>>1040152>Cartridge st or cup and cone either way its extremely oldschool tech. It's getting to almost be like running a cottered crankAh, that's the extreme comparison I love /n/ for!
I'm in the square taper camp, admittedly because I have a soft-spot for 90s MTB cranks, but mostly it has to do with riding conditions; external BBs have a laughably short lifespan in a place like Seattle. But really it all boils down to preference, ride what you like!
