I went to the LBS yesterday and got my new Sidi shoes for riding. While I was there I talked to a guy that was a pro cyclist and he talked me into clipless pedals. I went back today with bike and got a set of shimano M324 pedals and used them today for the first time all I can say is this is great. Cannot believe the difference in my pedal power and how I felt after riding for 10 miles today. No feet burning like before and the back and legs are not sore at all. I know that it will take time to get really broke in to these pedals but thats ok I am a quick learner and I feel good as I didn't spill my bike at all the first time out with them on.
