The latest version of Rockshox's 35mm air spring is a subtle but significant upgrade offering a noticeable difference in performance. With a 10mm taller seal head, the spring lives higher in the stanchion allowing air to move from the positive to the negative air chamber. That small chance allows the fork to sit much higher in it's travel. For $42 and a bit of time in the shop, this is one of the cheapest high performance upgrade you can give your fork!
Compatible with (2016+) Lyrik/Yari A1+, (2018+) Pike B1+ / Revelation A1+
