The Specialized Bicycles team is in their wind tunnel again for another test. This time they are testing the fastest way to descend a hill on a road bike.
Specifically, they are testing the most aerodynamic positions to descend and what kind of differences these actually make.
The first test is a regular position with the rider's hands in the drops. The second position has the rider keep his hands near the stem. The last position is what many professionals use, sitting on the top tube with hands near the stem.
Although the last position is technically the "fastest" I can't recommend anyone use this position, especially while on group rides. This position can be incredibly dangerous.
I hope you enjoy!
