What matters is not power [Watt] but torque [Newtonmeters]
Engineering in Cycling means that all aspects between human and machine are analyzed and improved for the purpose of optimizing performance.
In this lecture from November 22, 2011, Dr. Eoghan Clifford lists all of these aspects that today are a prerequisite for absolute top performance in road cycling. So today's engineers are required to develop wheels and measuring technology in addition to the knowledge of aerodynamics and design which support the best athletes in their effort to the maximum...
