Sure sellers/manufacturers can use teir good will and replace it anyway if they feel so or if you are very valuable customer, but generally it is as I said, crash damage = no warranty case ...
I think it's just the same thing if you do OTA update by yourself using MC app ... unless you are planning to run smaller wheel on the back then only LBS can change wheel circumference so that your cutoff speed matches your regulations ...
Yes, 170mm fork can void warranty of your frame.
I dig a bit deeper into this and yes! There is all gear data in the .fit file but GC does not support it, if you upload your .fit file to axs.sram.com you can get gear data displayed in a diferent reports like this:
Basically they are the same motors, with 2020 model you also have 4 years extended warranty on the motor (from the date of purchase), with 2021/22 only 2 years.
If you mean if data about current gear is saved into .fit file, I don't know and I doubt it. It is certainly not displayed in GC, on the other hand you can display battery % and support mode in GC if you send Ebike datafiled app author a small donation ...
EDIT: apparentely it does save gear...
No way the base comes with 700wh. If that's the case then base is a no brainer. I ended up replacing brakes, fork & drivetrain on Comp 2020 anyway, but I wouldn't want to be without 700wh battery ...
Yes, you can show battery % and support mode using Ebike filed datafield from @JanCapek, all other data (cadence, speed etc.) can be shown by adding bike as a sensor ...
