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.

Winning at NAHBS 2019

There were so many beautifully made bikes at NAHBS from builders of all sizes, that we were honored and humbled to walk away with the awards for Best Road Bike and Best Gravel Bike as well as being named a finalist for Best Mountain Bike.

Why did our bikes win?

For the judges, it seemed, everything came down to technology. Among the carefully made bikes at the show, the lion’s share of the titanium models were straight gauge bikes with off-the-shelf dropouts. Most had stunning paint jobs. They all looked great, but as bikes, they weren’t necessarily difficult to execute and didn’t always express an ability to customize deeply.

Our winning road bike, the Ultimate Axiom Disc, improved on the simpler builds at the show in three key ways. First, the level of tube butting was beyond many other builder’s capabilities. We butt our own tubing, in-house, based on rider profile and customize down to one-thousandth of an inch.

For the show bike, we also butted the custom Ti seatpost, chainstays and seatstays. Our XX upgrade package also modifies the standard tubeset in about a dozen ways that other builders aren’t yet able to replicate. The mix of one-inch chainstays and Moto seat stays comprise the sort of purpose-built modifications that go beyond looks, deep into technological improvements that make the bike faster, make it handle better, and improve its traction.

Finally, the bike is finished beautifully using a method, MCT (or Multimedia Color Technique), developed in-house at Seven. MCT is a layered finish system that uses bead-blasting, dry stenciling, other materials and methods, clear coat and matte finish, as well as regular wet paint and other surface effects, depending on the design.

For the gravel category we built a one-of-a-kind Evergreen PRO SL, another bike that showcased our ability to design and execute a bike deeply refined for its purpose. For this bike, a fast-riding, packed-dirt rider, we incorporated a one-inch Chopped chainstay into a classic Seven Ti/carbon frame. The blend of materials, which produces stiffness in all the right places and compliance everywhere else, is perfect for going fast off-road.

The Chopped chainstay, which had show-goers gasping for three straight days, shortens the rear of the bike, which boosts traction, acceleration, and agility. We finished that bike with another eclectic MCT design with matching wheels, headset and hubs.

Our takeaway from NAHBS is that technology matters. Show bikes need to look great, but there has to be more beneath the surface. The judges responded to our work in exactly the way we hoped they would, but riders also recognized what was going on with each bike and appreciated it.

The good news for you, our riders, is that Seven doesn’t really build show bikes. Every bike we had at NAHBS can be ordered by any rider at any time and delivered on our standard timelines.

Seven Design Philosophy – Understanding Chainstays

Seven Cycles offers a variety of chainstay styles, each with their own unique features and benefits. Our most popular designs include our Inline stays and Chopped stays.

The popular perception is that chainstay length is one of the most important factors in bike design because stay length affects bike handling, acceleration, climbing ability, and descending stability. While it’s true that chainstay length has an important impact on all those aspects of a bike’s character, stay length is only one factor in more than 200 design parameters that go into developing an ideal bike.

Anytime we put too much emphasis on one design element at the sacrifice of others, the result is a sub-optimal riding experience.
