With a clever cable route, a relatively low price, exceedingly light weight and with a great shift, the SunTour Cyclone GT was a miracle. To this day the Shimano XTR is heavier than this Cyclone GT - proof of the simple purity of the single-sprung pivot slant parallelogram design.
The second style of SunTour Cyclone had a slightly redesigned rear knuckle and a captive short hanger bolt (with a distinctive serrated edge).
Typically for touring Cyclones, this example is well used. The SunTour Cyclone GT was not just for decoration or a talking point - it was the gear of choice for many a cycle tourist setting out from Britain to Istanbul or wherever. For the cognoscenti it was what you fitted on your hand-built Mercian or Bob Jackson - only blow-hards opted for Campagnolo. I loved it.
