http://www.jensonusa.com/store/sub/1...0&pricemax=200 Serfas ties are very good. I have two of the wire bead tires with 2800 miles and just showing a noticeable flat spot. Can't beat the price of $9.99. I've also recently bought the Serfas RS folder. Very light and smooth rolling tire but too soon to tell about length of service.
