Is This 3D-Printed, First-of-Its-Kind Bike Frame the Future of Cycling?

Meet the No. 22 Reactor Aero, the world’s first 3D-printed titanium road bike, now taking pre-orders.

When I first laid eyes on No. 22 Bicycle Company’s new Reactor Aero prototype, unveiled at Portland’s MADE bike show late last month, I was at first stunned and then skeptical. Initial reaction: “Holy shit, a super-aero 3D-printed titanium roadie, that’s insane.” Secondary reaction: “Eh, this is just a concept, it’ll never be real.” 

No. 22 put the new frame through numerous computational fluid dynamics simulations, achieving a whopping 30–40% drag reduction versus its predecessor. The development process also focused on drivetrain stiffness, which should make for hyper-efficient pedaling. 

Thankfully, in a stunning development, I was dead wrong. Not only is the Reactor Aero very real, it’s coming at us fast. The brand has begun accepting pre-orders today, with a current lead time of 12 weeks. Here’s what you need to know.

Breaking the mold

Founded 13 years ago and now operating out of an old knitting mill in upstate New York (Johnstown, specifically), No. 22 has not wasted any time establishing a rep for excellent handmade titanium bikes. (The company is named, after all, for the atomic number of titanium.)

At the vaunted North American Handmade Bicycle Show in 2019, the brand was a finalist in three categories and won three others, including Best in Show, cementing its place as a truly top-notch boutique bike maker.

Among No. 22’s current nine-bike lineup, the Reactor has always been the most race-ready, so it’s no surprise No. 22 chose to innovate this particular frame into an aero-optimized titanium speed freak.

They put this new iteration through numerous computational fluid dynamics simulations, achieving a whopping 30–40% drag reduction versus its predecessor.

The development process also focused on drivetrain stiffness, which should lead to hyper-efficient pedaling.

The new Reactor is fully 3D printed, monolithically, from Grade 5 titanium powder, except for the aerodynamic carbon integrated seat post, created in collaboration with July Bicycles.

So, why 3D printed titanium? “[It] has phenomenal structural properties,” says No. 22 co-founder Bryce Gracey. “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 can 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.”

I don’t think I’ve never been so glad to be so wrong.

The finer points

Along with that unprecedented frame construction process, the new Reactor carries many modern touches, highlighted by the following.

  • Fully internal cable routing
  • Flat mount disc brakes
  • Clearance for measured 34mm road tires
  • 100×12 front thru-axle, 142×12 rear thru-axle 
  • Aero integrated carbon seat mast c/w 3D sintered titanium seat mast topper
  • Internal routing c/w titanium headset and stem. 

Availability and pricing

The No. 22 Reactor Aero is available for pre-order now, with delivery expected sometime next year. Of course, this level of craft and innovation does not come cheap. The required $1,000 deposit will be credited toward the final purchase price of the frameset, estimated between $10,000 and $15,000.

Note: Deposits are non-refundable but can be transferred toward the purchase of another No. 22 bike if the customer decides to shift gears, so to speak.
