In 2022, the Excursion de France hit its quickest moderate pace of the fashionable generation at a startling 42.03kph. It is hardly ever an outlier, with information throughout Cobbled Classics, multi-day degree races and all collection of historical climbs tumbling lately. Biking is changing into quicker and quicker – a subject which has provoked many vital conversations round protection, but additionally begs the query of why pace has greater, and extra importantly when that pattern might start to decelerate.
Neatly, after finding the most recent technical, physiological and strategic inventions mooted on the global’s biggest biking science convention, it’s no time quickly.
The Science & Biking Convention is a street bike owner’s dream the place the biking global’s biggest brains compile for 2 days of shows, workshops and masterclasses on both the most recent advances at the skilled circuit or throughout the labs.
Aero revolution?
For years, aerodynamic sensors have flirted with a leap forward, the likes of Notio – a spin-off of Argon-18 – utilized by professionals at WorldTour groups and coaches however now not deemed usable sufficient for mass intake. Corporations proceed to paintings on a coaching device that, in idea, will have the similar have an effect on on elite and novice cyclists as energy meters. That comes with the logo who’ve created slightly a buzz lately, UK-based Frame Rocket, whose buyers come with Alex Dowsett.
The Frame Rocket gadget accommodates sensors that connect for your seatpost and handlebars, plus sensor-loaded pedals that change your current pedals. An air-speed sensor could also be integrated that attaches to the entrance of your motorcycle.
In Florence, Frame Rocket’s tech wizard Callum Barnes, or “Einstein”, printed how the gadget might be the person who may just – we repeat, ‘could’ – lay the rules for aerodynamic sensors changing into a using staple.
“We compared drag-force measurements carried out simultaneously in a wind tunnel and the Body Rocket device and, on average, the Body Rocket system agreed within 2.3% of the wind-tunnel data, under different wind speeds, yaw angles and body positions, and reliably detects aerodynamic gains due to positional and equipment changes,” Barnes defined. “As a byproduct of its design, it also enables monitoring of cycling positions, providing valuable feedback otherwise not available to the athlete.”

This obviously was once no impartial find out about – we stay up for impartial research and real-life comments – however there’s a sense that this might – once more, may just – be the only, partially as it’s this type of other aero manner than different efforts in the marketplace.
“The Body Rocket system’s fundamentally different to other aero sensors as it does away with estimations i.e. measuring airspeed and power then back calculating to find drag,” mentioned Barnes. “As a substitute, it immediately measures drag via sensors on the touch issues of the motorcycle offering a a lot more correct drag price and CdA [co-efficient of drag multiplied by frontal area’. This is why the Body Rocket system is the only system where it’s possible to make direct comparisons with that measured in the wind tunnel.”
Barnes also presented a machine-learning project he’s working on. “There’s still work to be done but it’d allow for the user to know what position they are in at every moment in time and when the conditions change, or the athlete is on a different part of the course they can then be notified to change position, optimising themselves live. This shifts the focus from thinking you only have one optimal position to having numerous for different conditions and courses.”
There’s no public deadline for that project. There is for the Body Rocket system, which will be available to consumers from May of this year for £2,950.

While aerodynamics is the easiest area to imagine gains in speed, some of the most pivotal changes in overall rider speed could happen when a bike travels at its very slowest.
“How proficient you are at cornering is vital,” said Uno-X sports scientist Thomas Lagoute. “There are many turns in road races – many of them are 90° or even more – and coaches see them as potentially decisive features in a race. Even less acute turns can be important if they’re positioned before key efforts such as climbs or cobbled sectors. This is due to the accordion effect [a term in physics whereby fluctuations in the motion of a travelling body cause disruptions in the flow of elements following it] and next tactical prerequisites to keep watch over the race.”
To that finish, Lagoute analysed Uno-X rider knowledge via 10 corners at Gent-Wevelgem. By means of GPS and tool knowledge, Lagoute tested nook access and go out pace, the power value of recuperating that misplaced pace and the utmost energy output during the corners.
“Sharp corners have a typical ‘anatomy’,” Lagoute added. “They often result in a reduction in power into the turn and a short but large power surge coming out of the apex that’s well above critical power [i.e. severe intensity domain].
“For half of the riders we investigated, this surge was above their maximal 60-second power. The accumulation of those high-intensity efforts can reduce the ability to mobilise high power at the decisive moment of the race.”

All in all, Lagoute printed, a “low estimate” can be that over 10% of the entire power expended within the ‘red zone’ is related to cornering sections. And that extra skilled riders spent much less time burning via top ranges of power throughout those sections.
What does this imply for professional riders and amateurs alike? “Ultimately, we’re talking about acceleration – the less speed you lose during a corner, the less you have to regain afterward,” mentioned Lagoute. “So, aside from positioning – it’s better to have a clear way to corner efficiently – improving cornering technique’s a must. To that end, having a crack at disciplines like cyclo-cross would be a beneficial exercise.
“Also note that if you’re racing an urban event like a criterium, there’s a tactical trade-off between facing more wind at the front versus the acceleration costs of being out back and correcting the accordion effects after a turn. This might require playing around with to see how you feel in both scenarios.”
Lagoute signed off by means of suggesting that ‘turn analysis’ would develop into extra widespread and must have a look at detailed comments on downhill sections the place method is much more vital. “Further research should also investigate the speed and power patterns of different riders while cornering (loss of speed, smoothness of acceleration, torque/cadence),” he mentioned. “A focus on the physiological variables could also be of interest; in other words, how long does it take to recover from that power spurt.”
How breathing monitoring can strengthen efficiency
Center charge, energy output, coronary heart charge variability, sweat charge, blood glucose… Highway biking in 2025 is metric insanity with, if you select, each and every cellular for your frame below surveillance within the hope of using more potent and longer. So, it sort of feels rather incongruous that the motion you’re arguably maximum acutely aware of when biking – your respiring – stays analysis-free. However which may be set to switch…
Tyme Put on is a US corporate that’s been round since 2014, of which a lot of that duration has been spent running on a sensible blouse. Rounds of funding have observed the attire come to marketplace.
How does it paintings? A sensor tracks respiring charge, respiring quantity and minute air flow, which it might then use to decide a rider’s first (VT1) and moment ventilatory thresholds (VT2) plus their VO2max.
To dig slightly deeper, VT1 is a marker of depth seen in an athlete’s respiring at some extent the place lactate starts to amass within the blood. Because the depth of using cranks up, VT1 is known on the level the place the respiring charge cranks up. You’ll know while you’re at VT1 as you’ll now not be able to speaking with ease.
VT2 is when lactate is impulsively stacking up within the blood and also you’re respiring closely. Now, talking is now not imaginable. VT2’s often referred to as the breathing repayment threshold (RCT) and the onset of blood lactate accumulation (OBLA).

Those are regularly calculated within the lab by the use of respiring equipment to evaluate how arduous your frame is operating and, in the end, create explicit coaching zones for explicit coaching variations. Which, down the road, with constant coaching will make you a quicker, more potent bike owner.
That’s all really well, after all, however how legitimate are the consequences? In line with PhD researcher Giuseppe Greco of the College of Rome, extraordinarily. Greco and his group had six competent street cyclists of their early- to mid-20s, who weighed round 69kg with a VO2max of slightly below 60ml/kg/min, carry out an intermittent workout take a look at and a ramp take a look at, which will increase energy output each and every minute.
The intermittent take a look at consisted of 10 tricky 10-second bursts interspersed with 50-second bouts of restoration. Effort cranked up by means of 10% with each and every burst till they’d reached capability within the ultimate set. The ramp take a look at then began from simply 20 watts with energy output growing by means of 30 watts consistent with minute till the riders had reached exhaustion. Breathing and heart-rate reaction was once measured by the use of each the Tyme Put on sensible blouse and the gold-standard respiring equipment.
What did Greco and his workforce in finding? That the Tyme Put on sensor proved spectacular in opposition to the gold common and higher than heart-rate evaluation. “It detected changes in the body’s response to exercise better than heart rate, which is known for experiencing a lag and is why measuring respiratory frequency is arguably a better marker of physical effort than heart rate,” Greco defined. “Ultimately, these findings suggest that heart-rate monitoring should be complemented by ‘respiratory-frequency monitoring during cycling.
Soupless and the software revolution
Jon Iriberri is one of the world’s most experienced bike fitters. His palmarès goes back 26 years, 16 of which have been working with professional teams. Currently, he’s refining the set-ups of Jonas Vingegaard and Wout van Aert over at Team Visma Lease a Bike, but his wider aim is to help riders of all abilities perfect the art of pedalling.
“That’s why I’ve developed new torque profile analysis software that gives immediate feedback after a training session or race,” the Basque defined. “It easily identifies if there is a pedalling problem and how to amend it.”
Iriberri printed that he beloved Pioneer energy merchandise and their force-monitoring era, each from a coaching and bike-fitting stance. Shimano purchased Pioneer in 2020 and closed it quickly afterwards, that specialize in its personal era. That supposed the disappearance of the force-vector show that many, like Iriberri, noticed as nectar in bettering a bike owner’s pedal stroke.
Now, he’s evolved his personal tool to take uncooked knowledge from energy meters as a way to adopt complicated analytics. Those, he breaks down into a number of spaces across the 360 together with most and medium torque; arch stage (the stage at which the toe is not up to the heel) at 90° most torque; and stability between right- and left-hand energy.
The tool remains to be within the developmental section however, Iriberri predicted, may just lead to a better figuring out of pedalling dynamics and a vital efficiency development. “We could be looking at performance improvements of 7-8% by really focusing on pedal-stroke improvements and the subsequent extra torque,” he mentioned.
For now, Iriberri means that the quickest technique to strengthen your pedal stroke is by means of running on decrease cadence at upper intensities. “If you’re new to regular riding, start at 50-55rpm cadence and reduce it. Any lower to begin with and you could have knee issues,” he mentioned. “Experienced riders can ride at 30-35prm for 10mins without trouble.”
Prime-speed remedy
“Some people are afraid of spiders or snakes. I’m afraid of speed. It’s a phobia.” The phrases of the retired Thibaut Pinot on the 2013 Excursion de France, the place the French hopeful had fallen at the back of the leaders throughout a mountain descent within the Pyrenees. Ever since a significant crash throughout his more youthful years, Pinot struggled on descents.
And he’s now not the one one. All people who’ve suffered a crash, particularly downhill, know that the psychological scars can take a ways longer to heal than the bodily. In the event that they heal in any respect.
How a rider recovers from this type of trauma is an under-researched space, which Carol Royle of Northumberland College in England set about redressing together with her fresh analysis, ‘Investigating Anxiety in Highly Trained and Elite Cyclists.’ (Ok, this one isn’t essentially speed-based however, in our eyes, is extra vital than that because it highlights a not unusual and infrequently mentioned factor.)
“We know that debilitative anxiety exists in highly trained and elite cyclists after crashes,” Royle mentioned. “Cyclists found that having a crash affected their performance times and it also created hesitation in performance.”
That’s why Royle had a bunch of most sensible street cyclists who’d “reported intrusive images of crashes, which continue in the present with the symptoms reaching sub-clinical level”, go through a sequence of digital EMDR remedy periods.

EMDR, or eye motion desensitisation and reprocessing remedy, is a mental remedy that’s been discovered to cut back the indications of post-traumatic pressure dysfunction. It comes to recalling the irritating incident intimately whilst making eye actions, in most cases by means of following the motion of a therapist’s finger. Different strategies might come with the therapist tapping their finger or enjoying sounds. It’s now not transparent precisely how EMDR works, however it’s been confirmed to assist trauma victims alternate the detrimental view they’ve of a irritating revel in.
“The study’s ongoing,” Royle concluded, “but the initial results are promising and intervention has had a ‘treatment effect’.”
May just this be one thing groups roll out sooner or later? Just a little digging came upon cyclists are already the use of EMDR remedy. Former skilled bike owner Imogen Cotter was once interested by a head-on street collision with a van when out on her motorcycle in January 2022. The twist of fate left her with a damaged patella and a displaced fracture in her distal radius, in addition to post-traumatic pressure dysfunction and nervousness. Regardless that she retired in April 2024 bringing up chronic mental trauma from the crash, she printed on the time that she “started properly with a therapist in February of 2024, with a type of therapy called EMDR, which helped me massively”.
The important thing takeaway? EMDR is unquestionably value having a look into if you happen to’re struggling mentally from a crash.
The damaging implications of ever-increasing pace
Royle’s presentation reminded us that with pace and pleasure continuously comes horrendous crashes, like that finally yr’s Excursion of the Basque Nation.
Crashes of that severity have stimulated debate among the UCI and the elite riders round bettering protection. To that finish, at the beginning of January, Wout van Aert and Chris Froome each mentioned gearing measurement restrictions to decelerate the peloton.
“At some point, I think we’re maybe going to have to have the discussion about limiting the progression of technology in the sport to accommodate for the safety aspect,” Froome advised Los angeles Gazzetta dello Recreation. “That could be something as simple as limiting the gears we’re using.”
The UCI’s rules already function plenty of laws designed with protection in thoughts, akin to making helmets obligatory throughout festival and banning the super-tuck using place, followed by means of Froome throughout his heyday.
In our deep dive into how synthetic intelligence (AI) is converting the WorldTour peloton, Steven Latré, head of AI at Imec who is operating with Lotto, advised us, “I know there’s current work looking at AI models to detect certain safety issues along a parcours. There are often crashes in the peloton. Of course, sometimes it’s down to the behaviour of the cyclists, but sometimes it’s down to the design of the route. You’ll be able to pinpoint the potentially dangerous sections with AI.”
Time will inform what protection rules the UCI will enforce, however this is a matter that, slightly rightly, received’t pass away.
