well.. the 4.0 that came on my sx trail is getting a bit old, and i'm tired of not having any adjustments, but now i cant find any 9.0 X 2.75 roccos or dhx's for sale anywhere on the web.. i guess sx trails must have a kind of oddball rear shock? i have seen pictures of them with roocos and other shocks but are thoes a diffrent size that till works? or does anyone know where i can find one the right size? thanks a lot!!!
