File extension IMF description:
The Tacx Fortius Trainer is Tacx's showcase product, a Virtual Reality Trainer designed with a sensational braking system and completely new software. The possibilities of this interactive trainer are unlimited. The Fortius connects to a PC, operated via an interface on the handlebars. You can compete in races, freewheel at will, go on a voyage of discovery or undergo intensive, goal-orientated training. You can use the arrow keys to choose the rider and the team with which you want to ride. Whether it is a cyclist, an ATB rider, a man or a woman, the virtual riders all display natural movements. They are flexible, with nice pedaling actions and aerodynamic positions. These lively riders jump, cheer, ride standing up, change gears, snivel, drink from their water bottles and make spectacular falls. A multiple of options accentuates creative play. There are various types of clothing. You can choose from Liberty Seguros, Team CSC to ATB and fantasy shirts. There are also various racing bikes and ATBs, aerodynamic wheels with carbon rims or traditional wheels. You can even choose your own weather conditions. Wind direction, wind speed, day, night, sunshine, clear, cloudy, rain and mist - all affect cycling.
