hey im in the midst of building up my first bike, and this might be a dumb question but if i buy the 1/8" kmc s-10 stainless steel chain, do i need any other parts or connectors or anything? or does it come with the "master link". if its the wrong length for my bike can the bike shop take links out and stuff to make it fit? i'd assume so but i want to make sure before i order stuff. im gonna be using 46x17 gearing
