Trek, I only caught it because I've been on weekly calls with them the last month.

KabyMom, you need to ride as many bikes as you can to help you determine what type of of geometry and handling you like. Standover is not the only thing you're looking for. Reach and drop are critical. Reach or cockpit length is the length of the top tube + the bar + stem + hoods = the distance from the saddle to where you grip the bar hoods. Women frequently (but not always) take a shorter reach than men because many of us have short torsos compared to our legs.

Drop is the distance from the top of the saddle to the top of the bars. The higher your bars are the less aggressive the position. If you look at the Pro Peloton you will see that their bars are very low. If you look at ultra distance riders, they'll usually have the bars higher. It is a factor of comfort and aerodynamics.

You can search the forum for all kinds of discussion on road bike fit. It is a frequent topic.
