I commuted for about a year on a Klein Adept Pro with Hutchison Gold 1.25" (32mm) slicks. The bike was an XC race bike with very short travel - 2" in back (which I ran very stiff) and 80mm in front - with a lockout.
My commute was 11 miles each way on the West side of Las Vegas, with about 800' elevation difference. The bike did great. The fork lockout and tires (and, to some degree the quality of the frame) gave the bike a very responsive ride, but it was very comfortable, as well.

100% paved route.
