Shimano's mastery of design, materials, and the manufacturing process should be a blessing in the crowded dropper-post marketplace. Shimano's' late entry with the Pro Koryak dropper suggests that its engineering team was tasked to produce a truly reliable and durable mechanism, and I fully anticipate that they were successful. Otherwise, the only point of the exercise would be to remove SRAM's RockShox logo from high-end mountain bikes that were otherwise spec'ed with Shimano head to toe. The one glaring issue that I can see here, is that there is no 150-millimeter-stroke option - a faux pas that Shimano must rectify quickly, as long-stroke dropper posts are a must for today's fashionably steep seat tube angles. The take-away here, though, is that 120-millimeters is a good start and that Shimano's seamless ergonomics and mechanical ethos are sure to raise the score for a classroom populated by B-plus students. - RC |

Their products (the ones I've had anyways ) are quality and easy to maintain.
Had they announced a 150mm offering i would already have my name in the hat for replacing my expensive "works pretty good" when it does work #serviceandbleedfrequently reverb that came too short and stock with my bike before it offered 150mm in my diameter seat tube dropper post.
When Shimano offers the length I want the reviews (positive I suspect) will direct me to my local shop for purchase.
Let's see what gets done and how quick.
Is it a design flaw causing issues? Or is it a general thing to do with most folks preferences or something?
I for one am glad that SRAM, and competition in general are forcing the industry leaders like Shimano to innovate. Competition yields innovation and choice which is a win for the end user!
They have certainly made errors. Their first under bar shifters stunk. It had two thumb shifters too close together. Integrated shift and brake levers worked for some folks but the market spoke loud and clear and they dropped those.
You can always count on Shimano to be late, but they ALWAYS bring the goods. Sometimes they bring some extra crap that no one wants too, but they always take care of business when it comes to the core products.
I can't believe that I'm saying this, but at least SRAM releases components that people actually want. I'd much rather have the Guide brakes over XTRs, and i'd much rather run Eagle 12 speed over a 2x10 XTR group.
They have a 11-46 XT cassette and you can buy four of those for the price of one Eagle or six Sunrace 11-46.
I personally never had problem with the feel of Shimano brake levers and I just swapped the Guide RS to Saints that I had from last season because the Guides just didn't cut it for me on long descends.
But of course you ride whatever you prefer and can afford there is nothing wrong with that. If you are on the budget or just don't want to spend an arm and leg and you can live without the latest and greatest then Shimano is a good option. I have XO1, XT and SLX on my bikes and I don't have any problems with them.
"Would those hubs be attached to super narrow Shimano rims?"
Only if you want them to. If not, just buy the hub separate.
"Can I get a decent level hub with a six bolt pattern?"
Sure! See model number HB-M756/766/776/786.
"Would that reliable 1x11 setup be running a 11x40 cassette or do you have to modify it to give it a usable range?"
You can choose actually, 11-40, 11-42, or 11-46 factory, expandable up to 50t aftermarket. How many options does SRAM have?
"...but the last batch o brakes have been subpar. the days of Shimano brakes being the standard for reliability appear to be over. Plus, the servo-wave levers make their brakes feel horrible...nothing, nothing, nothing, nothing, oh god, everything is locked up."
By who's evaluation? Because you've seen some issue threads on the internet? I can tell you that the new brakes are just as reliable as the old brakes...they really haven't changed much. As for modulation - you have your choice. If you like the super hard on/off brakes (like most of the guys I ride with do), then you want the "Trail" style (XT M785, XTR M985/988, Saint M820). If, like me, you rank modulation over power, then you want the "race" style (SLX M675, XTR M987, Zee M640). Again, your choice.
"I can't believe that I'm saying this, but at least SRAM releases components that people actually want. I'd much rather have the Guide brakes over XTRs, and i'd much rather run Eagle 12 speed over a 2x10 XTR group."
Maybe SRAM releases components that YOU actually want. YOU have no idea what "people actually want". I'm sure you get your daily dose of MTB news on the internet, and reading through the comment sections you deduce that everyone is riding 1x11 with a Pike, X2, and Reverb. I can certainly see where you would get that impression. But that's not even remotely close to reality. 2x and 3x drivetrains still outsell 1x by several orders of magnitude. That being the case, Shimano has positioned itself best. It has 1x for the Enduro crowd and 2x/3x for the XC crowd (which is the bigger crowd by a lightyear). Maybe 1x is the future, but right now 2x and 3x are still selling like crazy, and we can't say for certain that 1x will ever be the standard across the board.
@packfill:
Sorry for bothering you both but I will ask you (maybe not only you but everyone who will read it) a question I've been interesting at for a long time. I ride cheap Shimano Olivio 1x8 transmission front - 36t narrow-wide chainring, rear - cassette 11t...32t. I have a all-mountain hardtail and I ride light street-trial (wheelie, bunnyhops) and all-mountain style on local trails... So sometimes I need to climb on a 35 degree (or even bigger) angle slopes (more than 200 meters long), and sometimes I need to ride 40 km/hour/25miles/hour (or even more) on a flat. So I have never had necessity to extend ranges of my transmission. Sometimes I think about increasing it's (transmission's) durability but ranges - never. So my question is what kind of style do you ride according to your needs of 400% ranges of your transmission? Thanks. And this is not a joke or some kind of a trolling it's just about I am starting to think that I ride in some kind of a strange way that I don't need stuff all the other people need.
My AM rig has a 32t N/W and an 11-42 cassette on 27.5 wheels, and it's JUST enough low end to handle the trails it sees...this bike doesn't generally see LONG climbs but it does see very short climbs that approach near vertical in spots (like a 5ft high rock that the trail rolls over)...and I need the gearing to be able to start from a dead stop on 45 degree or better slopes. On the other end however, the 32t-11t combination is more than sufficient as this bike rarely sees much in the way of real speed. So on my AM bike, the huge low end is for clearing very difficult obstacles.
My Trail rig has a 32t N/W and an 11-45 cassette on 29 wheels. This has worked well for the trails it sees. This is the bike that sees extended climbing on a regular basis. 20-30 degree grades for miles. Generally I will climb in the 36t or 40t, using the 45t only to clear large log and root hops, but i'm pretty sure i'd be walking if I didn't have that 45t.
It's not a matter of fitness in many cases, people ride very different trails and one guy's definition of steep is very different from another's. There are many places that just don't have the steepness, or maybe have the steepness but not the duration. I can tell you this, i've seen racers that run 50+ mile events end up on their 24/34 combo by the tops of a couple of the hills I ride (I can see that because i'm generally walking at that point). And then of course there are those who just need the range because they use one bike for everything - the low gear to clear the extremely technical obstacles and the high gear for the fireroads.
The real question is - why is this even a concern? Anyone who doesn't want to run a 400% range can simply run something smaller...and cheaper. Why sit here and complain it exists? If you can get away with an 11-34 cassette then that's awesome cause you save like $1000 on drivetrain. Doesn't sound like anything I would complain about.
making it easier with gears, is no different to having lighter bike ( i did a road event, 66 miles in the peak district, on a 30 pound + hybrid ) would of been back least 90 min quicker if i had a lighter bike, was murder on the climbs ( 6500 feet +)
but did enjoy the rowing machine!
even if it is in racing, you can get the bike below the weight limit very easily, and then add the weight back with the dropper
My brother and me have identical M sized Remedies and he has the 125 mm KS Lev and I have 150mm Reverb stealth. I'm 175 and he is around 180cm tall. There definitely is difference and we both agree that 150mm is way better than 125mm because as Kitejumping said, you can slam the seat down when going full on downhill and raise it back when going uphill/level. You just have more choice with a longer drop than a shorter one, and the longer one doesn't get in the way like a shorter does when things hairy.
I rode a 2016 E29 recently with a 125mm CP IRCC and it was bordering on uncomfortably high at full extension. Furthermore, I found my bike handling on descents to be significantly worse with the seat all the way down. I picked a middle setting and left it there for the entire ride. This is consistent with my other rides on demo bikes with droppers. I'm sure I would get used to it and eventually come to appreciate the dropper, but I just can't muster up enough enthusiasm to buy one yet.
So even if you have say too much of a drop (seat post is too low for some reason) when going downhill, Reverb at least gives you a drop limiter clamp so you can clamp it. Of course, pretty much all the droppers have "infinite adjustability" so most people don't need a clamp (I actually never saw anyone having it).
But I would still argue that the longer drop in general is better than having a shorter one. Of course, someone might need only 10cm of drop and don't want the weight of a longer dropper or similar. But if someone is say buying a dropper it is better to go with a longer one by default. Moreover, generally speaking, it is easier to make something longer shorter than something short longer.
Also having a post at the same height the whole ride kind of defeats the the purpose of the dropper post. Probably I'm misunderstanding something. The dropper post is something I would have a very very hard time adjusting to if I didn't have it. I use it absolutely all the time when I can.
Droppers are like forks, you can't just stick an extra long one on every bike. they're a fit item just like bars or stems. Since I have a fairly short (30") inseam, many bikes that fit me don't have enough exposed seatpost at a comfortable pedaling height to account for 125mm of stanchion plus the extra 20mm(or more) of seal head.
I fully understand that you can get the 150mm drop and just not use all of it, but what does it matter? Why complain about 100mm and 125mm posts then? The smaller posts are easier to find and sometimes even cheaper.
As for "having the post the same height the whole ride" defeating the purpose of the post - that's exactly what I was getting at. Neither of my current bikes have a dropper, and every demo and rental that i've ridden that has had a dropper I didn't end up using it because I didn't like it when I tried it. So why would I buy a dropper then?
I think that's what it comes down to: I have quite long legs so I need the reverb maxed in the frame to get the saddle high enough for climbing, which means when it's dropped to minimum, it's still not very low.
@mikekazimer @mikelevy @RichardCunningham
@jervis
Ditto and I'm on a 170 reverb already....
9point8 have finally got their 200mm post available...so there is an option
To give you folks an idea of my post heights: extended and lowered. Bike on a tiny bit of an angle, but when reverb is lowered my saddle is actually still above my bars, hence longer post required.
@atrokz I wholeheartedly disagree. Di2 integration(& the shock integration they promised being actually available) would sell this post for me. All I've wanted since they announced Di2 for MTB was a left hand remote that does the following:
Bottom lever controls dropper. drop post all the way down? automatically open up shock compression. Post goes all the way up? automatically put shock in mid compression setting.
Top button does one of two things(I'd have to ride it to see which one I valued more, or maybe it can do both via short press/long press.) It either: toggles climb mode on the shock, or: it drops the post to a defined mid drop position. hopefully one I can define myself.
I think multiple 'hot keyed' buttons would be cool as well, mainly for controlling suspension.
However, everything else I mentioned? doable today, with current Di2, (though I admit the actual availability of electronic controlled shocks has been terrible.)
& again, the benefit to electronic actuation is the integration. Though you do bring up a good point about actuation: Geoff Kabush said the easier actuation of his ICD "slider" thing made a real difference when he was at redline, so it's not just about it "being too hard."
Having a port on the frame to plug into, which has internal leads and ports along the frame for different components would be pretty cool. I'm not a fan of wireless in this application thanks to my Mfg Eng experience with military systems, but a variety of ports and a simple port into the head tube area would be pretty cool.
1. There is one less cable in or on my bike. That's always welcome.
2. I can easily swap that setup from my XC bike to my trail bike and vice versa. I don't need to buy multiple dropper posts for my quiver.
IF it was wired, then it would appeal less to me and offer no real improvement over my current dropper.
Imagine getting into your car, start it and it sends a wireless signal to the starter motor. Shift into gear and it sends a wireless signal. Depress the gas and it sends a wireless signal. Adjust the mirrors? Wireless signal. Same for motorbikes as they are closely related. Imagine wireless shifting on anything but a bike.... Imagine how long your job at ________ would last if you came up with these ideas. Not very long.
Also, a wired system would be almost as easy to swap. When all you have to do unplug is a wire, disconnecting/reconnecting a post would take almost no time. It would be a little more expensive since you'd need to have to remotes set up, but if it's hooked to Di2, then that's just an extra wire off of your junction box.
Not that the argument that people are going to swap droppers between bikes makes much sense to me: adjusting seat angle takes far more time than disconnecting any of the cable actuated posts that actually have a disconnect. heck, even a reverb connectamajig is pretty quick.

@atrokz: IF you belong to small percentage of dropper post users truly concerned about this, then there are 10-20 alternatives currently on the market that will suit your needs. Most non-competitive cyclists (the vast majority of users, especially those who actually pay for products not get paid to use them) could care less.
I still favor a hybrid solution overall: Wires between the components, batteries, & controller, but wireless for the shifters to eliminate the wire routing from the bars.

I do not understand why they don't just flip the way the cable goes in: Put the head in the barrel which is at the bottom of the post, fasten and cut the cable at the lever. Waaaaaaaaaaay easier to set up and adjust. And doesn't even need a lot of change.. just a different barrel and a bolt at the lever.
Also, the saddle clamp. What the heck? Why would you even begin to fiddle with that stuff, trying to adjust the seat angle, when there is a very clever two-bolt design out there, used on hundreds of off-the-mill seatposts and a couple of droppers (Reverb, Thomson at least)?!
Also not sure why Shimano went with the band-aid fix of a (very good) Taiwan factory item. Probably more to do with OE pressures.
The countour is already out there in other (externally routed and longer drop) versions fyi. The Ascend will be priced as you would expect from BX and really is very good regardless of price (also due in October time). Pictures on my profile if anyones interested.
I slowly stopped using Shimano parts except for pedals. OX was a game changer and XX was the final nail in the coffin. SRAM knows what I want and they Deliver. My SRAM drivetrains just work and I don't really have to think about them. Never owned a Reverb and the ones I've used have been just ok. The new Guides are defiantly better than any Shimano Brake I've used. Then again the only Shimano brakes and drivetrains I've used in years have been on demo bikes. The performance is usually good but not great. But that's just my experience. Seriously does anybody use a front derailleur anymore? Even my kids bikes are 1x.
Now when will Hope make a dropper? I bet that would be bombproof and have awesome after sales support. As well as being completely user serviced.
I have short legs so I had to go with 75mm Specialized.
Still fine. 1" of seat post out from collar.
$300 on jenson/competitive
