Keo Classics are good pedals but not the ideal choice if you're looking for lightweight pedals. I have a pair and they haven't been problematic at all. I do like the look of the Keo's from Europe as you have the option of a black pedal; here in the US only the dark gray option was available. If these are your first pair of Look pedals then remember that the red cleat has 9 degrees of float, gray cleat has 4.5 degrees, and the black cleat has 0 degrees. There are also two models of cleats: the Keo Grip and the regular variety. I'm using the grip model right now and it's a bit frustrating clicking into them because the grip doesn't make it a smooth process like those without it, though in fairness it does come in handy when commuting in the city where I often have to unclick and need a bit of traction in the cleat.
