If all of the potentially-competent cyclists actually rode in a competent manner, it would be a lot easier for these other cyclists to pick up on how it should be done.
IM grumpy old bastard O, the "Lance boom" has resulted in too many new cyclists for the old guard to educate. The result is entire clubs full of cyclists who don't know what they're doing, don't know that they don't know what they're doing, and so are unwittingly reinforcing each other's incompetence -- to the point that any "outsiders" who mention that they don't actually need to fall over quite so often are seen as enemies.
I don't know what to do about this, except to hope that Lance's retirement and Landis' antics will send the boomers back to the racquetball courts.
