According to Wikipedia ……….. An item should be at least 100 years old to be defined as an antique.
Generally speaking if the item is not older than an antique but not less than 20 years, it falls under the term vintage.
Well. from my point of view "whats wrong" is compatibility and the fact all my stuff in my stash is Shimano.
"There was a time when cyclists were free to mix and match transmission components, but that all changed when Shimano introduced indexed gear shifting in 1984. The new system provided very accurate shifting, but it depended upon precise compatibility of the shifter with the derailleurs and drivetrain.
Indexed shifting works because the rear derailleur travels a precise distance in response to a pre-set amount of cable pull within the shift lever. Cable tension is critical for accuracy, but the geometry of the derailleur and the sprocket spacing must match the indexed cable pull, otherwise the derailleur will not align with each sprocket.
Rather than work to a common standard, Shimano, Campagnolo, and SRAM have all developed their own specifications for their indexed gear systems. SRAM mechanical gear levers employ 1:1 actuation (1mm of cable pull moves the rear derailleur 1mm) while Shimano and Campagnolo use higher ratios (1.4 to 1.9:1). Thus, while it is physically possible to operate one brand of derailleurs with another brand of shifters, the quality of shifting will be greatly compromised."
The bike was in poor condition, but when I got it going it had some problems shifting and skipped in high gear. Chain was rusted solid and freed with pb blaster.
Longest test ride was a 15 mi loop around my house and the chain snapped. Turned out to be full of tiny cracks in the link side plates. Anyways good chain now and wear adjusted out of the bearings hope it shifts more solid. If I change out to a Shimano rear der I have lots of cool shifters in my stash (only 7 speed tho).
This may be best option for me as I can lock out the highest (skipping) gear.
