Tectoron KS-01

The Tectoron KS-01 is a Campagnolo Super Record recreated in Leipzig in the style of a Soviet Tractor. Fundamentally it is all there; it feels strong and tight, the pulleys spin smoothly and it is not that heavy. Unlike Favorit or Kharkov models it contains no steel or plastic major components - it is all aluminium. All well and good - but no opportunity to omit flair, charm or refinement has been passed up - it is a crude and brutish object.

The Tectoron KS-01 is shown on a few websites as being fitted to Diamant road racing bikes from about 1978 onwards. However the pulley cage plates are clearly a copy of the shape that Campagnolo only introduced on the 1979 Super Record - so either Tectoron had an earlier style with a different pulley cage, or the dates are a touch dodgy.

I particularly like this example because its pulley cage plates have an alluring industrial dimpled pattern on them. Note that the KS-01 also belongs to the select band of derailleurs with their logos upside down - see also the Sugino VIC.
