The initial production launch of Reactor Aero models will be built in our standard stock size range of 48cm to 60cm sizes, in even-cm increments. We do expect to be able to offer custom sizing in the future, but we anticipate that custom sizes will not be available at the bike's production launch.

ESTIMATED FRAMESET PRICE AT PRODUCTION LAUNCH: $10,000-$15,000
First customer deliveries anticipated late 2025
The Reactor has always been the most race-oriented road frame in the No. 22 lineup, and the Reactor Aero is the world’s first truly aero-optimized titanium race machine. Developed in-house and subject to multiple CFD simulations, the Reactor Aero is scheduled for wind tunnel testing and validation before launch. Testing to date confirms 30-40% drag reduction when compared to the current Reactor. As with all of our models, every piece of the frameset is either made by or specifically for the brand, providing an unrivaled level of control and precision in the manufacturing process.
In developing the Reactor Aero, we are aiming not only to set the bar for titanium frame aerodynamics but to enhance performance in all other areas as well. Drivetrain stiffness, which the Reactor is known for, has been further improved upon resulting in likely the most efficient power transfers available on a Ti frame. To achieve this, the down tube, bottom bracket intersection, and chain stays were fully redesigned and optimized by utilizing the formal freedoms offered by 3D printing. All other tubing profiles and intersections were also built from the ground up to help temper drivetrain stiffness with the legendary ride quality titanium is known for.
The current prototype as shown is a fully 3D printed frame, printed monolithically from Grade 5 titanium powder, save for the seat tube. In keeping with the previous generation of the Reactor, the seat tube is a carbon ISP, this time with an aerodynamic profile, co-developed and produced by July Bicycles. The final version will be printed as sections that can be machined and welded in-house, allowing us to leverage our titanium fabrication expertise resulting in tighter controls over quality, tolerances, and finishes.
