What is Photogrammetry?
Photogrammetry is taking a bunch of photographs of a person, and then stitching them into a 3D mesh. So, a friend would take pics from all angles of you in your aero position on your bike, somewhere between 30 to 100 photos. Predator’s software turns those into a virtual 3D object, which they use to design the handlebars.
Before and after comparison of Williams’ basic aerobars versus the Predator custom model. Presumably they took his beard into the CFD calculations, too.
The fun part of all this is that it’s literally just the tip of the iceberg of what they’re working on. For Williams, they scanned his entire body and are simulating full body, arm, and even hand gesture positions, and even predicting common movements, to optimize every facet of your aerodynamics.
Predator founder Aram Goganian says that, over the lifetime of an athlete, they’ll get faster in the wind tunnel, but it takes years. That’s because each wind tunnel session might only check 10 to 30 positions. Even if you did 10 sessions per year, that’s at most 300 positions. With their new technology, they can simulate thousands of positions overnight.
Once the optimum positions are identified, the ideal hand and arm positions are used to create aero bars and extensions that also take the handlebars and other equipment into consideration, plus wind conditions, the rider’s average speed, and other criteria (which Aram says is a computational nightmare). The outcome is a cockpit that creates the most aerodynamic rider-plus-bike system.
The base price for the bars, using photogrammetry to create the custom shape, is $1,795.
If you want the CFD optimization to refine the shapes further to optimize more of your body position, that’ll add an additional $1,000 for the starter package. And it can go up from there depending on how advanced you want to get.
