The craziest helmet of all time!?

[@JW-hj6sd]

POC - Star Wars White Lord Vader:P

[@ronykuba]

Haha

[@GrahamRHowell]

I've always thought it would be super beneficial to find some strong coin sized magnets, glue one to the underside of the tails of the helmet and find a way to fix another to the appropriate spot inside the speed suit (possibly a small pocket sewn inside or use a suit that has a radio pocket built in). The magnet wouldn't be so strong that you're fixed in position but it would be a super easy way to located the correct position repeatably every time and help encourage the correct position under fatigued states to ward the end of a tt. What do you think?

[@ronykuba]

I want to try this myself

[@GrahamRHowell]

@@ronykuba if you get a chance to test it let me know how it goes. I'm planning on trying it with a 2nd had Lazer Wasp next week.

[@adamtaylor3987]

Pretty sure Emma Pooley said she did this on GCN when she was a pro

[@GrahamRHowell]

@@adamtaylor3987 Just went looking for it and yeah she said she used to do it in training to encourage the position. It's at about 13:15 in the video below. kzbin.info/www/bejne/gHrQZXytqMd8r7c

[@jongminkim9538]

I wear a Kask bambino that has really flimsy plastic siding for ears. Makes a crazy whistling sound when you go fast. the visor is flimsy as well

[@detmer87]

That's one fast turtle :P

[@ronykuba]

Hopefully!

[@2906rick]

Is white the only color? I would prefer black. It does look dorky but it looks super fast. Waiting for your cda test!

[@ronykuba]

There's white and orange. Me too!

[@hugoforssell1288]

The helmet was made for the 2012 olympics, but not for the track nor the Danish squad. It was made in collaboration with and for the swedish cyclist Gustav Larsson (who won the 2008 olympic ITT silver medal). However it was also used by the rest of the swedish team during the olympics, but only on the road because Sweden did not have anyone participating in the track events.

[@ronykuba]

Ok thanks

[@robertgreiner4703]

i tested 3 helmets. Somehow POC Tempor ans Mistral have same outcome for me. Only the MET Drone seems to be slower

[@ronykuba]

Thanks for sharing

[@marty197666]

I thought the point of the vents was to create an exhaust that smooths out the airflow over the back?

[@ronykuba]

Nope. There's no exhaust at the back.

[@adamtaylor3987]

It comes out of the vents on the sides to speed up the airflow over the deltoids. The bottom half of the vents cools the head which may exhaust under the tail, hence the insert that is blanked off, in case it’s a cold day. Which may suggest having it slightly off your back? Not sure.

[@orbdayan]

Hi ! Really love your videos… I have a practical question- I wonder if you can lower the ratchet closer system lower? Did you do it? I am afraid to harm it when pulling it out. Also - What combo of liners did you use ? Seems like the extra liner + the thin one. Thanks!

[@ronykuba]

Hi, thanks for the support. I only use the thin liner. The cradle can be moved.

[@juanangomeztri]

Hi Ronald ! I buy this helmet and I try few days ago… I have a big problem, when I’m riding fast maybe in a downhill more than 50/55 km\h the helmet is flying back… I try the different fits inside but still with the same problem. Can you told me if you have the same problem ??

[@ronykuba]

no, I don´t

[@timtaylor9590]

i thought lines where supposed to be perpendicular to the air flow not parallel to trip the air.

[@yannickokpara4861]

The POC looks to cover the gap between your neck and back much better even when you are not adjusting the helmet as in the video. It also looks like the sides would give a better transition of the air to your shoulders and back in general. It really fills in those nasty gaps quite well. I do wonder though if you would be better off raising the front end slightly to bring your shoulders higher up around your head if it doesn't also lower your back relative to the helmet tail even if it is no problem comfort wise to maintain position currently. Perhaps a couple of watts extra in power with this too and some extra benefit on rolling terrain.

[@yannickokpara4861]

How do they compare though in terms of visibility I wonder?

[@ronykuba]

yes it looks like that, as for the stack, that is why we do aero testing :)

[@tybobab]

Do you know the cda with poc helmet and with Kask helmet ? And, with your eight, are you max forward at 80cm and 5cm setback or less ? Thanks for your videos, very great and smart subjects

[@ronykuba]

Not yet. You can't have 80cm of extension and less than 5cm of setback at the same time. My setback is around 65mm and the extensions are at 76cm.

[@torbis75]

Do you have a video with the aero testing of it?

[@ronykuba]

no

[@ankitkbd]

No longer using sub 6's for tt? Where are the socks from?

[@ronykuba]

I am

[@pabloldv5911]

not related to the Poc helmet, but how often do you change Speedplay cleats?

[@ronykuba]

1x/year

[@fuzesydavid9614]

What happened with the Bambino PRO EVO? Maybe my mistake, but I couldn't find any video from it after your first one. Of course it's almost impossible to get one, but I'm curious what was your opinion.

[@ronykuba]

It performed exactly the same as the Mistral, so I didn't keep it.

[@michaelkennedy9064]

In anIronman yes the intensity is lower in comparison to an all out time trial but its how your body goes getting off the bike to run a marathon. The one other major factor with an Ironman course is you can't ride with your head down because the course is littered with people

[@ronykuba]

I did ride an IM head down

Always wanted to be a fast cyclist, with all the gear. always wanted to ride on a track, never had the chance. Great looking helmet, think I’m too old too fat now, but i can still lust after owning one

[@josemedina-jj7pp]

Great video Ronald! I been following you for a few years now and learned a lot, keep up posting, do you happen to know how wide that tempor is? I’m a small rider my shoulders are 33 cms when tucked! I wonder is this helmet will work with my shoulders or if it’s to wide! Thanks a lot for sharing your videos!! 👍

[@abcdecghijklmn]

I never forget the 1st time I saw the Tempor! 😮

[@noahfontaine7832]

The vents are only there to serve as an exhaust if there is one at the end. If there isn’t, it’s only for ventilation. There’s NO way the air would split at the front due to the high pressure under 150 km/h

[@ronykuba]

Firstly that's wrong, secondly the exit points are on the sides.

[@noahfontaine7832]

@@ronykuba So then it serves as an exhaust so smoothen the airflow on the sides. Creating vents without exhausts automatically make them slower as the cd increases. Furthermore it is impossible for smooth airflow to split at cycling speeds with that shape. There is absolutely no way you can reach that high of a pressure at even 90 km/h with this type of airfoil.

[@ronykuba]

@@noahfontaine7832 uhm

[@olivermullen3952]

Ronald, I have already done aero testing on the POC Tempor versus my Giro Aerohead setup on the Trebesin outside velodrome in Prague. The Tempor was much faster. I have the details on my most recent Strava post (username Michael Mullen). It’s a post, not an activity. Good luck with your testing.

[@ronykuba]

Sounds good!

[@davidahlen2886]

I’d be very interested to read that post and have added you on Strava. Cheers!

"POC", the sound heard when you slam into whatever is in front of you. 🤕

My forearms have not grown together yet and are two separate units, so there's no need for concern

@@sylvainmichaud2262 as I tried to explain, I can see everything in front of me through the gap between my forearms. I have been riding like this for the past 2 seasons and never had an issue, even in 4h TTs.

[@andyg9991]

Shame you couldn't get a front on view of each helmet. Would be interesting to see just how much more of your shoulders the POC covers, but it looks like it could be very fast for you You've obviously spent a lot of time and effort dialing in your position. Do you know what your CdA is or is it a secret??

[@ronykuba]

Next time! With the last test it was 0.172, hoping to go sub 170
