I want to change the current spring (450x2.5-79kg) to a 350 spring.
Problem is I don't know which of the 2 Roco tstr shocks I got, cause on the website there is one with 200mm, and one with 215mm?

Have you tried calling Marzocchi with with model and bike specs? That's what I would suggest, might save you some time/energy. Good luck!
