Help.. Rear derailleur wrong position?
#1
I've tried searching for YouTube assistance but to no avail. Cycled to the shops this morning and the gears weren't functioning, had a look and something has gone horribly wrong. It's as though the chain is suddenly inches longer than it should be and it isn't holding any tension unless the derailleur sits all the way back (image attached) almost so the chain is touching itself as it travels through. Is this an easy fix or will it need replacing?

Hi there,
I have the same thing happen. Did you find out what the problem was?

This did not just happen overnight. The drivetrain is plain worn out. Take a close look at the jockey wheels on the derailluer. the teeth have worn down to little points. By the way the rest of it looks to be maintained, I would recommend replacing the rear derailluer, chain and rear cluster. roughly around $100us dollars + labor as long as the chainrings are in good shape
