Introduced with the Rockshox 2020 lineup, the MegNeg upgrade kit allows you to tune your shock exactly to your ride. The MegNeg air can allows more mid-stroke support, a plusher initial feeling and more bottom-out force while using less tokens; all thanks to an even larger negative volume. Since the MegNeg is empty of spacers, you'll see more negative air space, which helps reduce the amount of force it takes to get into your bike's travel.
