| Re: Cleaning your bike...
Someone already touched on this -- the mechanic at my LBS said that
WD-40 is petroleum-based and thus degrades plastic parts, such as
derailleur pulley wheels. Said plastic wheels have indeed degraded on
my 8-year-old mountain bike, but I don't know if it's because of WD-40
or just age.
I started using a non petroleum-based lube spray (smells a bit like
butter) on my road bike's drivetrain, but haven't used it long enough
to notice a difference.
