I have a fairly old (8 years or so) specialized Allez with a Shimano 105 drivetrain which I now use
exclusively on my trainer. The drivetrain has about 10,000 miles of use on it. Lately I have been
getting a squeal (high pitched screech) when I use the bike on the trainer, particularly when I am
using certain cogs. Any views on how to fix the problem? Replace cogs (entire freewheel at this
point I guess)? Do I need to also replace the chain and the chainrings? Or could the squeal be
coming from the rear hub? It's hard to isolate the sound?
