U.S. Built Custom Bicycles in Titanium and Titanium-Carbon Mix

The 622 XX

Seven's 622 XX road bike, carbon with titanium lugs

We had been thinking about the 622 XX for 14 years before we built the first one. In 1998, it just didn’t seem possible. There wasn’t the breadth of carbon tubing we have today, and the design was maybe too far over the edge from what we were already doing at the time. We wondered if the market was ready.

We put away our sketches.

We came back to them in 2005. Carbon fiber had come a long way, and we were thinking about how we could incorporate the material of the moment into a great, custom bike. Instead of building the 622 XX then, we poured our energy into designing a custom carbon platform, a whole new way of building bikes, from the ground up, and we built those bikes for seven years before returning to our original design idea.

The key to the whole project is the lugs. Lug work has a long heritage. There was a time, when all bike builders were still working exclusively in steel, that the quality of a builder’s lugs was the measure of their skill. A lug had to be beautiful, but it also had to serve its purpose. Form had to follow function.

The titanium lugs in the 622 XX are as thin as they can be while maintaining durability and compliance. They take the edge off the frame’s carbon tubes, which on their own provide more than ample stiffness. We added some aesthetic flourishes, too. A tapered 7 at the head and seat tubes, geometric cut outs at the other junctions. When people first see the bike, these are the things they notice.

The carbon tubing in the bike comes from a partner in Utah and is filament-wound to our exclusive specification. Each layer of material has been chosen to produce very specific ride characteristics. Filament-wound carbon, as opposed to its roll-wrapped equivalent, provides a consistent, accurate quality.

The name for the bike comes from the Periodic Table. 6 is carbon. 22 is titanium. And, by merging them into one number, we are expressing exactly what we want the bike to be, a true union of the materials, a whole that is greater than the sum of its parts.

The 622 XX is either a carbon bike that doesn’t feel plasticky, or it’s a Ti bike that is lighter and stiffer than any that came before it. Or maybe it’s a new bike, a bike that makes use of the best materials, that borrows something from the heritage of bike building but leverages the technology of the moment to produce a ride that is at once light, stiff and comfortable.

The Axiom

If you fly over New England in an airplane, it looks like a patchwork of farm, forest and town, irregular and haphazard. Our roads are very much the same way. Stretches of smooth pavement are rare. Potholes, patches and gravelly shoulders more or less define the riding here. So when we’re designing a road bike, we often start there, at the road surface, and we think about what kind of a bike will work best.

An Axiom is a starting point, an idea that leads to other ideas.

Myth vs. Material

At Seven, we adhere tightly to the philosophy that form follows function. That’s why when designing a bike, we start with its mission and work back to the frame material selection.

We believe there are no bad materials, just bad applications.

We recommend the same approach when choosing your bike. Instead of first deciding upon a frame material, consider, “What do I want from my bike? How do I ride?” Crit racing, charity rides, touring, fast club rides, randos, solo rides, mixed surface explorations, all of the above? The answer can help lead you to the right material—and it may surprise you.

The Five Elements of Customization

We are, all of us, trying to get back to that moment, when we were two, or five, or ten-years-old, of first pushing off and feeling the freedom, the joy of riding a bike. The 5 Elements are meant to get us there, to strip away the fear and focus on the idea for a new bike.

First, The Idea

There is no bicycle without the idea of a bicycle,

without the inspiration to go somewhere. This part of the process, the beginning, is crucial. Fix the idea in your head. Keep your eyes on the destination.

The best bikes are made of these things.

Before a frame drawing gets made.

Before a tube gets cut.

Before the welding torch burns brightly.

The kernel of the idea is in what the bike needs to do, where it wants to take you next.

The whole bike is contained in the path it will travel, all the details falling out of the necessities of the ride.

Will it be fast? Will it be comfortable? Will it have wheels like this and handlebars like that?

What is your idea? And when can we build it?
