i'll continue to be one of the few, riding tubular, dissenting voices. i find 28's heavy and slow. rather have the bars double wrapped to minimize road chatter and run 23's to
maintain what little nimbleness, acceleration, handling and lightness they give me vs 28's...or 25's. if all i rode were flats, i'd probably feel differently. if i'm doing a tour
with some/all roads i've never ridden, i'd be more predisposed to do 25's vs 28's. if i'm doing a road ride with a significant percentage (20+%) of dirt/gravel section(s),
then yes, slap on the 28's. i haven't found 28's (or 25's) to be less/more prone to flats or wear than 23's with the same manufacturer/model.
i run the 23's at 95-100 and weigh abo 180. to each their own...
