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. Naturally, CycleOps has reinvented the wheel, quite literally, with the PowerTap 65mm G3 Carbon Tubular Wheelset. Featuring drastic weight reductions, technological breakthroughs, and a partnership with the legendary rim manufacturer, Enve, 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 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 either 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.
CycleOps partnered with the cutting-edge wheel manufacturer, Enve, to create the rim sections for the PowerTap 65mm G3 Carbon Tubular Wheelset. A true legend in carbon composites, the 65 has been touted as the 'Founder's Favorite' of the rims in the Enve arsenal. Enve's most versatile rim, the Enve 1.65 Tubular is the preferred rim for professionals for everything from climbing to time trials. The funny thing is that pros all say that it's the best rim for whatever discipline they've been using it for. With a 65mm rim depth, the wheelset offers weight savings in comparison to many top wheelsets, like the HED Stinger 4 Carbon Tubular and the Zipp 404 Firecrest Tubular.
Each PowerTap 65mm G3 Carbon Tubular Wheelset is hand-built with DT Swiss Aerolite Spokes, a 20/24 spoke count, and features the new 99-gram CycleOps Front Hub. The new front hub design features a beefed-up 10mm axle, an aluminum hub shell, and 6901 aluminum sealed bearing cartridges.
It shouldn't surprise anyone that the partnership between CycleOps and Enve, of which the PowerTap 65mm G3 Carbon Tubular Wheelset is the result, would be something extraordinary. What might be surprising is how remarkable this wheelset is, even for them. The wheelset is available with either a Shimano/SRAM or Campagnolo compatible freehub body.
