I sometimes commute to work on a fixed gear track bike with 23c tires. I had it set up with a single brake on the front wheel. I had two similar accidents. The first involved a slick, frosty greenway. The second was on a slick, muddy greenway. In both accidents, I grabbed too much front brake in a turn and had my front wheel slide out from under me. Both accidents were the result of user error and poor bike handling.
