Do aero wheels really make a difference?
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%.
How many watts do you save with 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.
Are aero wheels heavier?
The most aerodynamic wheel in a straight line, flat course with no side wind, is a disc. All the aero benefits come with a penalty though; aero wheels are heavier than a standard spoked wheel thanks to the extra materials used in the rim fairing meaning more energy is needed to get them up to speed.
What makes a wheel Aero?
An aero wheel however, has a much deeper rim profile and an increased surface area. The increased surface area generates a higher drag force. An efficient fairing shape will increase the side force. The key is to design a fairing shape that produces a higher percentage of side force relative to drag.
Why are aero wheels faster?
These aero wheels are fast in two ways. First, their smooth airfoil shapes pass through the air a lot more cleanly than a box-section rim. The tyre is the leading edge and splits the air. Behind it, a deep rim controls the airflow, helping it to come together again smoothly.
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.
Are aero bikes really faster?
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 faster are 50mm wheels?
2-3mph
50mm is going to be a bit faster for a novice rider, wanting to get up a group in chaingangs etc. Average speeds can increase 2-3mph over box-section wheels. Good for bunch riding and fast stage racing for all levels. 60mm is the way to go for smooth rolling roads where outright speed is paramount.
Will an aero bike make me faster?
What do aero wheels do?
Because aero wheels are flush with the tire, they provide a flat and smooth surface that keeps the airflow out of the wheels. With conventional wheels, some of the air flows into the wheel barrel, creating drag. Aero wheels block out the air and instead force it to flow past the wheels.
What depth wheels do pros ride?
Despite the name, the rims on these are actually 37mm deep. They’re a little lighter at 637g (front) and 747g (rear).
Is 20 mph on a bike fast?
More experienced, short-medium distance (say 20-30 miles): average 15-16 mph. Reasonable experience, medium (say 40 miles): average around 16-19 mph. Quite competent club rider, some regular training likely, medium-long distances (say 50-60 miles): 20-24 mph.
Are aero bikes uncomfortable?
If you’re not flexible then yeah, an aero bike can be uncomfortable at first. Depends on how you do it. A properly fitted aero bike will likely be more comfortable than a poorly fitted endurance bike. Also, keep in mind that, from an aerodynamic standpoint, the bike is not most people’s problem.
At what speed does an aero bike make a difference?
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.
Is 50mm wheels good for climbing?
They are light and climb very well too. Best all-rounder. 50mm is going to be a bit faster for a novice rider, wanting to get up a group in chaingangs etc. Average speeds can increase 2-3mph over box-section wheels.
Are stiffer wheels faster?
What you will get from stiffness is accuracy when cornering. Bigger tyres on a wider rim will make you faster down and around, but not up. lighter/stiffer wheels will only really help you on the climbs as you’ll get better power transfer on a stiffer wheel and faster acceleration on a lighter one.
At what speed is an aero bike faster?
What is the fastest 1 mile time on a bike?
In 2011, Markus Stockl flew down Nicaragua’s Cerro Negro volcano at a staggering 102.4 mph — that’s a 35-second mile, or about four times the speed of an average professional road cyclist.
How fast should I cycle for my age?
The Average Cycling Speed By Age: The Brief
18–25 years: 17–18.5 mph. 25–35 years: 20.8–21.7 mph. 35–40 years: 18.6 mph. 45–50 years: 15 mph.
Can you use an aero bike for long rides?
I’ve done 150-250km rides on an aero bike, race bike, and a gravel bike (endurance geo), and was perfectly comfortable on all of them. Theoretically, you should be able to go faster on the aero bike, thereby spending less time on the bike, which should result in less discomfort, or at least for a shorter duration.
Do aero bikes climb well?
Aero bikes can still climb. Weight is a big deal for riders interested in climbing, and aero bikes generally weigh more than their non-aero counterparts because more material is needed to create aero-shaped frames. But the difference may not be as big as you think.
Are aero bikes less comfortable?
You cause more drag than the bike and tyre rolling resistance will slow down narrow high pressure tyres on averagely poor road surfaces. Assuming the aero bike fits (reach, saddle to bar drop etc,.) the same as the non aero bike it would be just as comfortable.
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 deeper rims faster?
At gradients of less than 5%, deeper wheels are definitely faster. And at gradients of greater than 5% — at least at our amateur speeds — lighter wheels will be faster. For this average of 5% and an average speed of 10.5mph, the deeper wheels were slightly faster.
What depth rims do pros use?
40-60mm
“For most people the ideal would be a mid-section rim of 40-60mm; that’a a jack of all trades.
Are lightweight meilenstein wheels worth it?

The Lightweight Meilenstein Obermayer wheels are incredibly light, incredibly stiff and incredibly expensive.
Are lightweight wheels worth it cycling?
“Light weight wheels accelerate faster than heavy ones, which helps when you’re taking off from a stop, but heavy wheels maintain more of their momentum than light wheels, which helps you keep your speed on rolling roads and trails.
Is Aero more important than weight?
For hobby riders, the average gradient where weight is more important than aero is 4.5% or more [see above]. For pro riders who have a higher speed, it is around 7.5%. Once you are doing more than 15km/h (9.3mph), the aerodynamic drag is the biggest resistance for the rider.
How many miles do aero wheels add?
It averaged an increase of 3.4% in consumption efficiency and added about 10 miles of range. Range with aero covers driving at 50 miles per hour increased from 312 to 322 miles.
How many watts do aero wheels save?
Are lightweight wheels worth it?
Lighter wheels are better for fuel consumption. Heavy wheels add to the total weight of the vehicle. However, the weight of your wheels will not play a big role in acceleration, top speed, and the vehicle’s general performance on the road. It’s typically not worth paying more for lightweight wheels.
What is a good weight for a wheelset?
Conclusion. Road and Triathlon Bike Wheels Weigh 1400-2000 grams in average cases, and it varies between 1000 to 2500 in an extreme case.
Do lightweight wheels make a difference?
Lighter wheels can go faster because there is less weight to control. They’ll help you speed up your acceleration while decreasing the time it takes you to come to a full stop. They can also contribute to greater fuel efficiency because lighter vehicles use less fuel.
At what speed does Aero matter?
“At speeds near 30 mph, 90 percent of your power goes into overcoming air resistance.” At 10 mph, half of your power is going to overcome air resistance, Barry says. “The slower you go, the more time aerodynamics will help you save, because you’re spending more total time on the road.
Can you climb with an aero bike?
Aero bikes can still climb. Weight is a big deal for riders interested in climbing, and aero bikes generally weigh more than their non-aero counterparts because more material is needed to create aero-shaped frames.
How much range do you lose without Aero wheels?
The analysis of the test data showed that the Aero Wheel caps reduce fuel consumption by three percent at 150 kph motorway speed. Calculated on a fully charged battery, this means a range gain of eight kilometers compared to driving without the caps.
How much difference do the aero wheel covers make?
On average, the aero covers reduced consumption by 4.5%, equating to a boost in the range from 305km (190mi) to 320km (199mi). When averaged over the three speed tests, the aero wheel covers were 3.4% more efficient.
Best all-rounder. 50mm is going to be a bit faster for a novice rider, wanting to get up a group in chaingangs etc. Average speeds can increase 2-3mph over box-section wheels. Good for bunch riding and fast stage racing for all levels.
At what speed do aerodynamics matter?
Aerodynamics start to have a more noticeable affect on a vehicle at around 50 mph. If you’re traveling slower than 50 mph, the weight of the aerodynamic devices are probably more of a penalty than any perceived gain in performance.
Do lightweight wheels really make a difference?
Do lightweight wheels save gas?
How much difference does wheel weight make?
Reducing the wheel weight in a performance vehicle – especially one meant to take corners, means you’ll quickly find better handling when you’re behind the wheel. In tests, drivers saw substantial improvements in lap times when they cut 12 pounds off each wheel.
Why are lightweight wheels good?
Are aero bikes good for climbing?
Are aero bikes actually faster?
The entire point of riding bicycles is to increase the speed at which humans can travel for the same effort. Aero bikes really lean into this because when it comes to going fast, aerodynamics are what count.
How do wheel covers reduce drag?
On the wheel covers, they produce “a flutter effect that reduces drag,” he said. The covers are made of ABS plastic, which is known for durability and flexibility, Kronemeyer said. They fit within the bead curl on steel wheels, and that helps hold them in place.
What car shape is most aerodynamic?
teardrop
The most aerodynamically-efficient shape for a vehicle is, in theory, a teardrop. A smooth shape minimises drag and the profile, if correctly configured, keeps airflow attached to the surface rather than breaking free and causing turbulence.
Do lightweight wheels improve MPG?
Our lightweight wheels will also save you money at the pump by improving your fuel economy. According to testing by TireRack.com, a combined 3 lb reduction per corner (wheel and tire) improved freeway MPG by 5%.
