SunTour Skitter (3rd style)

SunTour Skitter derailleur (3rd style) main image

With the release in 1968 of the SunTour V and the SunTour Honor, the SunTour Skitter found its new place in the SunTour product range - at the very bottom of the heap. Commensurate with this status it looses its adjustable pulley cage and the rear knuckle becomes a steel pressing - a scaled down version of the Honor’s knuckle.

It retains the two trademark features of SunTour’s in-house Skitter designs - it is low-normal (what Shimano now call ‘rapid-rise’) and it had only one spring, which, through devious design, provides both chain tension and operates the parallelogram.

It also retains its proud membership of the pantheon of derailleurs with silly names.
