'Allo folks. Went for a ride this evening and noticed my non-drivetrain crank arm had some play. I de-saddled and examined closer: the crank arm plays and moves 1/4 of an inch away from the frame. The other arm is not loose at all.
I took the cap off and saw a rusty (and loose) crank bolt. I finger-tightened it and rode home.
1. Is this an imminent sign of my bottom bracket dying? It could be the original -- it's a 70's Italvega.
2. I have some tools coming in at the end of the week and will be able to re-tighten it. After finger-tightening it, there was still play. Bad sign?
