Our Excel Sports Boulder hand-built PowerTap G3 hub with a HED Belgium C2 rim marries two of the latest and greatest developments in both rims and hubs. The light and reliable PowerTap G3 hub takes care of precise power measurement with virtually no weight penalty and the highly sought after HED C2 Belgium rim provides excellent strength plus the enhanced ride quality and handling that a 23mm wide rim offers.
The G3's 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.
We hand build this wheel in-house here in Boulder, Colorado by our DT Certified wheel builders who have literally built thousands of successful wheels. Our wheels are built precisely to the rim manufacturer's recommended spoke tensions, pre-stressed and perfectly trued. If you want a G3 hub with a different rim/spoke combination please call our friendly and knowledgeable staff at 800-627-6664 for a quote.
The G3 hub is ANT+ compatible for use with Joule, Garmin or any other favorite ANT+ computer. Select Shimano for compatibility with all Shimano and SRAM cassettes up to 11-speed or Campagnolo for compatibility with Campagnolo 11, 10 or 9-speed cassettes.
Rim strips are not included. We recommend using Zipp or Continental 18mm rim strips with the Hed Belgium C2 rims due to the wider 23mm rim profile.
