- In the third episode of the Aero Round Table our Swiss Side engineers talk about the importance of aero wheels, how to find the right setup, the myth of the 105% Rule, tubeless vs. tube and so much more.
15 Minutes of pure cycling value, served hot for all the swisssiders out there. Sit back and enjoy the ride.

Do you also consider vibration related losses? Real roads are not smooth. How much watts are being wasted when using thinner tires compared to wider like 30's?
The addition of chapters to the timeline would really help with returning to sections to return to specific topics.
According to many rolling resistance sources, Latex tubes have the lowest rolling resistance of any system. Certainly faster than TPU (marginally), so I'm interested to know where you're basing you info saying latex is 3rd on your list
Tubeless is the lowest now
Also latex tubes have some safety issues when used in clincher wheels. If you install them correctly, there is no problem, but it is very, very hard to install them correctly. They have an amazing knack for getting pinched between the bead and the rim, where they will often work for some amount of time then explode releasing all pressure immediately. I've seen pro race team mechanics screw this up, bike shop mechanics screw it up, experienced racers screw it up. You really have to be meticulous and check every centimeter of each side of the rim before inflating fully.
@@JackMott I have been using latex tubes for 20 years and continue to use them on most of my bikes. I've never had an issue installing them
@@yogatriathlete I knew someone would reply like this. It is a natural law of the internet. "Not a problem for me". That is great, it is for some people. You may naturally be meticulous and so do not have problems. Meanwhile other people have broken their faces because they did have problems so it is worth warning people. I used them for 10 years myself, and once I learned you need to be meticulous I also did not have problems. Now I use tubeless because it is even faster and less hassle.
@@JackMott The only reason tubeless tires are faster (as a system) is because all the research and development is now going into TLR technology, while tube-type clinchers are slowly becoming outdated. But if you look at just the air retention system by itself, latex tubes are still one of the fastest (lowest rolling resistance) methods available. I know there are many other advantages to using tubeless, or TPU tubes, or even Butyl tubes, but when you only look at rolling resistance, you cannot get faster than a latex tube. There is supporting data and not just me saying so
I would add a note that many many people are able to ride in very aerodynamic positions without ever doing core work and strength training. Often a small adjustment in position can provide enormous relief where no amount of weight training would. So please do not assume if that core work is the answer
if you have trouble getting aero, maybe it will be, maybe it will not.
Brilliant podcast, glad you tube showed me this. Keep up the good job guys!
Why is bike geometry never considered when considering handling and stability? Deep wheels need different steering geometry than shallow, but it never seems to come up in these discussions. Just curious if it is discussed behind closed doors
Aerodynamicis, Aero, Aero, Aero..... Aero..! Bla bla bla bla bla... And not a single word about "rotation balance". I promise, by 2026 Aero will not be mentioned unless it is together with rotational balance. WHY?! It's called Newton's first Law.... A mass that is put in motion will continue in motion unless it is interrupted by an outside force (i.e. aerodynamics), or an oscillation (I.e. balance). An F-1 car is built around Newton's First law, Aerodynamics & Balance... So should Aero Carbon Wheels.
Mark my words.
Are there any situations where the "sailing effect" works against you? Since you compare it to sailing, if you position the sails the wrong way, you would slow yourself down rather than having them push you forward. On a bike you don't have the option to position you wheels in the most favorable position
if you look at yaw sweeps of aero wheels they are never slower than non aero wheels, but what shape you pick may have downsides at some yaw angles vs others. One wheel may be better at low yaw vs high yaw. A faster cyclist doing short TTs may prefer a low yaw optimized setup than a slower cyclist doing longer events (slower speeds )
