If I get off the bike and try to spin the cranks backward, it's slightly too tight, doesn't spin freely. If I loosen pinch bolts and back off the preload cap, then tighten the pinch bolts back down, the crank will spin freely, and the noise will disappear. But after 2-3 short rides the BB bearing is too tight again. What am I doing wrong?
Is it at all possible that your bottom bracket was not pressed in properly and is working its way out? Look closely where it meets the frame and make sure it’s still pressed completely in.
