I’m continuing to stock up on spare parts due to shortages from our world wide supply chain apocalypse. I’ve had good help here in the recent past ordering the correct specs for brake pads, rotors , cassette etc.

Next on the list is a spare front chain ring.
I think I found the correct one just need help identifying it to be sure. My trek is the allant 8s frame size medium with the gen 4 motor speed motor.
Here’s the link to what I think is the correct one but it has different sizes and I’m not sure which size to get.

I’m pretty sure the chain ring on my ebike is 46tooth but the size either 94mm or 104mm I’m not sure.
Any help appreciated.
