This hand-built rear wheel features the crushing combination of a Beyond Black Zipp 404 Firecrest Carbon Clincher 20 hole rim laced 2x with DT Aerolite spokes to a CycleOps Power G3 hub. So you can get aerodynamics, low weight and uber-reliable power measurement. This means you can get all important race day data from super top-end racing wheel. Having power data can help eliminate surges for time trials and triathlons for better pacing and a faster overall time or let you be on the "number" that will send other racers off the back.
The 404 Firecrest's carbon clincher signature shaping is designed to optimize both halves of the wheel and balance the center of pressure. This creates a 58mm sectioned rim that is significantly faster than other deeper rims while handling crosswinds more like a box-sectioned rim. The 26mm width of the 404 also provide better tire performance and handling. The 404 Firecrest has been used to win countless races and is the perfect choice for the best balance of aerodynamics, handling and weight.
G3 hub is about 90 grams lighter than the Pro and is billed as the world's lightest power meter. Its 336 gram actual weight means there is virtually no penalty over a standard rear hub and weight savings is estimated at least 250 grams over crank-based power meters. This allows the weight-conscious competitor to use this hub on race day to record critical power information.
In addition to being lower weight, the new G3 hub also has a smaller profile with a stealth black finish. Powertap's excellent reliability has been further enhanced with now field-serviceable electronics that deliver better signal strength. One of the less talked about improvements is the wider hub flange which contributes to more even left/right spoke tension thus building into a stronger, longer lasting wheel.
The G3 hub is ANT+ compatible and can send power, torque, speed and cadence to a Garmin, Joule or any other ANT+ computer.
