Product DescriptionThe CycleOps PowerTap G3 Wireless Hub and the Zipp 404 Firecrest Carbon Clincher are a match made in heaven. Both are revolutionary, both are incredibly light, and both are the stiffest products in their markets. Combined, the PowerTap G3/Zipp 404 Firecrest Carbon Clincher wheels are a Leonardo da Vinci-esque blend of science and beauty that 'moves' you.CycleOps completely overhauled the design of previous PowerTap models, improving 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 of 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 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 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.A number of components went into making the Firecrest 404 Carbon Clincher the strongest and fastest clincher in the Zipp arsenal of 'Speed Weaponry.' First is the Multi-Material Co-Moulding process that permanently fuses a sub-200-gram aluminum hoop to a dimpled carbon structure that acts as a leaf spring for road vibration and impacts. The next step in the process is the implementation of VCLC, which involves the insertion of a visco-elastic material between carbon laminates in the rim, which delivers a ten percent reduction in road vibration. When it came to carbon resin, Zipp faced obstacles in relation to applied heat. It found that clincher rims handle all of the air pressure along with the tire, resulting in catastrophic failure when over-heated. Part of the solution came from the development of the Firecrest Clincher rim shape, and the other came out of an exclusive deal with a Formula One carbon resin manufacturer. Together, they worked out a new resin that improves heat dissipation enough to pass European safety testing without setting limitations on rider weight or brake pad options. Zipp's unique Firecrest design is steeped in a wider-is-better ideology. Zipp found that a wider
