This tire is amazing. The first one I bought I got down in Flordia right before the start of the gncc in West River Gate. The tire did amazing in the sands of Flordia. I then raced in Goregia, South Carolina, and went on a weekend long ride in the West Virginian mountains and the tire stuck to everything I could throw at it. The best part was THIS WAS ALL ON THE SAME TIRE!! After that first impression nothing has changed and this is the only tire I will race with. It finds traction on anything and is very flat resistant. Recently I started running the tire with the tubliss system and even love it more.
