Seems like an awful lot of work for minimal savings. I've found that a
normal chain in normal use, not cleaned as often as it should be, is
generally good for 1500-2000 miles. Replaced that often, the rear
cassette
is usually good for 5 chains (so up to, say, 10,000 miles) and the
chainrings up front often go further

than that.

The cleaner you keep the chain and drive train the longer the chain will
last.
I have found that I can get around 4,000 miles out of a chain and I change
them
before they "stretch" much. I have heard somone claim that they could get
something like 15,000 miles out of a chain but they cleaned it after every
ride.

OK...speaking of clean chains...what's everyone's impression (that's used
them) of those contraptions that clip over your chain and contain brushes
and a reservior to clean your chain as you run it through the machine? Is
it faster (but as good as) using white lightning and a handheld brush with a
cleaning cloth (and screwdriver to get in the hard to reach spots with the
cloth?
