Specialized compared the performance of its Prevail standard road helmet, Evade aero road helmet (below) and S-Works TT helmet in the Win Tunnel and concluded that switching from the Prevail to the Evade would save you 40 seconds over 40km (25 miles).

Do aero helmets make you faster?
Clearly an aero helmet does make you faster by a measurable amount, but it’s not quite free speed because the reduced ventilation means you pay in heat build-up. Unless you live in a cold climate, we would probably not recommend an aero helmet for use as your sole, everyday lid.
How much faster is a time trial 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 is an aero bike?
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 much difference does a skinsuit make?
It is estimated a close fitting skinsuit can save 3.2% of your total energy. [1] This equates to 29 seconds in a 40 km time Trial. Therefore a close fitting skinsuit represent a cost effective way to improve aerodynamics and save valuable seconds.
How many watts do aero helmets save?
Feel the Need for Cycling Speed? This Chart Will Help You Ride Faster
| UPGRADE | COMPARED TO | ESTIMATED POWER SAVINGS1 |
|---|---|---|
| Time Trial Helmet | Standard road helmet | 11.5 watts |
| Shaved Legs | Unshaved legs | 10 watts |
| 3-Spoke Wheel (back wheel, 0 yaw) | Disk wheel (back wheel, 0 yaw) | 5 watts |
| Road Aero Helmet | Standard road helmet | 3.5 watts |
How much does an aero helmet help in an Ironman?
Aero helmets typically save 30-60 seconds for every hour of riding. The actual time saved for a triathlete depends on how well the helmet smooths the airflow from the helmet to the middle of the back.
How much of a difference does an aero bike make?
Basically, it makes no difference. Even on a 10 per cent hill, travelling at a pretty brisk 15kph (a feat that requires our 70kg cyclist to put out around 350 watts), that 2kg will only save you around 9 watts. You can use a power vs speed calculator to try the maths out for yourself.
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%.
Which aero bike is the fastest?
Canyon says that the 2021 Aeroad is the fastest race bike available, saving you 5.4 watts at 45kph compared to the outgoing version. At 7.3kg it’s not heavy either, despite wide, deep tube profiles.
How much faster are Skinsuits?
When compared to a jersey and bib shorts, our testing has shown that a skinsuit is 21 to 28 seconds faster on a 25-mile-time trial when travelling at around 25mph. We tested this at a velodrome, using aCdA (coefficient of drag * area) measuring system.
Does a carbon bike make you faster?
However, a small experiment conducted recently by Cycling Weekly demonstrated that a cyclist generating 200w of pedalling power on an aero carbon bike was 1.7kph faster than on a lightweight carbon bike – extrapolated over four hours riding they claimed this would translate into an extra 6.6km distance travelled.
At what speed does aerodynamics matter on a bike?
At what speeds do aerodynamics make a difference on a bicycle? At speeds over 10 mph (16 kph), aerodynamic (aero) drag becomes the dominant force of resistance, with no wind on flat terrain: At 18 mph (29 kph) it becomes 80% of the resistance. 25 mph (40 kph) it becomes 90% of the dominant force.
How many watts does a waxed chain Save?
3-5 watts
A WattShop waxed chain saves 1-1.5% of your total power output, typically 3-5 watts for most riders. Each chain undergoes a 3 stage ultrasonic cleaning process before being ultrasonically bathed in a paraffin wax and a unique blend, after which it is dusted with PTFE powder to reduce drivetrain friction yet further.
How much time does aero bars save?
This means that the true saving of aerobars compared to a similar aero position on a bike without them is about 1:15mins.
Do you need an aero helmet for Ironman?
The short answer is no.
Is no helmet more aero?
At par value, an aero helmet will be faster in 99.9% of cases, except in a rare freak case where someones head is an aero genetic anomaly. If you wear an aero helmet, you will have less drag than if you’re not wearing any helmet. That’s because even if you have short hair, it creates drag.
Do helmets matter in Zwift?
We found that what you wear on your virtual head makes virtually no difference. All helmet choices (including no helmet) were within 1-2 seconds of the same time over the 29.8km (18.4 miles) Watopia Figure 8 route.
Why do cyclists wear aerodynamic helmets?
Aerodynamic shapes reduce this pressure drag by minimizing that difference in pressure and allowing the air to flow more smoothly over your front and reduce the low-pressure wake behind you.
What helmet do triathletes wear?
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.
What helmet does Jan frodeno?
Oakley aero helmet
Did you spot Jan Frodeno’s Oakley aero helmet at the IRONMAN World Championships last week? We’re very excited that Oakley’s hotly anticipated helmet range will be coming to Wiggle from early next year.
