@1k2go you are my hero! I wish I had found this earlier. I spent about 90 minutes last night trying to calibrate with both the TrainerRoad and Kinetic Fit apps. Did all of the troubleshooting: cleaned tire & roller, correct tire pressure, loosened acorn nut, etc. I kept tightening and tightening the bolt on the resistance unit until my hand hurt. Nothing doing.
I gave it another go today and eventually was able to get the Kinetic Fit app to spindown in 6.85 seconds. Moved on to TrainerRoad app but it continued to time out.
Then I searched the internet again and found your post! The very next attempt, I spun up to 26 mph and the calibration was successful.
The last time I calibrated with TrainerRoad was early last month (March). I don’t do it regularly because it is always a struggle. I took the bike off to lube up the chain and needed to go through the exercise again. I will change my habits know that I know this “trick.”
I thank you and my dining room table thanks you because I was probably going to flip it if I hadn’t found this thread. Thanks!
