Quick question. I purchased a new Cannondale Super Six Evo Hi-Mod a few weeks back. I have done maybe 500 km, mostly all done on a trip to the French Alps and no indoor trainer use, and have noticed that that the axle nut on the drive side which connects with the frame has scored it as per the photo. Is that normal wear after such a short period of time? I am running with Zipp 303 with the 188 hub V8. I just want to check as my old frame, which this replaced, had the drop outs totally ground down after 7 years of very hard use, largely I had thought because I had not tightened the QR on my Kickr hard enough . I am therefore super paranoid and wanted to gauge if people think this is normal wear after 500 km ?
