I have the Look Keo Sprints. This is my first experience with road pedals after using and loving my SPD's. I like the SPD's for the simple reason I can put my foot in the clip- bam and done and on my way-I have access to both sides of pedal. The sprint took me a little to get used to, only one sided, and just wasn't sure. After riding several miles and times, the more I got used to the pedals, the more I liked them. I just have to remember to put my foot into place to clip in after the top of the stroke vs. trying to clip before the topstroke. there is a weight or something that makes it so the pedal won't swing backwards. It's a whole thinking process for me. I was used to MTB shoes and stopping with my whole foot. I have road shoes now and have to stop with my heel on the ground or I go skidding. Trial and error. I have kept the SPD system on my winter/bad weather bike though. I have not had any problems with the Keo Sprints at all. I like them.
