We zijn niet geïnteresseerd in loze marketingslogans: Voor ons is 'aero' ook echt 'everything'. Deze filosofie zit verwoven in alle producten die we maken, en heeft als resultaat dat we constant de allersnelste producten ter wereld weten te maken.


Aero is Everything

Aerodynamische weerstand is de grootste kracht die een fietser treft. De enige manier om deze kracht volledig te elimineren, is om te stoppen met bewegen; niet echt een goede optie. Daarom hebben we kosten noch moeite gespaard om een ​​team van aerodynamische experts samen te brengen en ze alle tools te geven waarom ze vroegen om de klus te klaren: Computational Fluid Dynamics (CFD), on-bike Data Acquisition (DAQ) en het bouwen van een eigen Win Tunnel aan de overkant van ons hoofdkantoor in Morgan Hill, Californië.

Chris Yu, Mark Cote, Chris D'Aluisio, Camron Piper, en Chuck Teixeira - ons team van getalenteerde ingenieurs heeft samen meer dan vijftig jaar aerodynamische ervaring en ruim 20.000 uur in windtunnels doorgebracht. Hun expertise en aanwezigheid vormt een sleutelcomponent in het verder ontwikkelen van onze vooruitstrevende producten. Immers, wanneer we iets in windtunnel willen testen, hoeven we enkel de straat over te steken. Deze totale vrijheid heeft een cultuur van innovatie gekweekt die je nergens anders in de fietsindustrie zult tegenkomen.


The Win Tunnel

Of course, the lynchpin to our whole aero operation is our very own Win Tunnel. Designed and built to our own exacting standards, it's the world's finest cycling-specific wind tunnel. We optimized it for real bike speeds, and it's large enough to allow us to test multiple riders at once, simulating group situations, like the peloton or a team time trial. Its proximity to the team enables us to conveniently test things without concern to cost or time, so we have the freedom to test everything that we make—from a commuting helmet, to clothing, and everything in between. And since it's also used as an educational facility, there’s room for our fitters and retailers to observe and learn from testing, which directly impacts product development and your experience in the local bike shop.

The FreeFoil Shape Library

Surprisingly, our quest for perfect tube shapes don't always start in the Win Tunnel. With the latest Venge, we started with a new piece of technology that we call the FreeFoil Shape Library. Our engineers wrote an optimization algorithm and utilized a supercomputer (yes, we used an actual supercomputer) to help create new airfoil shapes with different weights, surface areas, and structural targets. Armed with this library of shapes, all with different aspect ratios, we were able to plug them into the different parts of the bike and test a variety of configurations to determine the fastest setup in the Win Tunnel. And moving forward, this methodology is being applied to nearly all of our bikes and components. So, with a little help from some Silicon Valley supercomputing, we're discovering the new shapes of speed.

Computational Fluid Dynamics (CFD)

We're not alone in our usage of CFD, which allows aerodynamicists, like Chris Yu, to play in a virtual space with a range of shapes and surfaces. With it, he can easily simulate the flow of various fluids across shapes of his choosing to test their aerodynamic performance. CFD allows us to see, via 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 behaviors. Where our usage diverges from the norm, however, is that we're able to discard designs that are total duds before developing prototypes for testing in our Win Tunnel. Of course, we're in a unique position, in that, we're able to design and test in CFD in the morning, 3D-print a prototype in the afternoon, and test in the Win Tunnel before the day is done.

Data Acquisition (DAQ)

Then there's our own DAQ system. Used on both the road and the velodrome, DAQ takes data from power, speed, rider position, and the direction of wind, and it measures the true coefficient of aerodynamic drag on the rider. Information gleaned from this testing enables us to advise our Body Geometry Fit team, racing staff, and the athletes themselves on changes to their position that'll improve performance. And while the Win Tunnel can certainly be more precise, there's nothing quite like combining what we learn there with real-world riding.
