Hi, I have a power tap wheel that was given to me by a sponsor that I don't use any more. I would consider selling it. It comes built to a Mavic open Pro rim with 32 14/15/14 double butted spokes. Works perfectly. Do you need the entire kit? (computer, harness, software, and data cable) Rick
Let me know how much you figure the package is worth - I don't really know what it goes for new. I think I have an Ultegra cassette too if you need it.
