Aerometers and Marginal Gains
Aerometers have made it to market and promise some real time measurement of marginal gains. Take a listen as our special guest Michael Liberzon, host of the Endurance Innovation Podcast talk about their journey to bring this game changing technology to market.

Not sure why nobody is mentioning the PowerPod by Velocomp. They have been in the business ins 2008 and have 15 years of tech advancements and upgrades.
Sent a text but not sure it went through.
I have looked everywhere and have not found where you have reviewed or looked at the cda/power meter “PowerPod” by www.velocomp.com.
They have been around since 2008, they have now 15 years in improvements in electronics, algorithms and is pretty user friendly. John Hayman the owner has the patents that the others infringe upon. He would be a great guest on your podcast.

If real time CdA is difficult to measure because the test is dominated by other factors (low signal to noise ratio), doesn’t it mean that CdA-related gains are even more marginal than other marginal gains?
Hey
First of all, thank you so much for the podcast. Every time, I learn more and more about all the small details, which compined can make such a difference. And, with all my new gained knowledge, I’m not only helping myself, but also my 62year old dad, who despite his competitive nature, just doesn’t get why tires and chains are so important. But, he is getting there, and he is feeling the difference.
My questions is regarding the effectiveness of well placed tape, with the purpose of smoothing out surfaces, covering gaps, and the like.
My main focus is long distance triathlon, so I am looking for all the small savings I can get. Right now, I ride af Felt IA Disc, which for example, has a gap between the front brakecable-cover and the fork. This gap, creates a little crevasse, which I have now covered with som electrical tape. My guess being that air would otherwise get caught in the crevasse, and the result being turbulence and drag.
I have also taped over the stembolt-holes, again, to avoid having four small holes pointed into the wind.
I’ve identified several more places, where well placed tape could help smooth things out.
So the question is, is this worth doing or am I just wasting my time? And are there more to consider, for example, to shape the tape more pointy, instead of just covering a gap? Maybe using something like Tesa 4613 tape, since the slight ribbled surface could work like the dimbles on a golf ball?
Again, thank you so much, and have a great day!

Georg: We’ve measured increases in rolling resistance with decreasing ambient temperature in field tests. I think Tom Anhalt estimates that Crr changes a bit more than 1% with each deg. C.
