I'm about a month into my first road bike and I have been able to ride quite regularly. I believe I am getting ready to clip-in to my pedals. I have read through several forums, but have not been able to completely figure out how it works. Is it as simple as buying the special pedal and then buying shoes? There are also a few acronyms that I am unsure of like STD, etc. Can anyone please help me with what I should know before I begin searching for the pedals? I would like to know what are the good brands, styles, and what all goes into to the pedals and shoes?
