DESCRIPTION

The CycleOps PowerTap G3/Zipp 101 Clincher Wheelset is a trainer wheelset through and through. Combining the durability of aluminum clinchers with the technological capabilities of CycleOps' newest and lightest PowerTap G3 rear hub has created a new level of training possibilities. Just as the G3 is a hub full of surprises, the 101s are no ordinary rims. Used as the official training wheel for Team Saxo Bank and Cannondale's world-class cyclocross team, the 101 has proven it's as aero as it is versatile. If you need a durable PowerTap training wheelset from which you can seamlessly transition to your race-day 404 Firecrests, the PowerTap G3/Zipp 101 wheelset is the obvious choice.CycleOps completely overhauled the design of previous PowerTap models, improving aspects ranging from rigidity to functionality. An 80-gram weight reduction from the popular SL+ makes the PowerTap G3 Rear Hub the lightest power meter in the world. CycleOps improved on the rigidity of previous models by shrinking the hub profile and widening the flanges. With the distractions of weight and stealth design out of the way, CycleOps improved the functionality and accuracy of data gathering. For one, CycleOps moved the orientation of the electronics that transmit user data to the end cap of the freehub body, making it possible to remove the electronics for service without swapping out the entire wheel. This means more time in the saddle and fewer headaches. The new G3 is equipped with an ANT+ wireless transmitter that sends power, torque, speed, and virtual cadence data to CycleOps' Joule computer or any other unit that translates ANT+. Please note that the G3 is not compatible with Yellow CPUs. The G3 is capable of storing up to 15 hours of data in one-second intervals, and up to 30 hours of data in two-second intervals. The G3 design still has a 'torque tube' with eight strain gauges, yielding measurements accurate within +/- 1.5% between 40 and 130 rpm. Zipp's foray into aluminum clinchers resulted in a patented aerodynamic design that, compared to their closest aluminum competition, shaves up to 42 seconds over 40 kilometers. With first impressions like this, we're ready to let the Zipp 101 marry our daughter and take the keys to the sports car. The Zipp 101 shares many of the characteristics seen in Zipp's carbon series of race wheels. The 101 features a tunnel-tested, fully toroidal rim shape s well as many of the Firecrest's wider-is-better design features. Like the Firecrest, the 101 pays close attention to the degradation of airflow due to tire bulge at the rim. The solution is quite similar; a wider 24.5mm rim design that decreases drag while increasing lateral stiffness. The wide 101 design also decreases the occurrence of pinch flats, an optimal characteristic for any trainer wheelset. Ultimately, the Zipp 101 is the fastest aluminum wheel on the planet, and the preferred training rim for pros across the 700c world.The CycleOps PowerTap G3/Zipp 101 Clincher Wheels
