The Story:

The M5's are the perfect blend of a performance and price. They are the next generation of carbon road wheels in the ever-popular M-series. 


The M5's construction uses Mercury's Dual Carbon Layer Process, or DLP. DLP blends high and mid-moduli carbon fibers to tease out the best balance between the lightweight and stiffness of the former and the fatigue-resistance and durability of the latter. DLP also involves the incorporation of high-temperature resins in the brake track to reduce heat build-up and increase stopping power. This increased stopping power goes a long way toward addressing the poor braking that is one of the most common critiques of carbon wheels.


The aerodynamic benefits of a deep dish rim are further complemented by Mercury's Seamless Transition Technology (STT), which integrates the brake strip with the rest of the rim in order to eliminate any obstructions to wind flow and reduce drag-causing turbulence. The result of this construction is a wheel that balances the above qualities with considerations of weight for our most popular wheel by far.

Spokes + Hub

The M5s are finished off with Sapim's indefatigable CX-Ray spokes and Mercury's own hubs. The rear hub includes multiple pawls for an engagement that's as close to immediate as anything we've seen on the market today, and the front hub has an extra-wide 70 millimeter flange for reduced flex under hard efforts and confident stability at speed. Both hubs have an oversized axle that reduces to accommodate a traditional quick release and two and four oversized bearings in the front and back, respectively.
