Why is Velotron continually being brought into this thread? (I know for humor sake) :-)
I can understand comparing the Kickr to the Computrainer, but a Velotron trainer that the website currently states as $9,950 with a frame is not an equal comparison to a $1,000 trainer. I will agree that for the $1K+ that I spent I don't feel as if I got all the qualities (yet) for what I paid. Most of the attributes of the Kickr are working well for me and I suspect for many. It has a great feel to it compared to other trainers I have used.
The reason is because the Kickr is a Velotron light. There is no wheel, therefore there should be no reason to need continual calibration. With a Velotron it's calibrated once at the factory and you never need to do any sort of zeroing or calibration.
The reason a trainer tire unit requires calibration is due to press on force. None of that should affect the Kickr.
I love the concept of the Kickr. Racermate should have at least made a CT without a tire contact. No wires, open API is all great. What is not good is DRIFT. It's one thing if the kicker is just wrong, but CONSISTENT. This way you test on the Kickr and just do your workouts. But the up and downward drift is a HUGE problem. If I want to do an interval at 300 Kickr watts, it should be 300 Kickr watts at 20 minutes, 30 minutes, etc. etc.
Until Wahoo can give an explanation for what is being reported, it is best to stay away... Well unless you have a 2nd power meter and want to use that with the Kickr.
