I have a Huffy Cruiser. When I brought it, it was a seven speed. Now it is a ten speed, with two sprockets in the front (53 & 40) and five in the back (14 to 28). Now it is time to replace my chain. I am asking someone with experience in such matters: would it be acceptable to get a replacement chain with the same kind or would I be better off with a chain designed for a five speed? I do have problems adjusting the shifting. I either have correct chain stop for the large gear and not the small one or the reverse. Since I have the shifting levers that do not click, I just do it by feel. While I am thinking about it, since I went from a 46 teeth front crank to a 52/40, should I get a longer chain? Any advice would be appreciated.
