"Easy fix if you've got the tools"
... usually a stuck seatpost or stripped fork or bb thread![]()
"Five minute job if you know what you're doing" aka five hour debacle once you realize how shot it is, or it is actually a five minute job but requires fifty quids worth of parts and another fifty of tools.
"Kept in storage for x years" chucked in the back of the garage twenty years ago, probably reversed into a few times, might find a BSO under decades of cobwebs, dust and dulux splattering.
