how much for a vowel?
Buy the Lazer and sleep well at night knowing that you at least considered the fact that it was an unnecessary purchase. If ever a pang of guilt takes hold, just look at your avatar and remind yourself that existence is absurd so it probably doesn’t really matter that much in the grand scheme of things.
cuddles at the giro currently, guess the less ventilation would be handy in the colder/wetter weather. Aero is just a bonus =D
some some bloke with a giro aero on a shitty single speed today. It has begun.
maybe just a skate helmet?
or aero aero??
no the new shit ones.
I saw a middle-aged, pudgy roadie in full lycra wearing a skate lid last week. Maybe he’s ^ fixie dude grown up. Bummed I didn’t get a photo.
Seen a roadie recently commuting on the Gardiner Creek Trail with a Giro aero lid…
Retro:
Perfect.
I’ll look into it when I move back to Perth next month. I’m not taking two helmets on the plane with me, haha.
I bought a Bell today then immediately ruined the aero by fixing a peak. I like a peak for commuting and just cruising.
I’ve been shopping for a few weeks now. I take a small size and it shits me when salesmen try to sell me a big helmet that’s been adjusted in. Sure the internal frame can be dialled in but if I don’t need a big shell then why buy one?
BTW, what’s the point of a Carbon shell? Serious question. I know carbon has huge tensile strength but helmet materials need impact absorption not tensile strength. I would have assumed that polystyrene has better impact absorption properties than carbon.
To be honest it’s just for looks, but I guess it may help hold the helmet together at impact.
I’ve been caught up in some big crashes but avoided coming down and the helmets were a shock, most broke into pieces.
After a bit of googling, which I probably should have done before I asked the question, I found that the expanded polystyrene does all of the impact absorption, any carbon or graphene outer shell is supposed to prevent penetration by sharp objects.
Here’s some links if anyone is interested.

so the infinity’s are in stock, bikebug has em for $350, LBS has em for $400.
Tried them on, fiddled with them, and for lack of a better word, they feel kind of flimsy. The plastic bits covering the vents, and the front adjustible ‘vent’ feel cheap.
I understand its made thin to keep it lightweight etc, but i dunno.
Dosnt look or feel bad once on though
But would rather spend $300 on the new matte black vertigos to be honest.
POC Octals also come in an aero version, evans currently having stuff at 20% off, meaning the regular poc octal lids are about $325 posted
while the octal aeros are about $360 posted

Local retail will be $340 on the octal and arrive July,
Don’t think Australia will get the aero version this year.
yeh, i saw on bikeexchance a few going at $350, so good to see the pricing is consistent nationally.
This image of a cyclist on a triathlon bike is a visualisation of the CFD calculations. Yellow and white areas on the cyclist and bike show regions that have the highest drag. The cyclist himself accounts for 72 per cent of the drag force, with his legs generating most of that. The frame and forks account for 5.7 per cent, and the gearing 5.2 per cent. Water bottles are lumpy and generate 4.5 per cent of the drag. External cabling makes up 3.8 per cent, which makes a strong argument for tucking it inside the frame. As for the ribbons streaming behind, the white lines indicate high-velocity airflow and the pink-blue lines indicate slow-moving regions.
Giro Synthe available from Evans, not cheap at $343
