For ages I'd just crank the locknuts tight and hope for the best. Then a guy at the shop in Bend showed me his trick: tighten the cone just until you feel a tiny bit of drag, then back it off a quarter turn. Did that on a customer's old Trek last week and the wheel spun smooth as butter. No more wobble. Anyone else have a better method for getting that adjustment just right?
What if that trick only works on some types of faucets? I've seen it fail and leave people with a worse drip. It feels like a temporary fix for a deeper problem.
