Cycling Media 360 (American)
2 Johns Podcast (American, but dont seem to be publishing any more, the back episodes are very enjoyable and some great interviews, dunno why they stopped, I wish they come back online)
Rouleur hosted by Jack Thurston describes magazine of the same name
THe Bike Show (British), deals with Britain's bike issues, has some good interviews, try listening to Just Ride interview starring... oh who's that guy who owns... that bike company... darn.
There are a couple of other american ones, cant recall the name, but I get the feeling the guy just says everything is fantastic (vertically compliant, laterally stiff) for anyone who sponsors on his show).
Oh yeah, I think there's one called The Round Table. Good varied views on that.
