Reverb Stealth (C1) Dropper Seatpost w/1x Lever

RockShox continues to deliver with redesigns and innovations to dropper post functioning and ranges. The new Reverb Stealth comes in a shorter package to accommodate the ever-changing landscape of seat tube designs, but with longer travel options reaching 175 and 200mm. In addition to expanding fit opportunities for both riders and bikes, RockShox focuses on ease of maintenance to keep you on the trails without hiccups. Featuring the new Vent Valve Technology, fixing that annoying squish in the dropper when air and oil mix, is at-the-finger-tips convenient. Atop the seatpost, a button aptly named “vent valve” depresses, the post compresses, and then you reset and are back on the trail. Air moves back into the air chamber, and the oil stays where it belongs.

For cohesive riding experience, the Reverb 1x lever mirrors SRAM’s shifting style and utilizes hydraulic activation for micro-stepping the seat height with effortless force. And when needing to jam back on the pedals, the post returns quickly to optimal height. The remote extends the hassle-free maintenance ecosystem with Bleeding Edge technology to allow fluid to fill the calipers for a consistent, natural bleed.

  • Updated Reverb accommodates more riders and eases maintenance
  • Deep travel options as well as shorter overall post lengths
  • Vent Valve Technology for separating mixed oil and air
  • Stealth internal routing is onboard for clean lines
  • 1x remote lever keeps adjustments close at hand

The worst product I've ever used.

I've used it several times

The Rockshox Reverb Stealth came stock on my 2020 Santa Cruz Hightower Carbon S and has failed about every 3-5 rides. The hydraulic pressure is faulty leading to a slow actuation which finally gets stuck at maximum travel. It was bled 8 times and finally sent in for warranty inspection which took 1.5 months. The dropper failed again on the second ride after it was sent in for repair/replacement. The most dangerous experience was when it failed to go down before a jump. It caused a severe seat impact to my groin and abdomen (nearly a liability). It is a completely failed product! I have spent over $120 on repairs to the dropper without success. Santa Cruz, do not put this on your amazing bikes, it has ruined over half my rides since May 2020!!!

So smooth!

I love this post! The lever action is light and smooth. You can very easily control the speed of return by how much you push the lever in. Super easy install with the stealthamajig quick connect. There is almost no side to side movement of the saddle. Have had this post for 18 months and haven’t had a single issue. No worries with fraying and contamination of an old school cable, since it’s fully sealed hydraulic.


How much does it weight?

Can't believe rockshox had the balls to

I've put it through the wringer

Literally non functional. Bought one at the end of the summer and have had issues on literally every third ride. Like the seat post gets completely stuck in one position kind of issues. Already had to have it bled 4 times in 3 months. I can't beleive that any company would be willing to put their name on this shit.


I completely agree, this piece of junk came on my Santacruz Chameleon 27.5.. 8 months later, with very little use, it won't go down, great bike, but garbage dropper post! Rockshox should be ashamed!!
