I read somewhere recently, can’t remember if it was here, about someone who was going to take his fit specs for a tri bike and make a few adjustments to determine his road bike fit specs. Would this produce a satisfactory set of road fit specs, and, if so, how do you go about it? I don’t have the $$$ to pay for a separate road bike fit right now but I’d like to be able to snap up a deal on a good used road bike if I find one.
Despite the remarks a week or so ago on how uncool this is…

Hoping some of the bigger bike geeks are surfing the web now. Thanks for any insights.
Take a picture of yourself on the TRI-bike, use a photo-editor to mark the joints & draw the lines between them - then rotate everything (around the bottom pedal axis) from 78 (or whatever angle you’re at) to 73… 
Take a look and/or/save/print this article from the Park Tool website on documenting road bike position (works for tri bikes also): http://www.parktool.com/repair_help/roadposition.shtml
With the Tri bike measurements in hand, you can then transfer them to a regular road bike making allowances for such things as saddle setback and bar position by using the tri positon numbers as a baseline on which to start. Use the road positioning chart (http://www.parktool.com/pdf/positionroad.pdf) for each time you make a change - I suggest annotating the change to a new sheet so that you ahve a record of changes - until you get it were you want which also allows you to easily regress to a previous point should you start making changes that you do not like.
