I would appreciate some advice. I have been getting a lot more comfortable on my bike and have changed my mind. I would like to advance to a Clipless system. I am, frankly, afraid of falling, and the idea of not being able to get my foot out in time to brace myself, etc. is a bit scary. Are there recommendations for both a pedal system and a process for getting used to them? I am fortunate enough, where budget need not weigh into the calculation for this accessory. This one seems important. Again, I appreciate any insights. Thanks.
