I've been riding through some snow, ice and salt all winter so far. Today my bottom bracket started making a sound like it's rubbing metal to metal with no grease. It still spins okay so I don't think it's completely shot, anyone I haven't taken it a part yet to look at it. Should I pull my cranks? If I take my back wheel and chain off and just spin the crank arms it doesn't make a noise at all. Maybe I need a new chain or just need to clean it? Any advice?
Thanks for all the help gentlemen, I cleaned the heck out of my chain and lubed it. Took the back wheel off and adjusted the hub and it's spinning for days now. It's still noisey but what can I expect after riding through winter gunk, I'll worry about cleaning everything down another day.
