I came across Tri Rig’s new service of online virtual bike fitting and/but also helmet and bottle positioning aero advice?
How would that be possible in an online setting without confirmation of the data, on the aero part of course? You can do an online bike fit, i’m not really into that but how would you validate if helmet X or helmet Y is faster without real testing or bottle set up X or Y?
No, for you 2 bottles behind each other is faster then 1 bottle higher up and second lower, or 3 bottles faster then 2 with helmet X but not with helmet Y?
Did anyone did this? Just curious as I like their products but how would you get this done?
Send you different helmets to try and after that send them back?
I just don’t see how you can give an aero advice without real testing and validating what you think is fast is really fast(er).
Even if you have a boat load of aero testing experience it seems that it would be still aero-guessing if you can’t actually test.
Maybe @realbdeal can shed light on this, i’m interested how you would pull this off.

It’s just going to be percentages. “This placement works best for 80% of people”, “In 70% of testing two bottles tested faster than one”.
It’s more like giving someone a baseline of whats probably going to work, but with a pretty big margin of error.
I think the only way to pull this off virtually with validated results would be to use a tool like AiRO.app. I wonder if the tririg folks have looked into using this and embedding it into their service (perhaps for a different fee?).
Outside of personalized cfd testing (ie. AiRO), windtunnel, or field testing, a fitter is simply using their best judgement and the end consumer is paying for their experience, exposure, and intuition on all things aero. The only catch here is that the naked eye (even with tons of experience) can be deceiving.
Would love to see if they have other tools that they’re deploying to virtually support the aero side of this equation.
Yes, did that and I can tell you that most of it is bs, cfd is not real aero testing. What cfd can do, i think/guess, is what interesting options would be to test and to see if it turns out as the cfd would expect it to be.
