I shopped victoriously for a single-speed 29er on Ebay today. Not because I really want to ride a single-speed, but moreso because I'm tired of ruining drivetrain components in the winter muck. It's a brand-new 2007 Kona Unit 29er with a RockShox Reba SL 80mm suspension fork and Avid mechanical disc brakes. The bike is steel -- that will be a first for me -- and is a 20" frame so I'll probably have to swap out the stem to shorten it up, but it should be a great -- cheap -- winter bike for what I ride around here in the wet season.
Now that I think of it, I imagine this bike might have something to do with my sleep-talking inquiry into Kristin being kicked by purple penguins.
