DT Swiss provided the Scott-Swisspower team with 650b carbon fiber tubular wheels. Given the expense of cutting molds, readers should take this as a indication of the company's commitment to the format.
Interesting, wasn't somebody recently asking about carbon 650b possibilities (If DT can do it, ENVE can do it clincher/UST-Tubeless)?
