Physique Rocket, the aero tech start-up recognized for its real-time aerodynamic drag drive measurement system for cyclists and triathletes, has revealed a street bike prototype, which may maybe – if it enters wider manufacturing – make wind tunnels altogether pointless for all however the very high elite cyclists.
Whereas Physique Rocket has beforehand labored predominantly on TT and triathlon bikes, the brand new prototype brings the tech to drop bar bikes. Bringing the built-in CdA (coefficient of aerodynamic drag) measurement system to bikes with out aero bars coincides with the method of the Paris 2024 Olympics, the place Physique Rocket athlete accomplice and reigning Olympic triathlon champion, Kristian Blummenfelt, is gearing as much as defend his title.
However why is the system so distinctive? Nicely, only a few of us can afford to lease out a wind tunnel, and beforehand these have been the go-to resolution for exact aerodynamic measurement. Physique Rocket, in essence, goals to offer you related perception into how aero you’re with out the price, and with information that’s private to you.
That stated, Physique Rocket is not the one model dabbling with real-time drag measurements. We have beforehand lined Canadian bike model Argon18’s Notio which hit manufacturing in 2019, Velocomp AeroPod which Dave and Mat put to check in the identical yr, after which there’s Aerosensor, which additionally efficiently entered manufacturing and is now in the stores.
With that, it is protected to say that the marketplace for real-time CdA measuring gadgets appears to be booming, it is all attributable to their sensible nature and talent to deal with one thing a wind tunnel won’t ever be capable to present.
“Once we have been designing this, we had to take a look at the actual downside right here. The issue is that the rider may be very completely different from what a wind tunnel is designed for—we’re all formed otherwise and alter once we are using,” Eric DeGolier, Physique Rocket’s founder, instructed us once we first lined the model’s aero tech.

The newly unveiled prototype integrates seamlessly with street bikes, a departure from Physique Rocket’s earlier deal with time trial and long-distance triathlon sectors. In case you’ve got missed it beforehand, this is how the system works in brief.
To get the measurements, Physique Rocket contains sensors in your seat publish, stem and pedals. Actual-time aerodynamic drag drive information from these is then despatched wirelessly to a Garmin biking pc, offering real-time suggestions throughout your experience. This information may be very useful as you’ll be able to see the impression of various positions, actions and equipment whilst you experience in real-life situations.

After the experience, the AI-driven evaluation software program guides you thru the method and helps them observe their progress over time, with out the necessity so that you can turn into an aero professional, Physique Rocket says.
With solely street bikes allowed within the draft-legal Olympic triathlon, Physique Rocket wished to develop a system that’d assist Blummenfelt good his aero tuck on drop bars too., so the model has outfitted not less than certainly one of Blummenfelt’s Big Propel bikes with the brand new system. It options custom-designed elements reminiscent of a prototype stem housing the identical know-how as its aerobar sensors designed for time trials.
The prototype integrates seamlessly with the Propel’s built-in seatpost, and retains the unique pedal sensors and a bottle cage-mounted receiver field.
“Aerodynamics is important in each self-discipline of biking, and street bikes have all the time been a part of our plan. With the current adjustments to handlebar and brake lever guidelines, and the brand new slim bars made to deal with it, there’s a lot to study, and with this new prototype, no person can have as a lot time to study as Kristian,” stated DeGolier.
Coinciding with the prototype announcement, Physique Rocket has additionally launched its newest funding spherical on Crowdcube. In 2021, the model stated it is aiming to launch quickly, nevertheless it appears we’ll want to attend a bit of longer. Again then, the model stated the unit value for the system was to be round £1,499 to £1,999, together with an influence meter.
