pros, easy to clip into, very secure feel, lots of float for easy on the knees riding. cons, extremely clunky cleat. i have speedplays x2s on my dedicated training bike, ie, riding for ridings sake. forgot them if you are even thinking about commuting with them or intend on alot of stop and go situation. if thats the case, just go with crank brothers or spds and a shoe with a recessed cleat.
