I have a CAAD5 w/Campagnolo Centaur triple - all purpose, trusty steed. I put $30.00 Bontrager 28mm tires on it and they just barely clear the brakes. I'll keep this one forever. It rides just like I prefer. It's rugged, handles gravel and rough road surfaces, fun to ride, will go about anywhere. After the 28mm tires, it's about upgraded all it's going to be. The bigger tires really made an improvement in the fun.
