French startup Aeroscale has launched its \u201cworld\u2011first sensors and patented analysis technology,\u201d designed to measure aerodynamic drag,\u00a0rolling resistance and drivetrain efficiency\u00a0in real-world conditions\u00a0across all cycling disciplines. The system is already in use at WorldTour level, and its consumer device called Wasted Watts is expected to be made available to buy\u00a0in November.<\/strong><\/p>\n

Over the past few decades, the abundance of power meters<\/a> and cycling computers<\/a> has transformed both professional and amateur cycling, but the quest for data doesn\u2019t stop there.<\/p>\n

Last year, several companies experimented with live drag measuring devices, such as the <\/a>Body Rocket System<\/a>\u00a0which is a\u00a0device that fits onto your bike and streams\u00a0real-time aerodynamic drag data\u00a0directly to a Garmin head unit.\u00a0Now, French startup Aeroscale is stepping into the arena, promising to \u201crevolutionise\u00a0cyclists\u2019 performance by tracking the slightest waste of watts.\u201d<\/p>\n

Like Body Rocket, Aeroscale\u2019s technology aims to measure aerodynamic drag (CdA) and rolling resistance (Crr)\u00a0without the need to spend a fortune on wind tunnel sessions.\u00a0<\/p>\n

“Thanks to\u00a0world-unique sensors and patented analysis technology, Aeroscale evaluates in just a few minutes all the friction forces acting on the cyclist: aerodynamics, rolling resistance, drivetrain efficiency”, the company says. “Unlike lab-based solutions (wind tunnels, drum benches, etc.), Aeroscale\u2019s technology quantifies energy losses directly on open roads, under real race conditions, and in record time.”<\/p>\n

Currently, Aeroscale has released the\u00a0F-Explorer field test device, which measures both rolling resistance and air resistance using its proprietary technology. It says that the system is being used by\u00a0“most” French World Tour teams, the French women\u2019s national road team, and numerous\u00a0para-athletes. We got in touch with some of those teams to confirm if this was the case, and received\u00a0swift replies from\u00a0both Decathlon AG2R La Mondiale\u00a0and Groupama-FDJ. The former simply confirmed they are working with Aeroscale, and Groupama’s press officer said they worked with them last year, and potentially will again\u00a0later in 2025: “They are serious people that work very well”, he added.\u00a0<\/p>\n

Later this year, the company plans to release\u00a0Wasted Watts, a consumer version designed to provide real-time tracking, making the technology more accessible to non-professional cyclists.<\/p>\n

\u201cOur mission is to make the invisible visible: the hidden losses that cost you performance. We want to give every cyclist access to optimisation tools that were once reserved for the elite\u201d, explains Manuel Sellier, founder of Aeroscale.<\/p>\n

How does Wasted Watts\u00a0calculate its figures?<\/p>\n

Wasted Watts combines\u00a0proprietary sensors\u00a0with\u00a0advanced modelling algorithms\u00a0to measure energy losses in real time, delivering live feedback on watts lost to friction within just a few seconds, according to the brand.\u00a0<\/p>\n

However, unlike Body Rocket\u2019s system, which you attach, ride, and leave to gather data as you go, Wasted Watts appears to require a dedicated testing setup. Images of the system show riders passing through a start zone to trigger measurements, suggesting it\u2019s not a fit-and-forget device, but one designed for structured testing sessions.<\/p>\n
