SR SUNTOUR CR800

SR SUNTOUR CR800 derailleur main image

For the 2004 model year SR SUNTOUR opened its first factory in China, in Kunshan. Amongst the first products were three derailleurs, the CR800, CR400 and CR300. I think that this example is the SR SUNTOUR CR800.

The CR800 was interesting in a number of ways:

  • It was low-normal, finished in rather smart silver paint and had very large pulley wheels. All of these features are reminiscent to Shimano's 'Rapid Rise' Nexave derailleurs of the period.
  • It used a very simple but innovative cable run, with two curved cable ramps.

I believe that SR SUNTOUR called their low-normal system the 'ICE' transmission - but I have not yet worked out what these letters stand for. It is also worth noting that the Dahon and Tern derailleurs, that SR SUNTOUR designed and manufactured, were also low-normal.
