If you want to check out a good bike blog, check out Dmitri's "The road to SS hundies". He's gotten into riding in a big way and is chronicling his efforts to step it up and ride several hundred-mile mountain bike races (hundies) on his singlespeed. (SS) He's also very active with the Philadelphia Mountain Bike club, organizing and working on trail maintenance days, which is something all mountain bikers should strive to get involved with.
