CycleOps Powertap G3 Wireless Hub

The CycleOps PowerTap G3 Wireless Hub is unique some of the other PowerTap offerings. Where the in advance generation hubs stood out with their larger-than-normal diameter, this one has a power meter disguised inside a traditional-having a look 57mm flange diameter and subtle matte Black finish. It is also significantly lighter.In other words, it looks and feels like a standard hub. Chris King hubs have a flange diameter of 53mm, so the G3 is only a teeny bit larger. And for reference, hubs of Ultegra quality are around 350g, so the 325g G3 Hub is lighter than all however the super-premium rear hubs available on the market. There used to be a sort-of dorky virtue in having a bulky hub sporting carbon that shouted ‘power meter,’ and the unique aesthetic in their older hubs functioned as advertising for CycleOps. On the other hand, their power-measuring hubs were so obvious it incessantly acted as an impediment for lots of potential users. The sleek and stealthy design of the G3 gets rid of the distraction.Knowing the value in weight reduction and stealth measuring, CycleOps looked at easy methods to fortify their power meter with none compromise in performance. The G3 design still has a ‘torque tube’ with eight strain gauges, yielding measurements accurate within +/- 1.5%. But they did not stop there.Relatively than keep the electronics permanently affixed to the hub shell, they determined to build the electronics into the end cap. It is a big change, and a welcome one. By having a removable electronic element, it signifies that if there is a wheel-based problem with power readings, you’ll get a spare cap and install it to keep on training Relatively than sending your wheel back to CycleOps and looking ahead to them to determine the problem. Any other improvement that comes with this change is that a single CR2032 watch battery powers the transmitter; these batteries are easier source and replace than the two 357 batteries found within the older hubs. The 2032 must last for approximately 300 hours of riding.
