REALLY like the Speedplays, doubt I am even going to try the Shimano 105s. They are going back or getting sold. Love the free float on the Speedplays, they feel a lot like my CrankBrothers MTB pedals oonly better. I really wish i did the road shoes and pedals sooner. It could be a placebo effect from new gear, but it just ft like it took less effort to maintain the same speeds as on the MTB setup I was using.
In addition to today being my first ride on road pedals it was also my first half century. Rolled jut over 50 miles on a very hill route in just over 3 hours. Time to sit on the couch and veg.
