I'm in the market for a road bike. Given my limited funds, I'll
probably buy something off ebay. To keep from being overwhelmed with
too many options, I've limited my bargain-hunting so far to Treks,
which has led to the surprising discovery that Trek makes:

1. traditional road bikes (eg. (the 1000, 1500, etc.) marked by a
level/horizontal top tube, among other things, and

2. "comfort" road bikes (eg. Pilot 1.0, 1.2, etc.) with a supposedly
"more natural riding position," marked by a top tube sloped up from
seat post to headset, thus raising the handlebars relative to the seat
position.

I really don't understand the practical difference in terms of riding
position b/n the two. Doesn't matter if the headset is higher than the
seat post and what angle the top tube is at, with the way how people
typically fit it, the seat is invariably significantly higher than the
handle bar. The top tube angle is almost irrelevant as it's the handle
bar level and seat height that determines that so called "comfort"
position.

There may be handling, ride quality differences b/n the two, but I just
can't see what comfort has to do with it.

Of course, this is assuming identical seat and fork angles and other
basic geometries.
