110,000 Data Points from Four Ironman Courses
We collected 110,000 yaw angle and relative velocity measurements by mounting a custom data logger to the front of a bike. We gathered this data on four Ironman courses, and in a variety of riding conditions. Learn more about our Data Collection Process.
Yaw Angles Redefined
After analyzing our data, we learned that a cyclist experiences much shallower angles than we originally thought. We now know a cyclist spends 80% of their time riding between 0 and 10 degrees of yaw. This discovery led us to design the new FLO wheels to be fast at low yaw angles.

Time Savings with FLO Wheels
The below time savings were calculated using our Net Drag Reduction Value (NDRV) equation. The NDRV equation is designed to give cyclists an accurate estimate of expected time savings using FLO wheels. Learn more about our Net Drag Reduction Value equation.
