it was a demo at an "open-house" in one of the local bike shops-- TACX was there with their reps.
The system is basically a resistance trainer wired into a computer-- they had the bike wired for cadence and of course the power meter and speed was at the wheel, and there was also a HRM ... the data is picked up by the computer which also functions as the task master by giving you the visuals through a TV monitor and it also controls the resistance at the wheel to emulate the course. There was also analytic software for your performances.
...and they had all the major races on DVD, but everything was rendered in old video game quality visuals, your competition can either be some of your old performances (which redefines racing against yourself) or virtual superstars of your choosing.
the unit retailed for C$1800
then I'd need (want?) to feed the data to a new Dell 20" multimedia laptop with retails for C$3700
So I'm talking at the very least C$6000 with the stand and whatever else I'd need to put the thing together.
