>>1185225First wave happened during the 50s and 60s in competitive time trial events, where derailleurs were a meme for being heavy and slow. Some even criticized other time trialists with slow times and derailleurs. Ironic because nowadays fixed is a meme and criticized for compromising gearing range. Way before my time and I'm sure the majority of us here but technically considered 'first wave.' OG fixfags were from the late 1800's riding some of the first modern bikes ever made but that's fully a technological limitation.
