I know I probably should not upgrade my Schwinn, but I have had it for a year and a half, got it from Walmart and no problems.
I want to upgrade the parts on this the bottom bracket, the cranks and the rear derailleur, but I'm not sure what parts are compatible and what is better than the parts that are on it.
I think it has a Shimano Tourney set, but I want to upgrade this to use it as a learning experience. I want to learn how to put certain parts on, so if a problem ever does arise, then I know what to do. But it is a great bike.
People have said that Schwinns suck. I got this for my birthday and it is amazing, but with better parts it can be better. So if anyone has some links to parts that can go on this, post them.
