One of the pioneers of carbon fiber framebuilding, Craig Calfee got his start in 1987. He invented three different ways of making carbon fiber frames and was the very first to offer them in custom geometry.

Craftsmanship. That’s the word that comes to mind first when people talk about Calfee. Every frame goes through hours and hours of precise measurement, workmanship and finishing. More than 51 million fibers are carefully oriented to put strength and stiffness exactly where you need it. The result is a frame that lives up to your very high expectations as well as its unusually long warranty.

Comfort, fit and real-world conditions are important considerations integral in every frame we build. So, we ask ourselves a lot of questions. How well with the frame withstand high altitude and low temperature in the cargo bay of a plane? How will a cyclist’s hands and shoulders feel on the 20’th lap of a criterium or mile 80 of a century? What’s the optimal frame stiffness for a 6’6”, 250 pound randonneur or a 5’10”, 155 pound ironman?

We also know that if a bike doesn’t fit well, a cyclist can’t ride well. That’s why our frames come in eleven standard sizes. For 80% of our customers, those measurements are a perfect fit. And for the rest, we are happy to build a totally custom frame.

If you would like to explore custom frame geometry, you may choose to consult a convenient shop or studio, publish key measurements from an existing frame, or visit us in Santa Cruz County for a complimentary fitting and factory tour.
