OK, Just to start I am very new to biking and i'm clueless to say the least. My bike sit in a storage building for about a year and a half with no maintence, no riding. I finally brought it back from home and when I went to shift it will only shift like one gear up and two down from where it was. After some work the chainrings(hope thats right) will all shift now, but the back won't. Any ideas?
Also, what kind of lube do I need to use on the derailurs and everything besides the chain. As a matter of fact, whats good for the chain?
