SunTour Fahrradbauteile: Unterschied zwischen den Versionen

Then came the New Winner: the same body could build 5- 6- or 7-speed clusters. The New Winner used the same threaded sprockets as the Perfect and Pro Compe, except for the outermost one or two sprockets, which attached at a new and different, smaller threading. In the wide 6-speed version and the 7-speed version, the outermost sprocket was threaded to the next sprocket, rather than to the body.

The New Winner had adjustable bearings, using a special pair of pin wrenches; there was a cone and a locknut, basically as with a bicycle hub bearing. The New Winner would go to a 12 tooth sprocket in the 7-speed version. The splined sprockets for the New Winner had shallower splines than those for the Pro Compe and Perfect, and were not available in the largest sizes -- but it was easily possible to adapt Pro Compe and Perfect sprockets by filing or grinding the splines. One unfortunate limitation was a result of the New Winner's being marketed as a racing freewheel. The largest threaded sprocket had only 21 teeth. while there were only two splined-sprocket positions. For this reason, it was hard to build up a freewheel with a reasonable progression and a wide range. There were a couple of ways around this problem. An aftermarket threaded-to-splined adapter was available for a while -- and also the integral spacer of a 15T threaded sprocket would pop neatly into place inside a splined sprocket. Spot-welding the two together made a large threaded sprocket..

The New Winner lent itself to customization, as shown in the two images below.

The Winner Pro went back to conventional shim-adjusted bearings, but was better sealed than previous models. The Winner Pro also had more splined sprockets and fewer threaded sprockets. The Winner Pro briefly offered an 11 tooth option in the wide six format. The Winner Pro also introduced the 4-prong extractor (previous models used 2 prongs.) There was also the Alpha series, basically a cheaper version of the Winner Pro.
