Long vs Short Tail Aero Helmets: Which Is Fastest? | GTN Does Science

    Would be curious on some discussion and testing on visor versus sunglasses

  2. Bobby Silver on July 19, 2022 at 11:49 pm

    I have the drone. Sits nicely. Whether it is faster that my other helmet i’m not sure yet.

  3. StonegateCreations on July 19, 2022 at 11:54 pm

    Longtail all day. The tail touching my upper back reminds me to stay in position, plus I like the look.

    Met codatronca is an ace helmet, let’s you get away with stour head moving about, not too heavy and feels and looks great. Can still get it nicely tucked into your upper back

    I have the codatronca. With visor on, can feel+hear the wind flow pass better but for the distance I ride (avg 100km/ride), I find myself sweating buckets wearing it. The 3 holes in front are just too tiny and don’t do much in keeping the helmet ventilated to cool my head. The heat build it makes it steamy inside helmet and over time the fog does build up on the lense affecting my visibility. Should also say that my body isn’t flush flat with my head horizontally when I’m on tt bar. I’ve ordered Rudy Project The Wing and awaiting for it to arrive. I hope with the vent cover open, it will allow more are through my head as compared to codatronca so that I will feel more comfortable. Not sure how aerodynamics of both helmets compared but I believe they should be fairly similar and if there’s any difference it should be just really marginal

    I just like the pointier helmets better

  7. Matt Swainston on July 19, 2022 at 11:59 pm

    It seems to me that if you’re going to buy one helmet then you buy the short-tail. The long tail version only has a very small gain and even that’s only true in ideal circumstances. That said, long tail helmets still look cool!

  8. fabianbv82 on July 20, 2022 at 12:02 am

    I miss also the comparison with a normal helmet as the Met Rivale or Met Manta to see the difference…

  9. Mark Blackwell on July 20, 2022 at 12:06 am

    Why don’t you do one with an aero helmet and a normal helmet and see if it actually makes a difference

  10. Jack Graham on July 20, 2022 at 12:06 am

    Long tail = +10W for looking cool

  11. Nessunego on July 20, 2022 at 12:08 am

    For me a long tail helmet is a way of balancing my other long protrusion in the front of my body.

  12. Mike da Knight on July 20, 2022 at 12:30 am

    That’s why the old Kask infinity was genius. Short areo but also regular road helmet. If you can only afford one helmet, that was the one to get. You got to really be boss to get away with the long tail 😂

  13. Mach5sun on July 20, 2022 at 12:30 am

    Nice video! Could you do the same test with an off the shelf bike shop helmet that everyone has? I usually don’t train in my aero gear all the time I would be curious.
