Review: NX Eagle - SRAM's New Affordable 12-Speed Drivetrain

Jun 14, 2018
by Daniel Sapp  



Many riders were stoked when SRAM launched their 12-speed GX Eagle drivetrain last year. It offered a high level of performance at a more affordable price than its XX1 and X01 Eagle siblings. Now, that technology is available at the NX level with an even lower price tag.

SRAM also moves away from the XD driver body for NX, with the 12-speed cassette mating with a standard 8, 9, 10 speed splined SRAM or Shimano driver body - which will further increase compatibility and allow upgrades to a 1x12 system without having to switch drivers.
SRAM NX Eagle Details
• 1x, 12-speed drivetrain
• 11-50 tooth cassette
• 8, 9, 10 speed splined driver body compatible
• DUB BB compatible
• Weight: 2049 grams
• Price: $375 USD
• Available: September 2018
www.sram.com

GX Eagle was half the price of the XX1 Eagle and had similar performance. Priced at only $375 USD, (shifter, derailleur, cassette, cranks, chainring, and chain), the new NX Eagle system is even easier on the wallet and it still performs incredibly well. It does come with a weight increase 202 grams, but the functionality of the group will be difficult to tell apart. The big story with NX is the cassette. Rather than requiring an XD driver body, it mounts on the tried and true splined drivers common to SRAM and Shimano 10-speed freehubs, which are a lot more common and also less expensive. That's good news for companies trying to pack even more value into their entry- to mid-level bikes - this gruppo will likely be a common sight on bikes in that price bracket for 2019.

NX Eagle is compatible with all SRAM 12-speed Eagle drivetrains (meaning you can mix and match parts). More compatibility is always better in my mind, especially when you've already emptied your piggy bank on gas and ramen to get to your summer riding destination, then inevitably crash and damage part of your drivetrain on your first day there.


There are a lot of similarities in the NX Eagle drivetrain with GX Eagle but, the cassette is a different story.


All New Cassette

The big change for NX Eagle is the splined-driver-style cassette. The XD driver that SRAM has been using for the last several years works well and is great in terms of making a lightweight system with a wide range of gears. However, when it comes to compatibility across wheelsets, for those looking to switch from a lower end drivetrain, or anyone already using a splined driver body, the associated costs to switch to the XD driver can add up quickly. If you are lucky, you'll just need to buy a new driver body, but a lot of hubs don't have that option, so you would be looking at a new wheel or wheel-set in addition to the drivetrain, making what was at first a somewhat affordable GX Eagle upgrade quickly double in price.

The new NX Eagle cassette mates right up to an 8/9/10 speed splined freehub, so you can't have that ten tooth cassette cog. NX cassettes begin with an 11-tooth, sacrificing a tiny amount of gear range. Some people may want to pick this apart as a negative, but really, most aren't going to notice a difference and if you do, you can always use a larger chainring.

The 11 by 50 tooth cassette mounts on a standard splined driver body.


The cassette is made out of 12 stamped steel cogs. The largest four gears are bound together with stainless steel pins and then the rest of the cogs slide onto the freehub body individually. There's a normal lock-ring holding everything together, and as a side note, the NX cassette is also the only Eagle cassette designed to be strong enough to use on E-Bikes. The 50-tooth bail-out gear, as some call it, could actually bail you out if you run out of power on a big e-xcursion. The NX Eagle cassette weighs 615 grams and retails for $100 USD - yes, it's heftier than GX by 167 grams, but it's also $95 less.

Cranks

The NX Eagle crankarms are 6000 series forged aluminum. They are designed to be used with SRAM's X-SYNC 2 chainrings and interface with SRAM's DUB bottom bracket system. They're available in 165mm, 170mm, and 175mm lengths and come with a 32 tooth steel chainring for $105 USD.

Shifter, Derailleur, and Chain

The NX Eagle shifter, derailleur, and chain are very similar to the GX versions. There are no major changes between the two groups, and NX shares all
of the same features, benefits, and technologies as GX. The biggest difference is NX components are manufactured from more affordable materials and weigh a bit more. The shifter sells for $42, the derailleur for $107, and the chain for $26 USD.

The shifter is no frills, but still it's still Matchmaker compatible and it functioned flawlessly.


Performance

I have been riding the NX Eagle group for almost two months at this point. A lot of that time has been in rain and mud, optimal conditions for accelerating wear on a drivetrain, and I have zero complaints with the NX group. Comparing it to the GX group that I had been running on the same bike for a few months prior, the shifting and overall performance are nearly impossible to tell apart.

bigquotesI really can't find anything to pick apart in this drivetrain. It simply works and works well.

The shifter is smooth and firm in its action. The large paddle tends to be the first piece to loosen up on any shifter as it wears, especially on more budget oriented models, but the NX has stayed firm and there's no play in it to date. Although it lacks the adjustability of the higher end XX1 and X01 models, it's comfortable and by no means feels "cheap" as some other more affordable shifters do.

I have not dropped or broken a chain, and despite the poor conditions I've ridden in, the drivetrain is as quiet as any other Eagle group in those same elements. From the small cog to the 50-tooth bail-out gear, everything is smooth, quiet, and crisp both up and down. I am starting to notice some wear on the finish of the cassette in my more commonly used gears, as to be expected, but performance has not degraded in any way.

I really can't find anything to pick apart in this drivetrain. It simply works and works well, at that. Yes, it's heavier, and maybe a little clunkier than XX1 or X01 Eagle, but you can also buy the entire drivetrain for less than what a XX1 cassette costs. As far as practicality and ease of use, it's exactly what it should be.


Pinkbike's Take:
bigquotesSRAM offering a 12 speed 1x drivetrain that doesn't necessitate an upgrade to an XD driver from your existing splined freehub may not be a step forward in technology, but it will be a huge move in terms of practicality for a lot of riders. The NX Eagle drivetrain is going to be the "go-to" for a lot of riders looking for an affordable and reliable 1x set up. Daniel Sapp

 Only PInkbike can think a ridiculously heavy 615 grams cassette with redundant gears is an improvement.

You really do not need 12 speed if you are getting a cog spread such as this one: 11-13-15-17-19-22-25-28-32-36-42-50. In increments that is a rather ridiculous 2-2-2-2-3-3-3-4-4-6-8: completely redundant first 5 gears AND a huge gap on top ...

 So is that mean that drivetrain will fit my shimano freehub? And I'll get 11-50 range for 375usd without changing my freehub?

 @duzzi: You cant look at teeth gap by number of teeth between cogs, you must look at teeth change.

11-13t = 18% difference
42-50t = 19% difference

So the first gap of 2t is almost equal to the last gap of 8t.

 When developing this group, was SRAM aware Shimano was in the process of switching to a new freehub interface? Sure it may not be common to mount a NX cassette on an XTR rearhub. But in two years you'd expect these on the SLX hubs too, while they probably want to keep this NX group unchanged for a little longer.

This may be the first time I expect to hear SRAM moaning about changing standards...

 @WasatchEnduro: Only the SRAM commercial that is going on on this page can think that this particular 12 speed gets you anything in respect to a better spaced 11. I'd take a better spaced eleven speed , e.g. 11-13-15-19-22-26-30-34-39-44-50, any day.

You do not need 12 speed with a 11-50, i.e. 454% range ... all you are getting with this cassette is 5 redundant low gears, the corresponding need for extra shifts, and an overdrive. Not to mention that at 615 grams this is heavier than any conceivable dual set up (and offers much worse gearing) ... it is ridiculous.

 @vinay: there are a lot of us on here but we are always afraid to speak up. I do floss my cassettes once in a while, but I haven’t really compared to see if that leads to longer lifespan? Ive had great luck with rf and wolftooth chainrings...

 @derekr: anyone with strong legs will damage a freehub body that's aluminium or titanium. I hate multi-piece steel cassettes because my main wheelsets/bikes are aluminum (2x King) and titanium (1x Hadley) so there's no way I would risk thrashing another freehub body to run a "cheap" 12spd Eagle NX cassette.

And sadly, the XD parts to swap those hubs quickly turn THAT conversion into a $500-$600 process with a new cassette. FML!

 @WasatchEnduro: There are a few of us that may recall the Suntour vs. Shimano days, where riders (even before the dawn of bitching and foot stomping on the internet) argued the merits of Microdrive (compact cassette) , Suntour's freehub design and compatibility, and the dawn of 8 speed. Shimano won (shift ramps ftw), but all the peanut-gallery pontificating is no different than almost 25 years ago.

 @duzzi: Look, you can argue that you don't need any more than one gear. Hell, you can argue you don't even need a bike since running is free and it still gets you from place to place. 12-speed is not critical to enjoy your bike, true, but if someone thinks it may help them enjoy their bike to the extent of shelling out about $400 for it, who are you to shit on that?

On the subject of teeth changes: they could make every gap the same over an 11-50 spread if they did 11 12.6 14.5 16.6 19.1 21.9 25.1 28.8 33.1 37.9 43.5 50 but you can't do a fractional tooth so tough cookies. If you're going to gripe, do the math right and complain about 2 through 5 being a little off. And even then, SRAM has decades of R&D plus real-world testing and feedback which has likely led them to some very compelling reasons to lengthen the gap between the lower gears.

 @vr6ix: my Sunrace 11-46 11spd cassette has the 7 or 8 (or 9?) largest cogs pinned to 2 aluminum carriers, basically eliminates notching aluminum freehubs. The remaining few loose cogs don't get much torque on them.

 @wibblywobbly: No matter how much you paid that lady, I don't really care what she saw in her crystal ball. Except for some German brands like Cube etc, it is not common to spec OEM hubs that actually say SLX or Deore on them. XT or XTR, yes that's fancy. But below that, companies like Kona etc do spec these lower end Shimano hubs but as "non-series". That is, with the name Shimano and a type number (and often also the option to have six bolt IS brake rotors), but not as part of a particular series. Which is fine. Technically it still makes it equivalent to SLX or Deore. I know Shimano hubs don't get much love here, but I believe they're incredible value. I can get an XT hub with a steel freehub body. Or I can get a Hope hub and pay more for a separate steel freewheel body than I'd pay for an entire XT hub. Sure, I understand the PB crowd is too clumsy to operate a chain whip or handle a spanner to service cup and cone bearings. Fork service, pressing bearings in and out of frames and linkages? No big deal. But cup and cone bearings. Oh no! Rather neglect them and then complain about their durability. But see, below a certain pricepoint (or at least when setting priorities), there is no way anyone can deliver hubs with cartridge bearings that are the same price and quality as Deore or SLX Shimano hubs. And people buying at that pricepoint aren't going to replace cartridge bearings when they can get cheap cone spanners, bearing grease and generic 1/4" balls at the shop round the corner. Tools are cheap, parts are cheap and skill is free (or you make new friend learning or teaching those skills for the price of some tea and cookies).

But you know what? Come back in two years and try to prove me wrong. Good luck!

They are absolutley rock solid and cheap as hell AND they don’t even weigh that much, especially if you factor in a proper steel freehub body on those anodised cheese hubs that Hope somehow fooled everyone into thinking are the shit (of course they are actually just shit). But I’m not surprised, SRAM proves the fact that marketing beats product quality by their very existence and mtb is now a fashion show first and foremost. Who could possibly been seen on the trails with cup and cone hubs? Somebody who is more concerned with riding time than how many approving nods they get outside the cake shop perhaps.

 I’ve not actually counted but I’ve got what I think is a 10-46 SRAM cassette with a 32 tooth chainring on both of my bikes and i rarely use the top two cogs because my bike ether starts wheel spinning or trying to wheelie in those gears. Surely a bigger cassette will only make this worse?
  • + 5
 @thenotoriousmic: For relatively flat XC riding this is true, but the bigger gears come into their own for big-mountain style riding where you may want to save your energy while climbing continuous 8 - 15 % grade for 2 or 3 hours to best enjoy the descent. These drivetrains are ideal for big travel trailbikes where sitting and spinning is the only way to get the heavier/squishy bike to the top. Sitting and spinning is also much easier on the knees.

 @thenotoriousmic: what it allows you to do is run a 10/11-50 cassette and go bigger at the front, for bottom end, I upgraded from 42t max at the rear to 46t and was able to step up to a 34, and possibly in the future a 36t chainring and gain a tonne of range on the fast bits.

 @moose-tastes-good
Yeah, sure.
If you like to put 615 g (!) of poorly engineered 11-50s unsprung rotational weight to your rear wheel, it's up to you...
For that same price you can get a very well engineered and durable XT 11-46 11s cassette which is 120g less...
And if you really think the 4 t difference on the larger cog worth the 120g difference at this precise location (unsprung rotational weight), you make a big mistake...

This doesn't exclude NX eagle being nice - hyperglide stuff is literally everywhere and not going anywhere except for high end mtb. think of all the bikes out there with blown out drivetrains that will get NX on there, plus lower-end oem.

for beginner riders / budget where "more gears = better" (and more range actually maybe is better for them) they'll get 1x 12sp. and they can buy XD freehub or wheelset later if they want. this will be shwoing up on $1200 hardtails soon.

 @reverend27: Shimano said as for now only DT Swiss has access to the Micro Spline freehub body design and they aren't thinking about licencing it to others for the time being. My bet is an exclusive deal with DT for about a year or untill 12 speed XT releases. Most OEMs are using DT hubs anyways on theyr kits that are in the XTR price range which will probably be the bulk of the sales of the new XTR at least in the beginning.
  • + 1
 @filmdrew: I've stuck with Shimano for this very reason. I've got a wheelset with DT440 hubs too and the cassette ate into the body, pretty annoying to get it off. But I also heard DT rims of that era used to be of soft alloy (indeed, having their 6.1D rim) so I thought maybe that also goes for their hub. I recently went with a Syntace wheelset for my latest build, which actually does have an aluminium freehub body. We'll see how this goes. If it does give issues, I'll get their replacement body with three steel splines. Should be just enough to keep it in check. I considered Hope too, but both their hubs and then the steel body seemed quite expensive. I don't care much about the weight either.

Why is the consumer on the hook for solving the problem? What’s so holy about the freehub body anyways? We’ve changed everything else.
  • + 2
 @speed10: it was originally designed by Shimano to be a steel free hub body, it's not their fault that most hub manufacturers ignore that in the chase of dropping more weight.

 1150 11 speed cassettes have been on the market for close to two years. The range of a 1150, 454%, is not much larger than the original 11 speed 1042 that has 420%. Both are very far from SRAM 1050, at 500% and Shimano 1051 at 510%.
  • + 2
 @duzzi: depends how you calculate it. I dont think its 'very far' from the Sram 50t and Shimano 51t at all. The 10t is 10% different from the 11t, and that is the only gear you are truly missing.

Practically speaking, I can't recall when I last needed the 11t or even 13t on my bike, so having the 10t is definitely a luxury more than a necessity.
  • + 0
 @ronufoh: not many ways to compute it ... it is the ratio of largest to smallest cog ... But the point is that if 420-450% range is all you need, then you REALLY do not need 12 gears (especially when they are so badly spaced). Add another 50-60% range and then an additional gear is nice.

Besides the 1051 Shimano introduced two 1045 (450%) cassettes for 2019 with the option of either 12 speeds (for cross-country racing) OR 11 speed. 12 speed 1150 for general use is just silly ...
  • + 2
 @duzzi: agreed on your point of 12 speeds to cover 11-50. I think I just worded my point poorly. But not fair for you to say the 11-50 range of 34% greater than 10-42 is 'not much larger', but 46% less than 10-50 is 'very far' off.

Once again practically speaking comparing the SRAM 10-50 with Shimano 10-51, the extra 10% range (huge or not) works out to 1 tooth at the extreme low end, basically inperceivable.

I really wonder why SRAM didn't offer a 10-46 11spd cassette.. That would give most riders ask they really need IMO

  • + 3
 @literally: My bad, I did the math from memory for the weight. The Sunrace cassette is still more rigid, since it relies on two spiders rather than having eight separate cogs as the NX one does. I listed the .de sites since that's where I see most of the US folks buying stuff cheap. Since I'm from Argentina, I usually grab my bits off eBay. I still maintain the Sunrace option would be best for the money, since it's better constructed.

Not throwing dirt on SRAM though. They have their way to do their cassettes, and I'm actually using a mix of X1/GX 11sp drivetrain on my bike, just paired to a Sunrace 11-46 cassette because it has a splined interface as my rear hub, greater total range than the SRAM available options, and better gear spacing than the Shimano ones. It doesn't have to be your cup of tea.

To everyone saying Shimano is way behind what about SLX 11speed 11-46t, it's been out for ages, is just as good value (if not better) has a shadow mech that wont get wiped out by every rock, is just as compatible and the cassette is 150g lighter (which is a big deal for un-sprung mass)
Once you forget about the 12 speed hype the marketing teams tell you you need its the smart option (XTR still has an 11 speed option because the pros didn't want 12) if you really need those extra 4 teeth at the top then go Eagle but in the real world i doubt many will care between 46 and 50t.

An SLX build 11spd, with an 11-46t rear cluster will set you back less money than this, but paired with a 30t front chainring, will deliver similar gearing inches.
Weightwise, the Shimano group comes in at about 150 grams less weight.
Honestly, what is the advantage of 12 over 11 speeds, apart from the one gear?
Is it worth 150 grams?

 Would not have this given, SRAM Eagle has been the worst product I’ve ever put on my bike. Managed to rip off 6 mechs (4 X01 and 2 GX) countless chain snaps, and 2 bent chains. All this in the space of 6 months. These mechs didn’t have a scratch on either so don’t say I hit a rock. It’s a known fault by SRAM that they have kept hidden, some of you may of noticed that they have started providing rear mechs with little ridges on the jockey wheels. this supposedly fixed the problem of the chain slipping into the space between the jockey wheel and cage but still managed to mangle a one week old X01 mech with the new “improved” jockey wheel. Utter rubbish, had friends have exactly the same problems too, riding Shimano XT now and not a single issue.

I highly doubt most users are actually making full use of the range too.

 I'm not sure if it's a quality issue or bad luck but my GX derailleur blew up within a couple months of riding. Not sure if it was bad luck or a particularly gruesome insult to it. I'm still not sure what happened: fairly innocuous section of downhill trail and no precipitating shift or crank through on a shift-loud click- weird feel- no jockey wheels and bent to hell. I came from an xtr system that ran flawless for 2 years and an xt that ran flawless for 4 years before that. Maybe just a strange event and I peeled an errant twig through it at an uncommon angle but still was not impressed that the thing ended up f*$kered beyond repair so rapidly. Hurray for zip ties to bodge things single speed to get me out and still have a decent ride! Any one lese had similar issues? If so- I certainly wouldn't want to take a step down in quality from that one. I replaced mine with an X0 which is running well thus far.

I still dont know if it is the derailleur perhaps? the first cassette had probably 600 miles, the second on may be 100; now is running super smooth. This new NX 12 speed is going to take a huge part of Shinamo business, just hope is not spec in 5k bikes. I think shinamo took to long on releasing their 12 speed. Is 12 speed necessary? no.

BUT: 615g at the rear axle!? seriously? I am no weight weenie, but 170g more and significantly less range than the "real" Eagle for some 10 bucks less than GX? Lighter, probably cheaper depending on the cassette, to be honest I´d rather run shimano SLX with the 11-46 or 11-50 Sunrace/Garbaruk cassettes. Also (I know, I know anecdotes are no evidence) but out of the 4 people I regularly ride with who own SRAM stuff, on ALL of them the thing the B-Tension screw pushes against broke away. LBS told us "happens all the time". Fix it? Well buy a new RD.

Anyways, I really like sram stuff for the most part. And this makes total sense business-wise. But I´m not really excited about it. Rather get the xd driver and go GX, atleast for the cassette.

 @daweil: $10 less?! Please, link me where to get a brand new complete GX Eagle drivetrain (including cranks/chainring) for $385 USD. This is the complete NX; the only GX groups I've seen in your stated price range excluded the cranks and chainring, sometimes more.

 @mtbikeaddict: I´m writing about the cassette alone. And okay I exaggerated, I think the difference is like 20€ depending on the shop, and nx will likely drop more with street pricing.

 LOL, i'm using a sram 10-speed 11-36t XG-1099 cassette I got on pinkbike for $60, ONLY WEIGHS 202 GRAMS!!! Uses the same tech as the eagle cassette, its machined out of a solid block. All other components in my drivetrain are shimano XTR 10-speed and I can tell you my bike shifts as good as it gets. Why in the world would somebody want to add another pound for 50t, I feel thats just overkill but I guess it really depends on your terrain. I like Shimano and Sram equally but I need to be honest and say Shimano has the better deals on the drivetrain, so hard to beat SLX 11-46T groupset, dirt cheap too. This Sram NX groupset seems pretty nice but just too heavy for my liking

 I reckon Shimano will release a legacy 11-51t cassette as well as a 10-51t with XT. To be fair, with XTR, there's no need for a cheaper hub option. It's not supposed to be cheap.
  • + 2
 This is big deal, particularly for any riders that were still running 2x drive trains. Once you take off the front derailure and the second ring the weight difference is pretty much zero and you get to simplify your system and run the most up to date drive train. All for less than $400. Pretty awesome. These are the type of developments and releases that probably aren’t huge money makers in and of themselves for companies but have a big impact in creating the impression that the company is rider focused, and is decoupling products for average joes just as much for wold cup competitors.

I hope when Shimano finally does SLX 12 speed, it I'll be 11 to 51, fitting on a standard hub and cheaper, more reliable, and better quality than NX, or with10 to 51 with Shimano driver to compete against GX. Lets see? In the mean time wonder what new Eagle replacement will be? Maybe the advantages 30t clearance and 8 to 46 makes more sense for MTB?

 I was the first one to doubt about the performance of gx eagle but after close to 1500km in 7 months, I am really amazed how well it works.
I sadly ripped the derailleur apart when a branch made contact with it but it has been replaced since (the gx eagle derailleurs are still hard to source in canada as far as availability goes). The new derailleur has a really crisp feel and just feels so smooth. My only gripe would be the quality of the pulley wheels. After a rough autumn and the occasional spring muddy ride, one of the pulleys almost seized even though I cleaned and regreased them. The derailleur has a bit of side-to-side play but you can't feel it on a trail.
  • + 2
 I’m not a weight snob by any stretch, but it wasn’t until I double checked the difference between my XT 10spd cassette and this one. 309g vs 615g... even a Sunrace 11-50 comes in at 586g. A savings of 30g

 I'd rather have 2x8 at this point. 38/22t chainrings and 11-32t cassette. Lighter, stronger, more reliable, better gear ratios. Bet you could release it as the next big thing and charge out the nose for it.
  • + 2
 Exactly. If price is all that matters this is a great product, but I'd rather not add over a half pound to the rear of my bike with the cassette alone compared to X01 or even an E13. I thought the XT cassette was heavy!

www.cyclingnews.com/news/tour-de-suisse-bike-mechanical-costs-christian-a-shot-at-stage-victory

Dropping the chain can happen on a traditional drivetrain with a front derailleur, and Christian's mechanical could be down to a number of factors - low clutch tension, a slightly too-long chain, the lack of a chain guide and a number of other reasons could all be to fault.

However, a rattling from the rear derailleur at the finish line suggests low clutch tension, or a failed clutch system, could have been the cause of the dropped chain and the reason Christian lost time.

 Have you had your daily dose of fanboi juice? OK, not let's talk seriously. Shimano and SRAM have had very different approaches to the drivetrain market ever since SRAM accepted they couldn't make a decent front derailleur. That ended up paying big for them, and Shimano had to give in and start making oneby groupsets. OTOH, Shimano chooses to release their innovations and propagate them top to bottom, while SRAM focuses on the OEM market.

 SRAM is out for the masses, it seems. Everyone is barking at Shimano for releasing a proprietary freewheel body with XTR whereas it was SRAM who initially made the blunder. Now SRAM is smart enough to keep NX compatible with Shimano, which leads me to think that SRAM is not after the shallow pocket working class mountain bikers but instead, are out to do some damage to Shimano's customer base. Excellent tactics so far as i am concerned.

 @TheRaven: let’s be honest. They both have their duds. But Shimano has been coasting off this aura of reliability for years. XT Brakes are just as bad as Elixers were back in the day. Eagle derailleur are exposed and sensitive to gusts of wind. Everything that isn’t XTR is made in a Laotian sweatshop with zero QC. Shimano derailleur clutches have a four month lifespan. The reverb...

But overall, Shimano’s lack of innovation and engineering excellence is ignored in favor of positive brand image from 8 years ago from when they were the best.
  • + 2
 @wibblywobbly: I was being honest. They do both have their duds. Shimano's duds still work. There's been no coasting. XT brakes are the benchmark against which all others are judged...comparing them to Elixirs? What are you smoking? SRAM clutches don't last...i've never had to replace a Shimano clutch.

Lack of innovation and engineering excellence? LOL...when XT is more durable and more reliable than XX1 despite being cheaper than GX? I guess you'll see what you want to see...but you gotta be smoking some quality stuff to really believe this.

 @TheRaven: you obviously have your point of view and I have mine. Are you like a Shimano rep or something? You seem awfully invested in them. All I’ll say is I’ve ridden enough bikes and spent enough money to have a real opinion, no a regurgitation of forum talking points from eight years ago when Shimano was the unquestioned king. I’m under no illusions that SRAM is perfect. The sad thing is Shimano with all their resources could be so much better than what they are.
  • + 8
 @wibblywobbly: I'm just a 19-year rider with lots of wrenching experience. I go by nothing but my experience and the experience of the riders I know personally. Yeah i'm definitely partial to Shimano...but that comes from my nearly two-decades of experience. You ride something for long enough and have almost no issues whatsoever, and then try out the new-kid and immediately start having problems, logic dictates how you will react to that.

The sad thing is that there's no objective reason to say that Shimano isn't already fantastic. You can say you like SRAM better for personal reasons but to say Shimano could be "so much better"...i'd love to hear some objectivity as to how. They already make the best brakes in the business, and when they launch their drivetrains they are properly developed and tested...unlike the miscues and recalls that happen with every single SRAM launch. As you said both brands have their duds, but Shimano's "duds" are dumb ideas with excellent craftsmanship and quality (like dual-control, or 40t 1x cassettes, for instance) whereas SRAMs "duds" are poorly designed AND poorly executed (like the Reverb, or all Avid/Elixir brakes for instance).

Their respective mottos are painfully obvious: SRAM - get it out first and make it look good, Shimano - get it out right and make it last.

 @wibblywobbly: Wibbly, honest question - assessment of effort level by Shimano on the new XTR?
  • + 0
 @mm732: three years late. They needed to be coming out with SLX 12 right now. Their big advantage is Di2 and that is another year out. And they seem to be sticking with wires.

The new hub is interesting, but the engagement isn't anything special and the way they are rolling it out to the market may make it dead on arrival.

They need to do a better job of marketing the alloy cranks and telling me why they are better than carbon because it seems like a company stuck in their ways rather than innovating. Same with the bearings in the hubs.

And for being the "masters of metal" they still can't match the way SRAM machines their cassettes.

Want to believe the brakes are fixed, but they will have to prove it to me.

Shimano is big enough right now that they can push back against the future. Right now they are playing catch up by hitting infield singles.

 @TheRaven: I'm sorry but the current gen Shimano brakes are not the best in the business.They just aren't. They aren't even as good as the previous generation.

what was the miscues that happened with the Eagle launch? It's hard to adjust and set up right?
  • + 3
 @wibblywobbly: Shimano is not late simply because SRAM released it first. I assert that SRAM was early...a point I can back up with the quality issues and fixes SRAM has had to release to fix their early product.

Better job of marketing their alloy cranks? The ones that are just as light, while being cheaper and more durable than SRAMs carbon equivalents? You don't need marketing when the product speaks for itself.

SRAM's cassette machining? Huh? You mean their $400-500 cassettes? Show me a $400-500 Shimano cassette and we'll take a look at the machining.

Current Shimano brakes are the benchmark against which all others are judged. Go ahead, start a poll...Shimano wins with Hope in second. Hope makes great brakes and you could argue they are just as good as Shimano, but they are also double the price.

As for Eagle miscues- just Google "SRAM Eagle pulley issue".
