Well, Let me lay it down for you, I'm new to bikes basically, I can ride em and what not, but not too great a fixing them.

Okay so, My chain decided to break on me. I have a 5 speed Roadmaster mountain bike from like, Walmart.. I can't really afford a whole new bike and it was a good bike until this happened, I suppose I was just peddling too hard and the chain was old. It has a uh... shimano system? Anyways, I measured out the chain and it came to ABOUT 53 1/4th inches, Just over 53 inches anyways. And I have no clue what size chain or anything to get to replace it, There is no fixing the chain I had, It just died, we'll leave it at that.

Okay, enough rambling, main details - 5 speed Roadmaster 26" Mountain bike. 53 inch chain, and I need to know what kind of chain I need to get, and where I can find a chain breaker too, any help would be greatly appreciated!
