Powertap G3 hub built on a velocity rim. 32 spoke hub so can be moved to any rim with that spoke count.It is 9/10 speed shimano compatible. I don't know if it will work with anything else but I've had both 9 and 10 speed shimano cassettes on it. It is used but in perfect working condition. I just don't ride that bike anymore.Comes with Powertap's Joule computer, HR monitor strap, and manuals. Hub and rim as shown in the photos. Photo on the bike is only to show it installed, cassette and skewer in that photo are not included.This was originally a CycleOps SL+ power tap hub. I had it rebuilt by Powertap 2 years ago where they replaced the electronics and upgraded it to a G3. Has been working perfectly with my Garmin 500 and with two different Joule computers.
