    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

    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.

      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).

      The only actual "game changer"

      • Familiarity: I've put it through the wringer

      People call things game changers all the time. To me, this is one of the few products that actually really changed how mountain biking works for me. Less stopping, more fun. Droppers are now a mandatory part of any trail bike. It's unfortunate because they are so painfully expensive, but I have never once regretted the investment.

      Update on this, I did have to bleed this thing to get it working well. It was moving very slowly at first. The good news is that they include in the package EVERYTHING needed including fluid, so it just took me a few minutes to watch a youtube video then 5-10 minutes for the actual work and I was on my way.

      Great

      • Familiarity: I've used it several times

      New internals seem to feel a little more precise. The most noticeable difference besides the graphics is the wider range of adjustability for return speed. Long term reliability is still up in the air, we shall see...

      Awesome

      • Familiarity: I've used it several times

      After spending last season on a KS cable-run dropper post I'm really glad I went with the Reverb for this year. As much as I cringe thinking about another component to bleed, the hydraulic system is simply easier to install and better performing.

      By routing the hose from the seat tube and out of the top tube you can easily determine your desired hose length. Just route the hose, set the post to desired height and wa-lah. My cable-run dropper last year involved tons of guesswork in cutting correct housing/cable length. Additionally, one of the pitfalls of the cable-run systems is their reliance on cable-tension. If you decide to move your trigger, your post, your housing gets bumped, anything effecting cable tension.. guess what? Your dropper won't work. I was constantly pulling on the housing last year mid-ride to keep the cable taught.

      Out on the trail the post moves buttery smooth through the travel. The trigger is consistent and positioned to make using it a breeze. So far I'm really happy with this dropper.
