What is the difference between Aero and time trial helmets?
- Aero (Time Trial) Helmets vs Road Cycling Helmets. Time trial helmets are often used in triathlon to decrease wind resistance while riding in the aero position. Also called an aero helmet, these racing helmets offer a sleek design that allows the rider to be more aerodynamic, in turn potentially improving performance.

How can I make my helmet more aero?
While racing on the track over the years I always wore an aero helmet with a visor. The same was true for all of my biggest individual time trials while competing around the globe.
Do you need an aero helmet for Ironman?
The short answer is no.
How much of a difference does an aero helmet make?
How much time and power do aero road helmets save? A properly-fitting time trial helmet compared to a standard road helmet is worth about a minute over 40km, according to Michael Hutchinson, multiple national time trial champion and author of Faster: The Obsession, Science and Luck Behind the World’s Fastest Cyclists.
How much faster will aero wheels make me?
Using aero wheels has been found to reduce a cyclist’s CdA by 3-5%, so if you generate 350W of power, using aero wheels could see your speed on the flat rise from 44.6kmh to 45.4kmh, an increase of 1.63%.
Why are aero bikes heavier?
Endurance and lightweight bikes will often have long seat tubes to allow for some flex and provide additional comfort. The extra material required for aerodynamic tubes adds to the weight of the bike, as a consequence aero bikes are heavier than lightweight bikes even if they share the same geometry and specifications.
Are aero helmets hot?
As a rule, aero road helmets are a little warmer than standard helmets. If you suffer with a hot head when riding or if it’s a very hot day you might want to steer clear, but you’ll probably find a lot of the aero road helmets out there these days are comfortable in most conditions.
Is no helmet more aero?
Bare head had similar air resistance to aero helmets at low yaw angles and the lowest resistance at large angles. The paper’s conclusion is that for helmets (or bare head) that do not have huge number of vents, cross sectional area has more effect than the shape of the head or helmet.
Which aero upgrades get you the most for your money?
Aero Upgrade: Aero Helmet An aero helmet is one of the really good value upgrades you can make, getting you the most bang for your buck. A well-fitting time trial helmet can save a rider traveling at 15mph up to three minutes over 56 miles, at 20mph two-and-a-half minutes, and at 25mph around 1:50 in time.
How much time will aero wheels save?
The time savings for good aero wheels are significant, according to Barry’s research on the SystemSix and its new Knot64 aero wheels. Even on an aero road bike, the addition of aero wheels saved 48 seconds over a 40K TT at 300 watts compared to a typical 30mm-depth alloy training wheel set.
How much faster is a TT helmet?
Results. As you may have expected the time trial helmet is significantly faster. If travelling at 25mph for 60 minutes there is a saving of 8.5 watts, which in real terms would equate to a substantial saving of 49 seconds.
How much faster are aero bikes?
With an aero bike, you’ll simply be able to go faster than you would with a non-aero bike. The 150-Watt rider riding during a windy day now finishes 6.5 minutes faster on an aero bike (8.4 minutes with no drafting) and is 83.3 seconds per hour faster (93.6 seconds with no drafting).
How can I make my road bike more aero?
Free speed: Six ways to make yourself and your bike more aero without spending money
- Lower the front end.
- Improve your flexibility and core strength.
- Change your bottle cage position.
- Change your hand position.
- Zip up your jacket.
- Zip tie your cables.
- Cling film your helmet.
At what speed do aero wheels work?
Aero Wheels “Smooth” the Air Flow They create less drag turbulence. Ideal aero wheels get better at this as they spin faster. Most manufacturers will tell you that the aero properties do not really come into play until a certain speed threshold has been passed — typically at the very least 20 mph (32 kph).
