On leg-burning climbs, crazy fast descents and rolling technical terrain, RockShox's Reverb Stealth dropper post enables you to attack the trails like never before. Just hit the hydraulic remote lever for 5-inches of infinitely adjustable up-and-down saddle movement without ever slowing down! The return speed is easily adjustable by turning a dial on the remote while the triple-lipped sealing system and sealed hydraulic hose keep dirt out for clean, consistent operation. There's also an included collar that limits travel to a preferred height setting. This Stealth routing keeps your cables nice and neat, too. Never lose your flow again.
