Re: Twin Sprockets
I've been toying with this very concept for several weeks. My problem is frame width too. I've already built a sliding chain tensioner that would (manually) guide the chain from one sprocket to the other. I couldn't keep the chain from hitting the chainstay on the outer sprocket and I didn't want to skin up the paint with an experiment. I'm going over to a guys house this afternoon to look at his collection of old bikes. If I can find what I'm looking for, an old cruiser with fat tires, I'll buy it, if it has a wide stance in the chainstay area. My bike is just too skinny, like its owner, for the double sprocket idea. Maybe a fatter bike. I'll keep you posted.
