The drive for extra information 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 drive measurement system’ that enables riders to coach to aero and not using a wind tunnel and a physique temperature sensor that is all the fashion within the WorldTour.
On the subject of aerodynamic optimizations, we’ve 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 received some extra conventional merchandise on present, however each with a twist – wheels that weigh below 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 should 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 may discover the Silverstone Sport Engineering Hub, which is house 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 type of is! The rolling highway, designed for cyclists, really includes a energy meter, full with erg mode, and a reasonably life like experience really feel, so theoretically, you might 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 rationale I used to be there, was to check handlebar widths – extra particularly, the rising development in the 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 working the assessments, however we can have a full function breakdown on this matter within the coming weeks, and spoiler alert, I feel we will likely 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 great time for me to supply some house truths about wind tunnel testing, as a result of it isn’t simple! 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. Take a look at 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 protecting my cadence and wheel pace an identical for every run.
Despite the fact that the highway was set to a forgiving 150 watts, this was nonetheless a troublesome night. The method was made simpler by Mike Twelves, who was in command of conducting the assessments. We communicated by a radio which meant a second pair of eyes might be forged over my physique place always, and he might inform me to maintain my head up or down to make sure high-quality information was captured.
I did my greatest to remain as nonetheless as attainable by our take a look at runs, and ultimately, it was all worthwhile, with a number of promising information for us to look by – keep tuned for the complete outcomes!
Scope Artech wheel vary

The place can 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 expertise that’s the true headliner?
Actually the Dutch model has packed a number 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 supplied 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 probably the most attention-grabbing factor of the wheels is the Aeroscales expertise used on the rim floor. Scope’s designers turned to the pure world because it regarded to search out methods to scale back aerodynamic drag, extra particularly fish scales. Its analysis highlighted how a part of a fish’s skill to maneuver so successfully by 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 idea, Scope examined rims with out and with out the scales and the latter proved to be considerably extra aerodynamic.
There’s loads extra occurring, too. The hub shells are 3D printed from Scalmolly, an alloy favoured by each Formulation 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 worth 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 “guaranteeing 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 alleged to by no means lose its unique form and Polartec Delta, used for the aspect panels, that’s stated to be fast-drying and environment friendly at wicking sweat. On prime of this the jersey presents licensed UPF30+ UV safety.

It’s exhausting to not be at the very least a little bit sceptical right here. Santini says the Energy Stretch material “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 by 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 highway bike prototype

We’ve adopted the event of Physique Rocket, the world’s ‘first and solely’ real-team aerodynamic drag drive measurement system, with curiosity. And now the crew has unveiled its first highway bike prototype.
Why is that this attention-grabbing? The system, which makes use of a variety of wi-fi drive 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 one in every of its associate athletes, reigning Olympic triathlon champion, Kristian Blummenfelt, forward of the Paris Video games this summer season.

On condition that highway bikes are used within the Olympic triathlon, Physique Rocket have outfitted 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 includes a customized prototype stem that Physique Rocket says comprises the identical tech as its TT aerobar sensor. The brand new system additionally includes 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 highway bike system was at all times the plan and that newer UCI rule adjustments impacting a rider’s aerodynamics have made it extra related than ever.
“With the latest adjustments to handlebar and brake lever guidelines, and the brand new slender bars made to deal with it, there’s a lot to be taught,” he says “and with this new prototype, no person can have as a lot time to be taught as Kristian.”
Core’s physique temperature sensor

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 nicely 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 accordance with Core it “offers customers with real-time information 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 greatest address the consequences of warmth throughout racing. Core additionally offers its personal evaluation for the groups, offering what it describes as ‘round the clock’ suggestions and proposals all through the season; one such product of this collaboration is the crew’s testing of the thermoregulation properties of the rider’s clothes.
Core additionally stresses that the sensor and app are additionally useful for “non-professional athletes who merely wish to perceive how their physique reacts to thermal stress and enhance their sporting efficiency”. A sensor and chest strap will set you again slightly below £250 or simply over $300.
