With the new, friction-reducing DebonAir air spring, the current forks and dampers respond more sensitively and smoothly than ever before in the history of RockShox. It offers you maximum traction under all conceivable conditions. An optimally adjusted chamber volume always leaves your fork high in the spring travel and thus creates trust and safety even for the most difficult descent.
With this upgrade kit you can upgrade your Lyrik / Yari A1 + from the 2016 model year to the 2021 level of Rock Shox technology.
