BIKE CDA/ FIELD AERO TESTING
Shave 10–50 Watts in One Afternoon
Service Description
Want faster bike splits without throwing more money at gear? Our Outdoor Aero Testing Session delivers real‑world watt savings you can feel on race day. What Happens The first 10-20minutes of the first ever session are used to get a baseline. For testers user this is not necessary. During each out and back ride we check live CdA readings from an aero sensor mounted on your bike and your power meter (loaner available). With every test and changes we make, we calculate CdA changes, and time/wattage gain for your specific goals. How much can you get done? Should you book for one, two, or three hours? One test is roughly 15minutes of riding, retesting is a good way to confirm data when big changes in CdA are made. With every test, we should only aim to make one modification, introduce one change A new helmet for example, or different placement of bottle, or hand placement etc. Recommended time frame examples A/B test, or 3 simple changes after having done previous baseline: 1hour 3-6 changes (simple bike configuration adjustments, and some simple changes): 2 hours 4-10 changes (multiple retests, replacing bike parts, or many small changes): 3 hours Typical Results Riders typically finish the session "10–50 W more aerodynamic", worth roughly 10-20 minutes shaved off the 180 km Ironman bike leg. Gains apply to non‑draft triathletes, breakaway‑minded roadies, and podium hunters alike. Discounted retests keep you improving as your gear evolves. Bring Your bike, race kit, and power meter (we can supply one if needed). Book Now—ride smarter, not harder, and turn free speed into podium places. ------ Coach note: A top‑tier rear disc wheel like the Zipp Super‑9 sells for ≈ $3 000 and, even in the brand’s own data, trims ~3 minutes over a 180 km Ironman bike leg. That’s about $1 000 per minute saved—roughly 40 × the cost per minute of this aero‑testing session (≈ $25/min saved). Meanwhile wind tunnel testing cost about 1000$ per 2hours.
