Mavic have long lagged behind the rest of the wheel market on the aerodynamics front, instead coming out with rather dubious ”features” that created some of the slowest high end wheels around.
Some time in the last couple of years someone at Mavic had an epiphany… “our customers want fast wheels!!” (maybe they got tired of bikesnobnyc making fun of them)
Thus, they claim to have spent 400 hours in the wind tunnel in the past year. The new CXR80 wheel/tyre system is a product of this revised focus and has a lot of promising features.
