Familiarity: I've put it through the wringer
My dad finally replaced the drivetrain on his 2012 Look. Five years of riding 3-4 times a week at 25-50 miles each ride. Not too shabby old man! Yes you a pay premium for Italian steel but it has held up to the Minnesota humidity, rain and sun for five years. No complaints, just time to reinvest.
Best to replace the whole drive at once. Chainrings, chain and cassette.
