Are you trying to sort out how best to maximise your training efforts and be able to quantify those hard miles in the saddle? Enter the Powertap G3 rear hub. Since 2005 Powertap has been steadily improving this hub and is currently on the 3rd generation. The G3 is a power meter with an impressive +/- 1.5% accuracy. It not only measures power but also tracks your cadence precisely.
The Powertap G3 hub weighing in at a mere 320 grams. Comes with a 2 year warranty.
The new field serviceable electronics run on one CR2032 battery. It's compatible with ANT+ or Bluetooth Smart devices. The cassette accepts either Campagnolo or Shimano/SRAM 11 speed set ups. Spoke hole options range from 20 holes up to 32 holes for a more stout training wheel. If you decide you'd like to have a matching set of wheels Powertap makes a front hub that shares the look of their rear one.

If you'd like the fastest version of a Powertap rear hub you'd be after the Powertap G3C. Things just got faster and a wee bit lighter with an upgrade to CeramicSpeeds ceramic sealed bearings. Its visibly distinguishable by the bright orange axle ends.

What to do if your bike is set up for disc breaks? Not to worry? Powertap also has models that will suit your machine perfectly. Available in 32 holes with either a 135mm Qr version or a 142 X 12mm thru axle configuration. Matching front disc hubs to boot! 160mm rotor is included in the deal. There's even a Powertap hub built just for track riders as well as a collaboration with HED for a solid disc rear wheel that incorporates the Powertap G3 hub. It has an alloy rim with a carbon aero centre section.
