I am new to power based training and I did my first ramp test today.
I want to be thrilled with the outcome but I am skeptical. My pre-test estimate was 160 watts, which proved to be exceptionally low. The ramp test went for a full hour and I came up with an FTP of 414 watts.
Either I need drop everything and become a pro or something is strange. I just bought the Favero Assioma Uno second hand. It seems to be relatively precise as it would hold a specific wattage for a given effort but perhaps it is inaccurate.
I have no other power meter so I cannot verify whether this one is accurate or not. As long as it is precise I can use it for training but I just cannot believe that my FTP is that high. I weigh ~74kg which would give me 5.9 W/kg…
I guess I should just do more FTP tests to see if something was off? Not sure if I should try to return the power meter or just live with it and use it as a training tool and accept that it might be inaccurate.
EDIT: Ok, looks like I did not understand the use case for the “double power” setting in Assioma’s app. I thought you only unchecked that if you converted the Uno to a Duo. Seems like most head units / software know to double the power from a single sided unit without this setting… so it only exists to rectify a situation where your power is not doubled after transmission.
Glad to have figured this out. I am definitely a mere mortal, haha.
Ok… things might not be so simple…
It seems that doubling the left side in the assioma app only applies to BLE. I unpaired the pedal with my Edge 530, reset all of the parameters correctly in the assioma app. (no doubling) Then I paired with the 530, set it up correct (with correct crank arm length) and then calibrated.
I was still seeing the same power numbers as before. This makes sense as Favero says the doubling feature is only for BLE, not ANT+.
I used some online power / velocity calculators and things seem to add up. If I go ~25 mph on the flat, the head unit reports ~330 watts from the pedal. (Me + bike = ~85kg)
Despite being told by TR that the Assioma Uno’s power is not doubled by the TR windows application, my first ramp test was definitely close to double my actual FTP.
I ordered an ANT+ stick and connected the Uno with that this morning to do a 20 minute FTP test instead of the ramp test and I ended up with an FTP of 233 watts. (A bit over double the 207 that would have been predicted by halving the amount for the first ramp test) Not sure about the 25 watt discrepancy… may just have been a calibration issue or perhaps the crank length was incorrect the for the first test.
While this is slightly disappointing am I glad to have a better approximation of my true FTP so that I can begin training. I tried one day of training with an FTP of 414 watts and could not even hit the targets. That whole day must have been in VO2 max or higher… so who knows if that may have affected today’s result. On the bright side, I have plenty of room to grow!
So here is my recommendation to new TR users who have Assioma Unos: Buy an ANT+ stick and connect with that so there is no chance of quadrupling the power reported from the left pedal.
