Reverb Stealth Telescoping Post - First Look

Jul 1, 2011
by Mike Levy  
Doing away with the clutter: Although there are still a few holdouts - mainly only those who have yet to try one - dropper posts have arguably been one of the most influential pieces of bike kit to arrive on the scene in the last few years. Sure, various models have been available for over a decade now, but the recent push in the refinement of telescoping seat posts have seen them go from quirky to mainstream in a very short amount of time. While reliability and function have jumped leaps and bounds in that time, one point of contention has continued to be an issue for most designs - that pesky cable. Lowering the saddle instantly makes the bike far more fun to ride, but it can sometimes take a bit of ingenuity (along with a few zip ties) to keep the extra cable from rubbing your tire, catching your foot or generally causing a headache. With a hydraulic line that is routed internally through the frame and into the bottom of the post, thereby eliminating not only the surplus cable when the saddle is lowered, but also greatly cleaning up the routing and making for a more reliable system overall, RockShox's Reverb Stealth looks to remove that nuisance.

RockShox Reverb Stealth
This cutaway of a Scott Genius LT shows the Reverb Stealth's hidden routing through the frame. It enters the down tube at a point about a third of the way up from the bottom bracket, but I'm sure that we'll see other designs that have the hydraulic line disappear into the frame closer to the head tube.
Reverb Stealth
The Reverb Stealth's internals have been inverted to allow the hydraulic line to exit from the bottom of the post.

RockShox Reverb Stealth details:

- Hose exits from bottom of post, creating a non-moving hose position to eliminate surplus cable and make for cleaner routing
- 125mm of infinite adjustment
- Hydraulically controlled (no cable to contaminate or stretch)
- Improved hose fitting for increased durability
- Will come as original equipment on Scott Genius LT 10 and 20 bikes, as well as select Trek models

The details: While 125mm travel Reverb Stealth still uses air pressure to return to full travel, along with an internal floating piston to separate the air from the oil - the very same as is used on the standard Reverb - the internals have been inverted to allow the hydraulic line to exit from the bottom instead of the post's head. This lets the hose be routed internally through the frame for a much cleaner and more reliable setup, although for now it means that the post will only come stock on certain Scott and Trek models, and that it won't be available for aftermarket purchase due to slightly more complicated installation. All Reverb Stealths will ship to the dealer with a full bleed kit, hose coupler and MMX spacer. With the MMX spacer in place, Stealth’s remote lever can standalone on the handlebar, remove the MMX spacer and you can use the remote as the mounting clamp for your Avid brakes and SRAM shifters.

Unfortunately for current Reverb owners, although not surprisingly, original Reverbs will not be able to be converted to the Stealth configuration. While the line exits at the bottom of the post and is routed internally through the frame, RockShox says that the same simple bleeding process is used as on the standard Reverb, most likely meaning that adjusting hose length will also not require a bleed as well.

For 2012 the Reverb Stealth will come stock on select Scott and Trek models, although I would expect that list to get longer down the road. Although the routing is clean and simple, manufacturers will need to modify their frames in order to accept the Stealth's hidden routing - this could be as simple as clean entry and exit points, or may even include internal hose guides on some models.

Some of my time in the French Alps was spent trying to keep Monster Energy - Specialized rider Brendan Fairclough in sight (I wasn't very successful). Brendan was aboard his Reverb equipped Specialized Enduro, cruising French singletrack one second and then boosting the smallest of lips the next second - making use of his dropper post the entire time.

Pinkbike's take: We've got loads of time on multiple Reverb posts and are convinced that it is the class of the field - no steel cable to get rusty or stretch, 125mm of infinitely adjustable travel and great reliability to boot. The Reverb Stealth, with its stationary hose that is routed internally through the frame, looks to be the next step as far as performance and reliability in dropper posts is concerned. While only lucky riders who pick up select 2012 Trek and Scott models will be able to get their paws on the Reverb Stealth, we'd be surprised to not see it on more and more bikes in the future. We also hope that it becomes available for aftermarket purchase as well, although this may be decided by how frame manufacturers respond to the routing challenges of the new post.

 I'm running the "old" Reverb and I have no problem with cable routing but it must be very dependent on frame design. I confirm, this seatpost is amazing. It will make your riding awesome but I guess it depends a lot on terrain you ride. For XC/trail riding it's awesome to squeeze all the juices of every trail, but not sure for AM, and definitely not sure for FR.

But this one here is a good idea, it gets crazy with how many cables you get on top of your bike these days: 2x gears, 2x brakes, fork lockout, maybe even shock lockout (fkn mountain roadies...) now adjustable seatpost... aaaaa!
  • 3 4
 hmm, now i have to drill a hole in my frames for the seatpost cable? .....
  • 16 1
 i love drilling holes in my frame, not only does it make my bike lighter, but on a good day i can catch butterflies..... structural integrity is is for the weak!

 It certainly goes without saying that you i>shouldn't/i> be drilling holes in your frame for this post's routing. But I love the integration and forward thinking of the internal routing from Scott and Trek - it does make a lot of sense.
  • 1 2
 a rear shock lockout is nothing new. scott already uses this on their XC bikes, they call it TWIN LOCKOUT which locks out the front and rear suspension at the same time. besides, what's wrong with having all the options? mountain biking is a young sport and unfortunately you need to have a tool like a mountain bike to go mountain biking and having the best tool can make people better.

This article is a height adjustable seatpost? Don't know what you're talking about with remote shock lockouts...

 Say whatever you want: it looks geeky... it is pretty hard to believe that a non XC Wcup racer needs a lockout. In fact not all of them use it. My favourite ever was a guy I've met who had all 7 possible cables, a huge light (on a day ride!!!), GPS + GoPro camera with like 5 mounts all over his bike. On top of that he listened to Iphone on his arm fk... I bet he was posting his location on facebook all the time

We're not gonna kill anyone for having these but fk...

 This cable routing might be a good idea, if the Reverb comes stock on the bike, meaning the bike´s frame has been designed with the internal cable routing already. But what if my oldy 2008 Giant Reign 0 doesn´t have this internal cable routing?? I consider this is nothing much to brag about from Rock Shox, I was hoping to hear that the 2012 Reverb already sorted all the headaches ( design and manufacturing issues) the 2011 produced. I my self went for a KS i950 instead after all the problems the Reverb had.
  • 2 0
 There was another company whose name I forget that had the hose exiting right above the seat clamp, which essentially does the same thing as the cable doesn't have excess length when the seat is all the way down, and doesn't require a specific frame.
  • 2 0
 never thought of that but that would be for me that would be a WAY better (and Im thinking commercial) solution. its the excess hose when dropped that causes the problems. If the hose was fixed to the collar then there would be no cable bend when dropped, it would just be static.

then again, you would think these guys have considered this. Im sure theyre smarter than overlook such a simple solution.

 or most likely the solution is patented and they had to invent another way which may be inferior.

 Your either thinking about Blackx, or the gravity dropper ones, and also KS is making one like that now, i think they are getting the hint now

 It was KS, if I remember correctly they were showing it off at interbike this year.

 I've got two Reverbs and they've been outstanding so far...easy to service, very reliable, plenty of travel....this version seems like a good idea but I've had no problems with routing my cables for my rides...maybe for certain frames it could help though...

 ...Two reverbs? for each of your arses??...

 he might be a shmuck, but hearing that someone owns two Reverbs just puts off people, you know... you upperclass basterd... I bet you have Lacoste V-neck pullover... I buy two more on monday, how about that HA?!... crap - I need to buy a bike to fit the third one as well... crap #2 - my middle-class HT has 27.2 seat tube... I need two more bikes... I hate you! hate you!

crap... if I buy two bikes and two reverbs, I won't be middleclass anymore...

 It's a nice idea to get rid of that loop of cable when the post is down but it does now make what used to be the easiest part of the bike to remove some what more difficult to take out.
  • 1 0
 For sure, but when the Reverb is slammed in the frame and the post is dropped all of the way it should only be a few inches above the top of the seat clamp.
  • 1 0
 i agree. makes you think this advantage can be more of a disadvantage when its time to remove the seat post.

 I've got a sweet adjustable height seatpost; it's super light, requires no servicing, doesn't have any lateral play like the crank brothers droppers do, has no cable routing issues, and doesn't tie up real estate on my handlebars. Oh and it's cheap and nobody's going to develop an "improved" version next month.....Thomson

 I think maybe you're missing the point. Facepalm

 Well, if we are talking about this type of height adjustable seatpost, Thomson is far from being cheap...

 It's nice to have a look at this great post again, but internal cable routing of any kind is hardly an innovation! Why not route the brakes, derailleurs etc inside too? Gimme a break Scott/Trek/Rockshox. If we cut a $5000 bike in half we'll get some attention... that's all this is about.
  • 1 0
 I have had this idea since the dropper posts inception, the cable/ line needs to bixed in place, a moving line causes all kinds of troubles. My thought was a solenoid and then running the wires up through the colar and along the top tube to the handlebar remote, something similar to the Dura ace solenoid shifting.

One problem I see for internal routing of anything is a cable/ hose that slaps around a bit, would be pretty annoying to not be able to stop the sound.
  • 1 0
 With an electric solution, there could easily be a disconnect, to make removing the seatpost once again easy!
  • 1 0
 I always thought that an internal integrated height adjust seatpost would be a cool idea. Like make it part of the frame. Hydraulic or pneumatic. Then figure out some way to make it compatible with any seat post out there. It could definitely happen.
  • 3 0
 Sucks if you need to remove your post for transport. I really wish they could have the hose exit the top cap on the lower tube.
  • 1 0
 This new part won't work on every frame, but for those with interrupted seat tubes, and frames designed for this, it is great. Makes for a clean looking post. I have a KS, and will never go back to a standard seat post for trail riding again.
  • 4 0
 I would love to have one, too bad they cost an arm and a leg.
  • 4 2
 no they don't cost an arm and an leg considering how much change to your riding this design brings. If you ride aggro XC, AM in mixed terrain, this will change your world 100times more than investing in new brakes, frame, fork or whatever else. People tend to spend most money on E-volution of their bikes rather than getting balls to do some RE-volution.
  • 1 0
 They're getting cheaper, as does every new piece of technology. You pay big $$ to be an early adopter, but a little down the road they'll be affordable enough for everyone to have.

And like WAKI said, they make a huge difference in your ride.

 one our local bikeshops has a cannondale jekyll with this post, only the other one was smaller, i took it for a test ride and it was badass. these seat posts were a great idea

 WANT. Would go right on my 2011 Coilair... *Looks around for money*

 with my bike the 2006 sx the frame design has an open tube that is the seat tube it will work perfectly for my bike and i am glad to see this. i will deffinatly be buying one soon.
  • 1 0
 If I didn't need to stop to dial down my fork anyway then and I never stopped moving this would be great. Def looks more xc useful than AM-FR. Still, I'd like one for my wife.

 why is it that I need to pay $300 for this on a mountain bike, but I can find it in any $20 office chair from staples?

 Looks very sleek, maybe when the price comes down i would seriously consider buying one.

 Great, just as I picked up the old version, the new better version comes out.

 This is all well and good, but have they fixed the problems with the Reverb yet? My buddy says if he sits too far back on the saddle, the seatpost won't compress.
  • 1 0
 There was a simple solution to all these height adjustable seatposts in the early 90' was call "HiteRite". No cables, no leaks, less weight, less money, just worked.
  • 1 0
 The 2012 Scott genius' are going to have ridiculously cluttered bars, even with matchmaker: 2 shifters, 2 brakes, travel adjust and seatpost.

 Can I get a setback version? NO! What's the point at zero set back, please Mr.Rock Shox through it back a little.

 You are way off. The current Reverb sells for about $320 at the Calgary Cycle website for example, plus sometimes they have better deals.

 Sorry, $400, not $500 is the retail price for one, calgary cycles aren't selling them at fill retail obviously.

 So will drilling a hole on the downtube void my warranty?
