I'm 5'6" I typically ride a 52cm road frame.

Test rode a Big Dummy in "Small" (16 in.) yesterday. It felt kind of, well, small. The shop insists that it's my size, and Surly's quick reference size chart would agree. But I still think it felt small.

I think maybe the shop is insisting it's my size because it's what they have in stock. Or maybe it's just that I'm used to a more stretched out position on road bikes.

Thoughts?
