Nice bikes. I am new to road bikes, still researching for the first. Are most of these bought as a frame and parts are added as the rider preference or are they be bought "off the floor"? I guess that is a general statement for most tri-bikes and riders.
If you are buying a bike brand new, by a long way the cheapest option is to buy a complete bike, that is, frame, group set (gears, brakes etc that make the frame go somewhere) and wheels.
The wheels won't be race wheels, but usually good quality training wheels.
There are two options:
1) A road bike, which you can add clip on aero bars to.
2) A time trial bike.
For example, the poster above with the two cervelos. The road bike is the white one, and the other bike is a dedicated time trial bike.
There are some good articles on slowtwitch main site about choosing a bike.
Once you get the initial complete bike, the next thing most people purchase is a pair of race wheels, that are usually lighter but most importantly more aero-dynamic then training wheels.
