Ok I'm sure this has been covered before (and I will commence searching after I post this) but I want know what I should look for in a clipless pedal. Roadbiking, 70-100 miles a week, I don't want to spend a fortune on pedals and shoes but don't want to buy junk that won't give me a fair trial. I have always had toe clips but am thinking I should give them a try. Any thoughts would be greatly appreciated.
