Zipp 404 defined
For 2010 the 404 tubular wheelset is faster than ever with the third generation of Zipp's 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. Zipp has 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 Zipp tubulars, the 404 is built with Zipp's Carbon Bridge technology that dramatically increases impact resistance with a Kevlar thread running perpendicular to the carbon laminate. Between those layers of carbon lies Zipp's VCLC system, which uses a shock-absorbing material to reduce vibration by 10% and keep your wheels glued to the pavement under all conditions.
ANT+ PowerTap (PowerTap SL+)
Weighing in at only 416 grams, CycleOps 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.
With the Zipp ANT+ Pro Pack you can 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.
