I had a fox transfer dropper post (2024) on my specialized epic Evo and this dropper would stick periodically even though it wasn't that old and weathered. I could have gotten a One Up, Wolf tooth, PNW but decided to bite the bullet and get the RockShox AXS as I had the previous model on my other bike. Such a game changer! Easy to install and integrates well with the SRAM APP as I have the transmission derailleur. You do need to buy a dropper post remote though. I got the SRAM pod (left side) and you can configure this on the SRAM APP as well. I'm loving this axs dropper post!
