[Closed] Next gen XTR

Plenty.

It will save them .2 seconds on the trail centre climb

[i] I wonder if in real terms who will buy and use such pieces of kit[/i]

Lots of people. People said the same about front suspension, rear suspension, disc brakes, etc, etc.

If I win the lottery - I might stick it on my race bike!

Without winning the lottery - I'll remain mechanical while rear mechs cost more than my monthly rent! (student house)

EDIT - looking at the price of mechanical XTR I will also likely have to stick to XT and below 😥

I don't know, thats a helluvalot for a rear mech, i very rarely see bikes with xtr on now (i am sure someone will correct me here). Maybe when trickle down gets to xt we may see more of an impact.

The carbon cage is probably responsible for a lot of that, for the replacement market plus cost differential over XT has meant that whereas I always bought XTR, now I buy XT.

I like the idea of wireless (cableless at any rate) shifting, not having to maintain bowden cables and set up a front mech wouldn't be missed.

However I won't lose any sleep thinking about when it'll come down to SLX/XT level. It's in the "nice to have" category, along with carbon rims, electronic suspension and a body weight of less than 70kg.

Makes a whizzy noise. That's enough for me.

Although, re: Di2, this is pretty cool:

In the real world, the battery would never be charged.

Yeah - we were discussing this in the shop a couple of weeks ago and wondering if would make sense on a 2x11 setup to have the front mech change automatically, in conjunction with the rear, when you got half-way through the cassette. So, you'd have no cross-chaining and you'd always have a better chainline (maybe improving chain life).

£450 road mechs are fine, you're unlikely to bash them off a rock and send them into the spokes.

Don't see much advantage in electronic shifting offroad - at least not until you can ditch the cabling and have wireless.

Simple answer is yes, it's already been done.

I kind of think that 1x will be great on Di2 in that it means one fewer expensive shifter and mech. Maybe 1x12 XTR Di2 with a 10-50 cassette soon 🙂

druid/scotroutes: Shifting when you're not expecting it? I'm sure that won't cause any problems.

I'm having a save up for new xtr di. Partly I'm a tart partly shagged thumb and as much as I love grip shift on my bikes
I just can't get on with it on my big bike and it will fix the odd ghost shift I get now and then

I'm a DI2 convert... riding cables just seems,pretty crap in comparison.
I guess I'll just have to save.

Singlespeeding sounds so lame in comparison. And so right at the same time.

Nah. It would only shift when you wanted to... imagine going from the 5th to 6th smallest ring on the cassette when you are in the big ring at the front. Di2 could downshift the front and upshift one or two at the rear accordingly. Make sense?

Erm....that'd be an unanticipated downshift at the front?

You good with a chain tool? 😛

It wouldn't be [i]un[/i]anticipated if that was normal behaviour though?

Akshully, thinking about it a bit more, that's basically what Alfines and Rohloffs do already, only it's all internal.

What about all the crap/water that would get into the electrics along with the endless bouncing dislodging soldered bits?

custimisation solves a problem that does not exist IMHO

might be nice if you were racing but for us biffers Pointless
Therefore it will be a massive success.

The thing with mountain bikes is.. rocks and treestumps and water and mud (and in my case falling off a fair bit too - lookout an off camber wet tree root at 45 degrees "aiiiieeee!"). I snagged my rear mech up 3 days ago and it went slightly out of skew till i pulled the branch wrapped round my casssete out and adjusted the cable tension a bit - No idea how you'd do that no a Di2 set up. and i'd forget to charge it

ooooh its on the new Cannondale Flash Black Inc model

i very rarely see bikes with xtr on now

I seem to recall Shimano making a statement that this was a deliberate marketing thing on their part, not a conincidence. They thought that the last 9s groupset was too mass market and that in their oppinion XT not XTR should be the pinacle for production bikes. Especialy as SRAM was bringing out X0 which was 2x the price of XTR. XTR was therefore engineered, priced and marketed at the very high end, e.g. the carbon cage is lighter, stiffer, more expensive and bling.

As for the OP, I like the idea of Di2 and I'm confident it would be significanlty beter than a mechanical system. But unlike a mech 9and indeed chain and cassette) on a road bike which is an investment in bling and performance, the same components on an MTB get trashed so that within a matter of weeks XT feels like SLX, and SLX feels like deore, and Deore just plods allong being Deore (which is good enough).

I definitely see a future for wireless 1x11
That's 2 batteries, 2 circuit boards and 1 motor instead of double the amount for 2x10/11.

I think I could live with this level of expense, faff (battery charging) and potential failure points.

The faff of charging batteries would def offset the faff of cleaning/replacing cables and adjusting indexing. I don't foresee many failures from water ingress - sealing for electronics is pretty damn good these days and the manufacturers will spend a lot of money getting this right so as not to have ridiculous amount of returned items.

Smashing mechs that cost 3 times the price of a standard one would be my major concern. Perhaps more inclined to run one on my XC bike which sees a lot less abuse than my big bike, and has had the same rear mech for donkeys years.

ooh - yay I can have rapid rise again!
(or something similar)

Watch Road Bike Party 2 making of

They basically submerge Dura Ace Di2 for the waterpark section and hope it'll be OK. It was fine.

Given the number of deep scratches on my XTR derrailleur, I'm not sure I could cope with one three times the price...

Hey - whatchaknow Al? New XTR features exactly the sequential shift mode I was referring to. Its like they read my mind.....

Does this mean that you could have 2 rings up front giving the huge range by some with only the one handlebar shifter where you select a higher or lower ratio and the electronics sorts out the rest? That I can see as a huge bonus.

I reckon the way forward is a singlespeed and an uber 22 speed elec piece of wizardry. Should then have every base covered for a bimble however the mood best takes you on a given day...
