What's the best track helmet for events like the flying 200m or the Kilo?

The Giro ones that the British Olympic squad have look pretty good, don't know if they're widely available yet though.

Apparently something a little more old school doesn't stop you from winning gold and breaking world records either. I don't know what brand/model though.

62vette, my helmet has ventilation holes in it and the helmet in the 2nd pic is still way better than mine.

I say you'd have to be down in the low 1minutes for the kilo to start worrying about aero dynamic helmets.And even more so in a 200m TT.

Who said anything about being worried? But I want me something with the sleek lines like in the first pic, sometimes I feel like 15% of my total drag is comin off my head and helmet what with the whistling I hear in my ears as the air blows over and around my helmet and when it actually buffets it side to side and forward and backward.. Having one of those should be good for a 15-20 k TT too. In terms of cost effectiveness, I think a good aero helmet is a better option than buying a new, expensive, low drag bicycle with deep aero rim wheels.

The Louis Garneau ones are pretty cool loking anf it like a glove. I've just got one and am most impressed,though admittedly the Giro ones BC use look better and appear more aero. The Aussie helmets are well long and sleek too! Anyone know where us mere mortals can buy these?

Ofcourse an aero helmet will work in a 15 to 20km TT.But buying a helmet over some lighter faster wheels,go right ahead lol.

Laugh all you want Lasalles, but according to this site:http://damonrinard.com/aero/aerodynamics.htm, an aerodynamic helmet saves 5.2% drag over a person who wears no helmet, and is 2nd on the list of changes that most effects aero drag with running a disc front wheel at 7.2%. The disc wheel costs a lot more than the aero helmet, but I don't know where I can get a good aero helmet. I know that the helmet I wear has worse drag than when I don't wear a helmet, because I feel slower than when I went out helmetless, but after my crash I will never go out riding without a helmet again.

Ok now lets work this out.Firstly you wouldnt be allowed to attempt a flying 200mTT without a helmet so the 5.2% doesnt matter.So say an aero helmet in comparison to a helmet (say a Limar),now it may be say 3% more aero.So now if you were riding 12seconds for a 200m and add the aero helmet your time would drop by 0.03seconds.Any Actuaries or Mathamaticians here as my maths isnt real good? By dropping 0.03 seconds suddenly doesnt sound worthwhile of an aero helmet.

Going by the 12 seconds and 3 percent thing you would actually be saving .36 of a second and your time would be 11.64. Not bad for a relatively small investment compared to a disc wheel. |

even if it is only 0.03 of a second its better than nothing. at nationals i missed out on qualifying in the sprint by 0.02...so if i had that helmet i would of qualified. it all depends on how close the competition is. think that came out right

The no helmet situation is with a shaved head. Gentlemen, you are misordering. Wearing a crappy non aero helmet > no helmet, hair > no helmet, shaved head > aerodynamic helmet. This means that a aero helmet could carry 10% aero advantage over a standard helmet.
