Yep I understood that, just mentioning I would use a beefy chain lock on the beater.

I fixed the shifters so it's not jumping gears anymore. What are the signs of a bad chain? It feels like the springing back is in the BB or from the rear derailleur. Alot of slack builds up on the top of the chain when I pedal backwards. Also, when the bike is upside down, the rear wheel slows down very quickly, it doesn't coast much. Is it bearing repacking time?


Regarding the water idea, I spent an hour with an anchor and long rope dragging around to feel for my bike, and nothing. My uncle dove down along the rope and saw nothing, except the chain to the dock. (15-20 ft deep) I pulled the drop bars around the railing so it coudn't roll anywhere.
