Heh heh - it is odd. Bought the pedals/shoes online about three weeks ago, first pair were a size too small, so they had to be shipped back and exchanged. Finally received the replacements last night. In the interim, I fell in to a PowerTap Pro (wired, couple years old) - I didn't buy it, a client gave it to me. He had replaced it with an ANT+ unit, and didn't want to go through the hassle of selling it. It's laced to an Open Pro rim and he left the Dura Ace cassette on there, too. Not bad, for free.
