I have only been riding for a little more than two months, and yesterday was my first day with clipless pedals, and I did fall. I was using speedplays. I remembered to unclip each time I stopped - I actually fell trying to get in. I had the right foot clipped in and was trying to get the left one to clip and was concentrating too on hard on that and wasnt paying attention to my speed and I fell over to my right. No injuries, but it did hurt quite a bit.
