i wuz speaking with a shop mechanic about chain lube when he offered
an opinion on it.
He said 7/8 of 10 bikes sold new were component trashed during the
first year by owners neglect, supidity, general lack of knowledge,
ignorance. I don't know but assume the wear factor goes up as price
when weight goes down.
not that components aren't replaceable but what effectively happens is
efficiency decreases gear by gear, lateral force potential, ...
countering efficiency loss toward improving or maintaining efficiency
is the idea.
