LBS know nothing, or they're too blinded by compact frames to know any better. 32" inseam here, and many of my machines hit the 31" mark, if not the 32". I never feel it nor hurt myself on 'em. The slightest angling of the frame when dismounting takes care of that.

That said though, the 2010 RRA is a compact frame. A 58/59cm ST example will likely have a much longer top tube than you expect. Compact frame sizing is completely different from traditional. Size your frame based on your preferable effective top tube length; not the seattube length.

P.S.: I saw you riding the 23" (ST) Armstrong a few days ago. The fit looked fine. Don't change the winning combo.

P.P.S.: You wouldn't happen to have spoken to an arrogant little, glasses-wearing, hipster clod at Bike Tech on Bird Rd., eh? I generally get along with everyone else, but I flatly refuse to deal with that jerk. I have no trouble admitting that to his face either - that's how much of a creep he is.
