For Mavic, 2013 stands to be a massive year of innovation. And if you"re running a new Mavic wheelset with CX01 Technology, it"s going to be a massive year of aerodynamic advantage for you. The reason is simple, and if you forgot why you purchased a wheel like the CXR 80T, let us remind you. To increase laminar airflow, CX01 completely integrates the tire and rim. And we should note that this doesn"t only smooth out the flow in the straight ahead position, instead, the system provides +/- 5% aero gains at every yaw angle. So, if you"ve somehow misplaced your CX01 Blades, we"ve got you covered with the Replacement CX01 Blades - Set of 4. Please note that these are compatible with the Mavic Cosmic CXR 80T wheelset.
