Have an 06. Love it. I am not an experienced enough rider to comment on wheel sets, but with a good fitting, and changing the seat, I have ridden for over 5 hours (Metric century, slow metric century) without a complaint about the bike. I can complain about the rider, as this part of the equation needs much improvement. Is the 07 a triple or a compact?
*edit*
MSRP is $1850, $1100 is a screaming good deal.
