coaster brakes! haha yes, i feel like we had this convo, but i love coaster brakes.
I mean, i do sachs pretty hard.
But playing with bikes, I would regularly lace up some 700s to coaster hubs. We sold those bikes, some to friends some to randos, but people liked it, mind you this was peak fixie fanaticism, Premium rush and all. Lace up a coaster hub to a "cool" deep v 700, slam it in a old steel frame with horizontal dropouts, and you got all the "cool" of no cables or deraileur, skids everywhere, AND YOU CAN COAST! very well recieved, I had fun doing it too.
