There’s only one rule at this irreverent rolling circus: one gear. Held each year in a new location, it wouldn't be hard to mistake the Single Speed Cyclocross World Championships for a drinking game surrounded by a bike race. Athletes in six categories, including a new women’s category unveiled last year, race ‘cross bikes with single-speed drive trains over a course that combines traditional ‘cross features with more whimsical elements—in 2011, racers faced a Le Mans-style start up a steep, muddy incline, a knee-deep water pit, and hip-high log barriers, although the extra fun parts change each year. Overall winners are required to get a SSCXWC tattoo, although last year's champs refused, sparking a controversy. Not racing? Don a costume and practice your heckling. So far, information on the 2012 event is sketchy, but it looks like the race will be held in Santa Cruz, California. sscxwc2011.com
