First, after a period of dithering that made Hamlet look like Rudy Giuliani, DG gets a road bike -- a Roubaix, no less.

Then he starts talking about going clipless.

He's worried about falling over? Hell, given the above I'm worried about an impending disruption of the space/time continuum!

DG, most everything people are saying is true but makes it sound a lot more complicated than it is (you know, like how difficult it can be to explain a simple procedure in words). You get the kind you like. If you have a hard time clipping in, loosen the tension setting. If your feet slip out too easily, tighten them. You may well fall a time or two when you forget to unclip. You will only hurt your pride. The upside of clipless -- the efficiency, the decreased fatigue, the decrease of apparent effort -- are all worth it in spades. When I got my first clipless pedals they were for my hybrid. It was as if I'd gotten a new bike. I would not be without them. Both my bikes have them. To clip, or not to clip? Go for it, Prince of Denmark.

(I prefer Looks to SPD, as do most of the roadies I know -- but SPD MTB shoes can be more "walkable". I just found it easier to position my foot for clipping in with the Looks. I think you'll like the SPDs.)
