Features
Your smart trainer becomes a virtual wind tunnel
Measure, adjust and control your aero position to save watts and gain speed — for triathlon, Ironman or solo efforts. Real-time frontal area and drag analysis with just a webcam. An innovative, complementary alternative to Zwift, MyWhoosh and Kinomap.
Built to make you faster
Our Mission: Democratize aerodynamics
Our Promise: See it, measure it, feel aero
Why add aerodynamics to your training?
Every watt counts — and so does your budget.
Gain 1 to 5 km/h with no extra effort
See, in real time, how many km/h your position is costing you. +1 km/h at 25 km/h; up to +5 km/h at 45 km/h. Better than a €5000 bike.
We’ll show you the numbers…
From 25 km/h, air eats ~70 % of your power (up to 95 % at 45). Shrink frontal area, get speed back. Elbows in, head low, narrow bars — AeroX shows the gains as you move.
👉 Finish rides getting home faster without pushing harder — slicing through air. That’s performance and fun.

Gain real speed, not virtual power
On a trainer you progress in a virtual world. With AeroX, you save 40 W — and get faster outside.

Smart trainers push you to chase power — great for virtual fun. Outside, you’re not always faster, and aero may feel awkward. That’s 40 W lost. Real-time aero feedback both optimizes your position and turns it into a habit, so you enjoy outdoor rides and perform when it counts.
Train like a pro — without an elite budget
Pros master power, heart rate… and aero. A wind tunnel? From €1500. AeroX brings the same lever to your smart trainer — with just a webcam.
Understand how pros train…
Classic plans cover power and HR. But TT champions also hold power in optimal aero. Testing aero is out of reach for 99 % of riders (wind tunnels, velodromes, sensors). AeroX changes that: real-time position data from home training.
👉 What pros pay thousands for, you can now use at home — with that feeling: “I’m training like them.”

Ride faster without spending thousands
90 % of aero drag is your position — not bike, wheels or helmet. Learn to optimize it for less than aero socks.

Deep wheels, high-end frames, fancy helmets… marketing sells a few watts for thousands of euros. In reality, your body creates most of the drag. The best bike won’t fix a position you can’t hold for 5 minutes. Invest where it pays: your position. Your top-end gear deserves top-end training.
AeroX really works
I gained +3 km/h — from 36 to 39 km/h — on a 2008 €700 bike. No new bike needed.
I’ll tell you everything…
While building AeroX, I learned to hold aero from 25 km/h: narrower aerobars, longer posture, head and shoulders low. Even uphill, once speed passed 25, I stayed aero. Result: 36 → 39 km/h on a 2008 €700 bike, same FTP. I used to get dropped on the flat — not anymore. None of it without real-time feedback. — Olivier D., triathlete, AeroX founder

FAQs
Answers to your questions
Frequently asked questions
Why AeroX?
Learn more…
From 25 km/h, aerodynamics is 70–95% of what slows you down. Without data, we just push harder. AeroX shows other, smarter levers. After that, you won’t be able to say: I didn’t know.
What gear do I need?
A computer, your smart trainer, a camera
A smart trainer (Bluetooth FTMS), your bike, a computer (macOS or Windows) and a webcam — laptop cam, smartphone or USB webcam.
How long does setup take?
In under 2 minutes, your trainer becomes a virtual wind tunnel…
Place the camera, calibrate in two clicks — you’re ready for real-time aero feedback.
Is my trainer or sensor compatible with AeroX?
Compatible with 95% of smart trainers — probably yours…
Yes. AeroX works with most smart trainers (Wahoo, Elite, Tacx, Saris, etc.). macOS and Windows available now; tablets in development. If your trainer isn’t interactive, use analysis mode (visual feedback without resistance control).
Innovation or gadget?
Learn more…
Built by a CNRS researcher and triathlete, AeroX gives you concrete aero feedback — like HR monitors did 20 years ago. Training without HR or power sensors seems unthinkable today. Tomorrow, add aero.
I ride in a bunch — is this still useful?
Yes — unless you plan to stay at the back!
Cycling isn’t just sitting in the bunch. Echelons, breakaways, pulling — aero makes the difference. With +3 km/h, you might enjoy attacking.
Do I need a subscription to find and test my optimal position?
Test with the free plan, progress with a subscription
You can test on day one, free. The subscription turns that position into a solid habit — your sixth sense outdoors.
I’m already used to an aero position — is this still useful?
Learn more…
Being “in position” isn’t enough. Effectiveness matters. AeroX makes invisible details visible: head too high, elbows too wide… fix them with instant feedback.
