Acros is an elite German components maker that offers an index-shifting derailleur system actuated by a pair of slim hydraulic lines that reportedly weighs only 426.4 grams ready to rock. Yes; you heard it correctly—front and rear derailleurs, right and left shift levers and all hoses filled with mineral fluid. The Acros A-GE system isn’t a prototype pipe dream either. Acros has 250 sets boxed and ready for sale at a surely-not-for-everyone projected retail price of $2306 US dollars.

Acros A-GE Hydraulic Shifting Basics

Beautifully machined from aluminum, the Acros A-GE transmission promises to either set a new standard, or hearken to the mid-1990s when a half-dozen North American machine shops took a crack at Shimano with expensive, multi-colored copies of existing gear-changers. Potentially, the Acros A.GE 1.1 hydraulic transmission has some unique features that cannot be attained using cables. Time will tell, but if it operates as advertized, the Acros system may be the first exception to the, nobody-can-beat-Shimano’s derailleur technology rule. Pinkbike grilled Acros about the benefits of its hydraulic shifting system and prepared this special report to introduce the concept.


Acros reinvented handlebar shift lever. Pressing the paddle shifter at a slight angle, up or down, determines the direction of the gear change.
Acros reinvented handlebar shift lever. Pressing the paddle shifter at a slight angle, up or down, determines the direction of the gear change.

What is the major benefit that A-GE brings to the table?

Acros says that the primary reason they produced a hydraulic shifting system was that it offered the least amount of friction. The A-GE shifting lever actuates the derailleur with a “UNI-FORCE” two-line, push-pull design that nearly eliminates the need for stiff return springs. Shifting feels light and consistent across the entire range of gears.


Are the shift levers conventional?

No. A-GE Shifters have a single thumb paddle that shifts up or down the gearing range. Pushing the lever upwards shifts to a taller gear and pushing the lever downwards downshifts. One to three shifts can be managed with a single push. Switching the hydraulic lines allows the user to reverse the shifting from “top-normal” to “low-normal” as wished.


Can the shift levers be used with any brake levers?

Yes. Acros’ MY-MOVE lever mounts allow the levers to be positioned in a number of ergonomic locations, and both ahead or behind the brake lever.


How can Acros derailleurs and shifters be lighter than SRAM or Shimano and still be strong?

We will address the durability issue when Pinkbike gives the A-GE a thorough test. Acros states that much of the weight savings are derived from the elimination of steel cables and steel-wrapped cable housing, which add up quickly. In addition, push-pull hydraulics eliminates the need for steel return springs on both derailleurs. Acros makes extensive use of alloy Torx hardware to shave off a few more grams as well.


Will I be stuck buying an Acros-compatible crankset, chain and cassette?

Acros A-GE uses a timing device called a Raster Rod which can be switched out to adapt the derailleur shifting to all conventional eight, nine and ten-speed cassettes and chains.


What happens if I get air in the hydraulic line?

Air must be bled from the system like a hydraulic brake. This is unlikely to happen, however, because Acros hydraulic shifting is a closed system and is not exposed to excessive heat, nor is it required to compensate for pad wear like a hydraulic brake. Should the Acros system be compromised, its front and rear derailleurs can be positioned by hand to adjust for an acceptable gear and will remain there until you get back to the trailhead.


Will it survive a crash?

We have learned that hydraulic brake lines are far tougher than first anticipated—it’s rare that anyone damages one in a crash. Acros’ shift lines are smaller and we assume, more fragile than a brake hose, but it should be noted that a hydraulic hose will still shift properly when badly kinked, as long as fluid can pass through the damaged area. For a downhiller, being able to shift after a crash mangled the derailleur cable could mean a podium finish.


Can I get a short-cage rear derailleur for my DH ride?

The first 250 systems were made with medium cages, but Acros will make long and short-cage versions as well.


Evidence of intensive machining is obvious on every piece of the Acros rear derailleur this is the medium-cage version

Mechanically, are there any compelling reasons to switch from a perfectly great working SRAM X.0 or Shimano XTR to an Acros hydraulic system?

Riders who live in extreme cold have all suffered failures when water freezes inside the housing and the cables simply won’t budge, and a sealed hydraulic system will operate happily in muddy, sloppy conditions that can make shifting cable-actuated systems a wrestling match. The single-paddle shifter could offer an advantage. SRAM experimented with its push-push single-lever road system when it developed XX, but abandoned it because of the excessive lever pressure required to push against the derailleurs return springs. The hydraulic action of Acros A-GE does not require return springs, so it could be an improvement.


Is the Acros A-GE the first hydraulic shifting system?

No, but it may be the first complete hydraulic derailleur transmission. California downhill racer Scott Fyfe designed and marketed a hydraulic shifting system under the S.A.F.E brand in the mid 1990s. The S.A.F.E shifter operated a piston and cylinder that fit into the rear derailleur housing stop and pulled a conventional changer with a short wire link.


Is the Acros the inventor of the system?

NO. We asked Acros' Marius Wrede and he said: "Christoph Muthers invented the system and presented it at the Eurobike 2006. In that moment we saw the potential of the system and that it fits to Acros. We stayed contact ever since and helped in little sourcings. In 2009 Christoph asked us if we are still interested in continuing the project. We did not hesitate and said YES! Christoph is now in our R&D team and we have modified the hydraulic gear to meet industrial standards as well as keeping up with the new “standards” in mountain biking."


What does Pinkbike think about Acros hydraulic shifting?

Anyone who rides hard is going to tear up equipment, and 2300 dollars is a lot of money to spend on shifters and derailleurs that probably will have to be replaced in a few years. That said, racers and anyone who rides in extreme weather or terrain could benefit from a shifting system that has the potential to shrug off nature’s fury or survive a serious crash.

 I could get a whole bike for that price

 For $2300, I can think of a lot more things to spend on, rather than a Shifter/Derailleur . My SRAM X9 setup has done me well, and I'm sticking with it.

 one question: why? whyyyyy??? people!!! stop doing unecessary things! specialy when they cost ur life!
  • + 46
 yeah mountain biking is expensive, and most parts well worth it. but that price is just ripping the piss!

 id sooner get saint, but lets face it, its got time to grow and maybe become cheaper. that mech is sexy!

 i want hydraulic actuated suspension linkage. Big Grin

 It is not unecessary at all, it is evolution..

 yoooo i hope thats i typo couse $2,306 thats f*ckinn stupppppidly expesnive WTFFFFFFFFFFF...............
  • + 24
 agreed combee, this will get cheaper over time, like hydraulic seatposts, adjustable geometry, and every other single innovation. it has to start expensive because of the small scale they start on!
  • + 21
 yeah its really expensive but its a great concept. if it proves to work well and comes down in price i could see this becoming more popular in the future. innovation like this is what keeps our sport advancing
  • + 19
 Wait. Is it still April fool's???
  • + 53
 If they looked at doing this but within a gearbox, they'd make a killing. People are looking beyond rear mech's and hangers these days. if they can create a gearbox that is small and light enough to go onto/into a Dh frame and not upset the suspension set up, Then and only then could they say they've found the next step in Mountain biking's evolution.

Great Idea but it has massive potential else where.
  • + 7
 I have been waiting for something like this for a long time! It looks sexy and should have the performance to back it. For those of you whining about the price, I guarantee Akros didn't design this for everyone. It's for those with the spare $$ and want to try out the future of mountain biking now! I see this catching on and sram and shimano following suit in a few years. Who knows... in 5 years this system could cost as much as running full saint!
  • + 2
 i agree with gazmataz, but the painful truth is that gearboxes are a lonngg way off, simply because shimano dont want to do it yet.
edit: (sure, you can get a gearbox bike, but its not the accepted norm.)
  • + 2
 I think this is an awesome idea, sure it costs now and will only be available to the lucky few who can afford it but technology trickles down and hopefully before ever the rest of us will be able to afford it, besause, for one i am fed up of w**key shifting from mud clogged cables.
  • + 1
 "Can the shift levers be used with any brake levers?" haha i thought it meant 'instead of' for a second, come on now, dont be silly...
  • + 0
 Little too exotic. I mean, does every single piece have to be machined? Im sure we could bring the price on this system back down to earth if some of the parts were not.
  • + 7
 still cheaper than Di2
  • + 3
 It's an awesome concept (minus the shifter, i could see having to push up or push down at an angle while riding being kind of a burden, and lead to a lot of upshifts when you actually want a downshift.) That being said, $2300? If they put these in the same price point as xtr it would kill, but who can afford to drop that much coin on a drivetrain?
  • + 4
 Its really trick, but Its a solution to a problem nobody had. I mean, an XTR level drivetrain with nice fresh cables shifts pretty damn good.
  • + 4
 Better they made hydro steering
  • + 9
 I'll make sure I pick up a set right after I get some $800 Magura MT-Eight brakes and Easton Haven wheels... Oh wait, maybe I can put that money toward a house instead.
  • + 8
 Yeah but if people always said that technology would never advance; people said that when the first 8 + 9 speed cassettes came in and they are the standard now.

Currently yes, it's a bit pointless for that kind of price tag but give it time to come down in price I wouldn't be surprised if 10 years on from now hydraulic shifting is standard; similar to v-brakes and hydraulic brakes now.
  • + 1
 a bit pricey?
  • + 11
 See I dont think its like v-brakesdisc brakes. Its more like hydraulic rim brakes. Hydraulic, yes. Powerful, you betcha. But still a rim brake just like this is still a derailleur.
  • + 1
 @Iceman You have a point,Lets just hope it gets cheaper.
  • + 3
 When super high tech hydraulic brakes and nice shifters came out, they didn't cost the equivalent to 2300 bucks. They were expensive but obtainable to a good handful, trickled down used, and caught on. I don't know a single person who could approach buying these, I will never personally see a set on the trail, they will as a result never trickle down in the used market and catch on.
  • + 0
 If I had that much money to burn, I'd consider a Rolf wheelset.
  • + 4
 Yeah I see where you are coming from but then again the same could be said for the hammerschmidt and I've seen a fair few of them around now? Either way I have a suspicion by the time these come down in price someone may have developed a light gearbox; zerode seem well on their way....
  • + 1
 Hammershmidts price doesn't even approach the price of these, and Hammerschmidt is something totally unique, like DARKSTAR63 said, these are still just dérailleurs.
  • + 3
 fanta should buy them
  • + 4
 You're all missing the point. Next year this will probably cost $200 for the rear set up...Everything starts out expensive and drops in price over time.
  • + 2
 Its definatly cool, Im not going to deny that. And Im glad people are developing these things. I just dont think its the future of bicycle shifting. A hydraulically controlled gearbox............that would be something a bit more revolutionary.

 @suicidedownhiller I hope you are exaggerating a TON on purpose.

 I don't see the reason for hydraulic shifting. I think I'd put my trust into a good old fashion XTR or XX or XO or anything but this. + i would save a lot of money. Not saying their bad, but there is really no need for them.

 No, I wouldn't be surprised at all if it's that cheap next year.

 Wow, just wow. The price of these is not going to over 500% less next year.

 Pinkbike screwed up. They only include the weight of 1 shifter, total weight for an entire setup is 426.35g. This is about the same weight as the 5ROT system in 2007... which is what this is. http://www.light-bikes.de/eng/2007/03/02/5rot-hydraulic-shifting/
  • + 2
 Its the very same system. Just re-branded.
  • + 1
 This IS the near future of Mountain Bikes. Except it'll be a tenth of the price in 5 years.
  • + 1
 I was just about to mention the Rot5 (or 5Rot) system, because the article clearly states that this is the first all-hydraulic shifting system... and the 5Rot was exactly that, and it's not even mentioned in passing in the article.
  • - 3
 This is like putting hydraulic brakes on a horse drawn carriage. I go through four or five rear deraileurs a year and I would consider myself a fairly modest rider. And at a price that is fit for a gear box... let's see some innovation! Good luck with the market on this one.
  • + 10
 you go through 5 or 6 rear derailleurs a year? Either you don't take care of your stuff or you're buying crappy parts, because that's not normal dude...
  • + 1
 have they sold 1 set with that price
  • + 1
 Just me I guess? I find deraileurs are rock magnets. Perhaps depends where and how often you ride??

 I can't wait for the day that we actually get to use what is best, rather than what is shoved down our throats and we get to pay tons of money for. Does anyone REALLY think this is necessary? Does anyone REALLY think that any derailleur in the world is better than a gear box? Funny how money can either propel a sport forward, (or in this case) slow it way, way, way down.
  • + 1
 At least its cheaper than a Carbon V-10 Smile
  • + 1

 Bad move on acros to set the price so high when sram or shimano will come out with something next year for less than half the price

 I is however about $2.7k cheaper than the Shinamo Dura- Ace Di2 electronic shifting set up. However with that you get all that is offered here plus BB, crankset, chain, cassette and brakes. But it is a roadie groupo

 what are you recking them on? I rode an xt for 3-4 years, even slammed it on the edge of a ladder a couple times, and it always worked great. Only reason i replaced it is because the barrel adjust thread stripped out, so now im coming up on year one of riding an x9

 I bet most of you didn`t remember the Shimano Airlines from the Year 2000? That was an Pneumatic Shifting System for 1000 $... There was no Market for such stuff and i think today there is also no market...
  • + 2
 When you spend a ton of money on a frame or suspension, you actively enjoy that part the entire time you ride. I don't really spend more than 1 minute total shifting during a ride so I don't need a shifter that will make it more pleasurable. And once its in gear, as long as it stays in gear, there is zero different between this and a $100 shift system besides a few grams and looks.

 @philler

i think a fair few people would remember airlines

 I'd ride Airlines... they look dope and they probably sound badass when you shift.

 $2300 for a set of front and rear shifters isn't out of line with other high end solutions. Shimano's Airlines were over a grand at launch and it was only for the rear. And they had to be refilled every couple hundred shifts.

 If it is to shifting what hydralic brakes were to braking then it will be the new norm, the price is only that huge because the first run that is started with is the top of the line model, there were none of the SRAM XX innovations in the lower groupsets until XX had been on the shelves for a year, if the difference between this and cable shifting is as good as the difference between hydraulic brakes and cable brakes then it will soon be made in much larger quantity and the price will come down alot, and heavier versions with not as many features will be made, for example Deore is a hell of a lot cheaper than XTR, but it still works on the same principal it is just heavier and has less features. So give it time, if it as good as it has the potential to be then it will catch on, and come down in price.

 I was afraid this would happen......... Sometimes I just want the world to stop evolving, why do we need this?? Seriously we have been shifting using cables for hundreds of years and ppl just want shifting to be easier or more efficient when we all know shifting is one of the last things to be upgraded on a mtb because it already is efficient. Some may say this is more environmentally friendly but you know that's bs b/c it costs more to make these parts then it is to make steel cables.We all know that this will revolutionize and will eventually be stock on all mountain bikes in idk maybe 30, 40 years?? Just look at cars, they parallel park themselves now, humans have the brain capacity to do that themselves but people want less work. I truly believe that the world is going to end up like Wall E.

that said last spring I bought a carbon santa cruz with XT, in the fall I upgraded the cranks, bars, seat post. This spring I upgraded wheels... maybe this fall??? and then if i get some nice magura carbon brakes I'll have the sickest bike ever...

 Then try powercordz, a Kelvar cable system that will not stretch.... only downside is the cables are $12 a pop. I have have the same deraileur cable on my transition double for 1-1/2 seasons, haven't had to touch it once!

  • + 2
 Well, Acros somehow has to compensate for the development costs. It seems they want to have that done with 250 very high priced sets, that will probably be worth even more to collectors if the system proves to be revolutionizing high-end shifting.

The important question is: how expensive is the production really? I could imagine that the first "real" series will sell for prices like XTR or XX.

Anyways, congratulations for their engineering ingenuity. Having experienced the superb quality of earlier Acros products, I guess they are here to stay.
  • + 1
 These prices are likely list prices, not street prices. In Canada the list price for an XTR derailleur is something like $260, an XX power dome cassette is $550, etc.

 i think that we shouldnt introduce anything electronic to bikes ever. add ons like lights and computers are fine, but a bike should be 100% self sustaining with mechanics.
  • + 2
 Being a bike mechanic myself i know that mechanical system's will, for the most part, be more reliable, however, cables can fail. Also have you ever tried the Di2? it's pretty freeking perfect as far as shifting goes, and doesn't actually weigh any more than a regular set up. They're both crazy money for sure though, that's always going to be the major downfall with alternative system's like these. Unless your're doing a lake jump, or something that completely immerses Di2 in water, then they are surprisingly robust and water tight, being in scotland, It's seen it's fair share of torrential downpours and never had a problem!
  • + 2
 my reasoning isnt about failure, its about how electronics destroy the basic idea of a bike: It is powered by you.
[Reply]
  • + 5
 IMO this is a move in the wrong direction. We need to eliminate rear mechs, not improve them! And at this price point, who can afford to replace 2 or 3 of them a year, like I do.

 Buaha "love the sceptics" I'm sure sceptics were bitched too when Hitler was giving speeches on better, more efficient race and getting rid of undeveloped ones. Then he was gasing disabled and mentally Ill to reduce the costs of running a country and get rid of weaker individuals. I'm sure going forward and Darwins stuff was on his lips quite often.

Dude! There is way not enough ACTIVE Scepticism in our world so back off. Humans evolve buahaha, into sales bullshitters and overweight diabetics buahaha Big Grin as for nature we devolve, or retardate.

 Yeah, saint brakes have been around forever and are definitely not an evolution of previous brake designs. You don't run v brakes on your AM bike do you? No, because someone came up with something better... and it caught on.

and i would spend the money on it, maybe ... but it would need to come with something like a 10 year warranty for everything
if it breaks ... if i crash and break it ... any thing any thing any thing ... i want to go the next 10 years never having to worry about buying a new shifter or derailleur

lets face it ladies and gents ... this is the way of the future ... no choice about it ...
5 years ago it was 8 speed cassette now 9's and the 10's are being phased in forcing you to get new shifters, chain, cassette, derailleur and 10sp chain rings // not like you can just put the new 10sp sram derailleur on a 9 speed cassette (ive tried with sram X9 10speed on a 9speed cassette - its a no go :-/ )

AND AFTER 90% OF bikes run a 10 speed they have to create the new and improved product so we keep buying new stuff
low and behold ... the new stuff ... at least it looks good
and with prices like that Acros is going to be the ferrari of the bike world

 Considering its almost brand new hopefully the price will be brought down over time as more companies jump on the bandwagon making more competition for pricing , i think its a great piece of engineering but to be honest surely the reinvention is more needed in something to change the gears itself rather than what it is shifted by .
[Reply]
  • + 2
 As a system its been in development for over 5 years and at 175g lighter than XTR there is already a lot of retail interest. In the UK, we've already taken orders for a handful of sets.

Acros are a high end German manufacturer and the production will not move from in house. Break the set down, there are 248 individual parts at a cost of $2300, that works out at just $9 per part. To machine in house, anodise, laser etch etc etc, its not all that bad. Dont forget about all the small pistons etc that are super expensive to machine.

The whole system is fully rebuildable. Trash a mech and you can completely rebuild it at home. By the time you bought a XX gruppo, trashed 2 mechs, you'll only be a few hundred $ away from this system.

The original concept was realised by Christian Muthers under the 5Rot brand. This never made production due to the development and manufacture costs, not to mention the logistics! Christian now works for Acros as a top designer and sold the designs to them. They had the power and funding to turn 5Rot into a reality. Its taken 5 years of development, even from the point Christian had it to get it to market!

It runs on a fully sealed system which is dead easy to bleed. You simply remove 2 bleed screws from the shifter and push fluid all the way down and round the whole system. It is adjustable both at the mech and shifter if you get issues on the trail, simply by adjusting the piston screws.

Production versions will house the 2 smaller cables into one so you wont end up with more cables than at the moment.

 i bought my rear mech from christoph a few years ago, before it went to acros,,, rode it for several years till it needed bleeding and a slightly longer hose.. for the rest it took some hits and so,.. but its still running smooth.. i say a win.. if your doing it for the weight and looks.. overal it does perform a little better than conventional mechs.. but since the shadow mech came out.. i'd say you have to love it to buy it.. i did and i still do..

 The product looks beautiful but like others obove have said, it's just flogging a dead horse really. The future is internal gear hubs (you could buy 2 of them for this price!!) or gearbox's.

 Saw this a few years ago and looked into why no one else (Shimano Sram) was doing the same. From a quick scan around the net, it seems that Shimano hold patients for hydraulic shifting. Does this have something to do with the price perhaps? Either way it's been a long time coming, so let's have a few more players in the market. Well done Acros, I'm sure it will be made beautifully like their other products.

 great idea n everything but far too pricey.. I think companies should try to focus more on better alternatives to top quality components (and frames) that dont cost you an arm and a leg - many people would love to see mountain biking become a well known sport across the world but one of the things preventing that is the money you have to invest just to really even start, that is all.
[Reply]

 If they looked at doing this but within a gearbox, they'd make a killing. People are looking beyond rear mech's and hangers these days. if they can create a gearbox that is small and light enough to go onto/into a Dh frame and not upset the suspension set up, Then and only then could they say they've found the next step in Mountain biking's evolution.

Great Idea but it has massive potential else where.

 probably could have saved a few hundred off the retail if they would have used forgings instead of having to machine the parts on really expensive CNC machines (would have been stronger too). But they're German, so I guess thats how its gots to be. Looks nice though. I want my Air Lines back.

 the problem with forging would be the tolerances, probably forging and then machine the low tolerance parts of the system
  • + 2
 that is how its done. Get the complex curves done in the forging process, then tidy everything up on the CNC mill. Doing it that way would make a stronger part (on paper anyway), and make the lines smoother. but then again some people see some sort of cool factor in machine lines.

 I'm always pretty skeptical of this new stuff. Seems like higher performance only really helps when the current performance is holding you back.
Cable disk brakes where holding me back. I love my hydros.
My shifter-derailleur combo only holds me back when I don't plan my shift or my hanger is bent. Only having 9 cogs on my cassette doesn't hold me back so I don't need 10. In fact 8 would probably be good enough for me. (Freeride doesn't require a regular cadence.)

If your shifter-derailleur combo is holding you back and it's not just a lack of shifting skill then you need something better. Start saving for the hydro-shifters. The rest of us are probably good for now and will switch when the industry stops making parts for the old style.

 i have always been 100% for innovation , new concepts and progression but facing this , i cant get over the fact that ;
most rider ahave fixed derailler problems , on the trails , in races , whit anything to could get their hands on.
shifter , deraillers and cables are changed in parking lots in minutes for a couple of bucks (ok , maybe $50-$75 for rear SLX of X7 that can get you going)
i dont see that hapenning whit these hydrualics , regardless of their price.
that's a major setback.

it's the same whit hydro brakes , i know. but the performance from hydro brakes makes the trouble (when compared to machanical disk brakes) worth it.
i dont see that benefit for running a hydraulic transmission setup.

only time will tell i guess.

 jeez obviously the price is going to be ridiculous but so was all the other big inventions when they first came out. Disk brakes were hugely expensive when they first came out and now they are on almost all mountain bikes. if this system truly works well and offers a big advantage over the traditional shifting then the price will go down and I could see this being standard on lots of mountain bikes. but i doubt that will happen for another 10 years or so

 Cables are so limited and require a spring to operate.
So why when you have the power of hydraulics continue to use a spring and not a closed system?

 they probably do cost a lot to make. My guess is that they were done on some sort of half million dollar machine with another 200k in tooling. Operating on of those is not very cheap nor is the design nor the set up. And since there is a bunch of parts made with complex geometries plus the limited run part of the deal and yeah, $2300 is not that surprising. If they were to have forged the parts, then machined them and made 25000 units I am sure it would have been under a grand. But then it wouldn't have garnered nearly as much attention.

 Don't want any stretched cables? Run PowerCordz. Problem solved at a small fraction of the cost of this system.

 true dat! Lighter than standard cables as well, and harder wearing. And none of the faff of hydraulic, brakes is one thing, but gears, I mean they're only doing it because no-one has yet right? D:

 Never realized shifting was incredibly hard with cables - waste of money and innovation for a product that's not really needed. How about getting rid of the back derailleur all together - like the rohloff - but refine it, improve it and make it bomb proof and serviceable if ever need be! Then get it on as much OEM as possible to make it affordable! Hmmmm.
