Shimano 600 appeared alongside Dura-Ace as the competitive core of the lineup, and the 6401 represents the mature end of that lineage before the 600 name was retired in 1997. Made in Japan, braze-on mount, clean tricolor finish \u2014 the right piece for a period-correct late 80s or early 90s road build.<\/p>\n<p><strong>Workshop Wisdom<\/strong> \u2014 Braze-on FDs require a brazed tab on the frame \u2014 not clamp-on compatible without an adapter. Set cage height 2\u20133mm above the largest chainring and align the cage parallel to the chainrings before setting limit screws. Bottom pull means cable routes from below \u2014 confirm your frame&#8217;s cable routing before ordering.<\/p>\n<p><strong>Guarantee<\/strong> \u2014 You put in the miles, we put in the work. 30-day guarantee on fit, function, and condition. \u2013 Paul<\/p>\n<p><strong>Keywords<\/strong> \u2014 Shimano 600 Ultegra FD-6401, front derailleur, braze-on, 8-speed, 7-speed, double, tricolor, tri-color, bottom pull, vintage Shimano, Japan, 600 Ultegra, retro road bike<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Will this work?
