I have come to the conclusion that I need new chain and sprocket kit for my bike. I was wondering what everyone seems to be running and the results of the products. I was looking at some some supersprox but can't decide. I want something that looks pretty cool but I want the rear sprocket to be black I think. When I'm riding my bike at a steady rpm it seems to jerk. And I think it may be because my chain is stretched and I had to re-tighten in twice in the last 2 weeks. It seems like when I have it on a stand I get the chain to the proper tension and then rotate the rear wheel a 1/4 turn then it's loose then another 1/4 turn then back when I set it at. Idk but it's starting to annoy me. Any input would be greatly appreciated but I just want to replace it all I think.
