Security and innovation. These two words best sum up our A6 Carbon Technology Platform (CTP™). The result of more than a decade of carbon bonding experience, the CTP Surface System maximizes bond strength and durability by sophisticated joint interface technology and superior bonding surface area. Textured "standoffs" molded directly into each part ensure ideal glue gap for 100% epoxy strength, while precision-machined interface surfaces create the most exacting fit-up possible. What's more, Seven's patent-pending joint interface technology not only enables us to fully customize frame geometry, but also provides added joint integrity. And like all Sevens, our A6 carbon frames are built to order, 100% in-house, which ensures just-in-time materials prep and machining, maximizing cleanliness and attention to detail.
A great bike isn't so much a matter of what it's made of as how it's made.
Though myths still persist, simply knowing that a bicycle frame is titanium, carbon fiber, or steel will not tell you how it will perform. For each material, there are great bikes and not so great bikes.
At Seven, frame building demands a thorough understanding of each material's properties and strengths and leveraging them through innovative design engineering. Combine this approach with the absolute highest-quality materials and benchmark craftsmanship, and you have the makings of a truly great bike.
Whether titanium, carbon, or steel, Seven frames benefit from the most sophisticated materials technology available. Our approach to developing our tubing relies on carefully leveraging a material's strengths, while mitigating less desirable traits.
Consider our proprietary titanium tube butting technologies, which allow us to hold wall thickness variations to within 0.001"-less than the thickness of a human hair. While this might sound extreme, a deviation even this small can create a 5% difference in a tube's ride characteristics. Tolerances this tight are critical to controlling elements such as weight, stiffness, compliance, and durability. And unlike swaging, tapering, and internal butting, our technologies do not degrade titanium's grain structure, and thus provide superior fatigue life for a given weight.
Two-years in the development, Seven's patent-pending carbon frame design and construction technology is truly groundbreaking. The design optimizes carbon's formability to produce the most innovative carbon frames available. Fully customizable, aerodynamic, and lightweight, no other carbon frame offers as much.
Breakthrough design requires stepping back and carefully examining one's assumptions. As such, product development at Seven takes nothing for granted. From the first frame to strategically pair carbon and titanium tubes, to the most customizable lugless carbon frames, looking at things differently has yielded a long list of industry firsts for Seven over the past decade. But more important, it's yielded a lot of very happy cyclists.
