My family is obsessed with cycling and I'm finally getting in on the action. I set aside my hybrid and am riding a road bike for the first time in my life, clip-ins and the whole nine yards. I am so unstable on it though; it's always a little scary when I first get going. But my biggest problem is that I am wibbling and wobbling all over the place. I'm not even close to biking in a straight line.

How do I, consciously and physically, ride in a straight line?
