Prototype Shimano Deore XT at Crankworx

Proto Shimano Deore XT

Jason Moeschler s Cannondale Jekyll

Jason Moeschler's Cannondale Jekyll at the Canadian round of the EWS had a proto Shimano XT crankset patched onto an 11-speed XTR drivetrain. His wheels were carbon protos by WTB, shod with massive Team-Issue 2.5-inch Breakout tires. The brakes appear to be stock 2014 XT with ICE rotors.



Shimano is famous for trickling down features from its premier XTR components to its second-tier offerings - especially Deore XT. The first XT component that we have seen so far which hints that Shimano might bring its 11-speed technology down was a prototype crankset on Jason Moeschler's Cannondale Jekyll. The crank arm has the same profile as this year's XT, with a slight exaggeration in the depressions near the base of the arm to afford bolt clearance where it lines up with the asymmetrical, four-bolt spider. The spider uses the same proprietary bolt pattern that Shimano debuted with its 2015 XTR crankset, one which doesn't match any popular BCD. Unlike XTR, the spider appears to be removable, or at least it is manufactured in two pieces. The 2014 XT crankset has a similar arrangement, as does SRAM XO, but while most SRAM spiders are interchangeable, the XT is permanently fixed to the crank arm and bottom bracket axle. An interchangeable spider would make the 2016 XT crankset far more versatile.

Hand made XT chairings and new XTR type spider 2015

The asymmetrical four-bolt spider of Jason's Shimano XT crankset is exactly like proprietary 2015 XTR pattern. The reddish tint on the, formed sheet-metal chainring could be evidence of rust, suggesting that it is paper-thin steel. XTR chainrings are crafted from aluminum and riveted to a thin ring of titanium teeth. The XT proto uses similar construction, but apparently, is built with alternative materials.



Jason's two-by crankset was shifted by a 2015 side-swing XTR front mech, but the star of the show was a prototype large chainring that resembles 2015 XTR. Hand-etched numbers on the sprocket clearly indicate that it is a one-off. Like Shimano's XTR big ring, the XT proto is a built-up composite, with a hollow base, fromed from metal sheet, that is riveted to a thin ring of sprocket teeth around the circumference. XTR chainrings have titanium teeth, but we suspect that an XT version would use steel or aluminum to better match XT's more affordable MSRP.

The fact that Jason was using a two-by drivetrain suggests that Shimano is digging in its heels on its notion that the combination of more closely spaced cassette cogs and two chainrings is the best solution for high performance mountain bike riding. The present popularity of one-by setups, however, indicates that Shimano will be facing an uphill battle if the coming XT group does not include a wide range option to compete with SRAM. That said, Shimano's ultimate goal may be to bring XT into compliance with XTR with the sole intention of readying its second-tier ensemble for Di2 electrification - which will nullify the one-by or two-by debate, as Di2 can command both derailleurs to sequentially shift through the gear range using only the right-side shift buttons. Consider that almost every EWS competitor who runs a one-by drivetrain also employs a crudely manufactured plastic front derailleur cage to keep the chain on - and Shimano's front mech presents a better looking - or at the least - an equally ugly alternative.

Shimano XTR 2015

The cassette appeared to be an off-the-shelf XTR 11-by-40-tooth, eleven-speed, which makes sense, considering that when production time arrives, Shimano could quickly craft an XT cassette using steel cogs instead of the wildly expensive titanium sprockets that grace the XTR version. The XTR logo of the rear changer was blacked out, but it appears to be un-altered. Jason did suggest that the chain was a new item for Shimano, which makes sense, as Shimano has a long-running fixation with micro-engineering chain profiles.


bigquotesShimano is famous for holding its cards closely to its chest, so we can only imagine what 2016 Deore XT will emerge as. What we can tell from the few pictures here, though, is that the great big engine that we call Shimano is steaming full speed ahead with a new XT ensemble, and that it will have eleven-speeds. Let's hope that somewhere in its 2016 offerings there will be a wider-ranged gearing option for a one-by XT drivetrain, but Shimano walks its own road, so we will have to wait and see. - RC




WTB's Carbon AM/Trail Wheels

Moeschler's Cannondale had two more surprises in store: a massively huge 2.5-inch WTB Breakout tire labeled, "team only," and deep-profile carbon rims that appeared to be production items. Considering how long that it takes to develop and test carbon wheels for a demanding application like enduro racing, WTB must have known all along that it was planning to release a carbon wheel while its marketing honches were busy shelling carbon in favor of aluminum last year when it released the KOM wheelset. We wonder how WTB will spin this one in the reverse direction.

The carbon profile looks to be about 45-millimeters deep and its outer width looks to be about 30-millimeters. A prominent decal that reads "C i24" strongly supports that theory, as most carbon rims have thicker flange widths than aluminum rims do. If true, WTB is staying put and ignoring the wider-is-better movement that is gaining popularity among vanguard wheel makers. WTB's business model depends heavily upon OEM sales, so it makes sense for them to produce rims that comply squarely with European ETRTO wheel and tire standards.

WTB carbon fiber rim

Did we say that aluminum was a better material for mountain bike rims? Oh, well, that was then and this is now. WTB's new carbon wheel was the only set to be seen at the Canadian round of the EWS, as all other WTB-sponsored riders were on aluminum 123 and KOM combinations. The new wheel has a deep profile and was laced with 32 spokes - an indicator that the rims is built to be lightweight. Using a larger number of spokes can better support the rim and thus, it can be make lighter without sacrificing strength.



WTB Breakout tire 2015

Check out the profile on this tire. WTB's 2.5-inch Breakout tire brings back the once-popular thousand-knobs tread pattern from the late 1990s. When used on a flexible casing and molded from a grippy rubber compound, the Breakout's low-profile tread configuration has proven to be a good, fast-rolling, dry-condition tire.

 When I'm ruler of the world, I will find every set of cranks with a proprietary BCD spider and all of the proprietary chainrings ever made, I will then have the secret police apprehend the designers and executives who thought they were a good idea. Then, I will have them all thrown in a pit and buried alive under their own stupid creations!

 WHAT IS SHIMANO DOING?

- ridiculous interpretation of 1x11
- assymetrical spider

I've been a big fan of Shimano for a long time. Their invention of external bottom brackets was great, and their disc brakes are the best deal on the market in my opinion. But there's no doubt my next bike will be stuffed with SRAM shifting if they don't come up with major improvements in their offerings. SRAM seems way ahead when it comes to shifting technology.
  • 9 12
 "SRAM seems way ahead when it comes to shifting technology." Indeed.
But when it comes to braking ?
How many bikes they come with Shimano brakes (not even Formula) even though they have Sram 'shifting' (i.e the new Nomad C).

 " Their invention of external bottom brackets was great"....yeah except now the bike industry is going to the press-fit shit-show standard.

 Everyone bitched about external bottom brackets when they came out. People installed them wrong, side loaded the bearings, and talked about the scam.

 As far as I own 10sp X0 and 10sp XT, it is the sram that is behind in shifting technology. 9sp sram was better but that was quite a long time ago.

 morale has selective blindness.

If SRAM and Shimano brakes had a baby, taking only the best attributes from each, it'd be Hope. Avid modulation, Shimano power, and a happy medium between the smooth initial feel of the Avid and the instant bite of the Shimanos.

I'll take my Shimano 2x10 over SRAM's 2x10, though. SRAM's X01/XX1 are a step up, IMO.

 The SRAM and Shimano brake baby you speak of is the new SRAM Guide. It's good, really good. My description of it is a Shimano/Avid crossbreed.

 I'll bet they're pretty good. I've had trouble with Avids in the past, so I get all the angst against them, but I came to really, really like my Trail X0s. Unfortunately, they don't pull park duty all that well (not that they're intended to), so I upgraded to the Hopes, which cost a pretty goddamn penny. Having had both XT's and X0 Trails, the Tech 3 E4 combo is the best brake out there, though I haven't tried the Guides.

 Hopefully the Guide turns out to be a great brake. Then manufacturers can spec a Pike, drivetrain and Reverb. The simplification will probably be good for business.

 SRAM started the "proprietary things" so their main rival started to do the same things. Customer wise, you should keep your loyal customer instead of try to sell 1 new item. In "crankin" things i guess race face did a great job with their new cinch system.

 Shimano has lost the battle, and is digging its own grave ... I wasn't a big SRAM fan until I've put on the X01 on my bike. And right now, the offering from Shimano is far from making me go back to Shimano. Reaaaaally far.

They really need to make a proper groupset to counter the XX1/X01/X1 from SRAM ...

 SRAM is killing me with not having an answer for double-tap upshifting. I'd be far more interested in their 11 speed if they had it. & that's coming from someone who's been on SRAM for 12+ years until last year.
  • 21 2
 I find the new XTR cranks pretty ugly.. And now these. Also, won't having asymmetrical spiders mean companies who make aftermarket chainrings have to spend money developing new products just for these cranks... or will they bother?
  • 4 1
 Shimano has had "asymmetrical" rings on their road group sets going on three years now... And guess what? Other manufacturers are copying it! Why? Because it's just as stiff/lighter than a 5-bolt due to mounting in relation to power point of pedal stroke.
  • 3 2
 The power point of the pedal stroke is a powerful pro in the list of pro/con points. The same should be done with bashguards (I rotated my old broken one, and it works fine still). l

 I can't remember thinking of how beautiful my cranks look when I'm pedaling up a 500 feet climb, cuz usually all i can think or do is to keep a good breeth rhythm and hope my lungs don't collapse before I make it to the top. Must be cool to have all this time to be concerned about fashion shit.
  • 1 0
 i hear yah about 5-bolt vs 4-bolt but as far as MTB goes, its always been the 4-bolt design coz of the lower tooth-count needed to crank mtb's. based on the picture, its still a 4-bolt pattern but not the stuff that were used to.
  • 11 0
 It's a great that Shimano brought out their own 11spd but isn't the point of super wide range cassettes to eliminate the front der. and go 1x11, kind of like when Sram brought out 10spd to compliment 2x10 and Shimano followed with 3x10 - rather pointless imo.
  • 11 1
 lets all be happy, just keep your old crank set, slap a NW and we have 1x11 for everyone
  • 10 3
 No, that's not the point. Shimano 2x11 gives even more range (on both ends) than SRAM 1x11! Nobody says you HAVE to run a certain configuration. That's the beauty of Shimanos 11spd... An XC racer can ride 1x11 race gearing and an older woman trail rider could run 2x11 if they wanted.
  • 6 1
 But if you want to run Shimano 1x11 you need a chain retention device. And everyone hates proprietary stuff, sure, someone will make narrow/wide rings for these cranks, but who wants to invest in it the first year?

I've run XT exclusively for over a decade now. I once bought a bike with X0 and swapped it out for XT. I hated SRAM shifting. No longer - I chose my 2015 Anthem SX because it has X01 and I'm loving it. And the range is very, very good.

Even from a purely marketing point of view SRAM has nailed it with their 1x system.
  • 9 3
 Jamminator, the old woman trail rider would still be served better by 1x than 2x. The 1x would be simpler to operate and she would just run a small chainring for easy going. She's not going to ride fast enough to need the second large ring. There is almost zero reasons to run a 2x setup, even with electric derailleurs. The big wigs at Shimano have lead the game so long they are in total denial they are getting beat. That's the only reason they are pushing this 2x crap... Denial.
  • 3 3
 "Simpler to operate"? How's that, exactly? DI2 is programmable to where you don't even have a front shifter! The rear shifter autoshifts the front derailleur in unison with the rear derailleur to always place the correct gear ratios in order. It's just as "simple" as a 1x setup from an operator/user perspective. And maintenance is no contest. DI2 has proven way more reliable over time with maintaining proper adjustments over basic cables. Truth is 1x isn't always favorable. Fabian Giger runs the 2x DI2 instead of the 1x because he can't get the range he wants. Almost all the Shimano sponsored XC woman run 2x too...because they don't have the power for a 1x. You're entitled to your opinion, but so are the consumers. If it's really not that great, consumers will decide with their wallet.

 Everyone may love Shimano brakes, but they seem to have fallen far behind in the drivetrain game lately. Sram's drivetrain offerings include AM/XC products with 10-42 cassette. Shimano's is 11-40, AND they still use a front mech. On the DH front, SRAM has finally realized that less is more, and that a closely spaced cassette is dumb for DH. Honestly, if someone comes out with a 5 speed cassette, I'll buy it for my DJ bike.

There you go, there have been proto parts doing the rounds for a year and a bit now, it looks great but Box evidently don't have the kind of money Shimano/SRAM can throw at rapid development. If the pricing on it is sensible (as in, competitive with XTR/X0 or cheaper) then I'll buy a set just to see if it's as good as it looks.

 Why Shimano did not stick to a 1x10 or a 2x10 system using a 11-40 or 10-40 cassette for regular freehubs with the Shadow derailleur? I don't like SRAM...not at all... But if I have to use proprietary chainrings for a XT or XTR crank, that may be a different story.

Please Shimano, put your act together before it's too late...

 Lets be honest, most like 1x because it cleans up the bike a bit, not because of better performance.

 It's a factor, but not having to deal with the finickyness of a front der is a big motivator for me, as is the improved chain retention. Front ders suck: even roadies use chain catchers on stages where they know they're going to be shifting the front a lot.

 At a guess I'd Shimano wants us to buy 2x11 because I'm sure they make more money if they can get us to by a front derailleur and a shifter to go with it.

 I don't have to look at it, but if the market offers a choice of products of comparable quality and performance, one would assume that a reputable brand like Shimano would offer some added value to stand out from the others, especially if it's their 2nd most expensive groupset and a technology they're introducing 2 years after their main competitor.

 I hate proprietary BCD as much as anyone else, and I sure hope the 11 spd chain works on standard 10spd chainrings cuz I'm not buying into a new chainring standard.

But I really can't understand the fetish for 1*11, does no one ride in the mountains anymore ? Or they stick to roads and "climbing" trails ? Don't tell me y'all are clearing uphill tech because I've seen many 1*11 guys who can sprint away from me on normal uphills (ie strong MF'ers) walking all the good stuff, especially on hour 4+. And then to boot, they can't stay at the front on a high speed road descent. So go ahead and love your range limited setups but no need to hate on the 2*X, because us mountain bikers still want and need them, and I'm happy Shimano is moving forward with it (although I agree they should have figured out 10-42 and then made it so you can run 1* or 2*).

 Yeah, I'm starting to think I may never see a refined gearbox bike in my lifetime. Shame. I think derailleur drive trains are the cash cow of the industry. The parts wear out and/or break so quick, and there is always a "better" one the next year. I bought a Rohloff in 1998 and I've not missed a shift, dropped a chain or had a drivetrain failure in 16 years. It makes derailleurs look like a sad joke.
