The M50's have seen countless podium finishes on varying courses. They are light enough to handle the steepest of climbs yet deep enough to provide you with an “unfair” aerodynamic advantage on the flats. Bottom line, the M5’s will bring you to the line alone. It is up to you to decide how to celebrate the win.

The M5s' construction is informed by the Dual Carbon Layer Process, or DLP. Mercury blends high- and mid-moduli carbon fibers to straddle the best balance between the lightweight and stiffness of the former and the fatigue-resistance and durability of the latter. 

The M5 is a solid 24mm wide, which means you can run lower PSI for a more comfortable ride that corners with unparalleled confidence. Wider rims also have some counter-intuitive effects when compared to those standard 19 millimeter rims: they actually decrease rolling resistance and increase aerodynamics.
