Narrow tyres, narrow frames and shaved legs will not reduce wind resistance by a noticeable amount at normal cycling speeds. A narrow tyre may reduce road resistance but it will also be less comfortable and more prone to punctures. You will get a far more comfortable ride with a slightly wider slick tyre and you'll be going almost as fast, if that's what you think riding a bike should be all about. I never seemed to have a problem keeping up with the road racer boys around here as I batted along on my ten-speed Claud as long as I wasn't laden with a bagful of sausages and exercise books. A nice, lightweight, responsive frame and a good leather seat obviate the need for all those silly shock absorbers that waste so much energy in up and down motion. And no girly frames that were only invented to preserve the dignity of Edwardian ladies in long skirts. They're hopeless.
