In 2005 we introduced the world’s first-ever wireless powermeter – and we’ve been striving to improve upon it ever since. Enter the G3, the third generation of hub-based powermeters.
The G3’s design allows for a simple, straight-forward way to measure power. By mounting the strain gauges in an area where external forces, such as spoken tension, cannot impact power measurement, the PowerTap G3 is able to deliver +/- 1.5% accuracy ride after ride. More than just a powermeter, The G3 delivers speed, cadence and power with pin-point accuracy all in one product. And its ability to be easily switched between bikes means you’ll never miss a watt.
