PowerTap G3 AMP 50 Carbon Clincher Wheelset

When it comes to aerodynamic benefits across flat or hilly terrain, we find that 50mm rims tend to hit the sweet spot of maintaining forward momentum, negating drag, and keeping handling predictable and intuitive in crosswinds and less than ideal yaw angles. On the power measuring end of things, PowerTap's G3 hubs are virtually synonymous with counting watts. Of course, neither feature is useful without the engine, but the PowerTap G3 Amp 50 Carbon Clincher Wheelset provides a race worthy platform to efficiently transfer the engine's output into forward momentum while accurately quantifying that output in terms of watts. The G3 rear hub at the wheels' heart combines eight strain gauges with a claimed 1. 5% accuracy rating, equaling the industry standard in terms of numbers you can be confident in. It broadcasts these numbers with the ubiquitous ANT, so chances are good that your current head unit is already compatible with it, eliminating the extra 300 tax required by other models in order to buy a proprietary computer to bring your cockpit in line with your power meter. Changing the battery, updating firmware, or servicing the unit can all be effected in minutes with the use of PowerTap's handy little tool, making this one of the most home mechanic friendly power meters on the market. The hubs are laced to 50mm rims built by Amp, a smaller manufacturer based in England whose focus is more on value than name recognition. This focus manifests as cost savings in the four digit range when compared with G3 equipped carbon hoops from manufacturers whose decals add a premium to cost. The wheels are anything but bargain bin, though. In addition to the depth's obvious benefits, the Amp 50s feature a slightly rounded spoke face, which in our experience cuts down on the violent lateral forces of crosswinds and yaw angles. Like with the more expensive brands, the rims also boast width, sitting at a healthy internal width of 17mm. Wider rims increase structural inte...
