It’s that simple.

We want carbon fiber to be more accessible and affordable for everyone. This means creating unbelievable products, and even better experiences. We do that by building the best, most energetic, and collaborative team, and by making a meaningful impact in everyone’s daily life.

Common Fibers Promo is part of Composite Fundamentals INC. Proudly based in Seattle, WA.


We believe to be accessible, it has to be easy.
Easy to work with, easy to associate with, and most importantly, easy to find.

Collaboration makes things easy. Our team, and our product, is easy to work with. Amazing brands are easy to associate with. Distribution makes it easy to find.
