Welcome to the future.

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. Perhaps the most noticeable design feature is the rear thru axle, which we’d like to see become standard on disc road frames. In addition to providing added wheel retention, it makes for a much stiffer dropout configuration. And that additional stiffness, combined with the fact that braking forces are no longer transmitted through the seatstays, allowed Storck to use an even thinner, more compliant seatstay than the already smooth riding Aernario. It’s a perfect match, as disc brakes lend themselves to the growing “endurance road” category, and the disc version’s redesigned seatstay only enhances the all-day comfort.

Moving into frame specifics, you'll find a massive, oversized PressFit BB86 bottom bracket juncture that efficiently transfers power to the rear triangle. But that stiffness doesn’t sacrifice rider comfort, due to Storck's proportional tubing concept. It’s a way of saying that 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-compatible internal cable routing, although it’s compatible with mechanical drivetrains if you prefer.

For the fork, Storck’s award-winning Stiletto has been further improved in the form of the Stiletto Disc. At 400g, it’s as light as many lightweight aftermarket forks and astonishingly stiff, especially under braking. The 340 features a tapered design that's been mated to a 1-1/8 - 1-1/4in integrated headset.

I'm thinking of teaming up with Di2 Group set. Can junction B be installed even if BB is installed first?

Love this bike

I've put it through the wringer

For the past 5 years or so my main road bike has been a custom titanium road disc. This was a bit of a gamble back then, as no one really made a road race geometry frame with disc brakes. But it sold me on discs from the first ride. It has been upgrade multiple times over the years and is similar in spec to my new Aernario (which is built with DA DI2, r785 brakes, Pioneer DA powermeter, and Enve 5.6 wheels). I love my old ride (and it will remain my wet weather bike). So much so that I was somewhat conflicted about buying a new bike. But the Aernario is better in so many ways. Stiffer AND more compliant Yes, it absorbs bad roads and huge root bumps at speed better and it is stiff as a steel beam when I stand on it. The aero gain is also apparent - I'm a gear faster at the same cadence and power on a variety of stretches of my regular routes. If you are considering this bike, you will not be disappointed!

Stiff, fast, awesome

I've used it several times

As a rep here at Competitive, I get to ride our bikes sometimes in rapid succession. This allows me to compare bikes in real time while the last demo is still fresh on my mind. I finally got my hands on the Storck Aernario Disc for a proper demo ride. I spent 4 hours on this German steed last Saturday and came away very impressed. Germans are known for outstanding engineering. Just take a look at brands like Porsche, Bosch or Siemens. Storck is no different. These bikes carry a very high level of engineering yet Marckus Storck injects an impressive amount of art and personality into the bike. First and foremost, road discs are the real deal. The power and modulation available completely changes the game. You can wait longer to brake into corners and you can brake harder without fear of skidding. The Aernario takes complete advantage of the brakes' qualities and brakes and corners like a race car. Second, the bike is stiff. This is an excellent race bike or perfect bike for the hard charging enthusiast. Every pedal stroke is answered with noticeable forward motion. Nothing is lost when hammering out of the saddle. How about ride quality? Well, I spent 4 hours on bumpy roads. I wouldn't say its a comfort bike by any means but the ride quality was excellent considering its stiff, racy nature. I also have a teammate who has podium'd twice in the 206 mile LOTOJA Classic on the Aernario. Proof that fast doesn't have to be harsh. Anyone looking for a race and performance oriented bike that walks the talk, put the Aenario on your list. Hit me up with any specific questions! btowery@backcountry.com


I hav 1 n what utter fantastic bike! Di2 9070, Enve cockpit with Enve XC ceramic bearing tubular wheels. XTR brake pistons. Hit 60 mph on a 25 mile down hill n the whole rig was solid. Had 23 vittoria tires n switching to 25 vittoria. Love that giant BB. bolt-thru front/rear axels keep everything Rock solid. Crazy awesome bike!

Smooth and Stiff.

I've used it several times

This bike is exceptional. I rode the soon to be live featured bike, including DuraAce 9070 Hydraulic disc, IndustryNine/Reynolds Aero58 wheels this morning and it was a stunning ride. Smooth and stiff on the climb, super comfortable ride without sacrificing stiffness. A real contender on the descents, the disc brakes really increase confidence of this already stable, fast frame. A fantastic ride.
