The real party trick here is the AccuShift Plus dual-mode: run indexed when everything plays nice, flip to friction when it doesn&#8217;t. Rare enough that vintage builders actively hunt them. Silver finish looks sharp on a period-correct build.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"><strong>Workshop Wisdom:<\/strong> AccuShift indexing uses a different cable pull ratio than Shimano SIS \u2014 in indexed mode, these pair correctly with Suntour derailleurs only. In friction mode, the cable pull is irrelevant and they&#8217;ll work with virtually any rear derailleur. When in doubt, run friction and enjoy smooth, forgiving shifting on any drivetrain.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"><strong>Guarantee:<\/strong> You put in the miles, we put in the work! 30-day Guarantee, rest assured of fit, function and condition. \ud83d\ude42<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"><strong>Keywords:<\/strong> Suntour Radius downtube shifters, AccuShift Plus, 6 speed, 7 speed, indexed friction, vintage downtube shifters, early 90s, braze-on, clamp-on, Suntour groupset, road bike shifters, Japan<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Will this work?
