I’ll reserve waste of money judgment until I know the frame. An old Moots, Fat Chance, Merlin, or Race Lite can command some dollars these days if in excellent original condition.
As for wheels, Rhyno Lites on lower end hubs are probably running $200.
None of this changes that it is still an older 26er, but value on almost anything vintage has nothing to do with comparable performance to modern standards. If it did, the classic car market would collapse.
