I have noticed a number of '70s bikes, whose frames appear to have been made for short reach calipers, sporting normal reach calipers with pad holders in the tops of the slots. Were normal reach calipers installed due to some desired mechanical property of this arrangement?... or due to a some extended shortage of short reach calipers?... or was it just a fashion of the time?... Or...???
