For road pedals...if you are new to them...I would recommend something along the Look platform. By that I mean Look Keo series or Shimano SPD-SL series pedals.
Many reports indicate very poor life with the keo series cleat. Culiminating with CyLowe97 breaking one with few miles on them while on a ride with me once. Not nearly as durable as their old Delta series, but more than adequate if you pay attention to them.
For this reason I tend to recommend the Shimano SPD-SL series pedals. I would purchase them from probikekit.com (PBK).
Welcome and enjoy.....
....oh and before posting your first "I fell over" thread I would recommend simply searching for them and reading to your heart's content. It happens to everyone...eventually.
