Rockshox product ambassador Greg Herbold let “slip” that Rockshox is working on a stealth version of the Reverb hydraulically actuated drop seat post for 2013. Trek and Scott are reportedly on board to spec it on one or more models. (shown above is a regular version with the hose out in the open)
The Reverb Stealth will flip the internals to put the valving and controls on the bottom, letting the hose run out the bottom of the post and through the frame. Unless you’re willing to drill holes in your frame like HB, it’ll require a frame made to run it internally. The benefit is a much cleaner looking bike and less chance of snagging the hose.
