First aero road bikes now aero road helmets. First companies were talking about how many vents they had now no vents. What’s your opinion?
companies desperately trying to differentiate themselves and make money?
same as it ever was!
Packaging tape goes a long way.
Maybe in cold weather, but try to wear this helmet on a long ride on a hot day and you will be calling the wifey to come pick you up off of the side of the road. We loose so much heat through our heads and hands. I don’t think it has enough vents for warm weather riding. Just my opinion. If I wanted to wear a helmet like this one, I would have taken up hockey…

I set a PR in a ventless helmet on saturday on a hot day.
maybe with an extended climb thrown in it would have been a problem. =)
How long was the ride, event? Assuming it was a tri.

The data suggests the opposite.

I haven’t been following ProTour as rigorously as in years past, obviously knew about the Giro Air Attack due to the feature on this site, however I was completely surprised to see all of the other teams coming out of the woodworks with vent covers on their helmets.
Didn’t realize it would spark such an arms race to plug up helmet ventilation.
Interesting, appreciate the share. Still not sure that I would ride or race a hot weather event in a closed helmet. I always thought that our hands and head (esepcially) is where a lot of heating and cooling occur.

The myth that we lose a lot of heat from our heads (in cold weather) is based on an old army study where soldiers were dressed in cold weather gear everywhere except their heads. In that case, obviously, a lot of the heat lost was from the head.
Is it just me or does that look like a hockey helmet?
Naw, it’s just you…

I haven’t run the analysis, but I’m pretty sure that 1hr is more than enough time to reach a stable body temperature.
At least the lack of vents keeps the sun off your head. Plus you need just enough airflow to enable sweat evaporation. If it’s >90F or so, you aren’t going to be losing much heat via convection.
What are you talking about, dude?
I was saying Jack broke the hour for 41k.
Sorry… a assumed that your comment had some remote connection to this thread.
Nope, sorry, just remotely related to a comment on the thread. Carry on…
That helmet looks like part of a Bumble Bee Transformer kid’s costume.
I know people that ride in 90-100 degree temps with hats or bandanas under their vented helmet, I can’t imagine this helmet is any hotter than doing that.
Get a Lazer helmet and a snap on cover. Pretty aero and you can leave the tape at home.
