    1. Looks like shoe covers. Maybe laced shoes under to get turbulence
    2. Ceramic speed aero derailleur (expensive option)
    3. Different helmets
    4. Aero calf sleeves
    5. One piece arm extensions
    6. Clean up cables
    7. Water bottle in jersey
    8. Not sure tire choice but something to play with
    9. 1x set up
    Thinking from a triathlon perspective not sure type of racing

    Having raced Louie for around 25 years, I can confirm he punches a very small hole in the wind. last wknd in a road race, me, him and two others off the front. Me behind him in the rotation. Drat!

    Wow that is an incredible CDA. You have a little Remco there! It’s neat to see him accomplishing this with older school equipment. I’m curious about those Nopinz overshoes. My only experience is with the Castelli ones. Thankyou for the videos, they are very informative and I’m applying some of the knowledge to my position.

      @@Shadowboost Based on what? His numbers aren't public but if someone like Bigham can get a .15 (even getting into the 0.14x for shorter runs) on a track bike and should be low-mid 0.16x on a road TT bike, Remco who is 12cm shorter than Bigham being similar in CdA would be expected. Also Bigham makes Louie look like trash CdA wise considering the 28cm height difference.

    Great video. Some thoughts based on aerodynamics background/triathlons: 1) Could try to move hands slightly closer to close gap between hands (particularly the lower part of his grip where the finger knuckles could touch) ... balance of higher stagnation pressure versus area 1b) aero gloves since hands are the first contact or tripping point for flow separation... this might help to keep the streamlines close downstream of the hands 2) would try stretching the reach out a bit to lower overall upper body profile 3) with the high forearm angle, the tri bar underside/arm pads need to be cleaned up (custom molded perhaps, and even a one piece solid dual elbow pad configuration) as this area is more exposed in his extreme arm angle position.

    Try the new swissside calf sleeves? Horizontal ridges instead of vertical on most other brands. Whether that makes a difference or not, only testing will show... Decent Whitepaper on their testing regime too...

    Magnus Ditlev and his aero tester probably won’t ever release his numbers but with some math putting his power and speed together people have estimated he’s around .20 on a few occasions. He has said his handlebars made a noticeable drop in his cda so I feel like this guy can get to .14 with some custom molded bars, a water bottle on his chest and hidden cables.

  • @michaelmullen2617
    @michaelmullen2617 8 месяцев назад +3

    Nice video, although I think the rider could definitely be a lot more aero. I'm at .157 CdA (consistently) measured on my Aeropod. Old rim brake Shiv TT, HED 3+ trispoke, Roval 321 disc, TriRig front brake, 15 degree risers, mechanical 10-speed SRAM Red, standard Specialized cranks (172.5). I use a POC Tempor or Giro Aerohead depending on wind conditions, and also change tires depending on road conditions, running 70/72psi front/rear. Your rider needs to get his head down more, straighten out his back, and close the gap between the extensions and his chin.

    • @mikehorst5252
      @mikehorst5252 8 месяцев назад

      Agreed. I think his hands are actually too high, forcing him to lift his head to see over them. Not a great head to back transition.

  • @nizerp
    @nizerp 8 месяцев назад +1

    Switch from Michelin Power Time Trial to the new Vittoria Corsa Pro Speed should reduce watts. Technically more of of the gain is from CRR not CdA. These can be estimated separately because CRR is constant and CdA is exponential relative to wind speed. Switching to 1x, also. The Tempor is "tempormental", but looks like it might work with his position and shoulder width. The Specialized TT5 seems to be less temperamental.

    Frontal area has a large effect on "A", but so does surface area and surface finish. As such, it's best to leave CdA as one number and not try to separate the two.

    • @Shadowboost
      @Shadowboost 8 месяцев назад +1

      Surface area and finish have no effect on A. The reference area in this is the frontal area. The CD is affected by those, specifically, the skin drag component

  • @neilmdon
    @neilmdon 8 месяцев назад

    Is the “constant area rule” from supersonic flight relevant? I actually teach fluids and don’t know the answer. In the front on picture where you are talking about his elbows in, his quite beefy thighs are obviously contributing to A, but I assume that at least keeping the change in area as you move backwards through the system (dA / dz if you want to geek out) is going to be relevant, and I surmise that you do NOT want area to go up (as it must from the tip of the tire) to a maximum (which it must again) and THEN BACK DOWN AND UP AGAIN. I presume that hourglasses are slow, but I am not sure how those potential pockets of air with turbulence outside will affect overall airflow.

    • @Shadowboost
      @Shadowboost 8 месяцев назад

      No, it's not. Interference drag is the biggest part to minimize. You're in the low Reynolds regime, hiding the legs, chest, shoulders is the important bit

  • @squiresuzuki
    @squiresuzuki 8 месяцев назад +2

    6:48 ...isn't it important that the sensor doesn't bounce around like that? If it's constantly changing how the air flows into the tube. At least that's what the instructions for my Aeropod said

    • @fastorfiction
      @fastorfiction  8 месяцев назад +2

      Two things...The spot where I stand to take photos and video is a bit bumpy and not actually in the test area. The AeroPro, though, is not susceptible to the bouncing issue (within reason of course). If it were, we wouldn't be able to produce consistent results. It's why I use it. I've only found two sensors that are worth using and this is one of them. The other is Swiss Side's.

    Most people don’t see how big of a CDA difference between a UCI legal position and not. With the UCI rules applied, I argue 99.9% of riders won’t even make it near .16. In addition, being a smaller rider and riding at a hunched position is a pretty poor combination to attempt to take on bigger more powerful riders, (as an opinion of my own)

    • @Xhadp
      @Xhadp 8 месяцев назад +1

      This is something he can explain. That isn't necessarily true because he left out a very important part of the CDA equation, velocity and more specifically what is attached to it. It is squared so that means that it becomes harder to exponentially generate more power to move faster. Plus in a triathlon there is still a running portion so you don't want to use up all of your power on the bike section which he mentioned in his Wout Van Aert's position analysis where he only has to do a (UCI) TT on a bike.
