You really don't ride a smaller frame in tri geometry than road. Some companies make more of a "compact" frame for the tri market, usually driven by a short head tube. In reality, it's going to be determined by finding your best position, then finding the frame that will allow you to achieve this position and maintain balance and stability. Find a shop in your area that caters to the tri market, and let them help you.

a 'triathlon' frame simply utilizes a steeper seattube angle and shorter headtube....you cant generically 'downsize' a roadframe size to a triframe.

just like a roadbike, tribike fitting is highly individualized. If youre not sure where to even begin, consider a professional fit (cant believe i just said that).

Do you have a roadbike? save some money and tweak your fit. Get a zero-setback or forward seatpost. Get some short aerobars. Not only will you save some money, over time you'll get a better idea as to what type of trifit youd like.
