R1c Frame

Light, stiff, and comfortable; we designed it that way. It is now a cliche to state "we took advantage of the unique properties of carbon fiber to... ".
The fact is we have been designing and building with carbon for over 20 years, and we are quite good at it. When we decided to make a frame, we wanted something that would measure up to the wheels we've been making for years.
The R1c has a stout head tube, large diameter down tube, and built up bottom bracket that make the frame rigid and efficient for sprints and out of the saddle climbs. Hooked chainstays both lighten and stiffen the rear wheel dropouts when compared to more traditional construction.
To make the frame comfortable without compromising stiffness we employ tubes with variable shape and diameter. The tubing diameters are largest at the headtube and seat tube junctions for stiffness and tapered in the middle sections for comfort.
Careful material selection and exacting layup keep the frame weight low and give us the blend of comfort and stiffness that we wanted on the completed frame.
