My chain is pretty old, i need a new one, what is the best website to buy this from. I am also wondering, What kind of tire i should buy? I need a new rear tire and i ride alot of medium, soft, and a tiny bit of sand riding, mostly mid, not super hard but suometimes i ride super hard terrain too. What tire? I have a 14" rear tire. I was also wondering should i get the sprocket and chain combo? I have had my rear sprocket for over 4 years and it looks like i may need a new one, the edges are getting a bit rounded, and my chain sags on the bottom of the rear srpocket it when it is tight. Thank you for the help
