Hello, I'm new here, and was hoping that one of you (or more) could perhaps help steer me in the right direction. I'm having some problems with my gear shift. While cruising in gear (It doesn't matter which gear) every eight or ten turns of the pedal, or so, it feels as though the chain slips, and for an instant, the pedal falls through abit, without propelling my bike any further. When I flipped my bike, and spun the pedals, I noticed that every time the slip occured, my rear derailer would lurch back abit, and then snap back into place. Does anybody have any ideas as to what's afflicting my Huffy, and if so, perhaps any possible solutions to my problem? Any response is appreciated. Thanks for your time.
