Craig Calfee is an innovative bike builder and the founder of Calfee Design. Calfee was an early adopter of carbon fiber for bike frames in 1987, and brand's ​​Tetra road bike is said to have been in production longer than any other carbon bike. You might also recognize his work with Bamboo bike frames, which he began in 1995. How did you get your start building bikes? What did people think about the carbon bike frame you debuted at Interbike in 1989? Were there concerns that carbon frames were untested? Are you still doing carbon frame production in the US? How does carbon frame repair work? Your mountain bike, the Cephal, utilizes a system called Quick Tune Steering. What's the idea behind this feature? The Cephal is a hardtail with "leaf spring chain stays."  What are the benefits to having flexible chain stays? Were you surprised about your bamboo bike frame prototype? From a practical standpoint, is bamboo a good material for building bike frames? Why do you offer so many different tandem bikes? What are the challenges associated with building a tandem, particularly a mountain tandem?  How does your electric pedal assist retrofit service work? What kind of work have you done on adaptive bikes?  What's next on the horizon for Calfee Design? Connect with Calfee Design and learn more at calfeedesign.com.
