Rockshox Trek Deluxe Re:Aktiv 230x57.5mm Rear Shock - Remedy/Slash in good condition with very few marks or scratches plus the shock hasn’t had much use . It is also all fully functional as it should be so will be good to go straight out of the box plus the mounting screws for the rocker link are included aswell .The shock comes with special trek mounting hardware that means it will only fit a trek bike the bottom mount is 40mm and the top mount is 54mm . Please ask if you have any questions.
