At the price it makes you wonder! I'd expect to get a little man servant named Helmut with such a nicely priced helmet...
I sent an e-mail to British Cycling asking what the price for their aero helmet was. The helmet is to be used in the Olympics, and therefore has to be available for the public to purchase. Now I am wondering what their frames are selling for
