from searching, i've gathered that the poprad's sizing is generaly large. however, there seem to be varying opinions. what i'm wondering is, for you poprad owners out there, what size do you ride relative to your other bikes, past/present. i ride a 55 track bike, and a 54 cannondale caad 9, but i would ride a 56 road bike by trek's normal sizing. anyone out there in my range with experience?
