U.S. Built Custom Bicycles in Titanium and Titanium-Carbon Mix
Materials matter. And how you handle them matters, too. At Seven we start with the best raw materials available to us, and then, through a deep understanding of the underlying metallurgy, we refine them to produce the best bike for the person who will ride it.
To begin with, we reject the idea that one material is best for every rider. At Seven, we take a rider-specific approach to materials. For some we recommend titanium, and for some we suggest incorporate carbon fiber into the frame.
Titanium and carbon fiber have different characteristics that speak to an array of design priorities. Carbon fiber can be light and stiff. Titanium can be durable and tuneably for a range of ride characteristics. All of these are positive and, in hands of an experienced builder, can form the basis for a great bike.

Interestingly, while riders have believed for years that the type of steel a frame is made from is supremely important (we agree), they have simultaneously assumed that titanium is just titanium, that it's all the same.
Nothing could be further from the truth.
Seven sources Cold Worked – Stress Relieved (CWSR) titanium four our frames. We do that because no other titanium available today has a longer fatigue life or higher tensile strength. We know that's true because we have a fatigue tester here in our shop and regularly submit tubes to rigorous testing. Pushing materials to their breaking point is a great way of finding out how good they are, and our research indicates that the titanium we source is the strongest available and maintains that strength over significantly longer periods.
We always want to use the best materials, because we want to build the best bikes, but we also have a commitment to lifetime warranties that prevents us from cutting corners with lower quality products. When you buy a custom Seven, you put your faith in us to produce a bike that will fit like a glove, corner on rails and last forever. Seven's CWSR titanium allows us to repay your faith with a frame of uncompromising quality.

Specifically engineered for light weight, our unique multibutting process varies the wall thickness continuously along the tube, shaving weight wherever possible for our lightest tubeset ever.
The cornerstone of our materials offerings, Seven's SL tubesets provide the perfect balance of lightweight, responsiveness, and durability.
A high-performance straight-gauge tubeset for ultra-durability and greater affordability.
Of course, it is also possible to mix materials to take advantage of an even wider range of benefits, as in our titanium-carbon mix frames.
When we think of the inherent qualities of titanium, we think about compliance, the ability of the material to flex and return to its initial position, strength, durability and customizability. Titanium is light and strong, lasts forever, and can be tuned through astute tube manipulation to produce very specific ride qualities.
Carbon fiber is, in most instances, even lighter than titanium and adds the value of excellent vibration dampening, so that when we mix it with titanium, we get extremely light frames that produce a butter smooth ride.
In order to get to the optimal frame performance, we are strategic about where we use each material. We use titanium at the joints, where strength and compliance are most important, and we use carbon in the main tube sections, where weight can be sacrificed and road vibration can best be dissipated.
