Thanks guys, it seems Sram say no but general consensus seems to be that its possible, I currently have XT shifters so seems like Im getting into murkier waters here, might stick it on the classifieds and buy Xtr mech instead, thanks everyone for your input, its really appreciated.
city link,pah sold my rockhopper on the 29th collected on the 30th for next day delivery, still hasnt arrived, they cant even tell me where it is, apparently they have a 60,000 parcel backlog to work through, is that even possible?
