Suntour Cyclone Rear Derailleur: Silver 1st Gen 1977 Upgraded Sealed Bearing

This derailleur has upgraded Suntour sealed bearing pulleys!  They are the same pulleys used on some Suntour Superbe Pro derailleurs.  They spin much smoother than the stock pulleys, and feel like they're spinning on ice.  Introduced in 1975, the Cyclone model was Suntour's first venture into the high end road market, and was a direct competitor of the mighty Campagnolo Nuovo Record.  In fact, it was lighter and better performing than the Campy derailleur!  At 179 grams, this is considered one of the finest friction derailleurs ever made.  The entire derailleur is hignly polished, and finely machined.  

Condition:  Excellent shape.  Cage is straight and tight, pulleys are smooth as butter with practically no tooth wear.  Some minor scratches on body.  The lower left knuckle has a light scuff, and the tension spring casing near the lower pulley has a scratch.  The black anodizing on the faceplate is very slightly worn.  It's not quite as nice cosmetically as the other 2 Cyclone's we're selling (See below), but with the upgraded pulleys it's a great deal.
