This is Chris McCormack, a good Ironman athlete. Notice the numbers on his arms, and the bladed shape of the bicycle frame. He has chosen to use a three spoked wheel at the back, which has a bit more momentum and is a little heavier than the light and aero deep section wheel in the front. These wheels are also high quality and are made by a company called HED. HED and ZIPP are a bit like BMW and Mercedes Benz. Is that a smile or a grimace? You can also see that Orca is a familiar name to many in this sport.
