You can find them cheaper if you look around for bikes that have been damaged and those parts are still ok. As far as the chain set up goes you can buy a 520 or 530 chain, I would recommend x-ring. Would need to know that before you buy anything else, because you would need to by the rear sprocket (Vortex) and front sprocket (PBI i believe, but i may be wrong) accordingly. EBR idler pulley or a free spirits idler pulley. EBR idler wheel if you go with their idler pulley with the spacer. A press of some sort to install the spacer into the idler wheel. I know some sites have kits you can buy and that makes it easier rather than piecing it together. cant remember off the top of my head though who has them. Buying the kit would save you a lot of trouble.
