The drive for extra knowledge in pursuit of sporting excellence marches on. In biking phrases, riders have been accessing energy numbers and monitoring coronary heart charges for a very long time. So recent floor has been sought; this week we spotlight a “drag power measurement system’ that permits riders to coach to aero with no wind tunnel and a physique temperature sensor that is all the trend within the WorldTour.
On the subject of aerodynamic optimizations, we’ve got been doing our very personal subject testing too, taking to the Silverstone Sport Engineering Hub wind tunnel to see simply how a lot quicker tremendous slender handlebars actually are.
We have additionally acquired some extra conventional merchandise on present, however each with a twist – wheels that weigh beneath 1000g a pair and a race match biking jersey that is designed for each women and men to put on.
The World’s costliest turbo coach
So what precisely is the World’s costliest turbo coach? Properly, you have to excuse our slight tongue-in-cheek title right here – as a result of it is really a wind tunnel. Situated simply outdoors the historic Silverstone Circuit, you will discover the Silverstone Sport Engineering Hub, which is residence to a world-leading sports-specific wind tunnel, designed with cyclists in thoughts.
Why am I calling this the world’s costliest turbo coach you ask? Properly, as a result of it kind of is! The rolling street, designed for cyclists, really contains a energy meter, full with erg mode, and a fairly reasonable journey really feel, so theoretically, you possibly can perform structured coaching classes on this machine simply as you’d on a sensible coach – this one simply prices over 2 million kilos and occurs to have relatively good air flow…

Anyhow, the explanation I used to be there, was to check handlebar widths – extra particularly, the rising development in direction of tremendous slender handlebars. We examined a baseline 420mm handlebar, alongside a 320mm and even an excessive 260mm (UCI authorized) setup. At present, the outcomes are nonetheless being processed by the engineers operating the exams, however we could have a full characteristic breakdown on this matter within the coming weeks, and spoiler alert, I believe we shall be seeing a big uptake in tremendous slender handlebars within the subsequent 12 months – you heard it right here first.
Whereas we anticipate these outcomes, I felt it to be a superb time for me to supply some residence truths about wind tunnel testing, as a result of it is not straightforward! It was my first time in a wind tunnel, and I wasn’t fairly ready for simply how a lot psychological focus the method takes. Check runs solely totaled about 2-5 minutes every, however I needed to preserve a wonderfully nonetheless physique place in every take a look at, keeping track of elbow, head, and saddle place markers, all of the whereas preserving my cadence and wheel pace equivalent for every run.
Despite the fact that the street was set to a forgiving 150 watts, this was nonetheless a troublesome night. The method was made simpler by Mike Twelves, who was in control of conducting the exams. We communicated via a radio which meant a second pair of eyes might be solid over my physique place always, and he may inform me to maintain my head up or down to make sure high-quality knowledge was captured.
I did my finest to remain as nonetheless as potential via our take a look at runs, and ultimately, it was all worthwhile, with a number of promising knowledge for us to look via – keep tuned for the total outcomes!
Scope Artech wheel vary

The place will we begin with the brand new Artech wheels? The claimed sub-1000g weight for the climbing version? Or that the deep part aero mannequin that’s stated to solely weigh about 300g extra? Possibly it’s the character impressed patent pending rim know-how that’s the actual headliner?
Definitely the Dutch model has packed lots of tech and speaking factors into its newest vary of wheels. The road up consists of Highway, All-Highway, Gravel and Triathlon variations, every with completely different inner rim widths and with the Gravel rim being hookless. Each the Highway and All-Highway are then provided in three rim depths: 22mm, 45mm and 65mm. Remarkably, the claimed weight for the 22mm Highway wheelset is simply 965g.

However, as talked about, maybe essentially the most attention-grabbing ingredient of the wheels is the Aeroscales know-how used on the rim floor. Scope’s designers turned to the pure world because it appeared to seek out methods to cut back aerodynamic drag, extra particularly fish scales. Its analysis highlighted how a part of a fish’s capability to maneuver so successfully via water is because of the form and association of its scales. Utilized to a wheel rim, Scope says the patterned floor helps to generate velocity streaks, which journey at completely different speeds over the rim floor; these assist to stabilise the airflow, which in flip reduces drag. To check the speculation, Scope examined rims with out and with out the scales and the latter proved to be considerably extra aerodynamic.
There’s loads extra happening, too. The hub shells are 3D printed from Scalmolly, an alloy favoured by each System One and the aerospace business. The spokes are each carbon and have an aero design. The ratchet is created from titanium relatively than metal to assist decrease the load. Naturally all this tech goodness is mirrored within the value of the wheels, with the fashions retailing at $4,398 / £3,498.
Santini Unisex Ombra Jersey

Unisex clothes is nothing new. However can a biking jersey, particularly one which guarantees a efficiency match, actually be designed to accommodate each women and men cyclists “indistinctly” whereas “making certain an optimum match”? Santini believes so.
The unisex Ombra jersey is the latest results of the Italian model’s long-standing partnership with Polartec, which specializes within the manufacturing of premium efficiency materials. Within the case of the Ombra it’s a mix of Polartec Energy Stretch that stretches 4 methods and is claimed to by no means lose its authentic form and Polartec Delta, used for the facet panels, that’s stated to be fast-drying and environment friendly at wicking sweat. On prime of this the jersey affords licensed UPF30+ UV safety.

It’s arduous to not be no less than a little bit sceptical right here. Santini says the Energy Stretch cloth “expands the boundaries” of stretch materials to “make sure the jersey matches completely to the physique”. However which physique is it actually speaking about? Professional bike owner? Athletic amateurs with single digit physique fats? Or the remainder of us, male or feminine, who are available in many fantastic sizes and shapes?
We’re going to be placing the Ombra jersey via its paces, so watch this house to see the way it performs for each our female and male take a look at riders.
Physique Rocket’s street bike prototype

We’ve adopted the event of Physique Rocket, the world’s ‘first and solely’ real-team aerodynamic drag power measurement system, with curiosity. And now the group has unveiled its first street bike prototype.
Why is that this attention-grabbing? The system, which makes use of a variety of wi-fi power sensors located on the rider contact factors alongside an ‘out entrance’ mounted airspeed sensor, was initially focussed on time trial and long-distance triathlon disciplines – and constructed across the requisite TT bikes. Now it’s working with considered one of its associate athletes, reigning Olympic triathlon champion, Kristian Blummenfelt, forward of the Paris Video games this summer season.

Provided that street bikes are used within the Olympic triathlon, Physique Rocket have geared up Blummenfelt’s Large Propel with a brand new system, permitting him to get pleasure from many hours of ‘coaching to aero’ forward of the Olympics, with out the expense and disruption of wind tunnel testing. It contains a customized prototype stem that Physique Rocket says accommodates the identical tech as its TT aerobar sensor. The brand new system additionally contains a sensor that’s appropriate with the Propel built-in seatpost and the corporate’s newest airspeed sensor. The pedals sensors and bottle cage-mounted receiver field keep the identical.

Physique Rocket Founder Eric DeGolier says that designing a street bike system was all the time the plan and that newer UCI rule modifications impacting a rider’s aerodynamics have made it extra related than ever.
“With the latest modifications to handlebar and brake lever guidelines, and the brand new slender bars made to handle it, there’s a lot to study,” he says “and with this new prototype, no one could have as a lot time to study as Kristian.”
Core’s physique temperature sensor
(Picture credit score: CORE)
It’s protected to say that WorldTour groups have a tendency to go away no stone unturned within the pursuit of positive aspects and glory. Proof of that is discovered within the widespread use of Core’s physique temperature sensors. The model has simply introduced official partnerships with 10 groups, together with BORA – hansgrohe, Soudal-Quickstep and Movistar, as properly issuing a further 150 sensors to UCI riders. It estimates that some two-thirds of the professional peloton are utilizing the sensors, which simply strap to the riders chest, to assist them higher perceive how their our bodies reply to warmth.
So what does this wearable do? In line with Core it “offers customers with real-time knowledge by measuring core physique temperature, pores and skin temperature, warmth pressure index, and warmth pressure rating”.
The info is then utilized by groups to develop methods to how finest deal with the results of warmth throughout racing. Core additionally offers its personal evaluation for the groups, offering what it describes as ‘round the clock’ suggestions and suggestions all through the season; one such product of this collaboration is the group’s testing of the thermoregulation properties of the rider’s clothes.
Core additionally stresses that the sensor and app are additionally helpful for “non-professional athletes who merely wish to perceive how their physique reacts to thermal stress and methods to enhance their sporting efficiency”. A sensor and chest strap will set you again just below £250 or simply over $300.
