I was looking for the parts I need on some web sites and got confused. There seems to be a lot of info I need.

Will any 9 speed chain work for my 9 speed bike? is there other specs that I need to know?

As far as cables go. How do the ends get put on at the shifter side of the cable? Am I better off buying housings and cables and ends separately or am I better off getting a kit?

If I do buy separately, what are all the parts That I will need to get a full cable replacement done.

thanks
