Photo Essay: Dino Edin Conducts Wind Tunnel Testing with Kirchmann, Woods

For over 66 years, the San Diego Wind Tunnel has helped aircraft, cars, motorcycles, and bicycles, use the wonderful world of physics to help them go faster with less effort. Christopher “Dino” Edin, lead product developer and designer at HED Cycling, is an aerodynamic expert, having helped a vast collection of riders, including former Tour de France champions, become as fast as possible on their bicycles.

The process of wind tunnel tuning is a science, but also an art – it requires incremental, fine adjustments to a rider’s position, as well as the myriad adjustable components of the bicycle – saddle height, stem angle, stack height, and much more. A rider’s comfort also matters – being twisted into a painful pretzel might register low on the drag coefficient readouts, but easy pedaling and breathing equals a relaxed rider, which, usually, equates to speed.

Performance Director Patrick McCarty and Dino accompanied Canadian Time Trial Champion Leah Kirchmann and breakout star Mike Woods to their first visit to the wind tunnel, in order to help them dial in posture and mechanics on the new Diamondback Equipe time trial frame. Their work with one of the cycling’s greatest aerodynamic minds (Dino, no offense Patrick) should help them shave precious seconds of their TT times that can often mean the top step of the podium.

When the wind isn’t blowing, Dino works closely with each rider to tighten up position, posture, mechanics, and comfort on their new Serios bike.




An array of very expensive equipment records a vast amount of information about the rider’s efficiency in the wind during each run.




Like we said, it’s a science, but also an art – Dino ponders adjustments to Kirchmann’s position with the help of dry erase.


HED’s own equipment, including their world renowned JET disc, has been extensively tested in the wind tunnel to become the wheel of choice for some of the world’s fastest riders.






Dino, always a prankster, brought along a little April Fools Joke – is this hulking new glove design is the future of aerodynamics?


Mike Woods, as a former competitive runner and ace climber on the bike, is no stranger to hard aerobic efforts. His time in the tunnel should help him dial in an important facet of the cycling game, aerodynamic positioning.








When not spinning in a stationary position against a huge gust of wind, time in the wind tunnel is a lot like school – the engineers running things have dozens of years of experience in making objects as fast and effort free as possible.
