I have upgraded my gravel bike from Ultegra to GRX and have removed my Stages Ultegra 8000 based crank (right) side power meter. Power Meter was purchased from Stages in Oct 20 and has less than a couple hundred on it. Purchase price was $450 and am looking for $400. Will bring with me for my Hopewell Church rides if anyone is interested in viewing. If interested you can email me at firstname.lastname@example.org or by phone at (540) 845-2524.
