A bike so quiet all I hear is wind in my ears....totally lovely. To think that one dry chain link or squeaky shoe/pedal interface can disrupt such harmony. Its not a fastidious compulsive thing......its that desire for completely interlocking peace, and because, unlike runners, we are a human/mechanical hybrid when riding the bike, we want it to work as effortlessly as (we wish) our bodies do. In fact, maybe our bikes become a kind of alter ego. [This is getting too deep for me...but yes, I love a quiet bike.]
