About Us

Broken Carbon is the premier carbon fiber repair shop. Backed by multiple undergraduate and graduate degrees in engineering plus a 30+ years of racing experience, nobody understands composites and the requirements of high-end bicycles like we do.

Founder - Brady Kappius

I started experimenting with composites in high school with my Dad. As lifelong cyclists, we saw the increased use of composites in the cycling industry in the early 2000's and wanted to learn more. I followed my dad's footsteps and attended the Colorado School of Mines while still focusing on my cycling career. After turning professional, I attended the University of Colorado to pursue my masters and founded Broken Carbon at that time. I had a few people come to me looking for repairs and through word of mouth, Broken Carbon has just grown from there!

Engineer - Cameron Frazer

With my Masters Degree in Composite Engineering I assure all repairs performed here at Broken Carbon are of high quality. Designing a repair from a structural point of view is not trivial, and no repair is identical. Different types of repairs require not only different types of 'layups', but they also require different methods of manufacture to replicate the original laminate.
