good buyin Klein Quantum

i think this is good buying, id say a 57-58…Hoonz??

Klein Quantum 1980’s Men’s Road Bike | Bicycles | Gumtree Australia Melville Area - Palmyra | 1031225353

i built one up. they are nice but the weird press bottom bracket is a bitch.
why cant they use normal english threading.

Because Klein, be thankful it wasn’t a later one with the MC2 headset…imagine trying to find a stem to change the length or rise…
