The need for power isn’t just a roadie thing. With more and more mountain bike racers looking to wattage for training purposes, the off road power meter market is experiencing a similar evolution as road. For Powertap, that means taking their already popular mountain bike hub based powermeter and dropping a big chunk of weight. Compatible with both quick release and thru axles dropouts, the New Powertap G3 rear disc hub clocks in at more than 30% lighter than the previous model…
Having access to power is a great tool for racers but not if it comes with a big weight penalty. That’s exactly why PowerTap redesigned their hub to remove an impressive 180g. Now checking in at 350g for the hub, PowerTap also provides the weight of the 160mm brake rotor at 150g. Due to the design of the hub the G3 uses a proprietary brake rotor with a larger bolt circle that is included with each hub.
Offered in 24 or 28h bodies, each hub is shipped with end caps for both 142 x 12 and 135mm quick release dropouts. Using a straight pull, stacked lacing hub flange design, the resulting build has been tuned to be as stiff and efficient as possible. Equipped with a 6 pawl freehub mechanism, hubs are available with either Shimano/SRAM 10/11 or SRAM XD bodies. PowerTap G3 hubs include both ANT+ or Bluetooth SMART connectivity and offer a 1.5% accuracy rating. Sold with a 2 year warranty, the G3 retails for $989.99.
