Weight wise, at 230g for 25`s, they are still 90g lighter than the Conti Ultrasports I had been using and they had little puncture protection (or were cursed!), so I`m still a winner weight wise. The new bike has very straight forks and I feel alot more road vibration than the old bike, which is tireing. My thinking is 25`s will give more comfort, more grip, lighter and more puncture resistant than what I currently have.
Just upgraded to a new bike. Stock tryes are Vittoria Zaffiro slicks, which I know are cheap tryes, but the last set I had were ok before I upgraded them so thought I`d give them a whirl. First two rides (45 miles each) and a puncture on each ride. Going to get a set of Conti GP4000S`s, but wondered whether getting 25mm`s would offer any extra puncture protection and would there be any noticeable loss of speed over 23mm`s. Looking to run 25`s through the winter and change to 23`s when season starts. A good plan? or just go with 23`s.
