That's exactly why I believe one should not have a problem supporting the road bike with one's toes
without getting out of the saddle. (Yes, I understand that some people might naturally have trouble pivoting their foot sufficiently.)
Mountain bikes with their higher BB location is a different story. (Assuming that they are normally set up for a straight leg. Are they?)
