About three weeks ago, I was heading home from work and and ran into a parked car. At first I thought I was looking down at something on my bike, but I've ridden by the spot since, and now believe that I was looking back to see if it was clear to move out into the lane when I hit the car. My depth perception might have been altered by the prescription bifocals I was wearing or they may have created a blind spot where I didn't see the car.
I think I was going 10-15 mph. I went over the bars and into the back window, shattering it with my head and landed along the car on the street side. I left the scene in an ambulance and spent the night at UCDMC. Nothing was broken and my helmet probably saved my life. I walked out of the hospital the next day with a total of 4 stitches, a broken helmet, and a cdrom with some really cool xrays. My face was pretty cut up and my legs were severely and deeply bruised, but I'm pretty much healed now. My homeowners insurance paid almost $4000 to fix the person's car.
My Surly frame was bent at the down tube where the cable guides are and also where the top and head tubes meet. My handlebars were just slightly bent, and one brake lever was twisted sideways. Other than that, there was no damage to bike. The front wheel stayed true and round, the tire did not flat, and I still haven't decided if the fork is bent at all. I didn't even damage my cyclocomputer.
Surly has offered to replace the frame for $290 plus shipping and tax. But I was thinking of going a different route even before the crash. Having a fixed gear option on my cross bike is no longer a necessity, and I was sort of thinking about eventually getting disc brakes. Since I commute in the rain, an aluminum frame would be one less headache in that regard.
As for size, the Surly was a 60, with a 60cm top tube. My famous rainbow fixed gear, is a 61 with a 59cm top tube. I also have a Miyata 110 with a 57cm top tube. The Surly always seem a little big. I could probably go with a 58 or so, but I like to have my bars about 1" below my saddle, so I tend to like bikes on the larger size.
So that's about it. Oh, here's a picture...
