Put almost 7,000 on mine before selling it. I had a good experience. Had a spoke break but that was the only issue. The wheels needed a proper trueing out of the box. The Rohloff oil change kit comes with the stuff you need https://a.co/d/03coJikk After that you can just buy the shimano oil. The belt drive doesn’t need to be as tight as the app will indicate. Shimano’s 11 speed isn’t designed for the extra tension of the belt so err on the side of running it not loose, but not tight. Avoid exposing the belt to strong detergents like car wash detergents. They will sap it of its normal conditioning and it will make a squeaky noise. To fix this I ended up using a silicone based lubricant to recondition it.
