I’m using an older Tacx Vortex Smart for the past year or so and Favero Assiom with power match. I’ve been going through some of the 200% FTP sprint progression workouts in the half ironman base plans and seem to be RPM limited on the sprint power. I have pretty consistently handled ~520-540W (470 target) for the 20 seconds, but I always feel like I could handle more.
I am in the big ring (50t) and smallest gear on my cassette (11t). I am averaging ~130rpm for the sprints, and the resistance just kind of melts away. I turn off ERG mode ~10 seconds before the sprint interval.
Does anyone have any recommendations on how to go higher power indoors? Or is this just going to be a permanent limit of my setup?
