Why Our Frames Kick Butt…Part 1

Dragonfly Pro

Advanced Materials:

Calfee frames are designed with carbon fiber composite.  This is a highly-advanced woven material impregnated with a thermosetting epoxy that was first used in the aerospace and boating industries because of it superior stiffness-to-weight and strength-to-weight ratios.  Composite’s vibration dampening is also far superior to any metal, creating an exceptionally smooth ride.  Taking it one step further, we’ve introduced the bicycle world to boron/carbon fiber composite tubing, which creates an overall stiffness even greater than that of the individual fibers.  We use titanium fittings wherever possible because they resist rust and corrosion, and they don’t naturally separate from the carbon because of their nearly identical rate of thermal expansion.  If aluminum fittings must be used, we insulate them from the carbon with fiberglass.
