Noisy wife ..

Hi All,
Well, not the wife (this time) but her exercise bike ;-)
It's quite a nice Tunturi Ergometer 420 (she's getting ready for when
we go out on our solo's / tandem this year) but it squeeks a bit now.
It uses a flat, toothed belt (like a cambelt) to drive the magnetic
'friction' flywheel and as that gently drifts against the guide /
tension rollers it gives of a sort of rhythmic squeak.
The makers suggest the use of talc (on the drive belt g) and that
does work but not for very long?
I believe the front toothed wheel is a sort of plastic / nylon as is
the (smooth) tension roller but I think the rear drive gear / roller
clutch is alloy.
Any tribologists out there?
All the best ..

Ah but Tim, just think what the neighbours think you are up to for hours
with that rhythmic squeak - curing it will hit your street cred hard!
