Had a 25 on the rear today (courtesy of moog, thanks ^_^) and the difference really noticible, maybe it was just the tyre, i usually run gatorskins (from what I hear they don't have a lot of grip) but these had a LOT of grip, I can see why people go for the 25/28s but i'll definitely be sticking with the 23s, more nippy and less grip (it's a good thing to me, don't ask why).
