Kurt, I realize that sliding the axle back is effectively lenghteningthe chainstay. I was merely trying to state this with a bit of politesse... So let's put it this way: if you're bike truly has long chainstays, and if you're going to keep the difference bewtween the chainrings to no more that 10 or 11 teeth, I'd be surprised if you fail to make this work. You probably won't even have to slide the axle back too far. Have fun, Fred Rednor - Arlington, Virginia (USA)
