I have a Tacx Flow Smart (800w). I’m very happy with it, but how do I know whether I need to upgrade? Im following one of the 13 week training programs on Zwift (Build me up) Im having some issue on low cadence (65-75) and around 250-300 wattage - difficult for it to stabilise within the 30 seconds… it also struggles to measure my cadence when I stand-up. I also need to gear up to the highest gear to be able to get the low cadence on the required wattage. Is this normal with any smart trainer, or can I with a stronger smart trainer eg. 1500-2000 w follow the program without changing gears?
