need some help please
Hello, a friend of mine gave me a Diamondback bike which needs a back rim, & a piece on the back rim that says "shimano sis megarange" I don't know much about it except it looks really bent out of shape, also the rim thats warped says, "avenir 26X1.5 36h" could someone please tell me how to purchase what I need? I've googled & ebayed & cannot find what I need. Please help me... I'm trying to do something about my weight problem.
You might be better off taking the bike to a local shop, and have them replace the needed parts. You could do the work yourself, but by the time you buy the tools you'll need, it might not end up being any cheaper...
Based on your lack of experience with bike mechanics I also recommend a trip to a decent local bike shop (NOT K-Mart, Dicks, Wal-Mart, etc.) to get what you need done properly.
