Modern chain made a big improvement. So the Vittoria tubulars and chain are the only new modern parts on it. I will most likely will install new shifter/brake cables as well when the riding season starts, but will try to keep the original housings. It rides okay, even brakes suprisingly well after installing some NOS xb3 brake pads, but not really a fan of these gran sport copy xb3 derailleurs, but they look cool atleast. Those square taper cranks gave the bike a new feeling, quite suprised by this.
