You know how when you have a stick shift car no one ever asks to borrow it? I personally think that having the 520's on my Trek roadbike makes joyriders think twice. For that reason I don't advise double sided split platform pedals. Full clipless or nothing. I can tell by the way most people worry about clipless that when they get them they are going to use them wrong! I pop my non-dominant foot out of the pedal at almost every intersection! Approaching train tracks? Clip out! Make it across and clip back in. That wasn't so hard. If you are routinely popping your foot out of the pedal AS you reach zero speed you are (MO) doing it wrong! Your foot should have been out of the pedal 100' earlier! "But that wastes ...what? Speed? Efficiency? You're in town! What speed? What efficiency? When you are out hammering on a State Park loop you don't need me to tell you that its ok to not worry about clipping out ever 100 feet ... do you?
