This post is about the Bontrager Ballista.Here's the Ballista in yellow, if by "yellow" you mean "chartreuse," which is the color both Sam and I have.

Aerogeeks continue to report a real weight of 272 gms, not far above a true road helmet. The S-Works Prevail, high-end road helmet that does not purport to be designed to optimize aerodynamics, claims a weight of 214 gms. And the low-end Specialized Echelon is reported by Specialized to weigh "about 305 with out a visor".
What it replaces.My own aero helmet experience includes Giro's early offering in road-friendly aero helmets, the "Air Attack," and two time trial helmets in the sperm configuration.

The Giro Air Attack, below, is both heavy and hot. In fact, it appears the primary benefit is that it makes the wearer look mean. Which is no small benefit, of course.

|No, not me, but it looks aero. From American Flyers.|

|Lots of other things hurt, but the head was fine.|
I have to take the aero benefits on faith. Visibility benefits seem to be real based on the below picture.

So, a truly wearable helmet that supposedly makes me faster. Number five on my list of favorite new gear for 2015.
