I will snag the Giro air attack w/lens as soon as it comes out, looks OK for cooler ride days and should give some advantage in a 25+ mile race.

My Specialized Prevail is also supposedly (amongst other things) an aero helmet. I can't see it either.

This one doesn't require any mid-race trips to the car, and even reduces total weight!

Yup. Since we're primarily talking about pressure drag, they just need to push the separation region as far back as possible. TT helmets and tube profiles are now using less streamlining and more boundary layer manipulation to lower the pressure drag. The vortex vanes on LG's vortice helmets and the 'tripwire' on BMC's new tube shape are examples. They just need to keep the flow attached to the helmet.

I know enough of aerodynamics to understand there is more than making it look like a tear drop

But that said I think the Carrera looks completely generic... not different than the average Giro. I'm sure I'm missing something, but the problem is that only a few salesmen put it up as aero, Carrera themselves seem rather sparse with info.



Nice words, but best compared to what? Best of every road helmet? Best Carrera?

Not saying other manufacturers don't do the same thing, but with LG and Giro I can see the differences, this helmet looks amazingly generic. But hey, if it works I'll be in line buying one as it sure looks less silly (I need that as I am just pack fodder).

Hell get that Kask TT helmet! I'm sure it would work both ways even without the visor!

The Kask is great but not $500 great unless racing.

Guys, couldn't I just put a condom over a helmet?

Anyone heard anything about that second helmet? I just got a Bambino and I don't think you would want to use it in anything but a time trial.

Put a 0.02mm so that no one will notice

Awesome. Nice to try one day but unused
