@ascentale @Cyclist @bikenite A3. I think the answer is personal, i.e. check your heart and wallet. Anything on a bike can be fixed. If a steel tube has failed, it can be replaced.
However, the intersection between cost and is it worth it is an answer only you can find (and it is probably in a fuzzy grey area).
I’m currently collecting the bits to rebuild a frame from ‘91. I will spend way moe than I paid for it, most likely more than an equivalent new bike, but sentimentally I don’t want to let it go. I’ve ridden this bike on three continents. We have a history together.
Good luck! #BikeNight
