I need new shocks for my bike. at the moment i've got rst launch forks and they dont move at all so i was thinking about getting some new shocks. I ride a diamondback compression 1 and i do dirt jumping downhill and a bit of xc. i was thinking about getting dirt jumper 3 or rock shock argyles the only problem is i'm on a buget. what sort of price should i be paying for the shocks?
