To show how the clipless mentality can affect our thinking, I had a bike fit pro tell me that he feels safer on slippery surfaces (even in light snow) with clipless because he has better control of the bike. I just don't get it.
As one who has had a serious fall after riding clipless for several years, I can tell you that anything mechanical can malfunction. When my right foot wouldn't unclip, I went down big time and required medical attention. It probably doesn't happen often, but when it does the consequences can be serious.
It's always good to have choices, and I respect those who prefer the clipless route. I just think we should be honest about the benefits and disadvantages when we discuss this important equipment decision.
