Aerodynamics have been within the information once more this week with Visma | Lease a Bike’s new time trial helmet, the Giro Aerohead 2.0. It induced fairly a stir on Monday when the rider’s of the Dutch group used it in Tirreno-Adriatico’s stage 1 time trial. This provides us the chance to look again at Ed Hood’s tackle the aerodynamic query a couple of years in the past.

“I’m by no means happier than once I’m writing.”
~ Ed Hood, as spoken to Martin Williamson from the passenger seat, driving alongside a stage route on the Tour de France.
Pricey Readers – Our beloved colleague and pal Ed Hood suffered a severe stroke in February. We don’t count on Ed will make it again into our bunch, so we’ve began a GoFundMe web page to assist Ed along with his future. Learn the complete publish right here – and please think about donating.

We’ll be posting a collection of Ed’s work from the previous 16 years, as a result of nice story-telling by no means will get outdated.
Ed’s rant: The UCI has introduced that they are going to be taking a look at harmful behaviour in a peloton, together with adopting harmful positions on the bike; descending on the highest tube. Ed Hood takes a take a look at descending, handlebars and aerodynamics generally.
No extra ‘pet canine’
‘The UCI Administration Committee additionally determined to strengthen the regulation regarding doubtlessly harmful conduct of riders, together with throwing a bottle onto the highway or throughout the peloton (which can pose a hazard for following riders), and taking on harmful positions on the bike (particularly sitting on the highest tube).’
Not a great look
So, the place which ‘The Froome Canine,’ employed to show that he might really look worse on a motorcycle than he normally did has been banned. In his case, no loss, I might hardly bear to look at him, he appeared so ungainly – however I’ve to confess that watching the likes of Matej Mohorič undertake it was fairly spectacular.
Mohorič – Spectacular
Wind tunnel assessments would point out that other than being damned uncomfortable and troublesome to keep up, the aero benefit is negligible. Some are in favour of the place, arguing that it’s spectacular to look at, provides curiosity to the game and nobody has crashed while using it. Critics would add the phrase, ‘but’ to the top of that sentence and endorse the UCi stance.
Pantani – off the again
However ‘rad’. Descending positions are nothing new, bear in mind the late Marco Pantani’s, ‘bum over the again wheel’ model – which by the way, in keeping with the check information I’ve seen, as with the ‘Froome Canine’, confers little or no benefit.
An aero huge man
Then there’s the Sean Yates ‘tuck in;’ arms collectively on the tops of the bars, elbows pushed down low and chin nearly touching the stem – this place does confer an aero benefit however isn’t for the faint of coronary heart. I’ve heard, however by no means seen photographic proof that ‘Large Sean’ would take one hand off the bars and tuck this arm behind him to minimize the aero drag much more. Loopy man.
Deep sq. for Merckx and sloping for De Vlaeminck
However the debate bought us to excited about, ‘the common-or-garden handlebar’ over time. Once I began biking again within the early 70’s, the market leaders had been Cinelli with the ‘sq.,’ deep Mannequin 66 ‘Merckx’ or the shallower however nonetheless ‘sq.’ Mod. 64 and the Mod. 65 ‘Criterium’ which ‘flared’ after leaving the central ferrule and was favoured by Roger de Vlaeminck amongst others. In case you had been hip, you knew to cut at the very least 25 mm off the ends of the ‘bars, a subjective factor, they simply appeared higher like that.
Anatomic?
The subsequent vogue was for the ‘anatomic’ bar with ‘straights’ under the brake levers to provide a greater, extra comfy grip. Grooved ‘bars got here alongside to cater for hid cables because the biking actually woke as much as ‘aero.’
Alf along with his brake levers behind the bars
English time trial legend, Alf Engers grasped the significance of aerodynamics earlier than most and positioned his brake levers behind the tops of the ‘bars, tucked out of the wind. The ‘gray males’ of the RTTC – Street Time Trial Council the governing physique in England rushed by way of laws to outlaw ‘King’ Alf’s innovation with a regulation stating that, ‘brakes needed to be operable from the conventional driving place.’
Daniel Gisiger – Lower than aero bars
I used to marvel what these dudes would have manufactured from our subsequent topic – ‘tri bars.’ Eccentric Swiss genius, Toni Maier of Assos fame sowed the seeds within the mid-70’s along with his inverted ‘bars arrange, ridden on the observe by Swiss ‘chronoman’ and tremendous stylist, Daniel Gisiger.
Aero bars for Fignon – However no tri-bars
The East Germans and Cyrille Guimard, supervisor of the mighty Renault professional group shortly cottoned on to the idea and Bernard Hinault and Laurent Fignon had been quickly astride Gitane Deltas. The seek for ‘marginal good points’ will not be a brand new idea. ‘Bull horns’ begat the ‘tri bar’ attributed to Boone Lennon whose background was in downhill snowboarding and properly conscious of the advantages of getting an athlete slip extra simply by way of the air.
The well-known Paris TT
His 1987 patent obtained an enormous stamp of approval from Greg Lemond’s now legendary 1989 Tour de France last time trial triumph. Purists like me might nearly deal with the tri bar however it result in an explosion of ever-more hideous contortions of tubes within the identify of ‘handlebars,’ with Greg Lemond once more on the forefront.
‘a scaffolder’s truck’
Ultimately, issues settled down albeit we needed to endure the ‘Spinacci’ clip on extensions, favoured by the likes of Claudio Chiappucci. It’s not typically I agree with the UCi and their ever-more Draconian guidelines however I needed to agree with them after they out-lawed these items which appeared as if they’d fallen off the again of a scaffolder’s truck.
Matej Mohoric ‘pet paws’
This in fact result in riders adopting what Eurosport commentator, Carlton Kirby now nauseatingly refers to because the ‘pet paws’ place, forearms on the tops, and earlier than Shimano hid all of the management wires, gripping the cable outers. The professionals are all expert bike handlers however not a secure factor to witness from kids on a membership run, in search of to emulate their idols.
Don’t do this at residence
The search to get aero meant that the outdated idea of broad bars, 42, 44 and even 46 cm. broad ‘to maintain your chest open and help respiration’ has flown straight out the window with riders like Adam Hansen adopting ever-narrower ‘bars within the quest to cut back their aerodynamic signature. I learn an article the opposite day discussing the advantages of 34 and even 30 cm. broad ‘bars – I received’t be shopping for these any time quickly – however extra on slender ‘bars later.
Victor Campenaerts – Aero, however…
Nonetheless, I did like Ritchey’s over-size ‘bars; the bigger diameter ideally suited you probably have huge arms, comfy and robust – however Ryanair nonetheless managed to bend mine. After preliminary issues about energy, ‘King carbon’ pushed alloy apart because the primary materials for ‘bars – nevertheless, you may nonetheless race on with bent bars after a crash, troublesome to do with half a handlebar dangling by the cables.
Two is healthier than one
The connection of handlebars to the saddle is a side on which there’s no exhausting and quick rule, regardless of the coaching manuals and bike fitters doctrines. Pippo Pozzato took ‘slamming’ to new ranges with an enormous drop from saddle to ‘bars, a place which some observe sprinters would discover too excessive for a ten second effort, by no means thoughts the seven hours of the Primavera. However then Giovanni Battaglin pulled off a Vuelta – Giro ‘double’ in 1981 along with his ‘bars stage with the saddle.
Battaglin had no drawback with aerodynamics
In latest occasions the demand for ever-more ‘aero’ has result in ‘airfoil’ tops to ‘bars and ‘cockpits’ with one piece carbon ‘bars and stems – clean and glossy however expensive and unforgiving if you wish to tweak your place.
Not a lot adjustment there
Then there’s the cross-over from gravel; shallower and flared as favoured by the likes of former World Factors Race Champion, Jan-Willem Van Schip. He’s an enormous man at 6’4” however driving ‘bars simply 32 cm. broad in his quest to, ‘get aero’.
Aero, possibly… A great look?
The long run?
We return to that man Van Schip, who, together with Dutch firm Speeco has developed the ‘Speeco ABB [Aero breakaway handlebars]’ with built-in stem. Value? A mere 1,500 Euros with 500 of that as a deposit.
€1,500 price of handlebar
