Sun Tour Symmetric shifters were an esoteric piece of early 1980s Japanese engineering. They could be mounted on frames with a single downtube shifter braze-on (like some of the Shimano AX components took) or with a supplied clamp-on belt. They are unique because shifting the rear derailleur automatically trims the front via a cam mechanism.[Sheldon regarded the design as flawed, but opinions differ -- John Allen] The video below, from N. Keith Duncan, shows the operation of this shift lever.
SunTour [[Symmetric ®]] Schalthebel waren ein etwas esoterisches Bauteil des [[japanisch]]en Ingenieurswesen der 1980er Jahre. Man konnte sie an Rahmen mit einem Anlötteil für Unterrohrschalter (so wie sie für Shimano [[AX]] Komponenten vorgesehen waren) oder mit der migelieferten Klemmschale montieren. Sie sind ziemliche Unikate, weil ein Nockenmechanimsus dazu gedacht war, den vorderen Umwerfer nachzujustieren, wenn man hinten am Schaltwerk schaltete. [[Sheldon Brown]] betrachtete das Design als fehlerhaft, man kann jedoch andere Meinung sein, meint [[John Allen]]. Folgendes Video von N. Keith Duncan zeigt die Funktionsweise des Schalthebels:

In 1981 Superbe Pro was introduced. Good stuff, the early to mid 80s Superbe Pro friction group is probably my favorite. Commands a premium price on eBay (I would know, I'm selling a group on there right now). Superbe was now second-best, with Cyclone below that. ARx, AR and BL (Blue Line, which featured interesting blue details on the components) were also introduced. Brakes and brake levers were rebadged Dia-Compes and I think the cranks and BBs were made by Sugino (all the ones I've seen come with a Sugino marked grease condom, in any case).
