Anybody typically run high mileage on their chains?
I have the stock chain on my Rival equipped 3 year old Lynskey R330 - a PC 1051 I think. Anyway it's got just over 19,000 miles with minimal "stretch" and still shifting fast, smooth and quiet.
I take meticulous, obsessive care of the drivetrain. I have a new chain and cassette but was wondering how much more life I could get?
