FLO Cycling Combined Aero Drag and Rolling Resistance Study

Power Watts vs. DEGREES OF YAW

DEGREES YAW

* Bike Speed 35km/h or 21.75mph

* Wheel load 45kg or 99.21lbs

* Rolling resistance numbers were measured on a Mavic Open Pro wheel at 120 psi with Vittoria or Challenge latex inner tubes.

* Beta correction of data completed.

* Beta correction calculation assumes that the ambient wind is at 90deg to the direction of travel (pure crosswind) for the resultant yaw angle for a given bike speed.

* Tires marked with a Strikethrough have not yet been roller tested.

* All roller testing performed by Tom Anhalt from Blather 'bout Bikes. Thanks Tom!
