http://bikesnobnyc.blogspot.com Probably one of the funniest blogs that I have come across. Bike politics in NYC, as well as product reviews and anything else. I have to chuckle at every single post.

http://www.cascade.org Cascade Bicycle Club. The largest bike non-profit in the Seattle area. Organizes rides, swap meets, and bicycle advocacy here in Seattle.

http://www.sheldonbrown.com The best single website resource for bike repair. It it where I first started for explanations, and still go to.

http://www.classicrendezvous.com One of my favorite websites for classic bike of all makes and models. A wonderful place to go and research old frames and components from the world over.

http://www.velobase.com Excellent database for older bikes parts of all kinds. Very useful for component identification and specifications.
