The RockShox ZEB Ultimate RC2 DebonAir Boost 27.5" suspension fork in 38 mm with maximum adjustment options

The ZEB Ultimate DebonAir Boost suspension fork by RockShox for 27.5" wheels with a new 38mm chassis offers best adjustment options thanks to Charger 2.1 RC2 shocks. The Charger 2.1 RC2 shock allows you to independently adjust high speed and low speed compression stages. With a stanchion tube diameter of 38 mm, the suspension fork delivers better performance and increased stiffness and safety. The optimised DebonAir suspension responds really softly, is adjustable using bottomless tokens and won't let you down on rough terrain. The ZEB carries the same genes as the Lyrik and BoXXer and is perfectly suited for enduro use with its large travel.
