Match your hubs — it's the right thing to do.
Match your PowerTap G3 with the PowerTap Front Hub to give your bike a more finished look. Your bike will look better. You will feel happier. The world will be a better place.
For years, PowerTap had a problem. Not only was its powermeter hiding underneath a rather bulky rear hub, but the hub didn't match any front hub on the market. Cyclists pretend not to be a vain lot, but woe is the rider who dares riding mismatched wheels on the Sunday parade/hammerfest. So, PowerTap did the smart thing and designed a front hub that matched its powermeter rear hubs. Originally, it had carbon fiber windows to match the aesthetic of the rear hubs, even with the same graphic treatment. And now that they've evolved from the windows, the front hub has as well. The new hub lost 27g in weight and it received a new 10mm diameter axle — replacing the previous 9mm axle. It's both lighter and stiffer, which is always appreciated. In fact, the hub tips the scales around a svelte 97 grams.
The hub shell is constructed from aluminum and the hub features an aluminum axle that runs on 6901 sealed bearing cartridges. The flanges are drilled for 20, 24, 28, or 32 spokes. The spoke holes are 2.5mm in diameter, so just about all conventional J-bend spokes will fit. The spoke holes aren't slotted, nor is slotting recommended. The hub is able to be built into a wheel with either radial or crossed spokes. For home wheel builders, the measurements are as follows: hub center-to-flange distance is 34.4mm on both sides and the flange diameter is 38mm.
The PowerTap Front Hub may have "power" written on it, but it neither takes nor transmits power readings. It's available in the color Black, and it does not include a quick-release skewer.
