I posted a bit ago to showcase the tangential possibility of creating an aerodynamic test from a video; after spending countless hours refining, building out a team, and a website all for this service, it’s finally here. [image] [image] Wind Tunnel AI Wind Tunnel AI …

Is the original video/photo of the rider in a static position? Meaning not pedaling? My concern would be that alot of people can put themselves in a static position that they can’t hold while pedaling.

It is a static position, however, this is a solid point, and I may update the “how to” section, as I could add the instruction “for position testing, first start on the trainer while pedaling, when settled into a natural position that is likely aero and can be held while pedaling, cease pedaling and…

Since this is static, what would be the best leg position for the rider? Top of the pedal stroke (6/12 o’clock), mid stroke (3/9 o’clock), something else?

Just a reference to my question in your previous thread. Maybe you want to play with that idea? [image] 20 sec video to full on CFD AERO test! Equipment Kudos…you need the right idea at the right time and we have a next David Tinker here (intervals.icu). Your cervelo mod…

Yeah, I’ve been very busy, will it show a difference? probably, could I go and try it, yeah, hold on.

I’d imagine mid pedal stroke, feet aligned parallel to the ground, but as long as it’s static and the same it shouldn’t distract from the overall form/other changes to a noticeable degree. We do have an aerodynamic specialist on the team and he’s advising on those particulars. This is why we’re in …

Okay, would have been faster but I was hungry… So, I don’t have the bike model from the other thread, I deleted it at one point. So I just used this one: [image] I got rid of the wires outlined. Now, to be fair, they are a tiny bit bigger when I from points to mesh (still attenuating that part…

Thanks a lot! That is so amazing yet disappointing at the same time. 4 cables less and not even a single watt gained, that’s hard. Suddenly my desire for a new bike with a slick cockpit has vaporized…I was hoping for new records :smile: Not sure what the difference of an integrated cockpit vs stem…

0.226 is pretty fast. Can you scale this gravel bike to a pro tour spec TT bike? Would prob be pretty low

For reference, the rider was my twin, we’re both 5’6", and, as you can likely guess, obsessed with aero gains, and that’s the most aggressive position I could get on that bike, aerobars under handlebars, short, -30 degree stem, seat froward, tilted down etc. I actually have a full TT setup I use fo…
