well received my XS friday before last and man this thing rocks. I've been riding back and forth to work each day with some casual rides on the weekends. only 50+ miles so far and no issues to speak of. Oh, got a flat this past friday and fixed it at work. need to invest in some flat protection since the tires are pretty thin. very, very happy with my purchase and Sondors was just about right on time with my shipping estimate.
