No. 22 Launches Reactor Aero: The World’s First 3D-Printed Titanium Aero Bike

Innovation is paramount in the world of cycling, and New York-based company No. 22 is setting new standards with the Reactor Aero, the world’s first 3D-printed titanium aero bike. The model combines state-of-the-art technology with exceptional design and promises an incomparable riding experience. The Reactor Aero is based on the existing Reactor racing bike model, but has been further developed as an aerodynamically optimized racing machine. This was done in collaboration with external engineers and aerodynamicists.

No. 22, known for producing handmade titanium bikes, has developed the Reactor Aero, a prototype made almost entirely of titanium. This is a remarkable step forward, as usually only titanium eyelets or carbon fiber frames are used. The high-performance road bike was also exhibited at the MADE bike show in Portland from August 23-25.

The titanium racing bike not only impresses with its aerodynamics, but also relies on in-house production methods and innovative 3D printing technologies for frame production. Grade five titanium powder was used for this. The exception is the seat post, which is made from carbon fiber.

Bryce Gracey, co-founder of No.22, explains: “3D printed titanium has phenomenal structural properties. The ability to print internal support structures anywhere in the frame gives us a level of control over the ride quality that has not been possible before. We are able to add stiffness in high load areas like the bottom bracket, dropouts, and head tube for very little weight while playing with structure in fine detail throughout the frame to ensure it delivers the ride quality we need”

The Reactor Aero also underwent CFD simulations, a computer-aided analysis that examines the airflow around the bike and the rider in order to optimize air resistance and aerodynamics. Initial tests show a reduction in air resistance of 30 to 40 % compared to current models. During the development phase, the performance of various areas of the bike was improved, including the stiffness of the drive unit.

To this end, the down tube, bottom bracket junction and chain stays were redesigned to take advantage of the freedom offered by 3D printing. Other tube profiles and crossings were also redesigned from scratch to combine stiffness with ride quality.
