I have a Nashbar SS CX bike as a beater commuter. Shockingly nice for the money. Gorgeous deep blue paint, thin steel tubing...the saddle is even half decent for a stock saddle at this price.

It runs tall for its length though. Or it runs short for its height. The BB is high, the top tube slopes slightly, and the measurements for the seat tube are true. So my 52cm frame is quite a bit taller than my other 52cm bikes.

Edit: And disregard everything I said above. Looks like Nashbar doesn't have them anymore.
