The two biggest problems facing women's racing are aggressiveness and coaching. I found that the two biggest differences between men's and women's racing was aggressiveness and rate of tactical development. Men tend to want to attack their brains out without thinking and develop tactically more slowly while developing physically more quickly. Women tend to race much less aggressively and think their way through the race.
Women develop tactically faster and physically more slowly.
I managed to teach my women to race as aggressively as my men while learning to use complex team tactics and it was incredible. They took home more than half of the wins and more than half the top six placing. The coaching problem began with the bike boom of the early 70's. There was a sudden increase in the number of racers to the point that most beginning racers didn't have the opportunity to learn from experienced racers. Suddenly there were huge packs of category 3 and 4 riders who didn't have a clue about bike racing and team tactics.
