I see Eden has already recommended the "Training for Time Trials" thread

And she has also given you the best advice regarding the most useful piece of equipment that will give you the biggest improvement with no extra effort - aero bars.

The bigger you are, the more wind resistance you present, therefore the more of a difference aero bars will make.

For me, aero bars made nearly 2kph difference. For my friend, shorter and more petite than me, they make just on a 1kph difference.

Enjoy
