I run a Bkool Pro smart trainer but the power measurements come from my Assioma power pedals. This eliminates the need to worry about any calibration on the Bkool and spin down nonsense.
At the start of EVERY ride, as I start to turn the pedals the power starts measuring and there is a low target power. Almost immediately I am on the correct power and ready to go. The issue is that I can feel the Turbo resistance biting and I have to push quite hard right at the start. (for a warm-up) It can take 1-2 minutes for it to sort itself out.
This only happens right at the start and for the rest of the ride, the speed of response is bang on. Even for a 5-second power surge, The software, pedals and Turbo are all working really responsively.
Below is an example ride. The start came under control quite quickly but I used this as you can see some 5-second surges and 30 rests that the work perfectly.
On the basis that TrainerRoad is getting the power from the pedals and then controlling the turbo, this seems likely to be a TR issue.
It’s not the end of the world and more an annoyance but I’m interested if anyone else has seen this or knows what might be going on.
