Review on Pair of Continental Ultra Sport III 700x28 Folding Tires, Black/Black with PureGrip Technology by Matthew Perez

My first impression after installation was wow. My first impression during and after my first ride was what I was doing and why I switched from 25 to 28. My gearing and shifting was too hard and I couldn't find the right rhythm. I was thinking of going back to the 25th when I caught up with two cyclists at 17mph. Then we move to 21 mph, and then the 28th makes sense. 28ers ride faster, roll over bumps more smoothly, are more stable and less twitchy than 25ers. My second ride was great and now all of my 28 rides are amazing. I would recommend going from 25s to 28s.
