I never take a chance with dried brake pads, old tires, wear on cables. Stopping well is my component priority.
I have been remarkably lucky with 35+ year old components. Close inspection upon initial cleaning and reassembly is king.
Another benefit of a large fleet = once cleaned, inspected and installed - the bike will be a relatively low mileage rider given the rotation cycle. Also means more than the tire pressure gets checked before a ride.
