Well, if you are looking for road pedals and you want double sided, then Speedplay is the logical choice. If you plan on racing, buy Zeros. If not, then consider Light Action.

If you buy them, be sure to put Locktite on the the screws. If you want to walk in them, you could put Shoe Goo on the cleats which makes them real easy to wallk and they grip the road much better too.
