New Shimano Deore XT groupset for 2012

By Richard Tyler, in Birmingham, UK | Thursday, Apr 14, 2011 1.01am

Mountain bikers can look forward to lower prices, sharper looks and more braking power as Shimano roll-out upgrades to their second-tier Deore XT groupset to mark its 30th birthday. In line with tradition, the new XT will inherit many of the changes introduced to XTR last year, but despite the updated technology, Shimano say we can expect the price of the complete groupset to drop by around 10 percent.

Plenty more for XT

Versatility seems to have been the word written across the blackboard in big, bold letters at the XT development lab. The groupset will offer a dazzling array of options designed to address the requirements of cross-country, trail, all-mountain and 'trekking' riders alike. The chain and cassette are two of a very short list of components that have escaped redesign – and that's only because they were updated last year when XT went 10-speed.

While Shimano continue to tout the benefits of a 3x10 setup, XT's position as a staple for the cross-country market has been acknowledged with the introduction of a two-ring crankset, with a 38-26T option for trail riders and 40-28T for racers. Less shifts means less work for the left-hand shift lever, but rather than complicate things with multiple lever options, the new XT lever features a mode converter for easy adaptation between three- and two-ring setups.

Braking will get a big boost, with the Ice Tech technology unveiled on XTR last year being passed down to its sibling. XT will benefit from the same striking cooling fins and one-way bleed system, as well as new rotors with the same stainless steel/aluminium/stainless steel construction. All-in-all, Shimano claim a 25 percent increase in braking power as well as vastly improved heat dissipation.  

The big S are also introducing dedicated XT-level 'trail' and 'race' wheelsets for 2012. The former has 21c tubeless-compatible anodised aluminium rims, with a 15mm E-thru hub up front and a choice of 12mm E-Thru or quick-release axle out back. The 'race' option has narrower 19c rims, with a quick-release rear hub and a choice of QR or E-Thru up front. All the wheels have cup-and-cone bearings, Center Lock disc mounts and 24 stainless steel spokes.

The new groupset will be offered in either silver or black. The latter will provide a good match for the new XT pedals which, as with XTR, include an integrated cage trail option (PD-M785) as well as a slimmer race version (PD-M780). Both have a much bigger surface contact area than the current M770 for improved stability, along with a slimmer axle housing for improved performance in mud.

  • Crankset: 42-32-24T triple, 38-26T double or 40-28T double
  • Rear derailleur: Improved Shadow design
  • Front derailleur: Angled adjustment screws and clamp bolt for easier fitting and maintenance; direct mount option
  • Chain: New 10-speed HG-X directional
  • Cassette: 11-36T, 11-34T or 11-32T (CS-M771-10)
  • Shifters: Rapidfire Plus with Vivid indexing (as on XTR); Instant, Multi- and 2-Way Release; mode converter allows use with double and triple cranksets
  • Brake levers: Lightweight, with Servo-Wave technology, free stroke adjuster and tool-less reach adjuster;  one-way bleeding system; Ispec compatible
  • Brake callipers: Compact, with oversized 22mm ceramic pistons and one-way bleeding system
  • Brake rotors: Ice Tech technology (aluminium core embedded in stainless steel) for improved heat management; 160/180/203mm with Center Lock or six-bolt mount
  • Brake pads: Optional Ice Tech pads with aluminium cooling fins
  • Pedals: Lightweight cross-country (PD-M780, 343g/pair) and integrated cage trail (PD-M785, 408g/pr) versions

The new XT will be available from July, with pricing TBC.

Shimano were showing off this bike kitted out with a complete 2012 deore xt groupset on the opening day of this year's sea otter classic:

Trick new bits for 'trekking'

Shimano have broadened XT's appeal by developing a series of components and features aimed at commuters and leisure cyclists, or in their terminology, 'trekking' cyclists. Durability and practicality is the aim of the game here, with full-length outer casings, hub dynamos and an integrated chain guard for the front end of the 10-speed drivetrain.

The trekking group comes with a choice of V-brakes or Servo Wave disc brakes with three-finger levers. The discs don't get the mountain bike brakes' cooling fins but they do come with Ice Tech rotors (160 or 180mm, Center Lock or six-bolt). Shimano claim a 14 percent increase in stopping power over the current equivalent – a considerable improvement for those weighed down by panniers and racks.

Black or silver, trekking or non-trekking - there are a dizzying array of options available for xt users to choose from: black or silver, trekking or non-trekking - there are a dizzying array of options available for xt users to choose from

The Hollowtech II crankset will be available in two versions: FC-T781 (48-36-26T or 44-32-24T; chain case compatible) and FC-T780 (48-36-26T: not chain case compatible). Both feature an integrated chain guard. Out back, there'll be a choice of 11-32T or 11-34T cassette.

Two new 6V-3.0W hub dynamos are available. DH-T785 is a disc brake version with Center Lock rotor mount, while DH-T780 has been designed for use with V-brakes. Both have an aluminium coil and axle, bringing weight down to a claimed 483g.

A 'trekking' variant of xt will also be available: a 'trekking' variant of xt will also be available

There's a new trekking pedal to go with the two XT mountain bike options – the double-sided (SPD binding on one side, flat on the other) PD-T780. Claimed weight is 392 g/pair, including integrated reflector. Like its mountain bike stablemate, the groupset will come in a choice of black or silver. Availability is slated for August 2011.

XTR Shadow Plus rear derailleur

At the launch of the new XT, Shimano also unveiled a new XTR M985 Shadow Plus rear mech. Designed to complement the 'trail' rather than 'race' variant of the group, it has an on/off switch on its cage which can be used to add more spring tension and activate a 'friction stabilizer'.

The idea is that you switch this on to stop your chain bouncing when riding over rough terrain – preventing it from derailing or damaging your drive-side chainstay, and also cutting noise – but flick it off at the end of your ride to reduce the spring tension and make it easier to remove your rear wheel. The new mech will be available from June. There's no word yet on pricing.

  • Sweet..!!

  • Why do Shimano insist on using cup and cone bearings in their hubs? I don't have the tools, skills, time or money to keep them running sweetly. The drop in price is very welcome though. Maybe Sram will do the same ?

  • Hucking Fell -

    Tools - 2 normal spanners, alot less than needed to service some sealed bearing hubs such as DT Swiss 240's or Hope

    Time - not much longer than sealed bearings really, more a bit of extra faff dealing with loose balls but prepare properly and its not a problem

    Money - loose ball bearings cost alot less than equivalent sealed bearings

    Skills - thats up to you isnt it, but its not a hard job. I was doing it when I was 12 and sealed bearing hubs didnt exist. I would suggest if it bothers you then you would do well to teach yourself. There is very little you can do wrong

  • It looks like an old Deore in black

  • I want that XTR mech...

  • @ iain1775

    Isnt it also the case that cups and cones offer lower rolling resistance and operate better than cartridge bearings for loads which aren't going straight up through the wheel? Much to my dismay I opened up my road hubs at the weekend to discover what had looked like cup and cones are in fact covers for cartridge bearings. Cartridge bearings in my opinion are a royal pain to service in comparison to cup and cone.

  • Oh dear!

    Traditional hubs need regular maintainance to prevent the wear/damage of the bearing races (and rendering the whole hub useless).

    They are also adjustment sensetive (slight play to compensate for clamping forces), so yes, they are certain things that can go wrong.

    Quality cartridge bearing hubs are fit and forget.

    You actually DON'T NEED to adjust or clean them but instead you ride you b****y ike.

    I haven't touched my Hope Pro's for ages. Still smooth with no play.

    If I eventually wear the bearings out, I'll put a new set and it'll be like new.

  • Price REDUCTION - Well that is news.

    Maybe the tide of higher and higher prices is finally turning.

  • cant knock shimano for function but they are left lacking in the aesthetics department. saint is a good looking groupset and the splashes of colour to the xtr trail bits are welcome but the rest of the range looks a little dull. also i would like shimano to machine the teeth on their outer rings like fsa and TA as it looks better longer and adds a touch of class. i do like the look of the brakes though.

  • what special tools for servicing hopes. all I need are my fingers to pull off the caps and to pull out the free hub. If I ever need to replace the bearings I would just need a soft rubber hammer and a 14mm socket to press in the new bearings. (which i haven't needed to do in 11 / 12 years. ) YUP same bearings in 11 years. just given the free hub body a clean out every 6 months.

  • And cartridge bearings are cheap to get . I can get any size bearings I need from a Motorbike shop down the road I can replace all my hope hub bearings for front (2) and back (4) for less than a £10 and they are Japanese Stainless steel . BOCA bearings are fantastically cheap too for how long they last .

  • i quite like the look of them. They have obviously recessed the graphics to avoid heel rub. Liking the fact that the brakes are XTR through and through in looks at least.

    It will remain to be seen what happens with the price when it gets handed down to us mere mortals though...

  • Why hydraulic disk brakes for a trekking groupset? On a trekking bike you want cable brakes, like Avid BB7. Hydraulic means too much maintenance and if it breaks on the road, you have a problem.

  • @ iain1775

    I've spent an hour or so "faffing" with a cup and cone bearing hub (Shimano Deore) just getting it not too tight and not too loose. The 1 time in 12 years that I've had to replace the bearings in my rear Hope Bulb took me less than half an hour.

    Cartridge bearings don't cost a lot. Letting the LBS sort the hub for me would cost a lot.

    But that's not a problem and I'm not "bothered" that I'm not well practiced at "faffing" with cup and cone bearing hubs 'cos I've no intention of ever buying any.

    I'm allowed not to like them you know.

    I have never experienced it, but then, I have only ever had one Hope hub and someone stole the whole bike...it was a superlight front ti front hub which weighed something like 70g. I am probably over-influenced by Sheldon Brown's site on this, the difference between forged and machined. But I have had axles break on me in the past, and I think axle strength is significant. Depends on how hard you ride your kit, whether or not it gives out on you, and you can only tell over time. For me, saving a few grams on a hub is less important than on the rim or more importantly, my fat *rs.

    I guess everyone has their own opinion on their kit...there is no right or wrong. I find adjusting the bearings on my Shimano hubs easy...I've never had to touch my XTR hubs and they run like silk. I didn't know I couldn't change the cups and would have to throw them away...but then I have never encountered a Shimano hub whose cups have worn through.

    I had a couple of wheelsets with cartridges, both of which have come with shoddy bearings in the beginning which seize...my latest set use a proprietary freehub which is going to be a pain to replace...hence my comments above, sorry that wasn't clear.

    Another bug bear with wheelsets is the skewers they come with...I find the Shimano ones to operate flawlessly. All the boutique skewers I have used have been inferior and overpriced...again, just a small sample of skewers over 20 years of riding.

  • i agree with barteos. cup and cone hubs are sensitive to adjustment thus, each servicing done on them makes the ride slightly inconsistent. i've had numerous cup and cone hubs/wheelsets and maintaining them is a pain in the behind. if you lose track of which to service next (my bad probably for having numerous bikes and wheelsets), you're bound to lose the hub entirely and replace it altogether. sealed bearings on the other hand don't need the extra attention. just replacing the bearings and off you go. and you don't lose the hubs if you forget to service them. also, performance is consistent all them time as long as you use the same type of bearings every time you replace them.

  • I am somewhat disappointed with this article - XT has been the mainstay of most riders offroad kit since the sport really took off and yet this is, at best, a brief comparison with XTR. Will there be a full write up?

  • Any idea what that white frame is on shimano display?..

    Cup and cone are pain in 0. Broke XTR axle and no spare parts. Just buy full new hub. Were extremely smooth running when working. Better than hope2 i have now.

  • When/Where can I actually buy the whole groupset.....
