chain ring replacement

[peter brown]

hi i have the 2018 meta power race and in the process of dumping the ex1 drive train for a gx 11 speed setup. i will want to change the chainring at the same time but unsure what i need to order, is it 50mm or 53mm chain line? 104 bcd or direct mount on the e8000 motor. thanks in advance.

Shimano E8000?
Simply unbolt the shimano chainring from the spider and bolt on a new 104 bcd narrow wide chainring in it's place.

I just use £6 Alu NW rings from Aliexpress.
