Cyco said:In a recent issue of Bicycling I came accross the followiing advice:
"Over-lubing accelerates drive-train wear, so apply a medium-weight
oil, such as Finish Line Cross Country Lube, onto a clean chain one
drop at a time. Then reapply only when the chain starts to squeak or
show any sign of rust"
Is it possible to over-lube a chain and how does this acclerate chain
wear? What constitutes over-lube? Also, is it sensible to wait until
the chain squeaks?
Any views on this would be appreciated

SRAM's current product information sheet merely states:
Maintenance / care
Regular lubrication will extend the chain's service life. Apply oil
to the chain links rollers and allow to work in. Clean dirty chains
before oiling. Do not use any grease-dissolving or acidic agents.
Cleaning agent must be rinsed off after a few minutes
with water. Apply oil after chain is completely dried.
Various other (sometimes conflicting) opinions and instructions have
been circulated widely.
My opinion: Chains are expendable and mostly inexpensive. Use your
own experience as a guide in determining how often to lubricate. Good
results (as determined by the persons reporting them) have been
reported with a multitude of lubricants and methods, varying from
nearly negligent wipe-and-oil-when-noisy practices to incredibly
exacting, tedious and time-consuming regimes involving multiple steps
and products.
One additional caveat: If the chain is from SRAM, and has never been
cleaned with solvent or other degreasing cleaners, it may be
counterproductive to clean it in that manner. One test, done by a
regular to this newsgroup, found that the chain wear rate went up when
an SRAM chain was cleaned using a technique that stripped the factory
lubricant.
