Stock Schwalbe Duranos are toast. LBS recommends Gatorskins of course.
Cannondale super six, 100 miles a week, a few Olympic triathlons a season.
Trying to keep it light, never had a flat with Duranos but would like to see if i can upgrade now with a different tire. go to a 25 from the 23? has anyone had a noticeable difference going that route?
25 Gatorskin going to slow it down?
