The company

Velosense was founded in 2017 by Formula One Aerodynamicists John Buckley and Barnaby Garrood

Combining Formula One technology with the very latest in microsensor technology, Velosense have created a device for  measuring a cyclists drag in real-time, in real-world conditions.

The cycling industry - both professional and amateur - is increasingly making use of a wide array of technology and data to improve performance.  Understanding and optimising power output is at the forefront of this, but as yet there has been no accurate or commercial solution to measure wind resistance, which can account for up to 95% of the total power expended by the cyclist.

After three years of development using computational fluid dynamics, wind tunnel testing, and real-world experimentation, a completely novel aerodynamic probe design was created, and Velosense Ltd was formed to take these developments to a commercial market.

The People

Barnaby Garrood and John Buckley have an accumulated 30 years of experience as Formula One aerodynamicists, where they have used wind-tunnel, track, and computation testing methods to refine their designs.  They founded Velosense to  create a new technology in airspeed, wind and atmospheric measurement.

They first worked together designing the front wing for the 2009 Formula 1 world-championship winning Brawn GP car.  Since then they have consulted on a range of projects for motorsport teams and road car manufacturers.

In 2015 Barnaby and John started discussing whether their combined experience could be applied to solve the challenge of measuring real-time aerodynamic drag on bicycles.  After 3 years of development they have patented a unique probe design which enables accurate measurement of wind speed and yaw angles typically encountered by road cyclists.  This accuracy of measurement allows the cyclists' drag coefficient to be resolved with unprecedented precision.


Velosense CdA01



The device

Cycling aerodynamics have specific challenges for which current technology proves inadequate.  Traditional pitot tubes have poor accuracy at the high yaw angles typically seen on bicycles.

Velosense have taken technology used in F1 track testing and adapted it to the specific challenge of cycling aerodynamics to create a completely novel probe design.

The CdA01 is the first unit to embody this innovative design.  Using the very latest in microsensor technology, it measures wind angle, airspeed, and altitude with unparalleled accuracy.  Receiving power meter and speed sensor data through ANT+, the device calculates the drag coefficient in real time and sends the aerodynamic data to the cycling computer through an upcoming ANT+ profile.  Cyclists can then adapt their position and equipment for optimum performance.
