The RockShox Reverb Dropper Post with external hose routing is compatible with frames that aren't designed to be used with an internally routed dropper seatpost. The RockShox Reverb with the left side mounted remote places the button on the top of the bar when mounted on the left side of the bar and under the bar on the right side with RockShox low-force hydraulic actuation. Valving on Reverb B1 has been sped up over the A2 version with the return rate of the slowest setting on the B1 being as fast as the fastest setting on the A2. RockShox also uses increased bushing overlap an improved internals on the Reverb B1 for improved reliability and longer service intervals.
