Peter DiAntoni publishes Cog Magazine, a print publication featuring good quality photos of fixed gear bikes and the people who ride them around the world. Cog has recently released their First Year Anniversary hardcover edition that I think makes a pretty nice gift for the bike geek in your life.
The magazine edition of Cog is available for free at a handful of bike shops throughout the United States, Canada, the UK, Germany, Sweden, Denmark, France, Hong Kong, Japan and Taiwan.
