COMPUTATIONAL FLUID DYNAMICS (CFD) > CFD allows aerodynamicists like Chris Yu to play in virtual space with a range of shapes and surfaces, and then simulate the flow of various fluids across those shapes to test their aerodynamic performance. CFD allows you to see, through simulation, things you can’t see in the real world, like tiny ‘bits’ of drag on a frame. It’s an extremely handy way of predicting aero behaviours, discarding designs that are total duds before prototyping, or modifying shapes that have already seen time in the wind tunnel.
SPECIALIZED RACING DATA ACQUISITION SYSTEM (DAQ) > Used on both the road and in the velodrome, the DAQ system takes data—from power, speed, rider position and the direction of wind as it hits a rider—and measures the true coefficient of drag on that rider. Information gleaned from this testing enables us to advise our Body Geometry Fit team, Specialized Racing staff, and the athletes themselves on changes to their position that will improve their performance. While the wind tunnel can be more precise there is nothing more real than riding your bike.
THE WIND TUNNEL > We’ve designed and built the Specialized Wind Tunnel as we dreamed it—to be the perfect, cycling-specific wind tunnel. It’s optimised for real bike speeds and is large enough to allow us to test multiple riders at once, simulating group riding situations. Its proximity to the team enables us to conveniently test things without concern to cost or time, and also gives us the freedom to test everything we make—from a commuting helmet, to apparel, and everything in between. Since it will also be used as an educational facility, there’s room for our SBCU classes to observe testing in progress and learn.
