When it was introduced, the Storck Aernario represented a significant leap forward for the German masterminds — namely an aero road bike that was comfortable and rode brilliantly. Not content to rest on its laurels, Storck has introduced the Aernario Disc, and in so doing, raised the bar for endurance road bikes. It benefits from the same aerodynamic efficiency and balanced handling, and adds disc brakes to the equation. But far from being a stopgap measure, this new frame was designed from the ground up to provide even greater advantages to the discerning rider. If you’re familiar with aero-frames, you’re most likely aware of the drawbacks that normally plague the category — namely questionable aesthetics and a harsh ride. However, Markus Storck refused to accept the status quo, and he created what Storck calls “sectional aerodynamic shaping.” Think of it as an aerodynamic profile on the horizontal plane. By this, we mean that the Aernario’s teardrop profile takes shape horizontally rather than vertically. In other words, if you were to take a cross-section, its aero-shape would become strikingly evident. However, the aerodynamic advantage is hidden by a characteristically beautiful silhouette. As with its rim brake-equipped cousin, the Aernario disc was constructed from Storck’s own CFR/UD carbon fiber. Compared to a woven carbon fabric, unidirectional carbon is oriented as it sounds, with one direction, or on one axis. Unidirectional fibers tend to better stiffen frames, while also improving the characteristic of vibration dampening. And through a refined layup, this is achieved at a much lower overall weight. It’s worth noting that the Aernario is, in fact, molded in a monocoque. In other words, it features a one-piece molded construction. This eliminates excess weight by requiring less carbon and resin application at the tube junctures of the frame. In designing the disc version, Storck was far from content to simply add disc mounts and call it a day. Per…
