"The essence of ZIPP Never count out the 404. Our most popular wheel has carried cyclists and triathletes to victory from the Alps to Kona, and the 2009 version is faster than ever before. The clincher version of the 404 uses the same go-anywhere, win-anything 58mm rim depth of its tubular brother, but with the everyday convenience of clincher tires and the reliability of an aluminum braking track. Plus, Zipp's M2CM technology maximizes rim strength and durability by fusing the aluminum hoop to the inner carbon section. ABLC dimples, VCLC vibration-reduction technologies, and the new 88/188 hubset round out the 404 Clinchers' 1615g total package with 16/20 front/rear spoke counts. True, they're heavier than tubulars and they lack the new rim shape, but they are still lighter and faster than many SL wheels on the market. But if glass and potholes factor into your rides, the peace of mind is well worth it.
