recommendation / tip - for long term storage of bikes
coat of wax on the frame
a light spray of lubricant (tri-flow, wd-40, whatever) into the shifter assemblies if they are Shimano dual control / STI (‘brifters’) or Rapid Fire or similar
the factory lubricant (light grease ?) in the Shimano shifter assemblies will solidify and the shifters will not operate correctly after sitting for a couple of decades
( most times few squirts of liquid lubricant - sometimes over a day or two - will recover the operation ... sometimes liberal use of liquid lubricant is required )
