Description

Best of all worlds.

Storck designed the Aernario Road Bike Frame with one principle in mind -- balance. Basically, Markus Storck strove to seamlessly mate the aerodynamic frame design of its Aero time trial bikes with the rigidity, handling, and comfort of its Fascenario 0.7. We would say that he succeeded.

If you're familiar with 'aero-frames,' you probably don't own one, because you either loathe the aesthetic or find that watts that you save in drag reduction are tacked back on by poor power transfer and handling. To alleviate this problematic syndrome, Storck created what it calls 'sectional aerodynamic shaping.' However, it helps to think of this as an aerodynamic profile on the horizontal plane. By this, we mean that the Aernario's teardrop profile (NACA if you're savvy) takes shape horizontally rather than vertically. So, when viewing the frame from the side, it looks like a traditional road frame. However, if you were to take a cross-section, its aero-shape would become strikingly evident. In addition to the tube profile, Storck also improved aerodynamics and comfort by cleverly hiding the seatpost bolt under the top tube. By doing this, the tube shape is further streamlined, while shortening the seatpost increases comfort. Accordingly, the Aernario sees nothing but gains on all fronts.

As for the carbon fiber, itself, the Aernario was constructed from Storck's own CFR/UD carbon fiber, with the UD designating 'uni-directional.' Why uni-directional? Well, compared to a woven carbon fabric, uni-directional carbon is oriented as it sounds, with one direction, or on one axis. And while this makes the production process incredibly more complicated in regards to load path and force direction determination, the payout is worth it to Storck. You see, compared to woven layups, uni-directional fibers tend to better stiffen frames, while also improving the characteristic of vibration dampening. And incredibly, this is achieved at a much lower overall weight. However, Storck was far from finished in any of these regards.

Let's approach the Storck layup process in a short series of steps. First off, Storck begins the design with 3D CAD imaging. This digital process provides Storck with the precise data and dimensions necessary for the development of the mold. From there, the CFR/UD fibers are soaked in resin and hand-placed into the computer-generated mold. Once placed in the mold, the fibers are heated and pressed into place with an air channeling tool. Afterwards, the fibers are smoothed over by hand, ensuring an unprecedented level of preciseness and detail to the layup.

It's worth noting that the Aernario is, in fact, molded in a monocoque. This means that the Aernario is comprised of specific modulus carbon fibers throughout the frame, or 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. As a result, at around 890 grams, is actually lighter than the Fenomalist, and is fast approaching the halo weight category of the BH Ultralight and Ridley Helium SL.

Moving into frame specifics, you'll find a massive, oversized PressFit BB86 bottom bracket juncture that efficiently transfers power to the rear triangle. And not surprisingly, we see the reoccurring theme at work again of increased weight reduction coming as a result of increased power transfer. At the seatstays, Storck gracefully originates them from a box-section above the brake caliper. And again, this results in increased comfort via vertical compliance, however, it also directly equates to a higher level of lateral rigidity. Additionally, you'll find that the Aernario is one of the most painstakingly rider-tuned frames on the market. This is due in part to Storck's proportional tubing concept, where every frame size uses adapted dimensions, wall thickness, tube diameter, and tapering to ensure the exactly intended ride quality regardless of size. Rounding out the construction is electronic-drivetrain-specific internal cable routing.

For the fork, Storck incorporated its latest iteration of the trend-setting and award winning Stiletto, the Stiletto 340. The first version of the Stiletto was introduced in 1999, and was widely hailed as the lightest fork on the planet. And while the Stiletto Light only tipped the scales at 280 grams, the 340 gram Stiletto found here is still lighter than most of the featherweight, aftermarket forks. The 340 features a tapered design that's been mated to a carbon reinforced heat tube and a 1-1/8 - 1-1/4 inch integrated headset.

Altogether, these technologies, paired with an unrelenting dedication to hand-built perfection, create a frame that's balanced, lightweight, compliant, and most importantly, fast.

The Storck Aernario Road Bike Frame is available in the color White/black and in six odd sizes from 47 to 63cm. Please note that this frame uses a PressFit BB86 bottom bracket and a replaceable CNC-machined aluminum derailleur hanger. Additionally, despite being electronic-driven, the frame routing is also compatible with mechanical shift systems.

Storck Aernario Delivers!

  • Familiarity: I've put it through the wringer

I was looking for a road bike that was both aerodynamic, stiff, and responsive. Usually to get all the above means you have to sacrifice comfort. Not the case with the aernario! The first time I took my new bike for a ride, I immediately noticed how responsive it was when climbing. It felt like someone gave me a push of momentum from behind and I loved the feel of the stiffness that the bottom bracket offered. Not only does this bike make climbing fun, but descending is even more enjoyable. I feel solid on fast descents and love how the bike handles on turns. When descending on my previous road bike, I could feel when speeds approached 45+ mph. On the Storck, I run out of gears before I look down at my speed because of its solid feel and aero handling. I love how the Aernario handles and makes me feel more confident on the bike.....not to mention FAST! Well worth the investment.
