Light Headwind Tests

Light Headwind Upper-Wheel Fairing Tests

Strong Rider - July 31, 2014

"The faired bike steered more true and felt more connected to both the ground and the rider, while the stock bike felt less stable and was more easily disturbed by the wind. The faired bike was easier to pedal against the headwind, and would be particularly beneficial on longer mostly flat rides."

—Manuel Quiros, Veteran Velodrome Record-Holder

1. Test Summary

The best available data taken on July 31, 2014, indicates that the use of our Upper Wheel Fairings on a typical road bike with a professional rider under light headwind conditions yields gains in average speed exceeding 10 percent (14.5 percent was recorded). (The full report is available for download.)

Power measuring tests in light headwinds were conducted on identical multi-speed road bikes configured with and without wheel fairings. A veteran racer was the rider. Data was recorded using an i-bike Newton power meter.

2. Implications

The results confirm that the use of our Upper Wheel Fairings can significantly increase headwind penetration speeds of a strong rider under light headwind conditions. Gains exceeding ten percent are likely.

Strong Rider - August 14, 2014

1. Test Summary

The best available data taken on August 14, 2014, indicates that the use of our Upper Wheel Fairings on a typical road bike with a strong rider under light-to-moderate headwind conditions yields gains in average speed of more than eight percent. (The full report is available for download.)

Power measuring tests in light-to-moderate headwinds were conducted on identical multi-speed road bikes configured with and without wheel fairings. A young road racer was the rider. Data was recorded using an i-bike Newton power meter.

2. Rider Statement

Brandon Wade is a young Lancaster-based racer who agreed to help with testing of the fairings.

"The faired bike was faster and seemed stable into the headwind. The stock bike was harder to pedal. When I took the faired bike into crosswinds, I noticed that the winds pressed against the bike in a predictable way, allowing for countering with a simple lean of the bike. However, the crosswind did not turn the front wheel as much as on the stock bike, so the faired bike felt more controllable steering in the crosswind. It handled more predictably in the crosswinds than the stock bike. When I road the bike at speed around corners at the intersection, I noticed the increased traction and increased predictability in the front wheel steering. The faired bike was faster around the corner and felt safer as a result."

3. Implications

The results confirm that the use of our Upper Wheel Fairings can significantly increase headwind penetration speeds of a fairly strong rider under light-to-moderate headwind conditions. Gains exceeding five percent are likely for most riders.

Strong Rider - December 4, 2013

"During my first ride with Null Winds Technology Upper Wheel Fairings, the thing I noticed first was an ability to spin whatever gear I was in at a higher cadence, despite the headwind."

—Brandon Wade, December 4, 2013

1. Test Summary

The best available data taken on December 4, 2013, indicates that the use of our Upper Wheel Fairings on a typical road bike with a strong rider under light headwind conditions yields gains in average speed of at least four percent. (The full report is available for download.)

Power measuring tests in light headwinds were conducted on identical multi-speed road bikes configured with and without wheel fairings. A young road racer was the rider. Data was recorded using an i-bike Newton power meter.

2. Rider Statement

Brandon Wade is a young Lancaster-based racer who agreed to help with testing of the fairings. He is currently rated at Cat-5.

"During my first ride with Null Winds Technology Upper Wheel Fairings, the thing I noticed first was an ability to spin whatever gear I was in at a higher cadence, despite the headwind. The second thing I noticed was that after an acceleration, I was able to maintain my pace even against the headwind. It seems that the fairings keep the wheels moving, enabling riders to hold their speed easier despite the headwind."

Novice Rider - December 15, 2013

1. Test Summary

The best available data taken on December 15, 2013, indicates that the use of Upper Wheel Fairings on a typical road bike with a novice rider under light headwind conditions yields gains in average speed exceeding 10 percent (12.5 percent was recorded). (The full report is available for download.)

Power measuring tests in light headwinds were conducted on identical multi-speed road bikes configured with and without wheel fairings. A novice cyclist was the rider. Data was recorded using an i-bike Newton power meter.

2. Implications

The results confirm that the use of our Upper Wheel Fairings can significantly increase headwind penetration speeds of a novice rider under light headwind conditions. Gains exceeding ten percent are likely.
