The SportContact in a 28mm turns any bike into a racer. All this added speed for your bike with zero detriment to puncture protection and reliability! Extremely fine and strong carcass plies, SafetySystem and puncture protection are all integral features of the Contact tire family. 80 - 85 psi recommended pressure.
I can't comment on the ride quality because I was not able to get them on my rims.
I have Alex DA-16 406 rims and just could not get that second beed on the rim. These rims have a fairly deep V, not quite a true deep V, but deeper than a box rim.
Too bad, because the quality of the tire looks quite good, and the reflective side wall was a nice plus.
Bottom line, if you have deep rims don't go there. If you have box rims, these may be some fast duarable tires for you.
Bottom LineNo, I would not recommend this to a friend
