I just glanced over at Competitive cyclist, as far as clip-less pedals that I'm dealing with, they do not have that many different versions of pedals. They are basically Shiamano/LooK or the lollipop or egg beater. I still think that there is room for one more that is highly competitive in pricing and is the easiest to learn and continue to use.Only a few? Competitive Cyclist sells over 125 pedals on their website. Over 80 of those are two-sided pedals that are really quick and easy to clip into.
You're probably right. Clipping into ordinary pedals is so difficult, it likely took a former pro rider 4 or 5 attempts to successfully do it.
As a for instance in the Red Bull Bay Climb a group stops from a dead stop and races straight up hill. For this particular race to get in quickly would be a benefit.
