I'm riding a pair of Vittoria Graphene tires. Vittoria describes them as the next generation tire (my words), describing them on their star chart as being 4 out of 5 for grippiness, rolling resistance and several other characteristics. (I've tossed the packaging.). My experience with several hundred miles lives up tp their claims. I"m riding the 28c tires. Cushy, fat ride. They roll really nicely, feel great on corners and on iffy pavement. Confidence inspiring like the green Vittoria Paves were except I can see already they are far less prone to cutting.
So, for me, they seem to be $70 tires with just one drawback. $70. But maybe they will last long enough to be $70 well spent. Another plus, one that has me wondering why it took 25 years, ribbed tread. Us old farts who rode ribbed tread sewups BITD knew it was wonderful. Good to have it back.
