G3 AMP 35/50 Carbon Clincher Wheelset

For around the same price point of your typical carbon clincher wheelset, you could get the G3 AMP 35/50 Carbon Clincher Wheelset from PowerTap instead and get the added bonus of training with power. It's hard to imagine a product that has revolutionized the way people train and race more than the CycleOps PowerTap. Allowing users to monitor critical performance data in both real-time and post-ride has pushed athletic evolution leaps and bounds into the future. Now, CycleOps offers a race ready wheelset, featuring drastic weight reductions thanks to carbon fiber, technological breakthroughs, and the handling benefits of a light, lower profile front wheel and the improved aerodynamics and stiffness of a 50mm rear. Thanks to its racing a training ability, this wheelset is the most versatile and advanced PowerTap wheelset ever created.

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 one of the lighter power meters. 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+ and Bluetooth wireless transmitter that sends power, torque, speed, and virtual cadence data to either CycleOps' Joule or any computer unit that translates ANT+ or Bluetooth. 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.

CycleOps' AMP rims feature a wider width to create a comfortable ride with lower rolling resistance and better aerodynamics with today's wider rubber. And with all of that speed, excellent stopping is a must. AMP rims feature CTg braking technology that virtually eliminating the pulsing caused by heat build-up. Rims and brake pads run around 100 degrees cooler during use for better durability and reliability.

Each PowerTap G3 AMP 35/50 Carbon Clincher Wheelset is hand-built with DT Swiss AeroComp Spokes, in a 20/24 spoke count and a 99-gram CycleOps Front Hub. The front hub design features a stiff, 10mm axle, an aluminum hub shell, and ABEC 5 sealed cartridge bearings.
