The PowerTap hubs line has really focused on the electronics and engineering coupled with unparalleled accuracy for a hub powermeter. The G3’s brains have now been fit into the cap on the non-drive side. That might not sound like a big deal, but it is, because if these ever need servicing you’re not losing the whole wheel, just a cap. Now combined with the DT Swiss R460 rim, PowerTap’s training wheel just got better.
