Preparing for a big trip end of next week. New tyres needed..usually do these myself with the help of a friend with a tyre machine....but he's Ill so I went to a national chain advertising ride in ride out service.
Wish I hadn't..it took three of them an hour to get the back wheel in and I rode 59 miles home with an overtightened chain.
Readjusted this morning and now have a regular slight pulsing vibration through the boards at low speed under load.
My diagnosis is unevenly stretched chain....wheel is aligned OK and all running true.No broken rollers
Other diagnoses welcome
