My bike makes this god awful squeek sound when I am pedaling, reminiscing of a dirty old serpentine belt on a car on a cold morning. Please help me figure this out.
Pedaling forward makes the noise. Pedaling backwards (no load) does not. Coasting also does not produce the noise (not the wheel bearings or hubs).
While my chain was super rusty after the winter, I cleaned it and lubed it several times and it looks really nice now. Chain is freshly lubed from earlier this week (no rain since).
I sprayed some lube on either side of the Bottom Bracket this morning just in case and it did not help.
Would it be possible that the chain is rubbing against something in the jockey, cassette, rear derailleur area? Would this not prevent me from shifting?
The bike shifts really well since I tuned it after winter.
Please help, this is really driving me NUTS!
