I acquired a "TechnoGym XTPro Bike 600" from the gym at my old workplace but decided it is not right for me as I prefer a Turbo trainer or spin bike instead. I have to admit that this is not right for a serious triathlete but more suited to an unfit person who needs to build up a little sweat and get some feedback from the bike. It is Polar compatible and provides all the usual Time/Cadence/Watts/Heart Rate/Calories and Speed information. The unit is about 10 years old but is a professional piece of kit and should last for another 10 years. Please note that this is quite heavy and I wouldn't want to take it upstairs to a spare bedroom!
This is free to a good home/club and I will even deliver it in the Hillingdon/Gerrards Cross area. I will try to upload photos but you can see them on my Facebook wall too.
