Don't judge.

The old saw about not judging books by their covers has never been truer than for the RockShox Reverb Stealth (B1) Dropper Seatpost. On its face, it looks reassuringly similar to the Reverb we've all been abusing for years; however, peel back the cover and you'll find a very different beast. The big news is that it now ships with travel-specific post lengths and it's available in a wider range of travel options. With the current crop of more versatile all-mountain machines, those expanded travel options mean that even tall riders will have the range to cover XC speed and enduro descents.

The Reverb's story has been completely rewritten, including redesigned internals and updated travel options. The post's got a new host of SKF internal seals, and repositioned bushings help deal with the issue of slacker seat tubes occasionally thwarting the action of the old Reverb. The latest model features overlapping bushings that not only smooth the post's travel on enduro machines, but also increase that smoothness' longevity. It's not so smooth that it results in undo give though, so you won't suffer any mushiness from the post jogging 5mm under impact.

Despite those updates, the cable routing that sets the Reverb Stealth apart remains unchanged. By routing the cable through the seat tube, rather than off of the head of the seatpost, RockShox eliminated the large cable loop found with most dropper posts, including the standard Reverb. Attaching the actuator cable to the head of the seatpost creates a loop of excess housing, which requires careful cable placement to keep that loop away from tires and suspension linkages. The Stealth solves this problem by running the cable through a hole in your frame. Many modern frames are built with "Stealth" routing holes already installed, and older models are typically able to be modified for fitment by a qualified bicycle mechanic.

The hydraulic actuator system also returns virtually unchanged. When we first heard that the Reverb employed a hydraulic remote, we were dismayed at the thought of bleeding a seatpost. However, the Reverb has proven to be so smooth and reliable that its hydraulic remote has come to be one of our favorite features. And while the competition's cable actuated posts seem simpler on the surface, clumsy levers and gummed-up cables have made us thankful for the Reverb's buttery, push-button actuation, and the reworked internals mean that we'll be enjoying that action for much longer.

  • 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

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).

    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...

    Keep us up to date on reliability. I'm about to pull the trigger on the Thompson Elite covert, but if the RS has gotten better, I'd like to go with it.

    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.
