Cutting q-rings to fit quarq dzero?

[dairic]

Hi,
I've got a dzero with q rings set on ocp 3, I went to change them last night to #4 and noticed that a piece had been taken out of the inner circle of the outer ring to accommodate the battery pack. If I want to change it to number 4 I will have to do the same on the opposite side. Will this or has this affected the strength of the q ring?
Cheers

No, thats no problem. The Aero Q-Rings are strong enough! It is only a cosmetic issue. I already have modified my Q-Rings for the Dzero spider, but P2M is my favorite powermeter.

Is the non-round DZero firmware update available already?

No, unfortunately not:

As I understand it mostly just involves increasing the cadence polling rate to account for the acceleration of your cranks through the dead spot.
