I could be mistaken but from what I recall reading, there was a run of San Joses that came with the Pista wheelset. According to the website, it's not standard on the '07 model. I believe that demand for the bike was bigger than expected and they ran out of stock wheelsets; they used extra Pista wheelsets to fill the orders, but are back to the single-sided SS-only wheels. Again, I could be wrong.
