how come on some bikes the top tube slopes, while on others its flat? What are the advantages and disadvantes?

And does anyone have a link to a good site about learning to ride road bikes properly for beginers.

It is thought by having the top tube slope you can achieve these advantages (amongst others possibly):
1) less materiel = less weight of frame
2) stiffer frame
3) fewer sizes manufactured controls cost
the disadvantages:
1) much higher seatpost will increase weight, maybe not to that of "normal" top tube frame
2) long seatposts flex\
3) many people dont fit them well

Bottom line, if it fits well, go for it...if not, dont.

Sloping top tubes are called "Compact Frame" or "Compact Geometry". For road bikes it's a newer design than a straight top tube, called "Traditional Frame/Geometry". Some people swear by Compact frames and the Spanish ONCE team has standardized on them. Others prefer traditional geometry. Here's a thread about the differences. Scroll down to "legs" post for some good pros of Compact frames. But as you can see, it's a mainly matter of personal preference.

As for learning to ride, I'm a noob too and have learned a ton just from this forum over the past few months. If you have a question about something, search the forum b/c it's probably already been asked or answered. If not, just ask and there are plenty of knowledgeable and helpful people here who will answer it.

I searched the forum, and found that your recommendation to search the forum has already previously been made.

Yeah, there's just a lot of info already here, but a lot of folks don't realize that initially. Even if a lot of people respond to your question, it's still worth searching. Chances are you'll find something in past threads that isn't in any replies to your query.
