PowerTap G3 Rear Track Hub

The CycleOps Power Powertap G3 Track hub brings power measurement to the Velodrome for real time performance measurement. In addition to being lower weight, the new G3 hub also has a smaller profile with a stealth black finish. Powertap's excellent reliability has been further enhanced with now field-serviceable electronics that deliver better signal strength. One of the less talked about improvements is the wider hub flange spacing which contributes to more even left/right spoke tension thus building into a stronger, longer lasting wheel. Requires G3 track cogs - 14t,15,16 available sold separately.

The G3 hub is packaged as a hub only. It is ANT+ compatible for use with Joule, Garmin or any other favorite ANT+ computer. Some of the other optional accessories include a matching G3 front hub, and a heart rate monitor strap.
