Broken Carbon

Engineer and pro bike racer Brady Kappius has been making and repairing composite parts for five years, and has become a fixture in the lively Boulder, Colorado, cycling scene for his frame-saving skills. Broken Carbon is a new venture, and offers repairs of a worn area for as little as $100, or repair of a completely separated tube starting at $225. Rush delivery is available, with a turnaround time of only 24 hours in most cases, for a 75 percent surcharge.

Broken Carbon will do small, single-color paint touchups and clearcoat work, but isn’t a paint shop. If you want a perfectly matching paint job or decals, it’s best to take the repaired frame to an expert finisher.

Kappius is happy to fabricate components for customers, too. Quite a few dirt-oriented Boulder pros are riding around with his custom carbon downtube protectors, which add impact protection with minimal weight.

Response to the frame:
Responding to emails while in Malaysia for the Langkawi International Mountain Bike Challenge, Kappius quoted us $175 to repair our broken top tube, with a turnaround time of 1-2 weeks.
