Ironman USA Lake Placid : Official Thread (Page 134)

A Ferrari..........

Maybe its just a mid life crisis thing

The anlalogy is not terrible.  Aero helmets (like high end sports cars) are built for Speed. My Limar Speed Demon Aero Helmet is much lighter than my Bell Giro.  My Limar Speed Demon helmet is also entirely open in the back.  When I wear that helmet, from my base of my neck to the top of the back of my skull is NOT covered by any protective material; just a strap.  On my Bell Giro helmet there is foam and a thick composite guard that goes right across the middle back of my skull.  Also, when looking at the front of the helmet that covers the forehead, there is considerably more foam padding on my Bell Giro. 

So, for me, common sense alone tells me my Giro road helmet is safer.  And here is a memo from a Professor at the Bicycle Helmet Safety institute citing the potential dangers of teardrop-shaped Aero helmets:   http://www.bhsi.org/hurtmemo.htm

Mainly, the comfort of sleeveless due to less restriction in the shoulders....

Oh, on my  long ride this weekend, I practiced staying in aero at 50+ mph.  It was a bit unnerving at first but so much fun.  So it looks like the Keene descent will be done in aero all the way.

I figure if my Blue can track through sweeping turns at 50+, it shouldnt' be a problem come training camp.

When the guy in front of me hit that deer, on a downhill, going around 30MPH, and his head hit the pavement, it was the bottom of the helmet that cracked and saved his life.  The bottom of the helmet right by the base of his skull.  Had he been wearing an aero helmet, I can't help but wonder the inherent likelihood that the helmet would have twisted, perhaps possibly ejecting of sliding off his head and exposing his skull or twisting his neck.  The SHELL OF THE INSIDE OF ALL HELMETS must meet the same CPSC requirmentsl; however, it is the design of the outside that may cause the head, neck or hlemet to twist.  Common sense tells you a long point hitting the pavement is not going to act as predictably as a round shape hitting the pavement. 

 I can't get his song out of my head.  http://www.youtube.com/watch?v=y_SI2EDM6Lo    For my long Swims and Bikes I hear it over and over.  Driving me mad!!
