I just bought my first road bike in twenty years, and I am now looking for clipless pedals. Bike is a Specialized Secteur, that I will be using for long distance fitness riding, and sprintn distance tris and duathlons. Centuries, MS 150 etc. I am looking for your thoughts on clipless pedals. Since I have been in the market last, Speedplay and Crank Bros are new to me.

Do the different styles have better purposes for different types of cycling? My initial thought is that for longer distance a bit of a platform is better to disipate vibration. Dont want to break the bank, so overall value is a concern.

Thnks in advance.
