Just like the title says, I'm looking to get my first set of clipless pedals and shoes, and I need some help. I'm not really sure what I'm looking for. I know there are MTB pedals and road pedals - what's the difference really? Seems to me the MTB pedals are smaller. Any brands that are great? Ones to stay away from? Anything that's particularly better for us bigger guys? Also, I'm not too sure about the cleat types, but it seems that the SPD type are pretty popular.
And then there's shoes. I think I want road shoes, unless someone can talk me into MTB shoes. And I'm looking to do this on the cheap. Maybe about $150 for the whole deal. I found a pair of Diadora Sprinter road shoes for $50, but only is silver. I've found some stuff at Nashbar and Performance Bikes. Is there any other places that I should be looking? Links would be helpful too.
