Just a note for those intending to do The Flying Fox Zip Line. At an altitude of just over 1300m and length of 1.6km long it has been superseded by the Zip Line Stoderzinken at an altitude of over 1600m and two stages of 1.5km and 1km long, riding 4 abreast: http://www.zipline.at/de/index.php.
You will find some nice roads around the area on www.bestbikingroads.com including the Stoderzinken Alpenstraße :-)
Just a classic Austrian alpine run with picture postcard views and a nice mixture of fast open bends and tight alpine twisties. Once you get to Saalbach Hinterglemm make sure you take the land train up to the highrope course and do the highest & longest zipwire in Europe! Brilliant
