The Kilo TT is a very nice bike ...

Based on your measurements and the frame size chart I would go with a 53 or 55 cm:
Sizing: (c-c = center to center seat tube, c-t = center to top, TT = top tube c-c)- 44cm (c-c) is 47cm(c-t) with TT of 503mm* and standover of 28.5 inches
- 47cm (c-c) is 50cm(c-t) with TT of 513mm and standover of 29 inches
- 50cm (c-c) is 53cm(c-t) with TT of 523mm and standover of 30.4 inches
