can this be a sticky already?

and like scrod said standover height isn't the only thing you should put into consideration when choosing what bike you ride but if you really want a kilo (I got one too) then look at this chart and then buy one and cross your fingers. Or you can find people locally who have kilos and try them out.

From BikesDirect:

NOTE: Sized center to center, most riders fit a size smaller than they fit in a center to top sized bike
Example - if you ride a 58cm center to top sized bike then you may prefer the 55cm Kilo TT
Please refer to the sizing charts before making your own purchase decision

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
53cm (c-c) is 56cm(c-t) with TT of 548mm and standover of 31.5 inches
55cm (c-c) is 58cm(c-t) with TT of 560mm and standover of 32 inches
57cm (c-c) is 60cm(c-t) with TT of 575mm and standover of 33 inches
60cm (c-c) is 63cm(c-t) with TT of 606mm and standover of 34 inches
63cm (c-c) is 66cm(c-t) with TT of 630mm and standover of 35.5 inches
(*estimated measurements of new size)

Most riders fit the size they clear the standover by 1-1.5 inches
The "standover" is the distance from the floor to the upper surface of the top tube that is between ones legs when straddling the bicycle. Most riders want at least 1 to 1.5 inches between them and the hard chromoly steel top tube.

If you are between sizes, keep in mind the smaller one will have lower handlebars and more agile handling. The larger one will have higher handlebars but less straddle room. Your personal preferences will determine your size.
Another tip is to choose the bicycle that has a top tube length closest to the length of what you currently prefer.
The final choice is up to you.
