Hi Kurt,

I thought that you would want a rigid frame for a TT bike and it surprises me that this supposed MASI frame has curved seat tube and top tube.

I thought curved tubes would reduce rigidity with more metal stress and fatigue and not allow for as quick a start as straight tubing. I wonder if this frame was made of straight gauge tubing and not DB to allow this curving

Can one of the CR frame builders explain why this MASI frame may have been constructed this way other than for visual impact?
