Hey Sara-
I have crank brothers pedals on my road bike and love them. I have the candies, which a similar to the quattros, but officially a mountain pedal... the only real difference between the candies and the quattros is the platform they put over the egg beater part of the pedal (from what I understand).

I got a lot of good recomendations for these when I was first looking into clipless pedals, so went with them. However, when I got them the girl at the bike shop (who I had not delt with before) was surprised because she thought they were hard to smaller girls to clip into. They were a little difficult at first, but that is because I needed to wear the cleat in. I just sat in a doorway and clipped and unclipped a lot. Now they are super easy to get into, and I can still pedal quite easily without being clipped in like when I start from a stop sign or light.

As for getting out of them, so easy! So much easier than the SPD pedals on the spin bikes at the gym (though I am sure that is a really bad comparison). You don't have to tug at all, just rotate your foot outwards (or inwards, good if you are falling!) and you will slide right out.

On another note, your location says Northern Californa... where in N. Cal. are you? I am in Palo Alto, and there are a ton of other women on the boards in the bay area. You should come join us for a ride sometime! Despite that lots of them do crazy things like double centuries and bravet series they are really great with newbies!

Good luck, and hope to meet you soon!
