Three. The first was a classic clipless fall--stopped at a stop sign, and leaned the bike the wrong way. Skinned my knee. The second (on the same day) was pretty much me being stupid and trying to take too sharp a turn, and down I went. I count it as a clipless fall because if I hadn't been clipped in, I probably could have righted myself. Fell on the same knee, scuffed up my bar tape, bent my left brake hood in a bit, and knocked my front wheel out of true.
The last one...I don't quite know what happened, but I think I leaned the wrong way, then over-corrected at the last possible moment. I ended up sitting on the rear triangle.
