cool. From my limited experience riding a few Cannondales once in a while, and my late 90s alu mtb, I'm sure you will appreciate those 38s. Watch the pressures and take advantage of the natural suspension of fatter tires, cuz this generation of alum frames tend to have a harsh side to them. If you ever want to try other tires, I highly recommend Schwalbe Supremes, really nice ride due to the thin sidewalls.
