Sorry to hear about you going down. I went down on the the first bad day here in chicago. I was acutally laughing out loud to my self at the black ice that I was riding on. Then all of a sudden my bike was gone. I ride a raleigh rush hour. I was on skinny 700X23's. I have since bought some wider knobby tires. I hope you and your bike are OK. I never like to hear people laying their bike down, but I figure if you are OK then it was a lesson learned. I am sure I will be learning my fair share of lessons this winter
