I'm also a big fan of Fatty, Bike Snob NYC, and Large Fella on a Bike. A couple of others I check out frequently:

Unholy Roleur, a local DC-area guy who's got an attitude and wicked sense of humor similar to Bike Snob.

jacquiephelan.com, a female bike racer who writes about cooking and life in general, in addition to cycling. Funny and thoughtful.
