Using the data published so far, the fastest tire was a hand-made clincher with cotton casing in a 700C x 24 mm (actual) width. However, since that was the only hand-made clincher in the test, it's hard to conclude much from that beyond that hand-made cotton casings are super- fast. (Pro racers have known that for a long time, almost all of them race on hand-made tires with cotton or silk casings.) Would a hand-made clincher with cotton casing in a 34 mm width be faster yet? We are working on that... Jan Heine Editor Bicycle Quarterly http://janheine.wordpress.com/ -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
