[Closed] Is it 1st April already..? Er, no... 12 speed is apparently on its way.

I can see this being a good thing if you are running a 1x drivetrain.

catch up 😉

And I even did a 'search' on STW to check for an extant 12 speed thread, which revealed nothing. STW search engine fail.

Have we done the Shimano 13 speed 10-60 yet?

Hmm, this is starting to get silly....on my old double chainset it feels like I'm just treading water when I spin the 22 x 36 gear.... I'm not against 1x setups but with the XT 42t currently on my FS I've gone as low as when i ran multiple chain rings up front, struggling to see what this will give me except the ability to maybe run a 40t chainring....which I wouldn't do anyway?....then how wide and heavy is the rear hub area going to get with these kinds of setup?

As someone else mentioned, soon it'll be easier to go back to 2x10 for the range of gears you want, better weight distribution and it'll probably be cheaper too.

From the link posted up there,

"So what could all this advancement mean for the average rider?"

100% of f- all, all it'll do is make 11 speed 19% cheaper 😆

edit- has anyone read the 'ride your bike' bit in the new Cranked? The bit about actually having a bit of input into the ride and not just sitting there like a sack of spuds twiddling away is a good read 😀

Great, rear mechs getting even closer to the ground.

[quote=daveatextremistsdotcouk ]Have we done the Shimano 13 speed 10-60 yet?

Do keep up - Shimano has a patent for 14 speed
http://www.google.co.uk/patents/US5954604

It will get to a point, or already has, that in order to maintain a sensible unsprung weight in the rear wheel, that these cassettes, which I used to regard as service items and replace regularly with 9sp will need to made from ever more exotic materials with ever increasingly exotic price tags.
My 11sp cassette that arrived on my off the peg bike last year is £200 to replace! Not the top of the range part and its not light and the weight is not in a good place.

Gearboxes please

This is the reason SRAM introduced boost 148, a little extra space for the cassette 😀

That 14 speed patent is almost 20 years old. How come it's not on our bikes already? Shimano should have been so far ahead with 1x systems. When they saw SRAM coming out with 11 speed while Shimano still only had 10 speed shouldn't someone at Shimano have made 14 speed happen sharpish... well... you know... 20 years sharpish.

Boost 157 in a year or so isn't it?!

That 14 speed patent is almost 20 years old. How come it's not on our bikes already?

Because Shimano aren't daft, they've got to trickle down the 8,9,10,11,12 and 13-speed systems first! If you jump straight to 14, how are you going to convince people to upgrade after that?

I don't really see what all the fuss is about...

...but Shimano have been on the back foot ever since X01 appeared, SRAM are on a roll.

Having said that, SRAM are the driving force behind a multitude of new standards we don't need, so I won't be buying into any of their drivetrain stuff any time soon.

Don't think SRAM are driving standards any more than Shimano (who were responsible for 15mm with Fox)

Trek drove Boost, didn't they?

SRAM's main ne standard is the XD driver, which is a pain, but SRAM's cassettes are so far ahead of everyone else's in terms of range and weight that XD is worth the change. No cogs digging into freehubs either.

I thought SRAM drove the Boost 110 standard?

The SRAM cassettes may well have one fewer cogs at the top end, but the fact that replacements are expensive kills the appeal for me.

They're not expensive any more, relative to Shimano

99.95 Eur for GX 10-42 Cassette and chain, versus 84.95 for the heavier, narrower range XT 11-42 (without chain).

https://www.bike-components.de/en/Shimano/XT-Kassette-CS-M8000-11-fach-Modell-2016-p43966/

Oh christ! just think of all the 'Chain line' threads for that!

I can't see a quoted weight on the GX, but I'll happily take it as read that it's lighter than 447g.

I'd also need to factor in the cost of the compatible freehub body for my hub too...

...but 99.99 EUR for cassette and chain is good going. I hadn't realized that the price had fallen that much.

Like a few have already said, I'm not interested in throwing more and more weight at the rear wheel on a full suss bike. One of my shed projects is a 2 x 5 build using a 'short' cassette hub. Similar range as a 1 by system with sprockets picked to be sequential - front mech shift also sends the rear mech to gear 1.....mechanically (don't ask, if I could afford Di2, I'd be using them).
Rear wheel's stronger due to the better flange spacing on the "SC" hub.

Oh and +1 to gear boxes. The other shed project is a Alfine based full suss similar to Rob Metz's Zerodes.

"..but 99.99 EUR for cassette and chain is good going. I hadn't realized that the price had fallen that much."

Don't forget the 14.95Euro postage!

9.95 postage

393g claimed weight for the GX, so a decent saving versus XT

That would be the gear range I would want on my bike.

But I'm still not sure that it solves a problem that I have as I don't find front shifting that hard

and this...

It's a bit of a giggle innnit.

I mean, won't we just have dished in rear wheels and a 40 cog sprocket occupying the space where the bearing went??

Also, if they get any bigger we'll be riding around on a 600T cog and no rear tyre. Be good for ploughing, great for climbing but shite for DH.

Cool kids? On STW?

Solves a lot fo issues for full suss frame design though - means they can drop providing for FDs altogether.

Range was the only real disadvantage if 1x, and 10-42 solved that for almost everyone - less cabling, lower eight, more clearance, less mud clogging, no duplicated gears, no need to shift to mechs - can't see why youd want a 2x system

It's those nasty manufacturers isn't it, trying to bleed more money out of us. They have realised that unlike 650b where people got upset and refused to buy a new bike ever again, or tapered headsets and boost where people got a bit sniffy about change they have hit pointless change gold with 1x as the masses lap it up and are quite happy to spend vast sums replacing serviceable equipment with an 'upgrade' that has no real benefit 😉

If they could just find away of turning the drivetrain round so there was a single cog at the back and the cassette bit at the front that would be excellent. You would have alot less unsprung weight and a stronger lighter wheel via better geometry as the hub flanges could be much further apart.

I will leave it to engineering minds far superior to mine as to how you fit 11 or 12 cogs, cranks and the changing mechanism round the BB.

can't see why youd want a 2x system...

I do miss the ability to make a 'big' gear change, with only 1 click (middle ring to granny, specifically)

You can downshift about four gears with one thumb push, which is equivalent.

Anyone bought this GX cassette from ebay?? [url= http://www.ebay.co.uk/itm/New-SRAM-GX-XG-1150-FULL-PIN-Cassette-10-42T-11-Speed-Mountain-Bike-MTB-/172026186475?hash=item280d8f4aeb:g:TH4AAOSwgyxWXWjR ]here[/url]

Similar price from bike-components-de.

It might make sense if you have a 29er that can't take a front mech and want to ride it all day over big mountains.

I have a 28x42 bottom gear on my Smuggler, which is fine most of the time, but I could still use something a touch lower at the end of a long day. A 28x44 bottom gear would work, but i understand that my suspension was designed around a 32 tooth chainring. In order to run that I'd need a 50T sprocket, but who is going to make one of them ?

Those going on about unsprung weight, you know you are 6 weeks early?

How many people went 1x11 this year?
I might hold out for a while now...

Still on 3x9 here. Crazy I know.

Actually, I've just gone 2x9 on my latest build.. 😯

I will finally succumb to modernity when everything settles down a bit and we have standardised multi-dimensional hover-wheels with self-levelling suspension.

i nearly went 2x10 but decided to stay with 3x9 and 3x10 as it weighs naff all more. I might make the jump to 1xWhatever when everything and my spares are worn out but until then it just makes more sense to have a triple up front in terms of drivetrain life as used properly it causes minimal wear.

I'm just happy 10sp stuff is getting cheaper.

I'm so glad that I didn't upgrade anything but it's looking a bit silly now.

I thought 9-10 spd was fine and hey ho 11spd?

What next? 50 speed?

Doesn't it just seem a bit pointless? I can see the real benefit of going to 1x on the front but what real function does 12 speed serve over 11 speed? (and if you like 11 over 10 and 10 over 9 etc etc)
You don't see people stopped on hills going 'well I would have been able to get up there if I had 12 gears instead of 11'

3x9 here as well through choice.

I like 1x on the front but I've always had 1x on the front where possible. My old 90s Giant Boulder Al was 1x7 (roots!), so was my GT Chucker. I'm a bit of a dual slalom/DH fashion victim, see? 😆

Bikes, innit. Whatever you're riding is good, just don't look down on or up to others that have different stuff to you.

The amount of people pushing very expensive looking 1x bikes up the inclines at Llandeglla at the weekend would say some people need quite a few more gears.

Boost 157 in a year or so isn't it?!

aka "Turbo Boost"

And a new BB standard to go with it.

😆 to both of those ^^

Actually, I've just gone 2x9 on my latest build..

My last build was 3x9.

And friction shifters!

Only went 9speed as a concession to modern times and the unavailability of decent screw on freewheels forcing new hubs. On the upside, 10,11,12,13,14 speeds should all still work on the same shifters when the next upgrade is forced!

Hey, I got round llandegla withput pushing on my expensive 1x bike on sunday, but I did get overtaken on that climb by a guy on an old Trek hardtail, I was a wee bit jealous of his granny ring !

[I] they have hit pointless change gold with 1x as the masses lap it up and are quite happy to spend vast sums replacing serviceable equipment with an 'upgrade' that has no real benefit [/I]

Or replacing knackered/broken if you've any sense - everything is a consumable on an MTB.

Just put 1x11 on my HT (was 3x9), only thing 'wasted' that wasn't knackered were the shifters, and reused the cranks of course.
