Just getting back into cycling, been riding progressively more for the last few months, I took my bike into a newer shop (supposed to be very good, old one I dealt with closed last year). Just wanted a general overhaul/maintenance, got the hubs repacked with new balls and got a new chain put on (SRAM pc68? old one was Shimano). The old chain was supposedly somewhat stretched but not badly so.
Now, first ride since I got it back from the shop, it's unrideable. Chain slips off front 3 times over first mile. Then starts making funny noise every few revolutions. Then starts slipping every few seconds while climbing. So either the chain doesn't fit, or my cassette/chainrings are too worn out? I wasn't having many problems with the old chain on, but now as I said, it's unrideable. Guess I should have just left well enough alone. It's an older mountain bike, with Deore DX 7-speed, so will it be a problem finding decent replacements if that's what I have to do? Really sucks, by the time I get it straightened out it will have been weeks since I rode and will probably not even feel like riding anymore. Just put on new Brooks saddle too which now can't ride to break in...grrr...frustrating.
