Joining the ranks of many other new aero road bikes racing in with disc brakes, Storck just unveiled the newest Aerfast. The Aerfast 3 builds on their aero road platform in a way that makes it more impressive than just adding disc brakes. According to the company, the new bike is more aero, stiffer, lighter, and even more comfortable.

One of the biggest changes to the bike is the move to a fully integrated cable system which hides almost everything from the wind. Each bike ships with their RBSU Aerfast3 carbon stem/handlebar which mates to matching aero spacers which hide the cables as they enter the headtube.

After spending some time in the wind tunnel, Storck was able to tweak the tube profiles to gain a bit of free speed. Claiming that the new bike requires 11 fewer watts to maintain 45 km/h, that’s not a huge increase – but they did it while adding stiffness, reducing weight, and adding compliance.

Power transmission is said to be 10% better, while headset stiffness has been increased by 13%, and lateral stiffness at the fork increased by 14%. Thanks to a new, more compliant seatpost, comfort is said to be 13% better as well.

And even after adding disc brakes, the bike checks in at a claimed 7.5kg (unspecified complete model without noted sizing).

Offered in two complete build levels, the gold accented Pro starts at 5,698€ while the black on black Comp model starts at 3,499€ (or 4,499 € with the DT Swiss ARC 1100 Dicut wheels as shown above). There is also a frameset offered with the frame, fork, seatpost, and headset for 2,699€.

Bikes will begin delivering by the end of December, with preorders available now.

  1. Lord, the confluence in the aero bike market is strong. Literally every design cue on this bike have been offered by at least 4 other MFGs over the past few months. Getting increasingly hard to differentiate themselves.

  2. How can you simultaneously increase stiffness AND increase compliance? This marketing speak really makes me scratch my head sometimes.

    • Because the stiffness increase could be lateral or torsional while compliance that is aimed for is generally vertical. Extremely difficult to do with metal tubes but carbon can be laid up to provide properties in the desired directions, to a certain extent ayway. The improvements though are often “marginal” shall we say. Ie. 10% more compared to what? 1mm deflection? So a 0.1mm improvement. Good luck noticing that. I’m not saying those numbers are what this brand are claiming but without the percentages being quoted alongside meaningful numbers it’s nothing more than marketing speak.

    • Because it’s marketing BS. Those percentages are misleading. 10% stiffer is code for “10% reduced deflection”, but that’s not how that works and they don’t give you any numbers. Heck, they don’t even say if these are measured or theoretical values. If the previously measured deflection was 5mm, then 10% less would be 4.5mm. No way you’d notice the difference, but you don’t even know if that’s the case.
