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 brought about fairly a stir on Monday when the rider’s of the Dutch crew used it in Tirreno-Adriatico’s stage 1 time trial. This offers us the chance to look again at Ed Hood’s tackle the aerodynamic query just a few 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 good friend Ed Hood suffered a critical stroke in February. We don’t anticipate Ed will make it again into our bunch, so we’ve began a GoFundMe web page to assist Ed together with his future. Learn the total put up right here – and please think about donating.

We’ll be posting a choice of Ed’s work from the previous 16 years, as a result of nice story-telling by no means will get previous.
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 have a look at descending, handlebars and aerodynamics typically.
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 an excellent look
So, the place which ‘The Froome Canine,’ employed to show that he might truly look worse on a motorbike than he often did has been banned. In his case, no loss, I might hardly bear to observe him, he regarded so ungainly – however I’ve to confess that watching the likes of Matej Mohorič undertake it was fairly spectacular.
Mohorič – Spectacular
Wind tunnel exams would point out that other than being damned uncomfortable and tough to take care of, the aero benefit is negligible. Some are in favour of the place, arguing that it’s spectacular to observe, provides curiosity to the game and nobody has crashed while using it. Critics would add the phrase, ‘but’ to the tip of that sentence and endorse the UCi stance.
Pantani – off the again
However ‘rad’. Descending positions are nothing new, keep in mind the late Marco Pantani’s, ‘bum over the again wheel’ model – which by the way, in line with the check information I’ve seen, as with the ‘Froome Canine’, confers little or no benefit.
An aero massive man
Then there’s the Sean Yates ‘tuck in;’ fingers collectively on the tops of the bars, elbows pushed down low and chin virtually 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 ‘Massive Sean’ would take one hand off the bars and tuck this arm behind him to reduce the aero drag much more. Loopy man.
Deep sq. for Merckx and sloping for De Vlaeminck
However the debate received us to interested by, ‘the standard 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 not less than 25 mm off the ends of the ‘bars, a subjective factor, they simply regarded higher like that.
Anatomic?
The following trend was for the ‘anatomic’ bar with ‘straights’ under the brake levers to provide a greater, extra snug grip. Grooved ‘bars got here alongside to cater for hid cables because the biking actually woke as much as ‘aero.’
Alf together 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 – Highway 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 fabricated from our subsequent topic – ‘tri bars.’ Eccentric Swiss genius, Toni Maier of Assos fame sowed the seeds within the mid-70’s together with his inverted ‘bars arrange, ridden on the monitor 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 crew shortly cottoned on to the idea and Bernard Hinault and Laurent Fignon had been quickly astride Gitane Deltas. The seek for ‘marginal beneficial properties’ isn’t a brand new idea. ‘Bull horns’ begat the ‘tri bar’ attributed to Boone Lennon whose background was in downhill snowboarding and nicely conscious of the advantages of getting an athlete slip extra simply by way of the air.
The well-known Paris TT
His 1987 patent acquired an enormous stamp of approval from Greg Lemond’s now legendary 1989 Tour de France remaining time trial triumph. Purists like me might nearly address the tri bar but it surely result in an explosion of ever-more hideous contortions of tubes within the title of ‘handlebars,’ with Greg Lemond once more on the forefront.
‘a scaffolder’s truck’
Finally, 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 once they out-lawed these items which regarded as if that they had fallen off the again of a scaffolder’s truck.
Matej Mohoric ‘pet paws’
This after all 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 protected factor to witness from kids on a membership run, searching for to emulate their idols.
Don’t do that at residence
The search to get aero meant that the previous idea of extensive bars, 42, 44 and even 46 cm. extensive ‘to maintain your chest open and assist 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. extensive ‘bars – I gained’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 perfect in case you have massive fingers, snug and powerful – however Ryanair nonetheless managed to bend mine. After preliminary considerations about power, ‘King carbon’ pushed alloy apart because the primary materials for ‘bars – nevertheless, you possibly can nonetheless race on with bent bars after a crash, tough 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 laborious and quick rule, regardless of the coaching manuals and bike fitters doctrines. Pippo Pozzato took ‘slamming’ to new ranges with a large drop from saddle to ‘bars, a place which some monitor 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 together with his ‘bars stage with the saddle.
Battaglin had no drawback with aerodynamics
In current instances the demand for ever-more ‘aero’ has result in ‘airfoil’ tops to ‘bars and ‘cockpits’ with one piece carbon ‘bars and stems – easy and smooth 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 a giant man at 6’4” however driving ‘bars simply 32 cm. extensive in his quest to, ‘get aero’.
Aero, perhaps… A superb look?
The longer term?
We return to that man Van Schip, who, along with Dutch firm Speeco has developed the ‘Speeco ABB [Aero breakaway handlebars]’ with built-in stem. Price? A mere 1,500 Euros with 500 of that as a deposit.
€1,500 price of handlebar
