Inspired by finnbow's cool thread, I though I'd start one on the much less frequent entity of rock duos. Here are some to start it off:
Royal Trux
White Stripes
The Black Keys
The Evens
Simon and Garfunkel (though I guess they are more folk than rock, and there are a ton of folk duos)
Suicide
Tyrannosaurus Rex (again more folk and less rock until they expanded and became T. Rex)
