Second on the Bonti tires. Have run a pair of R3's for 2 seasons with no flats. They also roll like crazy and have good grip. Just ordered a new set of Vittoria Rubino pro slicks however...have a friend that loves them and they were 1/2 the price of the Bonti's. Figured as the R3's are starting to flatten out in the middle it's just a matter of time..been loyal to them for 3 seasons however!
