yeah my old tourer frame has diacompe mafac copies but I want drum brakes
I have heard the rollers aren't completely sealed like the sa drums and they are smaller so your stopping power and stopping consistancy is lost in adverse weather conditions
also I am a huge fan of the old school rando porteur mechanics and what not seriously my old tourer is going to be more reliable than any one of my three fixies and it will have gears and mechanical brakes
