

Why would everyone assume that because sram went 10×2 that Shimano would?

But 10 is one more than 9. It's one better.

Because it's very clearly the main benefit of going from 9 to 10 speed.

Why sell you a double this year when they can do that next year?

That would be the Alfine 11 speed wouldn't it?

clubber, I dont see why the 10 made it logical to go 2×10 when you only have the same overall spread of gears, in fact still only the same spread as 8 speed too, just slightly closer ratios.

I would like to have it explained.

Aaaah, I hadn't realised that xtr hadn't been released yet. Oops! Might reserve a little bickering grease for when that comes out then…

Average 8 speed cassette: 11-28

Average 9 speed cassette: 11-32

Average 10 speed cassette: 11-36

There were of course bigger 8 speed ones, and 11-34 9 speed ones have become more popular recently.

Going 2×8 would mean a pretty tall bottom gear, or small rings and a low top gear. The wider spread of a 10 speed 11-36 cassette means you can have a wider range of gears on a double crank without crazy intermediate jumps.

Actually, I 'get' the chainset.

I don't race, but like doing long days over rough terrain, often with my camping gear.

That means i appreciate lots of gears, especially low ones, and don't need the high ratio of 44×11. Using a 42 big ring also means that I'll use the big ring slightly more often, and also use it in slightly smaller sprockets, instead of just sitting in big ring/fifth sprocket like I usually do.

In theory this should actually result in slightly longer drivetrain life than I'm used to, probably not what Shimano intended! 😀

er fairly sure shimano already make an 11-36 9 speed cassette, I have only ever ran 11-34 (though I am going to try an 11-28 when I get chance.) I acually have felt for ages the jump in gears between 1–34 cassettes is too much for the bits n bobs of racing I do, for general riding though its fine. so closer ratios would have suited me more a 10 speed 11-34 would probably be about my ideal, wether I would drop a front ring I dont know not dabbled with that, though I did rather enjoy 1×9.

However if the 11-36 is now the new standard cassette I do see why would assume the swap to 2×10

They do a 12-36, consequently with bigger gaps between the rings and the loss of a top gear.

Probably doesn't matter to most, but if it does, 10 speed will solve it.
