The Abus GameChanger Aero Road Helmet has become my favorite helmet since I bought it. I bought a second one for good measure recently. Beyond liking the shape of the helmet, I appreciated the air flow pattern and the coverage from the direct sunlight. My head does not overheat on the long rides. So far, this summer, I have done three 4 hour + rides with the white and one with a black helmet as my ride sample size. I do not ride fast enough to validate its areo benefits, but its a cool helmet for my needs.
