Ignore them.

Seriously.

Getting a bike that fits is what you need.

After you settle on a bike, come here and ask about
any components you have a question about.

When you test ride (and don't buy a bike without one) make sure you hit
a pothole. That will tell you what the ride is like.

A lot of guys buy a frame that is one size small. After a couple weeks they
want to go fast and try to lean into it and find that it doesn't feel right.
