Calfee Sizer Cycle; Fresh Batch Ready to Ship


Craig Calfee started building carbon frames in 1987, when “plastic bikes” weren’t very popular. Greg LeMond discovered Calfee’s bikes in 1991 and that meeting introduced Craig into the world of fussy professional racers. Being a custom frame specialist, Calfee became familiar with the limitations of sizing programs and adjustable fitting bikes. Framebuilder Bernie Mikkelsen had been working on a better sizer for many years when Calfee proposed to help bring it into production. A deal was struck and now there is a steel fabrication corner in Calfee’s carbon fiber frame shop. That is where the Calfee Sizer is produced.

Now it’s easy to obtain the exact geometry needed for a custom frame.  This sizing cycle is made for ease of use and ease of understanding by the person being fitted. The technician can quickly and easily adjust all the important dimensions with quick releases and a hand crank top tube extender. The top tube extender is especially handy for the rider to feel the effect of a longer or shorter top tube while the technician turns the crank handle.
