Zipp 404 Rear Wheel With Powertap 2.4 Review this store Cycling Zipp Buy now. Pay later on Zipp 404 Rear Wheel with PowerTap 2.4. Zipp 404 Rear Wheel with PowerTap 2.4: 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. Clincher Wheels: 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 tyres and the reliability of an aluminium braking track. Plus, Zipp's M2CM technology maximizes rim strength and durability by fusing the aluminium 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. Tubular Wheels: For 2009 the 404 tubular wheelset is faster than ever with the third generation of our patented ABLC dimpling pattern and a new fully toroidal rim shape derived from the 1080 and Sub 9 projects. Refined through over 100 hours of wind tunnel testing during co-development with the new 808, the new 404 shows reduced drag at every angle from 0 to 30 degrees. The new tubular rim shape also offers the benefits of added stiffness, due to a slight widening of the rim, and better braking, with a slightly angled brake track. We've also taken similar leaps forward with the new 88 and 188 hubs that are smoother, stiffer, and more durable than ever before. Even with all these upgrades, there is no weight penalty. The 404 Tubular set tips the scales at just 1232g per pair with 16/20 front/rear spoke counts. Like all our tubulars, the 404 is built with our Carbon Bridge technology that dramatically increases impact resistance with a Kevlar thread running perpendicular to the carbon laminate. Between those layers of carbon lies our VCLC system, which uses a shock-absorbing material to reduce vibration by 10% and keep your wheels glued to the pavement under all conditions. Saris PowerTap: Weighing in at only 416 grams, PowerTap SL's Shimano or Campagnolo compatible hub can be used with virtually any wheel. And because it's so lightweight, it's perfect for racing as well as training, so you're constantly gathering performance data. Store up to 15 hours of data and unlimited intervals, with the ability to view past intervals while you're riding. And with the customizable display you'll never be more than a glance away from knowing your ride metrics. Simultaneously view power, heart rate and cadence-or mix it up further by viewing speed, distance or elapsed time. Compare heart rate to power output at any time or use the heart rate monitor off the bike for other endurance sports. The choice is yours. And so is the power to perform. All 2009 Zipp wheels (Excludes Disc Wheels) come with Steel Skewers & valve extensions.
