In today’s post we would like to show the effect different positions of your hands have on your aerodynamic drag. Aerodynamics is something very individual and the complete system of rider and bike has to be incorporated, as well as the ability to constantly hold a certain position on your bike. To show this a little better in today’s post we used two different test persons. The calculated CdA values are secondary, since both riders were different in appearance and used different equipment, which was not alternated during the different setups. The time savings or time losses in the three different setups are the important factor which you can achieve by small adaptations or changes. On the pictures you can see the three hand positions we used and the respective times. In the table below, you can compare the results we achieved.
Our test shows that our second test person is significantly slower with Setup 3 while with our first test person this setup was a little faster on double the distance used. This is given to the fact that through the bike setup of test person 2 (handlebars and stem), she had to ride in a not sustainable position and had to perform some corrections to her seating position during the test.
Your take away: With small changes and no financial investment you can gain important minutes. The only way to find out what is the best variation for you is to go out and do our aeroTEST. So, what are you waiting for, get on the bike and test. Stay aero!!!!
