CycleOps PTG3/Zipp 101 Clincher Rear Wheel $0.00
Featuring Zipp's 101 alloy rim paired it with the most advanced Cycle Ops PowerTap hub to date, the PowerTap PTG3/ZIPP 101 Clincher will make an excellent training tool. CycleOps completely re-imagined the design of previous PowerTap models, and improved multiple aspects ranging from rigidity to functionality. The new PowerTap G3 Rear Hub is a power meter on a diet.
An 80-gram weight reduction from the popular SL+ makes the G3 rear hub the lightest power meter in the world. CycleOps improved on the rigidity of previous models for the G3 by shrinking the hub profile and widening the flanges, ending the days of heavy, stiff, paint bucket-sized rear hubs. 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. With the new positioning, it's now possible to remove the electronics for service without swapping out the entire wheel, equating to 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 or any computer unit that translates ANT+(note that it doesn't work with Yellow CPUs.) The G3 is capable of storing up to 15 hours of data in one-second gathering intervals, and up to 30 hours of data in two-second gathering intervals. The G3 design still has a 'torque tube' with eight strain gauges, yielding measurements accurate within +/- 1.5% between 40 and 130 rpm.
The Zipp 101 Clincher does what Zipp has been doing with all their wheels: shattering preconceptions en route to making an amazing wheelset. The 101 looks like their 202, but it isn't just that rim translated into aluminum. It has its own shape. It's 30mm deep and 24.5mm wide, so both shallower and wider than the 202. The shape is designed to work best with clincher tires and to find the sweet spot between aerodynamics and light weight. It's toroidal, like most of Zipp's carbon-rim tubulars. The brake tracks are not parallel like on most wheels, but tip inward ever so slightly towards the tire.
The Cycle Ops PowerTap PTG3/ZIPP 101 Clincher Rear Wheel is hand-built in the USA. The rear wheel is available to fit Campagnolo or Shimano/SRAM cassettes.
