i'm totally new to cycling, i bought a giant scr1 bike and it's a total pleasure to ride. i'd like to look after it as it cost me to much not to. the confusing thing is what oil should i use to keep my bike in shape. do i need different kinds of oil for different parts of the bike? i won't be taking it apart or anything, just oiling the bits i can see.i'd like something that doesn't turn everything into a black mess. forgive my ignorance like i said i'm a total novice. and a girl so i don't know much about these things!!!! can anyone help
