Ok guys you have to forgive me. I'm new at this. I would like to replace my wife's 10 speeds cables there original and a little rust. I'm just unsure how to buy these. How does it come? Is there a tool to crimp on new ends on the outer cable cover part. I need to know how you do this? and what to buy. This is an old miyata 10 speed from the early 90's So they should be replaced. It nice for her it's her older childhood bike. So I'm happy to fix it up for her.
