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 e...
