At first blush, you might be inclined to compare Mercury's M3 Carbon Clincher Wheelset to other manufacturers' pure climbing wheels. And you'd be right to do so, at least when it comes to climbing. But these aren't just a one-trick pony. The M3s' aerodynamic pedigree, low weight, and brute strength also recommend them for all the ups, downs, and flat-outs of competitive cycling. They cover the demands of every terrain on every day of your cycling life.

The rims measure 38 millimeters, a depth that strikes an all-purpose middle ground between straight-on aerodynamics, hiding from crosswinds, and considerations of weight for climbing. The M3 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.

included in the box
