Hi all,
I don't know if I'm the only one, but I believe the cable routing of the rear derailleur really sucks. A lot of cable rub against the rear triangle. And I believe Giant thougth so to since they changed the routing on the 2021 if I'm not mistaken.
So since I also needed to change casette, chain and chainring, I decided to take an educated gamble and try a mix with SRAM / Shimano.
My setup :
- Deore CN-M6100 12-speed Chain with Quick-Link 138 Links
- Shimano Deore CS-M6100 12-speed Cassette 10-51 (all steel, better in my opinion for ebike)
- SRAM GX ASX
I took deore, well, because it is steel, and we all know : steel is real
( and also not unimportant, WWWAAAYYY less expensive than anything else)
To make a long story short, this works like a charm. Almost didn't have to touch the B-gap screw or do any micro adjustment. Just watch the youtube videos of SRAM on how to install. It's all the info you need. However to use the B-gap alignment tool, watch this video :
With regards to chainlenght, if you're not sure make it a bit longer, you can easily shorten a chain, the other way around though, ...., not so easy
I didn't encounter any issue or experienced any mishap. It's all straightforward, just take your time 
Just one thing, IF you use the quick link supplied with the Deore chain, listen to what the box says and DO NOT REUSE IT !!!!!! I did, and the link snapped after 2 minutes of riding ??
Stay safe but have a blast !!
