- An in depth explanation of how "Aero" wheels are more aerodynamic than shallow box section wheels.
This covers all basic principles of aerodynamics (Terminology, Density, CDA, Reynolds Number, Humidity).

Mavics don't seem to do well in independent wind tunnel tests and reviews I notice, even though it has as you say the preferable NACA profile. Why do you think that might be?
A rare video of Hambini without any swearing!
I live in the US and I’m a member of a Cycling Club with 600 plus members, I’m glad I found this channel and can share all this knowledge with my Cycling buddies.
Considering the complexity of the subject, you presented it very well. There is a teacher in you!
I had no idea about aero in wheels (or anything else) until I watched this video. Very informative and clear. Thanks so much.
I have bike raced since the early 80's. One of my friends who bike raced had a dad who in my opinion is the founder of modern fluid dynamics, and has authored a number of college texts on fluid dynamics. I remember one day years ago running into him and we talked about aero bicycle wheels, namely Zipps. They had just come out with the dimpling. When I asked him what he thought, he replied, "Figuring out drag coefficients is a black art, even with the best computer programs. I don't know where Zipp gets their numbers from but they are really creative." Thank you for this.
Thank you for taking the time to make a clear explanation of a complex topic.
holy nuts as a high school physic student, this stuff consolidates my learning!
This was outstanding! And it help me decide on a getting an upgrade. Thank you so much!
I love this portal AC. We can move around the house. Definitely need it for the hot summer.
Found you through TheDarkInstall's 'dark' live sessions.
Awesome video. Just discovered your channel a few weeks ago and its content is gold.
Wow!!! I am impressed. Video was very professional without any usage of foul language. Thanks Hambini
Great! Impressive review far more thorough than any other I have come across.
Have been a fan since day one. This is to date, in my opinion your best video. Thank you for the masterclass Hambini I learned a lot from this video.
Great work, well done. I'm both, bike mech and a pilot, and really enjoyed the video. Thanks.
This was an incredibly well done presentation Mr. Hambini. I think my students will very much enjoy watching this. So, I am going to show this to them tomorrow. (I am a physics instructor.) Thank you and kind regards.
I have watched this video 6 or 7 time now it's just so interesting.
Hey amazing video and I really enjoyed it! Just a disclaimer, I have no degree in engineering but as I understand some of the research out there is that the reason the wheel industry moved away from the NACA profile and into toroidal shapes is due to stability considerations. Apparently, the average yaw angles that cyclists encounter are between 5-10 degrees and this is where the toroidal shape performs better than NACA profiles (and some claim to have a "sailing" effect" akin to sailing into the wind). Also, I read somewhere that the discontinuity between the tire and the rim actually creates a beneficial vortex that causes airflow to reattach to the rim (if the tire is narrower than the wheel). And one last thing about toroidal shapes is that it creates a similar profile between the leading edge and the trailing edge of the wheel-tire system. For sure some of these is marketing as some of the research where than by the wheel manufacturers but I would like to hear your thoughts on this.
You have truly enlightened my inner geek, I thank you young Sir.
