I am new to Zwift and just got a new Saris H3 that I use via bluetooth apple 4k tv. I have been using for a little over a week and put 110 miles on so far. I have a few issues that keep coming up from time to time. One I have never been able to do the spin down calibration on Zwift always have to use my Saris App. It has me get to 23mph and says to keep pedaling but I crash (physically) before it ever has me stop and spin down.
Bigger issue is at times I will be going up a 6% hill and it is easy and other times I am going downhill and it is very hard. There does not seem to be any pattern to when it happens. At times I will ride 20 miles without an issue other rides it seems nonstop.
Any thoughts or advise???
