I will probably replace the 23mm tires with wider ones once the they wear out or if they prove to be flat-prone.

The old Dakota it's in front of is my 3rd commuter is worth less than the new bike [/QUOTE]

My wife changed over from 23's to Conti Gatorskin 28's last year and has yet to have a flat in a couple thousand miles of commuting/weekend rides. I've got about 2k on my Conti Touring Plus' and I think I'm a Conti lover for life!!
