I was flipping through the Excel catalog and saw a listing for a new aerodynamic helmet, the Louis Garneau Prologue. It claims to be "the one and only aero helmet on the market that is certified and racing legal." Does anyone know anything more about this helmet?
Also, Briko offers an aero helmet as well, the Crono. If the Garneau is the "one and only," does that mean that the Crono is not race legal? How would I go about finding out more about either of these helmets?
