I tape measured the center-to-center on the seat tube at about 40 1/2 cm. This is really close to the 42 cm shown for the 50 cm Ligero. The bike did use standard 700c wheels. I figure that if the frame were a 48 cm, Titus probably would have switched to a 650c wheel.
The previous rider was about 5' 4 and roughly 125 pounds. Sorry about the earlier listing mistake. See my feedback for how I do business.
