The point of doing this conversion was not to say that, "horizontal drop outs are bad." Quite to the contrary, my brother and I have both ridden converted road bikes extensively. The fact is, he did struggle to get the chain properly tensioned before. Our aim was to solve that issue and we did it simply because we could.

Please don't take offense or think anyone is try to negate the validity of the various styles of drop outs. As I've said, I ride a road bike now and am not all interested in arguing about the merits of the different frame designs. I posted this merely to share something fun that my brother and I did together and to show that indeed, it CAN be done. No one is saying that anyone SHOULD do it.
