My first set of clipless peds were Shimano 747's I had them on my mountain bike and absolutely loved them! When I got my road bike my bike builder almost refused to put them on claiming no respectable roadie would have mtb peds on a road bike! LOL Well I did until I started having trouble with my mtb shoes giving me hot spots on my feet.

A pair of new roadie shoes and some Speedplay X's and I was back to square one with learning how to clip in and out all over again, the Speedplay's were definitely harder to clip in and out of. Now that they are older they are easier in fact almost too easy it's probably time for a new set of cleats!

I'm glad you found the Shimano's I'm sure you're going to love them for a long time to come. Happy spinning!
