Thank you for the video! Regarding the portable aerodynamic device: better spend your money on a real wind tunnel test instead of something like that...
@@cyclistshub I found an American company which offers wind tunnel tests for around 600$ per hour. While this is certainly expensive a wind tunnel test is only necessary if you optimised anything else and you're very competitive (and successful with it). But then I really don't see how the body rocket will be accurate enough. I mean, we're talking about small body changes with little differences...
@@Xarx42 Yeah, as you said, 99.9 % of us won't use it. 😅 Good point about the accuracy; I forgot to ask. But given the scale and the granularity of the charts, I believe it will be pretty accurate.
@@cyclistshub Ah well, you can take any kind of data, polish over it just hard enough and make some graphs out of it... :D My fluid mechanics lessons are quite some years in the past now, but what I do remember: turbulent air (or any fluid) is an absolute pain in the a**se to calculate with. Thats one of the reasons wind tunnel systems are so big: to absolutely assure all the air coming to the test object is laminar and you can actually measure anything meaningful. I promise you with such a small setup everything will be turbulent. Is it complete BS? Who knows, but I am relatively confident it has not the accuracy thats needed for the athletes who would need such a device.
I understand. Well, I don't know all the technical details and principles, but from what I understand, they measure the change in force at all contact points. So if the ride position improves (CdA decreases), the force on those sensors will also decrease. 🤷♂️

Well, there are many pros and cons of using a smartphone instead of a bike computer. I have a fully dedicated article on my website: www.cyclistshub.com/bike-computer-vs-smartphone/.
Hope you are feeling a lot better now. Interesting content as usual. Thanks.
Hi Paul, yes, I am finally feeling better now. 😊🙏
Good to see you back and an interesting selection of products.
Thank you!
Hope you are feeling better! Thanks for the upload!
Yes, I do. Thanks!
Mate that body rocket stuff seem to be nice helper for finding ideal TT position ;)
Yeah, but I am sure it will have some limitations like the TT bike it's compatible with, etc.
Awesome feature! Thanks 😎👍
Thank you!
Thanks for uploading
Hope you're feeling better 👍
Hi Neil, yes, I am. Thank you!
@@cyclistshub great video!
Thanks a lot! I shot it when I had shivers. 😀
@@cyclistshub you did a great job. I know how hard Eurobike can be; I was always drained for days after.
Exactly. For an introvert like me, it's very draining.

I am glad you like it. :-)
Hard to say, I found Body Rocket interesting. How much does it cost to have a session in the wind tunel?

Dimples on bike parts is marketing gimmick. Dimples on golf balls is to control and enhance flight. A bike does not fly in the air.
Hi Dan, yeah, I thought so. Thanks for your explanation. 😊
