This power meter was mounted and used for 1 ride. Other than that it has been sitting on a bike hanging in my garage. I'm only selling because I'm not riding that bike enough to justify a power meter on it. Anyway, it is in great condition and works as expected. All bolts are included. Asking $450 + 3% PayPal fees. I also have a 5 bolt Shimano rs500 crank if interested.
