Hi All,
I used to use 700X23 foldups and sure the ride was good but lots of flats. About a year ago I went to a 700X28 conti 2000 and that was the end of the flats. Its a great tire and really like the range from 90psi to 120 psi. Usually I run them at around 100 psi. They feel as fast as the expensive foldups and alot more sure footed on any sand or gravel you might hit on the road. If you are running a time trial or you live to break away in the hills then by all means use the foldups but for going down the road ditch the 23's and use 28's.
