Anyone have significant time on the 2006 Eurus? I had the older version and loved it (I sold it awhile back). I need a new wheelset (my OP's went to my Cross bike) and they look like they will due the job admirably. I still have a line on the closeout 2005 Eurus's for $499, but for $639, I can get the newer model. Any negatives about the 2006's?
