Destroyed my front wheel in someone's quick release (my fault). Half of the 28 spokes were gone. Rebuilt the wheel with the remaining 14 on the side of the road & continued the remaining 25 miles of a century.
Rear derailleur pulley came loose on a ride recently. Fortunately the bolt & pulley were still there just loose from the cage. Repaired on the side of the road & used locktite as soon as I got home
