- my power readings on the bike were quite high. It was showing that I was riding at ~500 watts where it should have been around 250 watts according to my garmin bike computer. Is there a proper way to sync the qollector to the power meter or do a zero offset? Is there any way to see the zero offset number with the qollector?
The qollector and the garmin should be showing the same numbers, since they are just reporting what the quarq is reporting. The garmin tells the quarq to do a zero offset, and the quarq will then use that new offset, the garmin does not use that offset number at all. So you should only need to do the zero offset from one device.
Did it show an average of 500 watts or just briefly show 500? Because on your garmin are you showing instantaneous power or 3 second or 30 second average power? Because maybe the garmin does not show the 500 watts because it happened so fast. Look at your power profile from the race, did you spend any time at 500 watts? Or I suggest your new FTP is at least 600 watts.
Not that it matters but I have an SRM, not a quarq.
I'm pretty certain that my SRM does not store the torque zero OFFSET. It does store the calibration factor (which also gets sent to the head unit and can be changed) but not the offset. The head unit (in my case an edge 520) stores the zero offset number which is the number (in hertz) that the SRM is outputting with no load applied (not clipped in). All the power meter is doing is reporting in hertz, the amount of deflection in the strain gauges. So I would expect any device that is collecting power data, to have to do a zero offset. When I do a zero offset with my edge 520 and then my 920xt, I don't get the same offset numbers.
Back to race.... the edge 520 reported perfectly. I averaged 238 watts according to my edge 520. The qollector showed I averaged 524 W which is impossible (and a max of 809). Avg cadence looks to be spot on for the qollector at 87 rpm's.
I just thought about it but there should also be a way to ensure the qollector is collecting zero's as compared to non-zero's power data.
