I currently have SPD pedals on all of my bikes. I've stuck with them so far as they worked relatively well and I couldn't justify having two types of shoes.
I can justify two types of shoes now.
These pedals/shoes/etc would be for my road bike and likely used on the track as I am going to spend a bit of time at the local velodrome this winter. My primary criteria is probably strength, with price second. I'm a sprinter and saving money is always good. Weight doesn't really matter at this point.
The Look and Shimano road pedals look good, but they have a number of different models across the board. Any suggestions or ones to stay away from?
