Rockshox Deluxe RT3 DebonAir rear air shock. 190x42.5mm stroke
It would have come spec'd on a 2019 Stumpjumper ST Expert.
I had a base model 2019 ST and my shock blew out so Specialized sent me this one free.
I never used it and it's been wrapped since I got it. I bought another shock before they sent this and it's just been laying around as a spare.
