I’ve just bought a pair of Favero Assioma Duos, having used Stages LR for the past 12 months. To see how much variance there is between the Assiomos, Stages and my turbo (Cycleops Hammer), I did a ramp test (not to establish my ftp but as a useful workout for covering a fairly wide range of watts).
Using ANT+, I had paired the Hammer to the TR app, the Assiomos (set to cadence only in the TR app) to a Garmin 820, and the Stages to a Garmin 520. The Assiomas and the Stages were calibrated before starting the workout, the Hammer 10 minutes into it.
I uploaded the three data files to DC Rainmaker’s analyser tool:
I’m baffled why the data from the Stages and Assiomas overlays each other in the graphs but the Hammer’s data only appears after around 14 minutes. I pressed start on the two Garmins as soon as the workout started in the TR app. According to the data uploaded to TR (which correctly shows the Hammer as the power source), the workout lasted 23 mins 8 secs.
I don’t understand why the data uploaded from all three devices to the analyser tool shows the workout in two distinct parts: the Stages and Assiomas for the first part and the Hammer for the second.
Any ideas anyone? Please don’t tell me it’s something really obvious
