During my ride this afternoon, I noticed my fork has developed 1-2mm of play in it that wasn’t there before. Its definitely noticeable during breaking. I came home and checked everything I could (top cap, stem, etc) and everything is torqued to spec. Is this due to a lose starnut (I don’t have a starnut tool)? I looked through the Cane Creek manual, but that didn’t help much.
Info: '09 P2 with the standard integrated Cane Creek headset.
