RockShox Reverb Review

Components Pro Reviews

This infinitely adjustable seatpost is stupendous, with a silky-smooth stroke, and because of its unique hydraulically controlled remote handlebar lever, it has an easy to operate action, and simple installation. I abused the seatpost for four months, on every imaginable terrain possible, and it has been through rain and snow storms, had sand and dirt tossed at it, and has preformed flawlessly, which is helped fabulously by the custom sealing system.


RockShox Reverb
The Reverb uses an air, oil and spring design for 125mm of infinite seat height adjustment, and is available in two lengths, 380mm and 420mm, as well as two diameters, 30.9mm and 31.6mm. The air spring and fluid are separated by an IFP (internal floating piston), and it uses a snug fitting triple-lipped energized sealing system for protection. The shaft and head are both made with forged 7050 aluminum alloy, and it uses three brass keys within the collar to keep the lateral twisting at a minimum. The zero offset saddle clamp uses the industry standard 2-bolt attachment system, which offers easy adjustment of tilt, and fore-and-aft placement of the saddle. The Xloc hydraulically actuated remote, which uses 2 wt. suspension fluid, is available in a right or left hand version, and can be pared with SRAM shifters and Avid brakes using their MatchMaker X clamp, or with just the discreet mount. The remote has a speed control adjuster nicknamed the “The Slap or Tickle,” which controls the height return speed.

Measured Spec (31.6mm x 380mm):

  • Weight – 544 grams (includes remote)
  • Length – 127mm stroke, 380mm

Installation
What immediately sets this adjustable seatpost apart from the competition is the ease of installation. Insert the post into the seat tube, adjust it to the required height, clamp the saddle into place, fiddle with the hydraulic hose routing along the top tube, and attach the remote on the desired side of the handlebars. I installed the remote on the left side, and used the MatchMaker X clamp with SRAM shifters, which was sort of annoyance getting set properly. After those simple steps, the seatpost can be used without any tuning required, although the hose may require shortening, depending on the bikes set up and geometry, and the routing that was used. I ran it long for a couple of weeks and didn’t have any issues (I was lazy), but I did get tired of the large loops, and so I went about remedying it. To shorten the hose, put the speed adjuster in the slowest setting, and using a sharp utility knife, slowly cut a slit into the line about a 10mm long (don’t cut or scratch the barb), and grasp with a pair of pliers and pull the line off. Cut the hose to the desired length, and push it onto the barb, and using pliers twist it into place. Refer to the SRAM “How to shorten the remote hose” video for detailed instructions. It worked perfect after the shortening, and didn’t require any bleeding.

    Some of us ride in the winter. No hydro post review is complete until you know its reliability in temps 45* and less.

    What is up with the roadie saddle?

    How does it compare to the Specialized Black Lite post?

  • trailbrain says:

    I’m actually surprised you got 4 months out of it. Mine lasted 6 rides then failed…wouldn’t hold air.

  • Brian Mullin says:

    You know I am a closet roadie? I just started to test the new BlackLite seatpost. It’s a much nicer design, as the remote cable installation is very straight forward and easy to perform, and it has a quick-release (the cable end piece pop’s out of its seatpost holder) to make removal simple. I like it so far, as it return is lightning quick, and less things to worry about since its a mechanical system. Review out soon!

    As much as I would never ride without an adjustable post again my Reverb has come with its share of problems. In nearly 12 months it’s gone back to the distributor three times. Once to get the hose and button replaced (under warranty), once to get the button replaced (result of a crash) and another because it couldn’t hold air, not exactly sure what they did, can only assume change the seals (under warranty). As good as they are is as bad as they are.

    If you found it “Viscous – even on fastest speed setting” than it should be bleeded definitely.
    Mine didn’t work at all out of the box.

    My Reverb lasted one ride before the barb on the seatpost snapped. Rockshox sent me a new hose kit with an improved strain relief design that look more like what is on my Avid Elixr disc brakes. I haven’t had any problems yet with ~250 miles of hard riding.

    I will try and get them to send me a bleed kit and the new barb!
