Yeah yeah, I know it's too early to be thinking about winter already, but I just got the hub and rim (700c Rhinolyte! Eyeleted and $30!) for my fixed 69er commuter experiment and I'm thinking about tires. Is the Nokian "Extreme" the only one out there? I still havn't made a decision between a 29er or a skinnier, lighter 700c stud but do any of you know of any other fatty options?
