MEASUREMENTS: Frame measures 21-inches from center of BB to top of seat-tube, which is commonly called simply a MEDIUM frame (also, since 21 inches equals roughly 53.5cm, you could accurately call this bike either a 53cm or a 54cm). Top-tube measures about 21.5 inches from center-2-center. Standover is just over 30.5 inches with the current 38c tires mounted.
PRICE/SHIPPING: But It Now price is $549. Shipping to anywhere in Lower 48 United States is $149 (sorry, NO shipping to Alaska or Hawaii; also, NO shipping to PO Boxes) — but if you live near the Seattle Metro area, you can instead pick up for FREE at my home in the Redmond WA area, which is about a half hour drive due east of downtown Seattle.
