BIG WHERE IT COUNTS

Possessing twice the tensile strength of High-Modulus carbon fiber, Fiber-X employs damping characteristics to deliver a trail-tuned ride while increasing durability - durable enough to withstand a double impact of 120 joules at the same location. The Fiber-X material is blended into all of Mercury’s X-Series wheels and is visible by its distinguishable silver stripe. Rim profiles feature an optimized Radius profile that funnels trail input into the damping material to dissipate energy and avoid failure. At their center, is Mercury’s proprietary delivering 7.5° of engagement. All current wheel diameters, axle sizes and freehub standards are supported.

World's Fastest Wheel™

Born and crafted in an aerodynamics lab, the A5 comes in at 55mm deep, but offers a virtual depth of 67mm by utilizing Kamm Tail Technology.

Kamm Tail Technology gives the A5 the aero benefits of a 67mm deep wheel, while still maintaining a lower profile. From the wind tunnel to the podium, no other wheel on planet earth offers this combination of light weight and aero.

See how independent engineers proved this by testing computational fluid dynamics, comparing the world's best wheels (photos 10 and 11).
The A5 ranked #1.

Race Edition

This A5 Race Edition includes a more advanced 5-axis hub with higher engagement and lower friction.

M5

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. 

DLP

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.

Aero

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.
