Sometimes a simple video can change our perception of cycling performance. This is exactly what happened at 3bikes when Gilles, a friend of the mag, told ustagis an episode of the podcast " We're going to have another go " titled " Gain Watts without pedaling harder: the Aeroscale method – Manuel Sellier " Intrigued by this bold promise, we decided to take a closer look. And what we discovered goes far beyond a simple technological gimmick. It's a true silent revolution, one that could well redraw the contours of cycling optimization for years to come.

French technology that measures what others ignore
Aeroscale was founded by Manuel Sellier, a former engineer at the French Atomic Energy Commission (CEA), who was passionate about cycling.. In the podcast, he states: “ Today, we put a lot of energy into increasing power... But we still too often neglect what happens between this power developed and the speed obtained. »
In other words: pedaling harder doesn't necessarily make you go faster.. This is by reducing resistance: aerodynamics, friction, wind conditions, slope angle... This is precisely where the F-EXPLORER sensor, Aeroscale's technological heart, comes in.
Mounted on the bike, this little gem analyses all the resistance experienced by the cyclist in real conditions. Unlike wind tunnel protocols, which are cumbersome and often disconnected from the field, here everything is done on the route, in dynamics. And with remarkable precision.
This precision is not the result of chance. According to the information we were able to consult on the official Aeroscale website, the F-EXPLORER sensor integrates very high precision sensors associated with a protocol of test patented field, designed to be easily deployed in real conditions, without the need for a power sensor or complex installations. It allows to rigorously measure not only aerodynamic drag, but also rolling resistance, taking into account wind, air density and the specific characteristics of the routeIn other words, every watt counts, and every piece of data is processed with the aim of providing a faithful image of cycling reality.
Gain watts, without sweating more
Aeroscale's strength lies in its ability to improve performance without requiring additional effort.Yes, you read that right. Several high-level athletes have already benefited from it with concrete results:
- Florian Jouanny, Paralympic handbike champion, gained 100 seconds in an 18km time trial after completely optimising his position and equipment.
- Marion Borras, member of the French track team and European pursuit vice-champion, was able to improve her performance on route thanks to the analysis of her aerodynamics. She notably finished 6th in the French CLM championship in 2022 after precise adjustments to her suit, wheels, and bike.
- Elite rider Anthony Cheytion observed a measured 3% gain in usable power by changing helmets and adjusting his position, all confirmed by Aeroscale sensors.
These performances are not due to overtrainingThey are the result of intelligent adjustment, at the border of science, engineering and biomechanics.
An approach that appeals to all cyclists
The other strength of the method is its democratization.. Manuel Sellier insists in the podcast: “ Our goal is for this technology not to be reserved for professionals. We want amateur triathletes, cyclo-sports enthusiasts, or even just enthusiasts to be able to access it and benefit from the same advantages. »
Aeroscale is now offering sessions of test personalized, mainly around Grenoble, where cyclists can analyze their data in real conditionsThe results help guide very concrete choices: should you change wheels? Adjust the height of the extension? Change your posture? The recommendations are tailor-made.
These sessions are offered at varying levels of depth and budgetA quick 30-minute assessment (DIAG formula, €190) provides a certificate with an aerodynamic efficiency (CxS) and rolling efficiency (Cr) score, along with three priority recommendations. For those who want to go further, the PERF formula at €390 (1 hours) includes several testcomparative tests (up to three configurations). Finally, a full half-day of optimization (PRO package, €890) allows up to twelve testto refine your position or equipment. Customization options are possible (private slot, location outside Grenoble, etc.), with adapted rates.
And the gain can be massive: up to 20 watts recovered simply by optimizing the positionAs a reminder, this can represent several minutes of advancement in a long-distance triathlon event, it seems, according to what we have noted in our readings.
More than a sensor, a philosophy of performance
What Aeroscale offers is not just a tool. It's another way of thinking about performance. We're no longer just trying to push our physiological limits; we're learning to release the energy already available, often limited by small details invisible to the naked eye.
The team is already working with equipment manufacturers to testthe gains of new components (tires, helmets, frames), and the start-up plans to eventually develop a simplified version of the sensor for the general public. This will allow this data to be integrated into training platforms, along with power and heart rate.
In short
The Aeroscale method opens a new chapter in the history of modern cycling. Winning without forcing, by maximizing every watt produced, is now possible — and measurable. All thanks to a 100% French innovation, at once accessible, intelligent, and above all… it seems formidably effective. At 3bikes, we will continue to closely monitor this technology which is clearly moving in the right direction.
