Straighter, stiffer, stronger.

PowerTap has been designing power hubs for over 15 years — adapting to changing technology, going from bulky wired units to streamlined wireless models, it keeps ahead of the curve in terms of power metrics. And compared to many crank-based systems PowerTap hubs are not only less expensive, they are also more easily swapped between various bikes. The GS 24-hole hub with DT Swiss internals is its latest creation.

The "S" in the title stands for "straight-pull" and as you would expect, the spokes on the hub are indeed straight-pull. To that end, PowerTap worked with DT Swiss to completely redesign the hub body. Although the electronics are identical to the G3 hub, and the caps are interchangeable, the body itself looks completely different. The idea behind the hub was to up the ante in durability and performance. The GS series is not a replacement for the G3, nor is it the next iteration; which is why it's not called the G4. The bodies are DT Swiss' 240 straight-pull shells and come with DT Swiss bearings for an even smoother riding wheel.

Like the G3, the electronics are built into the end cap. This means that if you have wheel-based power reading problems, you're able to send just the end back rather than your whole wheel. Additionally, it is powered by a single CR2032 watch battery, which is easier to source than the two 357 batteries in older hubs. It lasts for about 300 hours of riding.

The GS features an ANT+ transmitter so that any compatible head unit is able to read the metrics. The "torque tube" design of the hub features eight strain gauges that yield power measurements within +/- 1.5% accuracy.

The GS 24 Hole Straight Pull Hub w/ DT Swiss Internals comes in Black. It is available with either a Shimano/SRAM or Campagnolo freehub. Please note that it does not include a skewer.

Hello, I just inquired on Powertap's website, and they said that this hub (GS) is now compatible with Ant+ and Bluetooth out of the box. The description here however says Ant+ only. Is this GS hub on Backcountry the current model sold by Powertap that is comptaible with Ant+ or Bluetooth out of the box, or is your description accurate and this GS is a previous model that is only compatible with Ant+ out of the box? THANKS!

I ordered one the other day and it was Bluetooth compatible right out of the box.

Had been waiting for this "bullet- proof" Powertap hub with DT Swiss internals for sometime now as have been totally satisfied with all my previous and current DT Swiss hubs. Purchased in Oct., built it up with a Reynolds Assault 40 C/F rim and put approximately 3000 miles of hard riding on it in 3 months. Everything worked flawlessly until a screeching / grinding sound began under heavy torque - much like a BB issue. After servicing the Campy U/T BB cups and removing / cleaning the cassette to no avail, it was traced to a dirty / dry internal free-hub body that would not let the pawls engage sufficiently. After cleaning and lubing, it works perfectly again. I think DT Swiss is notorious for not lubing their F/H bodies sufficiently coming out of the factory I will of course, monitor its long-term performance.

April 2016 Update: I've had to replace the electronics ring twice. Last year (with about 10, 000 miles on the hub) the calibration went awry and Saris replaced the ring. Then within the last month I started to get a battery drain and it was replaced free of charge again. Other than these minor inconveniences, I like the hub (and BTW, the price keeps coming down!)

So Far So Good But...

I've got similar issues with mine. Same amount of miles, under torque, same grinding noise.
