    Don't judge.

    Don’t make the mistake of thinking the Rock Shox Reverb Stealth (B1) Dropper Seatpost has been sitting comfortably for all of these years, content to rely on its name and impressive legacy rather than change with the times. While you’ve been barreling through rock gardens and earning a few new scars on your old Reverb, RockShox has been quietly overhauling the Reverb Stealth’s design. This year, it unleashes some serious changes like travel-specific post lengths and a wider range of squish options to bring it up to speed with the discipline-bending enduro monsters multiplying by the day on the trails.

    The expanded post lengths and travel options are good news for taller riders who find the range offered by traditional lengths to be slightly lacking on either end of the spectrum. RockShox didn’t just adjust sizing for taller riders, though. Gleaming new internals stand at the ready inside the seatpost, complete with SKF internal seals keeping the grit out as well as rearranged bushings. The repositioned bushings mean that slacker seatposts won’t interrupt travel anymore, and you’ll experience a smooth glide, rather than a jump, every time you engage the remote.

    RockShox couldn’t find room to improve the already impressive cable routing on the Reverb, and the clean design remains reassuringly unchanged for this model. Free of excess cables and complicated fitting, the Stealth’s cable runs subtly through the internal seatpost routing space most modern frames are now built with, but a mechanic can adapt an older frame by carefully drilling a hole. Mount the hydraulic actuator on either side of the bars, and in exchange for a few regular bleedings, you’ll enjoy supple actuation ride after ride.

    • Iconic dropper post features improved enduro functionality
    • Increased travel and size range accommodates taller riders
    • Refreshed internals work better with slack geometry
    • Stealth routing provides clean, hassle-free integration
    • Enjoy smooth, precise adjustments with hydraulic actuation

    Expensive and becoming even MORE so

    • Familiarity: I've put it through the wringer

    Coming up on my second winter with this post and not looking forward to it. The plunger is wholly NOT ergonomically correct and cannot be made better by adjusting the position of it. Yeah, I feel bad having to shell-out another Hundred bucks for the lever that it should have come with; but, on longer rides when your hands begin to cramp, that plunger just continues to get worse and worse. That said, it works great on shorter rides (under 2 hours) in the heat of summer! And I like the way it snaps / clicks when it tops out, letting you know that it has returned to the full-up position. In the winter however, when your hands get fatigued and cold, forget it! Because the hydraulic oil gets more viscus as the mercury drops, that plunger gets even harder to actuate. So, I bought the lever.

    The post comes with 5 weight oil which was a disaster last winter. I live in Texas, so I have enjoyed riding year round, only last winter was my first with this post. We all know that the temperature drops as we climb and somewhere around 45 degrees F the post gets stuck in the down position, because the oil becomes too thick to move anymore. This even happened to me in Crested Butte, CO in July, when it rained at around 11,000 feet and the temps plummeted. I decided to do a total rebuild on the post, installing both 2.5 weight oil and the one-by, lever-style actuator. I will update this after I have given it the proper amount of testing / riding in a variety of temperatures and altitudes. Fingers-crossed!

    High maintenance

    • Familiarity: I've put it through the wringer

    I've had this post for a little over a year now and it works really well when it works. The downside is over the last year it has had to been rebuilt three times. the hydraulic system in it is very finicky. Probably going to look into a different option next time it happens. Having it rebuilt is very expensive.

    POS remote and hydraulic bleeding

    • Familiarity: I've used it several times

    Disappointing! The remote is a shitty push button that mounts on the top of the bar. If you're like 99% of the Mountain bike world, you probably want a shifter orientation, mounted under the left hand bar. In order to get a similar shifter orientation, you have to buy the right handed remote and mount it upside down on the left hand side. WTF? Stupid. Then the use of hydraulic instead of cable is another bonehead option. I'm forced to use it with my Wreckoning frame but I'm seriously thinking about going the Shim route and going back to a real dropper post 9point8 is the best I've ever used.

    Great rebound

    • Familiarity: I've used it several times

    The Reverb Stealth B1 has been great so far. The is my second Reverb and it seems smoother than the prior generation. It’s rebound is great and it doesn’t have any sagging. I never had issues with my first Reverb so I’m cautiously optimistic with the newer model.

    3 for now

    • Familiarity: I've put it through the wringer

    This will be the second RockShox Reverb that I've worked with up to now and the first one was solid through about the first 1,000 miles when the bottom O-Ring failed and dumped hydraulic fluid into the bottom bracket area of the frame I was running at the time.

    I've seen that a few internal changes have been made on the B1 version for better or for worse. I've heard of there being less internal problems occurring over time for these changes and that has yet to be seen and while it has worked pretty well so far it doesn't seem to have the return or collapse speed like the previous version. Also, since there is a 1x remote out now from SRAM (which looks awesome) the previous remote just needs to get phased out as I can place it well but the plunger type shape is cumbersome.

    Will try to get the 1x remote eventually when it is released on its own for improvement and keep an eye on the internals but OK so far..

    Poor reliability

    • Familiarity: I've put it through the wringer

    I've had two of these posts. One had worked, the other stopped functioning after a couple of months. SRAM would not fix under warranty stating the lever must have been damaged in a fall (interesting, there's no scratches on it to support their claim), so also not impressed with customer support. There's other dropper posts out there, such as Thomson that have given me better reliability.

    The B1 seems solid so far

    • Familiarity: I've put it through the wringer

    I've owned multiple first generation Reverb Stealth posts and I had issues with one of those posts "sagging" in the extended position.

    On my more recent mountain bike purchases I've gone with this 2nd generation Reverb, the B1. It has improved seals and better reliability. So far I've had no issues with this version. At one point it started to get a little slow to return and thought I may have felt some "sagging" in the travel, but I bled the post and made sure the air pressure was at 250lbs. psi and it was back to working like brand new. It does not seem to have the same problems my original Reverb did.

    Critical advice:

    Store your bike with the dropper post extended

    Never pick up your bike by the saddle if the dropper post is compressed.

    When the dropper post is compressed, especially the Reverb, there is a lot of pressure on the internal floating piston and seals. The two measures above will prolong the life of seals and the IFP.

    Problems after 5 months

    • Familiarity: I've put it through the wringer

    Seat post (b1) started seizing on a ride in an awkward position.
    Noticed some minor scratches on it, may be contributing, not sure yet. Bled it last night and everything seemed great again, but today after a ride it became really slow again to pop up. Will update after LBS looks at it tomorrow. Maybe have 60-80 hours on it.

    Also I have the 170mm, really need a 200mm at 6'5".

    Simple an smooth

    • Familiarity: I've put it through the wringer

    The new improvements to the Reverb might not be notable on first glance, but the stiffer and more durable post will show why the changes were made over time. Loving mine so far. I appreciate that these come with the bleed kit for home maintenance.

    game changer

    • Familiarity: I've put it through the wringer

    If you dont have one, you need to get one. If you ride bikes trails all the time this will make the ups to downs and the downs to ups a breeze. i've had multiple reverbs and have yet to have a bad one and I take it through the paces.

    Love it!

      Coming from a Specialized Command post, I love my Reverb! It's smooth and very consistent - you always know how it will work. I know some people have complained about its reliability, but after using mine consistently since March, I've had zero issues. I should note I have the original Reverb. The newer B1 model should be even better.

      Awesome Dropper

      • Familiarity: I've used it several times

      Love this dropper! I've only had it for a couple of months, so long-term results are TBD, but as of now it's been super solid and responsive.

      great now, long term reliability TBD

      • Familiarity: I've used it several times

      I threw out my last Reverb because it needed a full rebuild including the top cap, which was quoted at $250, and the videos online to show how to do it were nearly an hour long. I had it for 2 years with no services others than bleeding. This one feels a bit smoother, the install / bleed kit is nice, but only time will tell if it holds up and at the point if it is easy to rebuild as something like the LEV (which is as easy as it gets)

      This dropper rocks!!!!

      • Familiarity: I've used it several times

      On my second reverb and it never disappoints. No hesitation when dropping for downhills or making the seat higher for brutal climbs.. The controls are simple and perfectly placed. Love this dropper!

      Smoother/More Reliable Previous Reverb

      • Familiarity: I've put it through the wringer

      The Reverb B1 functions smoother and is more reliable than the last generation. The only complaint I have is that the lever can sometimes snag baggy shorts, if they offered a shifter style lever it may help.

      150mm is sick

      • Familiarity: I've put it through the wringer

      It's nice having a full 150mm of drop on my V1 Bronson. Hopefully it's more reliable then the 125mm that came on the bike stock, 3 failures on that one over the years (warrantied 2 of those times).
